RESUMO
OBJECTIVE: Determine the rate of documented notification, via an alert, for intra-institutional discrepant radiologist opinions and addended reports and resulting clinical management changes. METHODS: This institutional review board-exempt, retrospective study was performed at a large academic medical center. We defined an intra-institutional discrepant opinion as when a consultant radiologist provides a different interpretation from that formally rendered by a colleague at our institution. We implemented a discrepant opinion policy requiring closed-loop notification of the consulting radiologist's second opinion to the original radiologist, who must acknowledge this alert within 30 days. This study included all discrepant opinion alerts created December 1, 2019, to December 31, 2021, of which two radiologists and an internal medicine physician performed consensus review. Primary outcomes were degree of discrepancy and percent of discrepant opinions leading to change in clinical management. Secondary outcome was report addendum rate compared with an existing peer learning program using Fisher's exact test. RESULTS: Of 114 discrepant opinion alerts among 1,888,147 reports generated during the study period (0.006%), 58 alerts were categorized as major (50.9%), 41 as moderate (36.0%), and 15 as minor discrepancies (13.1%). Clinical management change occurred in 64 of 114 cases (56.1%). Report addendum rate for discrepant opinion alerts was 4-fold higher than for peer learning alerts at our institution (66 of 315 = 21% versus 432 of 8,273 =5.2%; P < .0001). DISCUSSION: Although discrepant intra-institutional radiologist second opinions were rare, they frequently led to changes in clinical management. Capturing these discrepancies by encouraging alert use may help optimize patient care and document what was communicated to the referring or consulting care team by consulting radiologists.

PURPOSE: To compare thoracic and abdominal radiologists' follow-up recommendations for abdominal findings identified on chest CT. METHODS: This Institutional Review Board-exempt, retrospective study was performed at a large academic medical center with subspecialty radiology divisions. We used a combination of natural language processing and manual reviews to identify chest CT reports with and without abdominal findings that were interpreted by thoracic radiologists in 2019. Three random samples of reports were reviewed by two subspecialty trained abdominal radiologists for their agreement with thoracic radiologists' reporting: abdominal findings with follow-up recommendation (Group 1), abdominal findings without follow-up recommendation (Group 2), and no abdominal findings reported (Group 3). Primary outcome was agreement between thoracic and abdominal radiologists for the need for follow-up of abdominal findings. Secondary outcomes were agreement between subspecialists for the presence of abdominal findings and referring clinician adherence to recommendations. Fischer's exact test was used to compare proportions. RESULTS: Abdominal radiologists agreed with need for follow-up in 48.5% (16/33) of Group 1 cases and agreed follow-up was not necessary for 100% (34/34) of Group 2 cases (p < 0.001). Abdominal radiologists identified abdominal findings in 31.4% (11/35) of Group 3 cases, none of which required follow-up. Referring clinician adherence to thoracic radiologist follow-up recommendations for abdominal findings was 13/33 (39.4%). CONCLUSION: Abdominal radiologists frequently disagreed with thoracic radiologist recommendations for follow-up of abdominal findings on chest CT. Chest radiologists may consider abdominal subspecialty consultation or clinical decision support to reduce unnecessary imaging.

PURPOSE: Brain metastases can occur in up to 50% of patients with metastatic HER2-positive breast cancer. Because patients with active brain metastases were excluded from previous pivotal clinical trials, the central nervous system (CNS) activity of the antibody-drug conjugate trastuzumab deruxtecan (T-DXd) is not well characterized. EXPERIMENTAL DESIGN: We studied how T-DXd affects growth and overall survival in orthotopic patient-derived xenografts (PDX) of HER2-positive and HER2-low breast cancer brain metastases (BCBM). Separately, we evaluated the effects of T-DXd in a retrospective cohort study of 17 patients with stable or active brain metastases. RESULTS: T-DXd inhibited tumor growth and prolonged survival in orthotopic PDX models of HER2-positive (IHC 3+) and HER2-low (IHC 2+/FISH ratio < 2) BCBMs. T-DXd reduced tumor size and prolonged survival in a T-DM1-resistant HER2-positive BCBM PDX model. In a retrospective multi-institutional cohort study of 17 patients with predominantly HER2-positive BCBMs, the CNS objective response rate (ORR) was 73% (11/15) while extracranial response rate was 45% (5/11). In the subset of patients with untreated or progressive BCBM at baseline, the CNS ORR was 70% (7/10). The median time on treatment with T-DXd was 8.9 (1.3-16.2) months, with 42% (7/17) remaining on treatment at data cutoff. CONCLUSIONS: T-DXd demonstrates evidence of CNS activity in HER2-positive and HER2-low PDX models of BCBM and preliminary evidence of clinical efficacy in a multi-institution case series of patients with BCBM. Prospective clinical trials to further evaluate CNS activity of T-DXd in patients with active brain metastases are warranted. See related commentary by Soffietti and Pellerino, p. 8.

OBJECTIVE: This study aimed to determine effect of modality, care setting, and radiology subspecialty on frequency of diagnostic image quality issues identified by radiologists during image interpretation. METHODS: This Institutional Review Board-exempt retrospective study was performed 10/1/18-6/30/20 at an academic radiology practice performing 700,000+ examinations annually. A closed-loop communication tool integrated in PACS workflow enabled radiologists to alert technologists to image quality issues. Radiologists categorized communications as requiring patient callback, or as technologist learning opportunities if image quality was adequate to generate a diagnostic report. Fisher's exact test assessed impact of imaging modality, radiology subspecialty, and care setting on radiologist-identified image quality issues. RESULTS: 976,915 imaging examinations were performed during the study period. Radiologists generated 1,935 technologist learning opportunities (0.20%) and 208 callbacks (0.02%). Learning opportunity rates were highest for MRI (0.60%) when compared to CT (0.26%) and radiography (0.08%) (p<0.0001). The same was true for patient callbacks (MRI 0.13%, CT 0.02%, radiography 0.0006%; p<0.0001). Outpatient examinations generated more learning opportunities (1479/637,092; 0.23%) vs. inpatient (305/200,206; 0.15%) and Emergency Department (151/139,617; 0.11%) (p<0.0001). Abdominal subspecialists were most likely to generate learning opportunities when compared to other subspecialists and cardiovascular imagers were most likely to call a patient back. CONCLUSIONS: Image quality issues identified by radiologists during the interpretation process were rare and 10 times more commonly categorized as learning opportunities not interfering with a clinically adequate report than as requiring patient callback. Further work is necessary to determine if creating learning opportunities leads to fewer patients requiring repeat examinations.

PURPOSE: Optimizing treatment strategies for patients with inflammatory breast cancer (IBC) relies on accurate initial staging. This study compared contrast-enhanced computed tomography (ce-CT) and FDG-PET/CT for initial staging of IBC to determine the frequency of discordance between the two imaging modalities and potential impact on management. METHODS: 81 patients with IBC underwent FDG-PET/CT and ce-CT prior to starting treatment. FDG-PET/CT and ce-CT scans were independently reviewed for locoregional and distant metastases and findings recorded by anatomic site as negative, equivocal, or positive for breast cancer involvement. Each paired ce-CT and FDG-PET/CT case was classified as concordant or discordant for findings. Discordant findings were subclassified as (a) related to the presence or absence of distant metastases; (b) affecting the locoregional radiation therapy plan; or (c) due to incidental findings not related to IBC. RESULTS: There were 47 discordant findings between ce-CT and FDG-PET/CT in 41 of 81 patients (50.6%). Thirty (63.8%) were related to the presence or absence of distant metastases; most commonly disease detection on FDG-PET/CT but not ce-CT (n = 12). FDG-PET/CT suggested alterations of the locoregional radiation therapy plan designed by CT alone in 15 patients. FDG-PET/CT correctly characterized 5 of 7 findings equivocal for metastatic IBC on ce-CT. CONCLUSIONS: This study demonstrates differences between ce-CT and FDG-PET/CT for initial staging of IBC and how these differences potentially affect patient management. Preliminary data suggest that FDG-PET/CT may be the imaging modality of choice for initial staging of IBC. Prospective trials testing initial staging with FDG-PET/CT versus important clinical end-points in IBC are warranted.

OBJECTIVE. The objective of this study was to assess impact of a report template quality improvement (QI) initiative on use of preferred phrases for communicating normal findings in structured abdominal CT and MRI reports. SUBJECTS AND METHODS. This prospective QI initiative, designed to decrease use of equivocal phrases and increase use of preferred and acceptable phrases (defined by multidisciplinary experts including patient advocates) in radiology reports, was performed in an academic medical center with over 800,000 annual radiologic examinations and was exempt from institutional review board approval. The intervention populated the preferred term "normal" (default) and acceptable specified pertinent negative phrases (pick-list option) when describing abdominal organ subheadings (liver, pancreas, spleen, adrenal glands, kidneys) within the "Findings" heading of abdominal CT and MRI report templates. We tabulated frequencies of the term "normal", specified pertinent negatives, and equivocal phrases in 21,629 reports before (June 1, 2017, to February 28, 2018) and 23,051 reports after (April 1, 2018, to December 31, 2018) the intervention using natural language processing and recorded trainee participation in report generation. We assessed intervention impact using statistical process control (SPC) charts and the Fisher exact test. RESULTS. Equivocal phrases were used less frequently in abdominal CT and MRI reports for both attending radiologists and trainees after the intervention (p < 0.05, SPC). Use of the term "normal" increased for reports generated by attending radiologists alone but decreased for reports created with trainee participation (p < 0.05, SPC). Frequency of pertinent negatives increased for reports with trainee participation (p < 0.05, SPC). CONCLUSION. A QI intervention decreased use of equivocal terms and increased use of preferred and acceptable phrases when communicating normal findings in abdominal CT and MRI reports.

PURPOSE: The aim of this study was to compare breast imaging subspecialists' follow-up recommendations for incidental liver lesions (ILLs) on breast MRI with abdominal subspecialty radiologists' opinions informed by best-practice recommendations. METHODS: In this retrospective study at an academic medical center, natural language processing identified reports with ILLs among 2,181 breast MRI studies completed in 2015. Electronic health record and radiology report reviews abstracted malignancy presence or absence, prior imaging, and breast subspecialists' recommendations regarding ILLs for random sets of 30 patients: ILLs with follow-up recommendations, ILLs without recommendations, and without ILLs. Two abdominal radiologists evaluated MRI liver findings and offered follow-up recommendations in consensus. The primary outcome was agreement between breast and abdominal subspecialists in patients with ILL follow-up recommendations compared with those without (χ2 analysis). Secondary outcomes were agreement between subspecialists when ILLs were reported and referring clinicians' adherence to follow-up recommendations. RESULTS: ILLs were identified in 11.3% of breast MRI reports (247 of 2,181); breast subspecialists made follow-up recommendations in 12% of them (30 of 247). Abdominal subspecialists agreed with breast subspecialists when ILLs required no follow-up (29 of 30 cases) but disagreed with 28 of 30 breast subspecialists' follow-up recommendations (agreement proportion 29 of 30 versus 2 of 30, P < .0001). Subspecialists agreed in 93% of cases (28 of 30) when breast imagers reported no ILLs. Overall, 16 of 30 breast subspecialists' follow-up recommendations were performed; ILLs were benign in 15. CONCLUSIONS: Abdominal subspecialists disagreed frequently with breast subspecialists regarding follow-up recommendations for ILLs on breast MRI. Abdominal subspecialty consultation or embedding liver imaging decision support in breast imaging reporting workflow may reduce unnecessary imaging and improve care. Improvement opportunities may exist in other cross-subspecialty interpretation workflows.

OBJECTIVE. Variability in reports of the same imaging study performed at the same institution may be confusing to referrers and patients, hindering results communication. The purpose of this study was to introduce a quality improvement initiative aimed at reducing variation in radiology report templates at a large academic center. MATERIALS AND METHODS. The quality improvement initiative was undertaken at a large multisite, multidivision academic radiology practice performing more than 820,000 radiologic examinations annually. A project charter defined the goals, scope, and personnel of the initiative and an escalation pathway for conflict resolution. Standard requirements for templates were initially developed. From September 2017 to May 2018, an oversight committee (24 organ system and modality-based work groups with representatives from nine subspecialty divisions) reviewed and harmonized all institutional radiology report templates across the enterprise irrespective of the imaging site or division that interpreted the study. The primary outcome measure was percentage reduction in report templates after harmonization. The secondary outcome measure was monthly adherence to harmonized templates for 9 months after implementation assessed by manual review of 40 randomly selected reports per month. The paired t test was used to assess template reduction, and the chi-square trend test was used to study trend in adherence to harmonized templates. RESULTS. Among 19,687 total templates at baseline, 597 harmonized templates remained after harmonization (p < 0.001). There was variation in template reduction by work group (multiple p < 0.05; reduction range, 79.2-99.3%). Radiologist adherence to harmonized templates ranged from 88.0% to 100%, unchanged in the 9 months after implementation (p = 0.23, chi-square trend). CONCLUSION. A radiology report harmonization initiative reduced 97.0% of report templates with a sustained high degree of adherence to harmonized templates after implementation at a large multisite multidivision academic radiology practice.

Indolent B cell lymphomas are a group of lymphoid malignancies characterized by their potential to undergo histologic transformation to aggressive lymphomas. While different subtypes of indolent B cell lymphomas demonstrate specific clinical and imaging features, histologic transformation can be suspected on cross-sectional imaging when disproportionate lymph node enlargement or new focal lesions in extranodal organs are seen. On PET/CT, transformed indolent lymphoma may show new or increased nodal FDG avidity or new FDG-avid lesions in different organs. In this article, we will (1) review the imaging features of different subtypes of indolent B cell lymphomas, (2) discuss the imaging features of histologic transformation, and (3) propose a diagnostic algorithm for transformed indolent lymphoma. The purpose of this review is to familiarize radiologists with the spectrum of clinical and imaging features of indolent B cell lymphomas and to define the role of imaging in raising concern for transformation and in guiding biopsy for confirmation.
RESUMO
BACKGROUND: The aim of this study was to determine if, in inflammatory breast cancer (IBC), baseline metabolic activity (maximum standardized uptake value [SUVmax]) of primary tumor and involved regional lymph nodes (IRLN) are prognostic markers of response after neoadjuvant systemic therapy (NAS). PATIENTS AND METHODS: Baseline 2-deoxy-2-[18F]fluoro-D-glucose (FDG) positron emission tomography/computed tomography scans were retrospectively reviewed among 61 women with IBC who received NAS, had mastectomy, and had available pathology reports. Primary tumor and IRLN SUVmax were compared between patients with a pathologic complete response (pCR) versus those with residual disease after NAS. A multivariate Cox model was fit to evaluate the effects of SUVmax on overall survival, adjusting for pCR and stratified by receptor status and disease stage. RESULTS: SUVmax in primary IBC tumors tended to increase with tumor grade (trend test P = .06) and was lower for stage III, non-triple-negative (TN) versus stage III, TN and stage IV, non-TN disease (P = .04). Neither primary tumor nor IRLN SUVmax was significantly different comparing pCR versus residual disease after NAS. Adjusting for pathology response in the overall survival model stratified by stage and receptor status, baseline SUVmax in primary IBC tumor was associated with an estimated hazard ratio of 1.10 (95% confidence interval, 0.97-1.25; P = .15) for patients with stage III, TN and stage IV, non-TN disease. This hazard ratio corresponded to a 1.74-fold risk of death with 1 standard deviation (SD = 5.9) increase in baseline SUVmax in primary IBC tumor. CONCLUSION: 2-deoxy-2-[18F]fluoro-D-glucose positron emission tomography/computed tomography provides prognostic information for newly diagnosed IBC. Larger studies are needed to confirm these findings and assess how such early information could affect treatment choices for IBC in the neoadjuvant setting.

OBJECTIVE: To retrospectively review the frequency, patterns and intra-abdominal sites of metastatic invasive lobular breast cancer, and to correlate the findings with overall survival. MATERIALS AND METHODS: From a pathology database search revealing 327 patients with metastatic lobular breast cancer at our institution from January 2004 through August 2014, imaging was available in 116 patients (age range, 31-87 years, mean age, 55). Simple descriptive statistics were performed to record and tabulate the abdominal metastatic spread. Prognostic significance of abdominal metastases and individual abdominal metastatic sites was studied using the Log-rank test and construction of Kaplan-Meier curves. RESULTS: The most frequent sites of intra-abdominal metastatic invasive lobular breast cancer were peritoneum (55 patients, 47%), followed by liver (37 patients, 32%), bowel (34 patients, 29%), ovary (33 patients, 28%), retroperitoneum (16 patients, 14%), ureter (16 patients, 14%), and lymph nodes (15 patients, 13%). Bowel obstruction was noted in 15 patients (13%) and hydronephrosis in 25 patients (22%). The median abdominal metastasis-free survival was 76 months (interquartile range: 17-191). The overall survival (OS) was 86 months (interquartile range: 49-188). Patients with abdominal metastases had shorter OS. Patients with hepatic metastases had shorter overall survival than those patients without hepatic metastases (p = 0.02, Log-Rank test). CONCLUSION: Invasive lobular breast cancer has a predilection for metastasizing to both typical (liver) and atypical intra-abdominal sites (peritoneum, GI tract, and adnexa). Presence of intra-abdominal disease and hepatic metastases in patients with ILC negatively affects overall survival.

OBJECTIVE: To evaluate the perception and ease of utilization of the imaging consultation service by different types of referring clinicians and physician extenders within the breast oncology disease center at our tertiary cancer institute using a survey-based questionnaire. METHODS: An institutional review board-exempted survey was created using a freely available online survey software and questionnaire tool. The survey was sent to 83 clinicians associated with the breast oncology disease center at our tertiary cancer center through an institutional e-mail list. The survey included 2 questions about demographics and 8 statements regarding various aspects of the consultation service scored on a 5-point Likert-type scale. "1'' being "agree completely," "3" being "neutral/neither agree nor disagree," and "5" being "disagree completely." The survey was sent online and was answered anonymously. Responses were tallied and analyzed. RESULTS: A total of 56 responses (67%) were received. The weighted average of each Likert item ranged from 1.07 to 1.58. Highest positive concordance (95%) pertained to the access to the consult radiologist having a positive impact on patient care. The least concordant statement (78%), though still strong (with weighted average of 1.58% and 78% of respondents agreeing or agreeing completely) pertained to the role of direct consultation with radiologist in clinical management. Although there was variability of agreement to all statements (including responders feeling neutral), there was no one that disagreed with any of the Likert items. The mean Likert score for all the statements together was 1.23 (range: 1.07-1.58). CONCLUSION: Presence of dedicated oncologic imaging consultation service is perceived positively by the breast oncology team at our tertiary cancer center.

PURPOSE: To reduce CT and MRI protocol variation across a multisite radiology practice at an academic medical center so that patients with similar clinical presentations are examined the same way. MATERIALS AND METHODS: This study was performed at a large academic radiology practice performing â¼800,000 radiology examinations annually. To diminish variability across the enterprise (2 general radiology divisions; 10 subspecialty imaging divisions), a Harmonization Oversight Committee was created and tasked with ensuring patients with similar clinical presentations undergo the same CT or MRI protocol, regardless of where they are imaged. A process for decision making and conflict resolution was established, supported by the department chair. Primary outcome measure was standardization of CT and MRI protocols across all sites. Secondary outcome was percent reduction of CT and MRI protocols postharmonization. RESULTS: Over the 5-month harmonization process, most conflicts arose for abdominal imaging protocols because they are performed in four distinct subspecialty divisions, but all were addressed effectively through the conflict resolution process. Overall, there was a 31% reduction in the total number of CT and MRI protocols (before harmonization 481, after harmonization 331). There was significant variation in reduction of protocols per workgroup (multiple P values; range <.0001 to .9) with largest reduction in workgroups that overlapped multiple divisions. CONCLUSION: A structured, organ system- and consensus-based quality improvement process with unambiguous decision-making and conflict resolution processes can be used to harmonize imaging protocols across complex, matrixed, multisite radiology practices so that patients with similar clinical presentations are imaged with the same imaging protocol.

PURPOSE OF REVIEW: Advanced mammographic imaging modalities have been implemented in clinical practices throughout the USA. The most notable and widely used has been the three-dimensional derivative of digital mammography, known as digital breast tomosynthesis (DBT). In this article, we review the screening and diagnostic applications of DBT, along with its limitations. We also briefly address several supplemental breast imaging modalities. RECENT FINDINGS: The accumulating evidence from both small and large-scale trials has shown a significant reduction in recall rates and slight increase in cancer detection rates when using DBT. However, the incremental increase in cancers detected remains less than that achieved with several supplemental imaging modalities, including whole-breast ultrasound, MRI, and MBI (molecular breast imaging). Other modalities, such as CEM (contrast-enhanced mammography) and CET (contrast-enhanced tomography), are also being investigated. Numerous studies have confirmed the added value of DBT and its increased cancer detection rate in both the screening and diagnostic settings. However, the superior sensitivity of supplemental imaging modalities renders them essential, especially in high-risk patients, and potentially those with dense breasts.

The purpose of the article is to describe the various radiology consultation models in the Era of Precision Medicine. Since the inception of our specialty, radiologists have served as consultants to physicians of various disciplines. A variety of radiology consultation services have been described in the literature, including clinical decision support, patient-centric, subspecialty interpretation, and/or some combination of these. In oncology care in particular, case complexity often merits open dialogue with clinical providers. To explore the utility and impact of radiology consultation services in the academic setting, this article will further describe existing consultation models and the circumstances that precipitated their development. The hybrid model successful at our tertiary cancer center is discussed. In addition, the contributions of a consultant radiologist in breast cancer care are reviewed as the archetype of radiology consultation services provided to oncology practitioners.

Diffuse large B cell lymphoma (DLBCL) is the most common histological subtype of Non-Hodgkin's lymphoma. As treatments continues to evolve, so do imaging strategies, and positron emission tomography (PET) has emerged as the most important imaging tool to guide oncologists in the diagnosis, staging, response assessment, relapse/recurrence detection,and therapeutic decision making of DLBCL. Other imaging modalities including magnetic resonance imaging (MRI), computed tomography (CT), ultrasound, and conventional radiography are also used in the evaluation of lymphoma. MRI is useful for nervous system and musculoskeletal system involvement and is emerging as a radiation free alternative to PET/CT. This article provides a comprehensive review of both the functional and morphological imaging modalities, available in the management of DLBCL.
