A Practical Guide for Paid Family and Medical Leave in Radiology, From the AJR Special Series on DEI.

Paid family and medical leave (FML) has significant benefits to organizations, including improvements in employee recruitment and retention, workplace culture, and employee morale and productivity, and is supported by evidence for overall cost savings. Furthermore, paid FML related to childbirth has significant benefits to individuals and families, including but not limited to improved maternal and infant health outcomes and improved breastfeeding initiation and duration. In the case of nonchildbearing parental leave, paid FML is associated with more equitable long-term division of household labor and childcare. Paid FML is increasingly being recognized as an important issue in medicine, as evidenced by the recent passage of policies by national societies and governing bodies, including the American Board of Medical Specialties, American Board of Radiology, Accreditation Council for Graduate Medical Education (ACGME), American College of Radiology, and American Medical Association. Implementation of paid FML requires adherence to federal, state, and local laws as well as institutional requirements. Specific requirements pertain to trainees from national governing bodies, such as the ACGME and medical specialty boards. Flexibility, work coverage, culture, and finances are additional considerations for ensuring an optimal paid FML policy that accounts for concerns of all impacted individuals.

Disruptive Behavior: Impact on Diversity, Equity, and Inclusion (DEI) in Radiology, From the AJR Special Series on DEI.

Radiology has recognized the need to increase the diversity of its workforce for decades; however, women and people of color remain disproportionately underrepresented. A welcoming and inclusive environment is essential to physician recruitment and retention, but disruptive behavior in the workplace can be a barrier to achieving this goal. Disruptive behavior can be overt or subtle, can be intentional or inadvertent, and can occur in different settings throughout a radiologist's career, including during patient care, among colleagues, from department leadership, and even from professional societies. The purpose of this article is to provide an overview of where a radiologist may encounter disruptive behaviors, the impact that such behaviors can have on the physician's and practice's well-being, and tips for how to address and mitigate these behaviors in the future.

A Common Path: Magnetic Resonance Imaging of Müllerian and Wolffian Duct Anomalies.

PURPOSE OF REVIEW: This review summarizes the pathway of Mullerian and Wolffian duct development, anomalies that result from disruptions to this pathway, and the characteristics on advanced imaging that identify them. RECENT FINDINGS: In-office evaluation for reproductive anomalies is usually inadequate for the diagnosis of congenital reproductive anomalies. Magnetic resonance imaging (MRI) has usurped invasive diagnostic methods including laparoscopy, hysteroscopy, and vasography as the new gold standard. Because of its superior soft-tissue delineation and the availability of advanced functional sequences, MRI offers a sophisticated method of distinguishing reproductive anomalies from one another, characterizing the degree of defect severity, and evaluating for concomitant urogenital anomalies non-invasively and without radiation exposure to the patient. Congenital anomalies of the Mullerian and Wolffian duct can be incredibly nuanced, requiring prompt and accurate diagnosis for management of infertility. Definitive diagnosis should be made early with MRI.

Multimodality Multisystem Imaging of Pregnancy-Related Changes: Featuring Neurologic, Cardiothoracic, Breast, Gynecologic, and Musculoskeletal Issues.

ABSTRACT: Pregnancy and the puerperium are a time of significant physiologic change, and with an average of 4 million births in the United States yearly, radiologists encounter pregnancy-related imaging findings regularly. While many of these findings represent physiologic changes, a significant number represent pathology, making it paramount for radiologists to distinguish between the two. This case-based article reviews imaging findings within the nervous, cardiovascular, pulmonary, breast, gynecologic, musculoskeletal, digestive, hematologic, and integumentary systems throughout pregnancy and the postpartum period.

Establishing a Women-in-Radiology Group: A Toolkit From the American Association for Women in Radiology.

Despite increasing representation in medical schools and surgical specialties, recruitment of women into radiology has failed to exhibit commensurate growth. Furthermore, women are less likely than men to advance to leadership roles in radiology. A women-in-radiology (WIR) group provides a robust support system that has been shown to produce numerous benefits to the group's individual participants as well as the group's institution or practice. These benefits include development of mentor-ship relationships, guidance of career trajectories, improved camaraderie, increased participation in scholarly projects, and increased awareness of gender-specific issues. This article describes a recommended pathway to establishing a WIR group, with the goal of fostering sponsorship and promoting leadership, recruitment, and advancement of women in radiology. We consider barriers to implementation and review resources to facilitate success, including a range of resources provided by the American Association for Women in Radiology. By implementing the provided framework, radiologists at any career stage can start a WIR group, to promote the advancement of their female colleagues.

Utility of 18F-Fluciclovine PET/MRI for Staging Newly Diagnosed High-Risk Prostate Cancer and Evaluating Response to Initial Androgen Deprivation Therapy: A Prospective Single-Arm Pilot Study.

BACKGROUND. Despite advances in prostate cancer treatment, rates of biochemical recurrence remain high, relating to lack of detection of small-volume metastatic disease using conventional imaging for initial staging. OBJECTIVE. The purpose of this study was to assess the potential use of 18F-fluciclovine PET/MRI for initial staging of high-risk prostate cancer and evaluating response to androgen deprivation therapy (ADT). METHODS. This prospective clinical trial enrolled 14 men with newly diagnosed high-risk prostate cancer and negative or equivocal conventional staging imaging for metastatic disease between January 2018 and February 2019. All patients underwent pretreatment 18F-fluciclovine PET/MRI including multiparametric prostate MRI; 12 underwent 18F-fluciclovine PET/MRI after surgery or between ADT and radiotherapy. Confidence in identification of the primary intraprostatic lesion and nodal metastases was independently rated on a 0-3 Likert scale by three readers with nuclear medicine experience for 18F-fluciclovine PET/MRI and three readers with abdominal imaging experience for MRI alone. Findings scored as 2 or 3 by at least two readers of a given modality were considered positive. A single reader measured SUVmean, SUVmax, and volume of the MRI-defined intraprostatic lesion and SUVmax of suspicious lymph nodes on PET before and after initiation of ADT. Changes in SUV were analyzed using nonparametric Wilcox-on signed-rank tests. RESULTS. The biopsy-proven lesion in the prostate gland was accurately identified in all 14 patients on both MRI and 18F-fluciclovine PET/MRI. Suspected nodal metastases were detected in three patients on MRI and seven patients on 18F-fluciclovine PET/MRI. After ADT, all patients showed decreased activity within the intraprostatic lesion and/or all suspicious lymph nodes. The primary lesion SUVmean was 4.5 ± 1.1 (range, 2.7-6.5) before treatment and 2.4 ± 1.1 (range, 0.0-3.6) after initiation of ADT (p = .008). For suspicious lymph nodes, the pretreatment SUVmax was 5.5 ± 3.7 (range, 2.8-12.7) and the post-treatment SUVmax was 2.8 ± 1.4 (range, 1.4-5.5) (p = .03). CONCLUSION.18F-labeled fluciclovine PET/MRI shows potential utility in initial staging of high-risk prostate cancer and in evaluating response to ADT. CLINICAL IMPACT. Given the FDA approval and widespread availability of 18F-fluciclovine, the findings could have an impact in the immediate future in guiding initial management of patients with prostate cancer.

Applications of PET/MRI in Abdominopelvic Oncology.

With PET/MRI, the strengths of PET and MRI are combined to allow simultaneous image acquisition and near-perfect image coregistration. MRI is increasingly being used for staging and restaging of abdominopelvic oncologic lesions, including prostate, hepatobiliary, pancreatic, neuroendocrine, cervical, and rectal cancers. Fluorine 18-fluorodeoxyglucose PET/CT has long been considered a cornerstone of oncologic imaging, and the development of multiple targeted radiotracers has led to increased research on and use of these agents in clinical practice. Thus, simultaneously performed PET/MRI enables the acquisition of complementary imaging information, with distinct advantages over PET/CT and MR image acquisitions. The authors provide an overview of PET/MRI, including descriptions of the major differences between PET/MRI and PET/CT, as well as case examples and treatment protocols for patients with commonly encountered malignancies in the abdomen and pelvis.

Stereotactic body radiation therapy with simultaneous integrated boost for prostate cancer: does MRI-targeted biopsy alter the boost field?

INTRODUCTION: We aim to investigate if the addition of MRI-US fusion biopsy (FB) can aid in radiation planning and alter the boost field in cases of stereotactic body radiation therapy (SBRT) for prostate cancer with a simultaneous integrated boost (SIB) to a magnetic resonance imaging (MRI)-defined intraprostatic lesion. MATERIALS AND METHODS: Patients undergoing SBRT with SIB for biopsy-proven prostatic adenocarcinoma and a pre-radiation MRI were retrospectively reviewed. 36.25 Gy in 5 fractions was delivered to entire prostate along with SIB of 40 Gy to an MRI-defined intraprostatic lesion. Demographic, radiation planning details, and post-procedural outcomes were compared between patients undergoing systematic transrectal ultrasound (TRUS) biopsy followed by MRI to those undergoing an MRI followed by a FB prior to radiation planning. RESULTS: Forty-three patients underwent systematic TRUS biopsy followed by MRI and 46 patients underwent FB prior to radiation planning. Patients undergoing systematic TRUS biopsy had a smaller prostate volume when compared to the FB cohort (37.58 ± 13.78 versus 50.28 ± 26.76 cc, p = 0.007). No differences in prostate planning target volume (PTVprostate) and boost volume (PTVboost) were noted, but those undergoing TRUS biopsy prior to MRI had a higher integrated boost volume density (IBVD = PTVboost/total prostate volume) (0.16 ± 0.09 versus 0.13 ± 0.06, p = 0.045). No differences were observed in genitourinary or gastrointestinal toxicity rates. CONCLUSIONS: Compared to systematic TRUS biopsy, implementation of prebiopsy prostate MRI and FB allows for safe and feasible SBRT in patients with significantly larger prostate volumes without increasing SIB cancer-directed treatment volumes, oncologic outcomes, quality of life measures, or treatment-related toxicities.

How Fast Can We Go: Abbreviated Prostate MR Protocols.

PURPOSE OF REVIEW: Multiparametric MRI (mpMRI), composed of T2WI, DWI, and DCE sequences, is effective in identifying prostate cancer (PCa), but length and cost preclude its application as a PCa screening tool. Here we review abbreviated MRI protocols that shorten or omit conventional mpMRI components to reduce scan time and expense without forgoing diagnostic accuracy. RECENT FINDINGS: The DCE sequence, which plays a limited diagnostic role in PI-RADS, is eliminated in variations of the biparametric MRI (bpMRI). T2WI, the lengthiest sequence, is truncated by only acquiring the axial plane or utilizing 3D acquisition with subsequent 2D reconstruction. DW-EPISMS further accelerates DWI acquisition. The fastest protocol described to date consists of just DW-EPISMS and axial-only 2D T2WI and runs less than 5 min. Abbreviated protocols can mitigate scan expense and increase scan access, allowing prostate MRI to become an efficient PCa screening tool.

Current Imaging Techniques for Noninvasive Staging of Hepatic Fibrosis.

OBJECTIVE. The purpose of this article is to discuss quantitative methods of CT, MRI, and ultrasound (US) for noninvasive staging of hepatic fibrosis. Hepatic fibrosis is the hallmark of chronic liver disease (CLD), and staging by random liver biopsy is invasive and prone to sampling errors and subjectivity. Several noninvasive quantitative imaging methods are under development or in clinical use. The accuracy, precision, technical aspects, advantages, and disadvantages of each method are discussed. CONCLUSION. The most promising methods are the liver surface nodularity score using CT and measurement of liver stiffness using MR elastography or US elastography.

Advanced Imaging in Female Infertility.

PURPOSE OF REVIEW: This review highlights the role of imaging in the diagnosis and management of reproductive disorders. The additional information that imaging studies can contribute to reproductive medicine is emphasized, including the role of pelvic ultrasonography (US, including sonohysterography and contrast-enhanced hysterosalpingosonography), hysterosalpingography (HSG), and magnetic resonance imaging (MRI) of the female reproductive tract. In addition, the implications of congenital causes of infertility on the urinary tract in females are reviewed. While the evaluation of infertility in women is initially focused on the assessment of ovulation via serum hormone levels, imaging plays a role in evaluating other causes of infertility. Recent research in this field focuses on the establishment of a comprehensive single imaging study for the assessment of female reproductive disorders. Two proposed methods are MR hysterosalpingography and Fertiliscan, a combination of high-quality 3D ultrasound and assessment of tubal patency with hysterosalpingo-foam-sonography, though more research is needed to determine the risks and benefits of each method, as well as their reliability.

The role of transesophageal echocardiography in the management of renal cell carcinoma with venous tumor thrombus.

We reviewed the role of transesophageal echocardiography (TEE) in the management of renal cell carcinoma (RCC) with associated tumor thrombus. Many consider intraoperative TEE as imperative in cases of Level 4 thrombi with atrial involvement, as well as in cases that require the use of cardiopulmonary bypass (CPB). However, the role of TEE in the surgical management of RCC with associated inferior vena cava (IVC) thrombus may expand beyond this subset. When performed after induction, TEE provides updated information regarding tumor thrombus staging, which is essential for optimal surgical planning. Furthermore, TEE provides feedback regarding properties of the thrombus, such as fragility and adherence, which may alter surgical technique. TEE can also be used intraoperatively for central venous line placement, to monitor cardiovascular and fluid status, to guide vascular clamp placement, and to ensure complete removal of the tumor thrombus. In some cases, the use of TEE allows for less morbid procedures and safe avoidance of CPB. We therefore recommend the use of preoperative TEE in all cases with a known tumor thrombus with discretion as to what extent TEE is used throughout the remainder of the case. Further investigation is necessary to elucidate the effect of TEE on patient outcomes, including surgical complication rates, morbidity and mortality of procedures, and cancer control.

Evaluation of Left Ventricular Outflow Tract Obstruction With Four-Dimensional Phase Contrast Magnetic Resonance Imaging in Patients with Hypertrophic Cardiomyopathy-A Pilot Study.

OBJECTIVE: This study aimed to validate 4-dimensional phase contrast (4D PC) cine magnetic resonance imaging (MRI) as a means of evaluating left ventricular outflow tract (LVOT) obstruction in patients with hypertrophic cardiomyopathy (HCM). METHODS: In this institutional review board-approved prospective study, 23 patients with suspected HCM from October 2012 to September 2013 underwent 4D PC MRI. Postprocessed 4D PC pathline cine data were reviewed by 2 blinded reviewers to determine presence or absence of LVOT obstruction. Sensitivity, specificity, and accuracy in 4D PC qualitative and quantitative assessment of LVOT obstruction were calculated using echo as reference standard. RESULTS: Consensus interpretation of 4D PC showed 100.0% (7/7) sensitivity, 75.0% specificity (12/16), and 82.6% (19/23) accuracy in assessment of LVOT obstruction. The 4D PC quantitative estimates of LVOT gradient have 71.4% (5/7) sensitivity, 93.8% (15/16) specificity, and 87.0% (20/23) accuracy in evaluation of LVOT obstruction compared with echo. CONCLUSIONS: The 4D PC MRI can assess for LVOT obstruction in HCM patients.

ACR Appropriateness Criteria® Sepsis.

Sepsis is defined as a life-threatening organ dysfunction caused by a dysregulated host response to infection. A search for the underlying cause of infection typically includes radiological imaging as part of this investigation. This document focuses on thoracic and abdominopelvic causes of sepsis. In 2017, the global incidence of sepsis was estimated to be 48.9 million cases, with 11 million sepsis-related deaths (accounting for nearly 20% of all global deaths); therefore, understanding which imaging modalities and types of studies are acceptable or not acceptable is imperative. The 5 variants provided include the most commonly encountered scenarios in the setting of sepsis along with recommendations and data for each imaging study. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where peer reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

American College of Radiology Paid Family/Medical Leave Policy: A Call to Action for the House of Medicine.

The American College of Radiology (ACR) passed a historic paid family/medical leave (PFML) resolution at its April 2022 meeting, resolving that "diagnostic radiology, interventional radiology, radiation oncology, medical physics, and nuclear medicine practices, departments and training programs strive to provide 12 weeks of paid family/medical leave in a 12-month period for its attending physicians, medical physicists, and members in training as needed." The purpose of this article is to share this policy beyond radiology so that it may serve as a call to action for other medical specialties. Such a PFML policy (1) supports physician well-being, which in turn supports patient care; (2) is widely needed across American medical specialties; and (3) should not take nearly a decade to achieve, as it did in radiology, especially given increasing physician burnout and the ongoing COVID-19 pandemic. Supported by information on the step-by-step approach used to achieve radiology-specific leave policies and considering current and normative policies at the national level, this article concludes by reviewing specific strategies that could be applied toward achieving a 12-week PFML policy for all medical specialties.

Quantifying 4D flow cardiovascular magnetic resonance vortices in patients with pulmonary hypertension: A pilot study.

In this 4D flow cardiovascular magnetic resonance (CMR) study, vortical blood flow in the main pulmonary artery (MPA) is quantified using circulation (á´¦), a metric used in fluid dynamics to quantify the rotational components of flow. Circulation (á´¦) is a 4D flow CMR metric that quantifies the vortical blood flow pattern in the MPA of patients with pulmonary hypertension (PH), distinguishes them from healthy controls, and shows high correlation with invasive markers of PH severity.

ACR Appropriateness Criteria® Right Upper Quadrant Pain: 2022 Update.

Acute right upper quadrant pain is one of the most common presenting symptoms in hospital emergency departments, as well as outpatient settings. Although gallstone-related acute cholecystitis is a leading consideration in diagnosis, a myriad of extrabiliary sources including hepatic, pancreatic, gastroduodenal, and musculoskeletal should also be considered. This document focuses on the diagnostic accuracy of imaging studies performed specifically to evaluate acute right upper quadrant pain, with biliary etiologies including acute cholecystitis and its complications being the most common. An additional consideration of extrabiliary sources such as acute pancreatitis, peptic ulcer disease, ascending cholangitis, liver abscess, hepatitis, and painful liver neoplasms remain a diagnostic consideration in the right clinical setting. The use of radiographs, ultrasound, nuclear medicine, CT, and MRI for these indications are discussed. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.
