Contrasting pediatric specialty provider opinion between contextualized and structured radiology reports.

BACKGROUND: Structured reporting (SR) replaced narrative (free text) reporting and utilizes templated headings and subheadings with findings typically based on the anatomy included in the examination. Its use has been widely advocated by radiology and non-radiology organizations as the new reporting standard. There are, however, shortcomings to SR, such as templated text not addressing a specific clinical indication. Contextual reporting (CR) fills this gap. CR is a type of SR which is tailored to a narrow clinical indication by including pertinent positive and negative findings for that specific clinical entity. OBJECTIVE: This study assesses provider preferences for CR as compared to SR in the pediatric practice environment using a survey methodology. METHODS & MATERIALS: Surveys with examples of SR and CR reports were sent electronically to two groups. One group was focused on neurological diseases and included pediatric specialists in neurosurgery, neurology, ENT, ED, and ophthalmology (190 people), referred to as the pediatric neuroimaging group. The pediatric neuroimaging group survey contained examples of CR and SR reports of an orbital CT for orbital cellulitis and a head CT for stroke. The other group was focused on gastrointestinal diseases, and included pediatric specialists in gastroenterology, general surgery, and the ED (159 people), referred to as the pediatric gastrointestinal (GI) imaging group. The pediatric GI imaging group survey contained example reports of an abdominal CT for appendicitis and an MRI enterography for Crohn's disease. Surveys utilizing a 5-point Likert scale were analyzed via Fischer's exact test with a p-value deemed statistically significant at less than 0.05. RESULTS: 349 individuals were contacted to participate in the survey. There were 81 (23 %, 81/349) survey respondents; 41 (22 %, 41/190) from the neuro group, and 40 (25 %, 40/159) from the GI group. 56 % (45/81) of all respondents preferred CR reports over traditional SR reports, while 29 % (23/81) did not. Most respondents (59 %, 48/81) indicated that CR reports are easier to interpret than traditional SR reports. Respondents from the pediatric neuroimaging group favored CR reports to a lesser degree (44 %, 36/81) compared to respondents from the pediatric GI imaging group (68 %, 55/81). CONCLUSIONS: We learned from this survey that it would be beneficial to be very intentional about selecting clinical indications where CR would be most valued rather than trying to develop CR for any specific clinical indication. The study results indicate it is reasonable to continue further efforts at exploring the utility of contextualized reports.

ResearchConnect.info: An Interactive Web-Based Platform for Building Academic Collaborations.

RATIONALE AND OBJECTIVES: Radiology is a rapidly evolving field that benefits from continuous innovation and research participation among trainees. Traditional methods for involving residents in research are often inefficient and limited, usually due to the absence of a standardized approach to identifying available research projects. A centralized online platform can enhance networking and offer equal opportunities for all residents. MATERIALS AND METHODS: Research Connect is an online platform built with PHP, SQL, and JavaScript. Features include project and collaboration listing as well as advertisement of project openings to medical/undergraduate students, residents, and fellows. The automated system maintains project data and sends notifications for new research opportunities when they meet user preference criteria. Both pre- and post-launch surveys were used to assess the platform's efficacy. RESULTS: Before the introduction of Research Connect, 69% of respondents used informal conversations as their primary method of discovering research opportunities. One year after its launch, Research Connect had 141 active users, comprising 63 residents and 41 faculty members, along with 85 projects encompassing various radiology subspecialties. The platform received a median satisfaction rating of 4 on a 1-5 scale, with 54% of users successfully locating projects of interest through the platform. CONCLUSION: Research Connect addresses the need for a standardized method and centralized platform with active research projects and is designed for scalability. Feedback suggests it has increased the visibility and accessibility of radiology research, promoting greater trainee involvement and academic collaboration.

Patient Engagement in Neuroradiology: A Narrative Review and Case Studies.

The field of patient engagement in radiology is evolving and offers ample opportunities for neuroradiologists to become involved. The patient journey can serve as a model that inspires patient engagement initiatives. The patient journey in radiology may be viewed in 5 stages: 1) awareness that an imaging test is needed, 2) considering having a specific imaging test, 3) access to imaging, 4) imaging service delivery, and 5) ongoing care. Here, we describe patient engagement opportunities based on literature review and paired with case studies by practicing neuroradiologists.

Indoximod-based chemo-immunotherapy for pediatric brain tumors: A first-in-children phase I trial.

BACKGROUND: Recurrent brain tumors are the leading cause of cancer death in children. Indoleamine 2,3-dioxygenase (IDO) is a targetable metabolic checkpoint that, in preclinical models, inhibits anti-tumor immunity following chemotherapy. METHODS: We conducted a phase I trial (NCT02502708) of the oral IDO-pathway inhibitor indoximod in children with recurrent brain tumors or newly diagnosed diffuse intrinsic pontine glioma (DIPG). Separate dose-finding arms were performed for indoximod in combination with oral temozolomide (200 mg/m2/day x 5 days in 28-day cycles), or with palliative conformal radiation. Blood samples were collected at baseline and monthly for single-cell RNA-sequencing with paired single-cell T cell receptor sequencing. RESULTS: Eighty-one patients were treated with indoximod-based combination therapy. Median follow-up was 52 months (range 39-77 months). Maximum tolerated dose was not reached, and the pediatric dose of indoximod was determined as 19.2 mg/kg/dose, twice daily. Median overall survival was 13.3 months (n = 68, range 0.2-62.7) for all patients with recurrent disease and 14.4 months (n = 13, range 4.7-29.7) for DIPG. The subset of n = 26 patients who showed evidence of objective response (even a partial or mixed response) had over 3-fold longer median OS (25.2 months, range 5.4-61.9, p = 0.006) compared to n = 37 nonresponders (7.3 months, range 0.2-62.7). Four patients remain free of active disease longer than 36 months. Single-cell sequencing confirmed emergence of new circulating CD8 T cell clonotypes with late effector phenotype. CONCLUSIONS: Indoximod was well tolerated and could be safely combined with chemotherapy and radiation. Encouraging preliminary evidence of efficacy supports advancing to Phase II/III trials for pediatric brain tumors.

Medical Malpractice and Diagnostic Radiology: Challenges and Opportunities.

Medicolegal challenges in radiology are broad and impact both radiologists and patients. Radiologists may be affected directly by malpractice litigation or indirectly due to defensive imaging ordering practices. Patients also could be harmed physically, emotionally, or financially by unnecessary tests or procedures. As technology advances, the incorporation of artificial intelligence into medicine will bring with it new medicolegal challenges and opportunities. This article reviews the current and emerging direct and indirect effects of medical malpractice on radiologists and summarizes evidence-based solutions.

Magnetic Resonance Imaging Findings and Genetic Testing Results in Children With Congenital Corneal Opacities.

PURPOSE: This study investigates brain and globe abnormalities identified on magnetic resonance imaging (MRI) in children with congenital corneal opacities (CCO). DESIGN: Retrospective cohort study. METHODS: Clinical notes, radiology records, and genetic testing results were reviewed for patients diagnosed with corneal opacification within the first 6 months of life at a tertiary referral academic center between August 2008 and January 2018. Ocular findings, systemic anomalies, neuroimaging, and genetic testing results were summarized. RESULTS: A total of 135 patients presenting at age 1 day to 12 years (mean age, 1 year) were identified. Children with bilateral CCO were more likely to have systemic disease (P = 0.018). Of the entire cohort, 43 (31.8%) patients received MRI, of whom 27 (62.8%) had abnormal brain findings and 30 (69.7%) had abnormal orbital findings. The most common abnormal brain findings were ventriculomegaly (n = 16, 59.2%) and corpus callosum abnormalities (n = 10, 37.0%) followed by brainstem/pons anomalies (n = 5, 18.5%), and cerebellar anomalies (n = 2, 7.4%). Abnormal brain MRI findings were associated with the presence of neurologic (P = .003) and craniofacial (P = .034) disease. A total of 44 (32.1%) patients underwent genetic testing, of whom 29 (65.9%) had pathogenic results. CONCLUSIONS: More than 60% of the children with CCO who underwent MRI had abnormal brain and orbit findings that were correlated with significant neurologic disease. Furthermore, almost two-thirds of patients with CCO who underwent genetic testing had pathogenic results. These data demonstrate the value of systemic workup in children with CCO, and highlight the role of ophthalmologists in facilitating the diagnosis of systemic comorbidities associated with CCO.

Patient-Centered Radiology Communications: Engaging Patients as Partners.

Patient-centered care is a model in which, by bringing the patient's perspective to the design and delivery of health care, we can better meet patients' needs, enhancing the quality of care. Patient-centered care requires finding ways to communicate effectively with a diverse patient population that has various levels of health literacy, cultural backgrounds, and unique needs and preferences. Moreover, multimedia resources have the potential to inform and educate patients promoting greater independence. In this review, we discuss the fundamentals of communication with the different modes used in radiology and the key elements of effective communication. Then, we highlight five opportunities along the continuum of care in the radiology practice in which we can improve communications to empower our patients and families and strengthen this partnership. Lastly, we discuss the importance on communication training of the workforce, optimizing and seamlessly integrating technology solutions into our workflows, and the need for patient feedback in the design and delivery of care.

Impact of Early Direct Patient Notification on Follow-Up Completion for Nonurgent Actionable Incidental Radiologic Findings.

PURPOSE: The aim of this study was to evaluate whether early direct patient notification in addition to an existing multistage recommendation-tracking system (Backstop) increases follow-up completion rates for actionable incidental findings (AIFs). Patient attitudes toward early notification were also assessed. METHODS: This prospective, randomized controlled trial recruited patients with AIFs requiring follow-up being enrolled into the Backstop system. Patients were randomized into four groups: those receiving additional early direct notification in a mailed letter (group 1, similar to Pennsylvania Act 112), by phone (group 2), or in an electronic portal message (group 3) and a control group (group 4) without additional notifications added to the existing Backstop system. Differences in follow-up completion rates among these groups were determined using χ2 tests. Patients were surveyed on binary yes/no and Likert-type scale questions, and descriptive statistics are reported. RESULTS: Data from 2,548 randomized patients were analyzed for the study, including 593 patients notified by letter, 637 notified by phone, 701 notified by portal, and 617 control patients. Group 3 demonstrated the lowest rate of follow-up completion within 1 month of the follow-up due date at 36.4%, compared with 58.7% for group 1, 60.4% for group 2, and 53.2% for group 4 (P < .0001 for all). Group 2 was the only group to have a significantly higher completion rate than group 4 (P = .014). Patients responded positively regarding early notification and preferred electronic portal communication. CONCLUSIONS: Early direct notification had a mixed impact on follow-up completion rates on the basis of communication modality but was positively received by patients and may have health care benefits when implemented within a recommendation-tracking system.

Diagnostic Excellence in Pediatric Spine Imaging: Using Contextualized Imaging Protocols.

Contextual design and selection of MRI protocols is critical for making an accurate diagnosis given the wide variety of clinical indications for spine imaging in children. Here, we describe our pediatric spine imaging protocols in detail, tailored to specific clinical questions.

Early in vivo Radiation Damage Quantification for Pediatric Craniospinal Irradiation Using Longitudinal MRI for Intensity Modulated Proton Therapy.

Purpose: Proton vertebral body sparing craniospinal irradiation (CSI) treats the thecal sac while avoiding the anterior vertebral bodies in an effort to reduce myelosuppression and growth inhibition. However, robust treatment planning needs to compensate for proton range uncertainty, which contributes unwanted doses within the vertebral bodies. This work aimed to develop an early in vivo radiation damage quantification method using longitudinal magnetic resonance (MR) scans to quantify the dose effect during fractionated CSI. Methods and Materials: Ten pediatric patients were enrolled in a prospective clinical trial of proton vertebral body sparing CSI, in which they received 23.4 to 36 Gy. Monte Carlo robust planning was used, with spinal clinical target volumes defined as the thecal sac and neural foramina. T1/T2-weighted MR scans were acquired before, during, and after treatments to detect a transition from hematopoietic to less metabolically active fatty marrow. MR signal intensity histograms at each time point were analyzed and fitted by multi-Gaussian models to quantify radiation damage. Results: Fatty marrow filtration was observed in MR images as early as the fifth fraction of treatment. Maximum radiation-induced marrow damage occurred 40 to 50 days from the treatment start, followed by marrow regeneration. The mean damage ratios were 0.23, 0.41, 0.59, and 0.54, corresponding to 10, 20, 40, and 60 days from the treatment start. Conclusions: We demonstrated a noninvasive method for identifying early vertebral marrow damage based on radiation-induced fatty marrow replacement. The proposed method can be potentially used to quantify the quality of CSI vertebral sparing and preserve metabolically active hematopoietic bone marrow.

Single Ventricle Reconstruction III: Brain Connectome and Neurodevelopmental Outcomes: Design, Recruitment, and Technical Challenges of a Multicenter, Observational Neuroimaging Study.

Patients with hypoplastic left heart syndrome who have been palliated with the Fontan procedure are at risk for adverse neurodevelopmental outcomes, lower quality of life, and reduced employability. We describe the methods (including quality assurance and quality control protocols) and challenges of a multi-center observational ancillary study, SVRIII (Single Ventricle Reconstruction Trial) Brain Connectome. Our original goal was to obtain advanced neuroimaging (Diffusion Tensor Imaging and Resting-BOLD) in 140 SVR III participants and 100 healthy controls for brain connectome analyses. Linear regression and mediation statistical methods will be used to analyze associations of brain connectome measures with neurocognitive measures and clinical risk factors. Initial recruitment challenges occurred related to difficulties with: 1) coordinating brain MRI for participants already undergoing extensive testing in the parent study, and 2) recruiting healthy control subjects. The COVID-19 pandemic negatively affected enrollment late in the study. Enrollment challenges were addressed by 1) adding additional study sites, 2) increasing the frequency of meetings with site coordinators and 3) developing additional healthy control recruitment strategies, including using research registries and advertising the study to community-based groups. Technical challenges that emerged early in the study were related to the acquisition, harmonization, and transfer of neuroimages. These hurdles were successfully overcome with protocol modifications and frequent site visits that involved human and synthetic phantoms. Trial registration number: ClinicalTrials.gov Registration Number: NCT02692443.

Imaging of pediatric spine and spinal cord tumors: A COG Diagnostic Imaging Committee/SPR Oncology Committee/ASPNR White Paper.

Childhood spinal tumors are rare. Tumors can involve the spinal cord, the meninges, bony spine, and the paraspinal tissue. Optimized imaging should be utilized to evaluate tumors arising from specific spinal compartments. This paper provides consensus-based recommendations for optimized imaging of tumors arising from specific spinal compartments at diagnosis, follow-up during and after therapy, and response assessment.

Skull Fracture Healing in Children Up to 36 Months - A Cohort Analysis.

During medicolegal proceedings in cases of suspected child abuse it is sometimes argued that skull fractures could be sequelae from complications at birth or resulted from a prior witnessed accidental trauma that may have preceded the suspected abusive event. There is paucity of scientific evidence indicating timing for skull fracture healing in children up to 36 months old. Objective of this study was to assess the average time to imaging documentation of skull fracture healing in children up to 36 months old. We performed retrospective chart review and image analysis in children with documented skull fractures after trauma between May 2009 and December 2014, excluding any patients who underwent cranial procedures related to the head injury, patients with pre-existing CSF shunts, patients who were referred for child abuse evaluation, and patients who were admitted to the General Surgery service for multi-organ trauma.We analyzed 185 skull fractures: 82 fractures were not healed, 49 fractures were partially healed, and 54 fractures were healed on follow-up imaging. The mean time to imaging evidence of healing among patients with healed fractures was 108 days (3.6 months), the median was 112 days (3.7 months), the minimum was 22 days, and the maximum was 225 days (7.5 months). Chi-square analysis showed a significant relationship between the skull fracture healed status and presence of bleed (P = 0.001) and with fracture characteristics of displaced, depressed, or dehiscent (P= 0.009). There was no significant association with the age group (P= 0.32) nor with involvement of multiple cranial plates (P= 0.73). This information may be useful during medicolegal proceedings in patients with suspected abusive head trauma mechanism.
