Objective: First, to determine the frequency and spectrum of osteoid osteoma (OO)-mimicking lesions among presumed OO referred for radiofrequency ablation (RFA). Second, to compare patient sex and age, lesion location, and rates of primary treatment failure for OO based on histopathology results.
Materials And Methods: A retrospective review was performed of all first-time combined CT-guided biopsy/RFA for presumed OO at a single academic center between January 1990 and August 2023.

Objective: To evaluate clinical and radiological features of extraskeletal myxoid chondrosarcomas (EMC).
Material And Methods: Our pathology database was queried for cases of EMCs. Tumor location, size, imaging appearance, presence of metastases, disease recurrence, and clinical outcome were documented.
Objective: To compare the frequency of elongated morphology of osteoid osteoma (OO) in children compared to adolescents and to determine if this elongated morphology is associated with radiofrequency ablation treatment failure.
Materials And Methods: Retrospective review of first-time CT-guided radiofrequency ablation performed for presumed OO in patients < 21 years old between 1990 and 2023. Children were considered 0 to 10 years old, and adolescents were considered 11 to 20 years old.
Rationale And Objectives: Medical education led by peers and near-peers has been shown to benefit both teachers and learners and can be successfully incorporated into radiology education. The authors created a virtual, multi-institution pediatric radiology conference employing peer and near-peer teaching with the goals of improving radiology knowledge and enhancing the educational experience of radiology trainees.
Materials And Methods: Two radiology residency programs implemented a common pediatric radiology curriculum and joint quarterly virtual peer teaching conference.

Learning objectives are invaluable components of medical curricula. They are required by the ACGME for all educational experiences offered by radiology residencies, but their number and quality varies significantly from program to program. In this article, we describe the development of a new pediatric radiology curriculum featuring outcome-based learning objectives with accompanying recommended resources to achieve these objectives and evaluate its initial reception by first-year radiology residents at our institution.

Methods: A retrospective multireader-multicase design was used, including non-contrast MRI performed for suspected pediatric appendicitis following non-diagnostic US from January 2014 to December 2017. Positive diagnosis was defined by surgical pathology or symptom resolution after antibiotics.
Pediatric patients with cancer predisposition syndromes are at increased risk of developing malignancies compared with their age-matched peers, necessitating regular surveillance. Screening protocols differ among syndromes and are composed of a number of elements, imaging being one. Surveillance can be initiated in infants, children and adolescents with a tumor known or suspected of being related to a cancer predisposition syndrome or where genetic testing identifies a germline pathogenic gene variant in an asymptomatic child.

To improve communication at their institution, the authors introduced a radiology report categorization system (RADCAT) that organizes diagnostic imaging reports and uses automated communication systems. The study objectives were to (1) describe RADCAT's design, (2) evaluate its implementation for appropriate imaging, and (3) evaluate the communication of important, nonurgent results with recommended follow-up.

To facilitate closed-loop communication, our institution developed a unique radiology report categorization (RADCAT) system employing automated alert notification systems. This study aimed to understand users' initial experiences with the RADCAT system and obtain feedback.

We evaluated the diagnostic accuracy and confidence in review of stroke CTA for ELVO via a smartphone-based application as compared to PACS workstation.
Patients And Methods: Seventy-six head and neck CTA studies performed for stroke from one comprehensive and seven primary stroke centers were independently reviewed remotely on smartphone by two blinded interventional neuroradiologists in actual-use circumstances.
Background: Older patients undergoing thrombectomy for emergent large vessel occlusion have worse outcomes. However, complete or near-complete reperfusion (modified Thrombolysis in Cerebral Ischemia (mTICI) score of 2 c/3) is associated with improved outcomes compared with partial recanalisation (mTICI 2b).
Objective: To examine the relationship between outcomes and age separately for the mTICI 2c/3, 2b and 0-2a groups in patients undergoing thrombectomy for anterior circulation emergent large vessel occlusion.
Background And Purpose: Within the thrombolysis in cerebral infarction (TICI) classification, TICI 2b has been historically considered successful recanalization. Recent studies have suggested that TICI 3 and a proposed TICI 2c should be separately reported from TICI 2b, in both the original (>66% reperfusion) and modified (>50% reperfusion) definitions, because of differences in clinical outcomes with greater reperfusion. The purpose of this study was to evaluate differences in early neurological improvement and independence at 90 days using the original TICI, modified TICI, and modified TICI with 2c scales.

Objective: To evaluate the clinical impact of an embolectomy technique focused on continuous aspiration prior to intracranial vascular embolectomy (CAPTIVE).
