Background And Purpose: 2D linear measurements are often used in routine clinical practice during vestibular schwannoma (VS) follow-up, primarily due to wider availability and ease of use. We sought to determine radiologist performance compared to 3D-volumetry, along with the impact of number of linear measurements, slice thickness and tumor volumes on these parameters.

Materials And Methods: Single center retrospective study with 97 patients (592 MRI studies).

Objective: To analyze cases of medial migration of vestibular schwannomas to propose an underlying mechanism.

Study Design: Retrospective chart review.

Patients: Ten patients from one institution with sporadic vestibular schwannomas that demonstrated medial migration toward the cerebellopontine angle on serial imaging were reviewed.

Article Synopsis
  • - MRI is key for checking penile pathologies because it offers high-quality images of soft tissues and can view structures from multiple angles.
  • - The review discusses MRI techniques and important anatomy related to these conditions.
  • - MRI is not only a supportive tool alongside ultrasound for trauma and infections but is also the main method for evaluating penile prostheses and complicated cases.

Noninvasive tumor control of vestibular schwannomas through stereotactic radiosurgery allows high rates of long-term tumor control and has been used primarily for small- and medium-sized vestibular schwannomas. The posttreatment imaging appearance of the tumor, temporal patterns of growth and treatment response, as well as extratumoral complications can often be both subtle or confusing and should be appropriately recognized. Herein, the authors present an imaging-based review of expected changes as well as associated complications related to radiosurgery for vestibular schwannomas.

Purpose: To evaluate demographics, academic backgrounds, and scholarly activities of Program Directors (PDs) in Abdominal Imaging Fellowships in the United States (US), emphasizing gender representation, international origins, and academic milestones.

Methods: A list of Fellowships in Abdominal Imaging programs in the US was obtained from the Society of Abdominal Radiology. The search was expanded using the Fellowship and Residency Electronic Interactive Database.

Cauda Equina Neuroendocrine Tumors (CE-NET), previously referred to as paragangliomas are a rare subset of spinal tumors, with limited data on imaging. Herein, we present a retrospective review of clinical and imaging findings of CE-NETs in ten patients who were evaluated at our institution over the past two decades. All patients had well-defined intradural lesions in the lumbar spine which demonstrated slow growth.

Background: Neurofibromatosis type 2 (NF2)-related schwannomatosis is an autosomal dominant tumor-predisposition syndrome characterized by bilateral vestibular schwannomas (VS). In patients with VS associated with NF2, vascular endothelial growth factor A inhibitor, bevacizumab, is a systemic treatment option. The aim of this study is to retrospectively evaluate NF2 patient responses to bevacizumab on VS growth and symptom progression.

Article Synopsis
  • The study aimed to evaluate synthetic MRI (SyMRI) for measuring myelin-to-white matter ratios and white matter fractions in patients with multiple sclerosis (MS) compared to non-MS patients.
  • 15 patients with MS and 15 non-MS patients underwent synthetic MRI scans, which were processed to analyze myelin content and white matter fractions in just 6 minutes.
  • Results indicated that white matter fraction was significantly lower in MS patients, along with reduced myelin volume compared to non-MS individuals, highlighting myelin loss associated with MS.
