Despite society recommendations that cross-sectional imaging be obtained following removal of ingested button batteries, there is no published consensus on how it effectively guides clinical management. This single institution survey demonstrates a lack of uniformity by clinicians regarding which imaging findings impact management decisions, highlighting the need for further guidelines.

High-resolution vessel wall MRI in Moyamoya disease: a systematic review and meta-analysis of diagnostic and prognostic applications.
Neuroradiology

Department of Neurosurgery, Medical University of South Carolina, Charleston, SC, USA.
Purpose: Moyamoya disease (MMD) is a rare cerebrovascular disorder characterized by the narrowing of arteries at the brain's base. While cerebral angiography is the gold standard for diagnosis, high-resolution vessel wall magnetic resonance imaging (VW-MRI) has recently emerged as a non-invasive diagnostic tool. This systematic review aims to provide insights into the role of VW-MRI in enhancing the diagnosis and management of MMD.

Objectives: Phosphorus-31 magnetic resonance spectroscopic imaging (P-MRSI) is a non-invasive tool for assessing cellular high-energy metabolism in-vivo. However, its acquisition suffers from a low sensitivity, which necessitates large voxel sizes or multiple averages to achieve an acceptable signal-to-noise ratio (SNR), resulting in long scan times.
Materials And Methods: To overcome these limitations, we propose an acquisition and reconstruction scheme for FID-MRSI sequences.
Discrimination of benign, atypical, and malignant peripheral nerve sheath tumours in neurofibromatosis type 1 - intraindividual comparison of positron emission computed tomography and diffusion-weighted magnetic resonance imaging.

Department of Diagnostic and Interventional Radiology and Nuclear Medicine, University Medical Center Hamburg-Eppendorf, Martinistraße 52, 20246, Hamburg, Germany.
Background: To intraindividually compare the diagnostic performance of positron emission computed tomography (F-18-FDG-PET/CT) and diffusion-weighted magnetic resonance imaging (DW-MRI) in a non-inferiority design for the discrimination of peripheral nerve sheath tumours as benign (BPNST), atypical (ANF), or malignant (MPNST) in patients with neurofibromatosis type 1 (NF1).
Results: In this prospective single-centre study, thirty-four NF1 patients (18 male; 30 ± 11 years) underwent F-18-FDG-PET/CT and multi-b-value DW-MRI (11 b-values 0 - 800 s/mm²) at 3T. Sixty-six lesions corresponding to 39 BPNST, 11 ANF, and 16 MPNST were evaluated.
Replaced right posterior cerebral artery associated with ipsilateral superior cerebellar artery type persistent trigeminal artery variant diagnosed by magnetic resonance angiography.

Department of Neurosurgery, Saitama Sekishinkai Hospital, 2-37-20 Irumagawa, Sayama, Saitama, 350-1305, Japan.
Purpose: To describe a case in which a right replaced posterior cerebral artery (PCA) was associated with an ipsilateral superior cerebellar artery (SCA) type persistent trigeminal artery (PTA) variant.
Methods: A 53-year-old man who had been diagnosed with chronic dissection of the left vertebral artery (VA) 4 months previously underwent follow-up magnetic resonance (MR) angiography using a 3-Tesla scanner.
Results: MR angiography showed a slightly dilated left VA at the terminal segment without interval change.
Magnetic resonance imaging features of uterine adenosarcoma: case series and systematic review.

Department of Radiology, The Jikei University School of Medicine, Tokyo, Japan.
Objectives: To comprehensively summarize the characteristics of magnetic resonance imaging (MRI) findings of uterine adenosarcoma through a systematic review and case series analysis.
Methods: A literature search was conducted in MEDLINE, Scopus, and Embase databases on June 3, 2024. In total, 25 cases from 23 articles were selected, and five cases from the authors' institution were included.
