Reappraisal of the Previously Described False Localizing Sign at C1-2 in Cases of Spontaneous Intracranial Hypotension.

Background And Objectives: We present an illustrative case of spontaneous intracranial hypotension (SIH) in the setting of a suspected C1-2 cerebrospinal fluid (CSF) leak that was successfully treated with muscle, collagen, and epidural blood patch. We examined the literature to identify similar cases reporting Cl-2 retrospinal fluid collections identified on imaging in the setting of SIH and quantified the success of targeted treatment to this area despite previous reports that caution about a "C1-2 false localizing sign."

Methods: A systematic search was performed identifying cases of SIH resulting from CSF leak with C1-2 fluid collection observed on imaging.

A toolbox of strategies to improve test-taking skills: a comparison of student perceptions.

Changes in the national examination structures have renewed interest in the development of test-taking strategies for professional students in the health sciences. It is often assumed that these high-achieving students have developed proficient test-taking skills and abilities before admittance. However, the assessments in these programs and for national licensure require an elevated level of reasoning and integration with clinical concepts.

Timing of diffusion tensor imaging in the management of a ruptured pediatric arteriovenous malformation: illustrative case.

Background: Diffusion tensor imaging (DTI) can characterize eloquent white matter tracts affected by brain arteriovenous malformations (AVMs). However, DTI interpretation can be difficult in ruptured cases due to the presence of blood products. The authors present the case of a ruptured pediatric AVM in the corticospinal tract (CST) and discuss how DTI at different time points informed the treatment.

SISMIK for brain MRI: Deep-learning-based motion estimation and model-based motion correction in k-space.

MRI, a widespread non-invasive medical imaging modality, is highly sensitive to patient motion. Despite many attempts over the years, motion correction remains a difficult problem and there is no general method applicable to all situations. We propose a retrospective method for motion estimation and correction to tackle the problem of in-plane rigid-body motion, apt for classical 2D Spin-Echo scans of the brain, which are regularly used in clinical practice.
