Do not Forget to Measure the Head: Hydrocephalus Can Phenotypically Mimic Developmental Coordination Disorder.

Developmental Coordination Disorder (DCD) is a neurodevelopmental condition presenting with poor motor skill development and impaired coordination at a young age. To diagnose DCD, neurologic conditions explanatory for the phenotype, including structural brain abnormalities like hydrocephalus, must be first ruled out. However, these neurologic conditions may phenotypically mimic DCD, which can hamper their distinction.

Spatial distribution of cerebral microbleeds and FLAIR hyperintensities on follow-up MRI after radiotherapy for lower grade glioma.

Background And Purpose: Cerebral microbleeds (CMBs) and fluid-attenuated-inversion recovery (FLAIR) hyperintensities on brain MRI scans after radiotherapy (RT) are considered markers for microvascular damage and related cognitive changes. However, the spatial distribution using existing scoring systems as well as colocation of these imaging biomarkers remain unclear, hampering clinical interpretation. This study aims to elucidate the distribution and colocation of these markers in patients with lower grade glioma (LGG).

What is the added value of specialist radiology review of multidisciplinary team meeting cases in a tertiary care center?

Purpose: Multidisciplinary team meetings (MDTMs) are an important component of the workload of radiologists. This study investigated how often subspecialized radiologists change patient management in MDTMs at a tertiary care institution.

Materials And Methods: Over 2 years, six subspecialty radiologists documented their contributions to MDTMs at a tertiary care center.

Focused view CT angiography for selective visualization of stroke related arteries: technical feasibility.

Objectives: This study investigated the technical feasibility of focused view CTA for the selective visualization of stroke related arteries.

Methods: A total of 141 CTA examinations for acute ischemic stroke evaluation were divided into a set of 100 cases to train a deep learning algorithm (dubbed "focused view CTA") that selectively extracts brain (including intracranial arteries) and extracranial arteries, and a test set of 41 cases. The visibility of anatomic structures at focused view and unmodified CTA was assessed using the following scoring system: 5 = completely visible, diagnostically sufficient; 4 = nearly completely visible, diagnostically sufficient; 3 = incompletely visible, barely diagnostically sufficient; 2 = hardly visible, diagnostically insufficient; 1 = not visible, diagnostically insufficient.

Susceptibility-weighted imaging in intracranial hemorrhage: not all bleeds are black.

To correctly recognize intracranial hemorrhage (ICH) and differentiate it from other lesions, knowledge of the imaging characteristics of an ICH on susceptibility weighted imaging (SWI) is essential. It is a common misconception that blood is always black on SWI, and it is important to realize that hemorrhage has a variable appearance in different stages on SWI. Furthermore, the presence of a low signal on SWI does not equal the presence of blood products.
