Investigating Associations Between Signal Intensity of Silent MR Angiography and Hemodynamic Information From 4D Flow MRI in Brain Arteriovenous Malformation

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Whether signal intensity (SI) on Silent MRA reflects hemodynamics in brain arteriovenous malformations (BAVMs) is unclear. Objectives To evaluate the relationship between Silent MRA SI and 4D flow‐derived hemodynamic parameters and examine whether Silent MRA‐based metrics are associated with symptomatic hemorrhage in BAVM.

Impact of 1024‐Matrix Size on Perforating Artery Visualisation in Cerebral Computed Tomography Angiography Using a 64‐Slice CT Scanner

Journal of Medical Radiation Sciences, EarlyView.
This study investigated whether using a larger image matrix (1024 × 1024 pixels instead of 512 × 512) improves the visibility of tiny brain arteries on CT scans performed with standard 64‐slice scanners. While physical image quality measurements remained unchanged, the larger matrix provided finer digital sampling of blood vessel structures, resulting ...

Management of Ruptured and Rapidly Progressive Mycotic Cerebral Aneurysms in the Setting of Unilateral Carotid Occlusion and Endocarditis with Valve Failure

Journal of Neurological Surgery Reports, 2015
Mycotic cerebral aneurysms can present unique neurosurgical challenges. We report a patient with left carotid occlusions, a ruptured left middle cerebral artery mycotic aneurysm, and a rapidly appearing unruptured left anterior cerebral artery/anterior ...

Multiple cerebral fusiform aneurysms involving the posterior and anterior circulation including the anterior cerebral artery: a case report

Folia Neuropathologica, 2017
Multiple fusiform aneurysms occurring in a single patient are very uncommon. Fusiform aneurysms affecting the anterior circulation are extremely rare and reported cases involve the middle cerebral artery and internal carotid artery. We report here a case

Response to Letter to the Editor: Impact of 1024‐Matrix Size on Perforating Artery Visualization in Cerebral CTA Using a 64‐Slice CT Scanner

Journal of Medical Radiation Sciences, EarlyView.
This response addresses a Letter to the Editor commenting on our article on 1024‐matrix reconstruction for perforating artery visualisation in cerebral CTA using a 64‐slice CT scanner (https://doi.org/10.1002/jmrs.70055). It acknowledges that integration with iterative or deep‐learning reconstruction, workflow and PACS burden, and downstream clinical ...

Applications and prospects of artificial intelligence and digital medicine in pediatric nasal skull base tumors

Pediatric Investigation, EarlyView.
Pediatric nasal skull base tumors present diagnostic and therapeutic challenges due to their deep location, nonspecific symptoms, and the narrow nasal cavity in children. Although artificial intelligence (AI) and digital medicine have advanced early diagnosis, multidisciplinary treatment, and prognosis, their application in these rare tumors remains ...
