64-row CTA tops DSA in brain aneurysm detection
Thanks to a near-perfect performance in a large cohort study in China, 64-slice CT angiography has shown it could replace digital subtraction angiography as the modality of choice for detecting suspected brain aneurysms at risk of spontaneous subarachnoid hemorrhage.
Thanks to a near-perfect performance in a large cohort study in China, 64-slice CT angiography has shown it could replace digital subtraction angiography as the modality of choice for detecting suspected brain aneurysms at risk of spontaneous subarachnoid hemorrhage.
Dr. Qi Li and an investigative team at Chongqing Medical University enrolled 108 consecutive patients with suspected intracranial aneurysms who underwent 64-slice CTA and DSA between May 2006 and June 2007. The investigators used combined DSA and surgical findings as the reference standard to compare CTA results.
Both modalities detected the same number of aneurysms. But CTA enabled radiologists to make more reassuring diagnoses with 3D techniques such as volume rendering and maximum intensity projections, which helped skirt overlapping anatomic structures and artifacts and provide accurate lesion characterizations. The findings were published in the September issue of Radiology.
Study of Ofatumumab for Multiple Sclerosis Shows 'Profoundly Suppressed MRI Lesion Activity'
April 17th 2024The use of continuous ofatumumab in patients within three years of a relapsing multiple sclerosis diagnosis led to substantial reductions in associated lesions on brain MRI scans, according to research recently presented at the American Academy of Neurology (AAN) conference.
MRI Research Suggests Link Between COVID-19 Related Brain Fog and Blood-Brain Barrier Dysfunction
February 23rd 2024For people with COVID-19 related brain fog, emerging dynamic contrast-enhanced MRI (DCE-MRI) research findings revealed blood-brain barrier disruption in multiple brain regions, including temporal lobes and the frontal cortex, up to a year after active infection.
