Algorithm lowers number of CTs for some strokes
An imaging algorithm reduced the number of CT angiography and CT perfusion studies performed on patients with aneurysmal subarachnoid hemorrhages, a form of stroke.
An imaging algorithm reduced the number of CT angiography and CT perfusion studies performed on patients with aneurysmal subarachnoid hemorrhages, a form of stroke. The study was performed at New York Presbyterian Hospital – Weill Cornell Medical Center researchers and included 60 patients.
The algorithm identifies the most appropriate points at which to detect vasospasm with CT angiography and CT perfusion imaging. A flow chart establishes imaging pathways and time frames.
With the new algorithm, the mean number of CT examinations per patient dropped from 7.8 to 5.8, a decrease of 25.6%, according to the researchers. The number of CT perfusion exams per patient decreased 32.1% and overall cumulative radiation exposure decreased by 12.1%.
The results were published in the American Journal of Roentgenology (AJR 2010;195(1):176-180).

June 5th 2025An alternative to an open neurosurgical approach, the Visualase V2 MRI-Guided Laser Ablation System reportedly utilizes laser interstitial thermal therapy (LITT) for targeted soft tissue ablation in patients with brain tumors and focal epilepsy.
Can Abbreviated MRI Have an Impact in Differentiating Intraductal Papilloma and Ductal Secretion?
June 3rd 2025For patients with inconclusive ultrasound results, abbreviated breast MRI offers comparable detection of intraductal papilloma as a full breast MRI protocol at significantly reduced times for scan acquisition and interpretation, according to a new study.
Can AI Assessment of PET Imaging Predict Treatment Outcomes for Patients with Lymphoma?
June 2nd 2025The use of adjunctive AI software with pre-treatment PET imaging demonstrated over a fourfold higher likelihood of predicting progression-free survival (PFS) in patients being treated for lymphoma, according to a new meta-analysis.
