A small study reveals that perfusion CT findings of blood-brain barrier permeability above a specified volume at the time of admission in patients over the age of 65 treated with tPA can predict two “feared complications”-symptomatic hemorrhagic transformation and malignant edema-with 100 percent sensitivity and specificity.

Blood-Brain Barrier Permeability Assessed by Perfusion CT Predicts Symptomatic Hemorrhagic Transformation and Malignant Edema in Acute Ischemic StrokeAmerican Journal of Neuroradiology | Jan 1, 2011 (FREE FULL TEXT)
A small study headed by a University of Virginia radiologist reveals that perfusion CT findings of blood-brain barrier permeability above a specified volume at the time of admission in patients over the age of 65 treated with tPA can predict two “feared complications”-symptomatic hemorrhagic transformation and malignant edema-with 100 percent sensitivity and specificity. The team hopes these studies can be used to individualize the use of tPA and perhaps extend the time window for its use.

Study Shows Enhanced Diagnosis of Coronary Artery Stenosis with Photon-Counting CTA
July 10th 2025In a new study comparing standard resolution and ultra-high resolution modes for patients undergoing coronary CTA with photon-counting detector CT, researchers found that segment-level sensitivity and accuracy rates for diagnosing coronary artery stenosis were consistently > 89.6 percent.
Can CT-Based Deep Learning Bolster Prognostic Assessments of Ground-Glass Nodules?
June 19th 2025Emerging research shows that a multiple time-series deep learning model assessment of CT images provides 20 percent higher sensitivity than a delta radiomic model and 56 percent higher sensitivity than a clinical model for prognostic evaluation of ground-glass nodules.
