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.
FDA Clears AI-Powered Qualitative Perfusion Mapping for Cone-Beam CT

November 3rd 2020In this podcast episode, Dr. Shalom Kalnicki, from Montefiore and Albert Einstein College of Medicine, discusses the disparities minority patients face with cancer screenings and what can be done to increase access during the pandemic.
Study Reveals Benefits of Photon-Counting CT for Assessing Acute Pulmonary Embolism
April 23rd 2024In comparison to energy-integrating detector CT for the workup of suspected acute pulmonary embolism, the use of photon-counting detector CT reduced radiation dosing by 48 percent, according to newly published research.
