Perfusion CT for Acute Ischemic Stroke
Check out the BEST NEW RADIOGRAPHY BOOK https://tinyurl.com/RadPhysicsMastery , to help one your ARRT registry. We introduce the concept of CT perfusion with focus on the case of acute ischemic stroke imaging. First reviewing why CT is an excellent modality to determine if there is a hemorrhagic stroke and then if there was not a a hemorrhagic stroke the ischemic stroke severity can be quantified with perfusion imaging by making maps of the flow parameters including: mean transit time (MTT), cerebral blow volume (CBV), cerebral blood flow (CBF), time to peak (TTP), and the maximum time (Tmax). These parameters are determined by using a model such a deconvolution from the input CT frames.
