WebJan 1, 2024 · Computed tomography (CT) perfusion imaging is a routinely used technique in the field of neurovascular imaging. The progression of a bolus of contrast agent through the neurovasculature is imaged in a series of CT scans. Relevant perfusion parameters, such as cerebral blood volume (CBV), flow (CBF) and delay (Tmax), can be computed by ...

WebCT PERFUSION ACQUISITION PARAMETERS AND RADIATION DOSE. Acquisition parameters routinely used for CTP are in the range of around 100 to 200 mAs and 80 kV, producing photons with mean energy close to the K edge of Iodine to optimize contrast to noise ratio. 3 There are several techniques used in practice to reduce the effective dose. WebComputed tomography (CT)‒based perfusion imaging may be considered MEDICALLY NECESSARY to select patients with anterior large-vessel stroke for mechanical embolectomy. CT-based perfusion imaging of the brain is INVESTIGATIONAL for all other indications.
