Introduction. Perfusion imaging is a vital tool in clinical neuroimaging, and in particular in the imaging of acute stroke patients.

Cardiac magnetic resonance imaging perfusion (cardiac MRI perfusion, CMRI perfusion), also known as stress CMR perfusion, is a clinical magnetic resonance imaging test performed on patients with known or suspected coronary artery disease to determine if there are perfusion defects in the myocardium of the left ventricle that are caused by narrowing of one or more of the coronary arteries

Rapid advancements in both acute stroke therapy and perfusion imaging techniques have resulted in continuing redefinition of the role Dynamic susceptibility contrast (DSC) MR perfusion is one of the most frequently used techniques for MRI perfusion, and relies on the susceptibility induced signal loss on T2*-weighted sequences which results from a bolus of gadolinium-based contrast passing through a capillary bed. The most commonly calculated parameters are rCBV, rCBF, and MTT . Coelho-Filho OR, Rickers C, Kwong RY, Jerosch-Herold M. MR myocardial perfusion imaging. Radiology 2013; 266:701-725.

Most of the time this is done in association with contrast enhancement but future techniques are promising for the possibility of being able to do it without contrast enhancement. MR perfusion is often done in situations of tumors of the brain as well as ischemic injuries (stroke). MR perfusion weighted imaging. Perfusion weighted imaging is a term used to denote a variety of MRI techniques able to give insights into the perfusion of tissues by blood. There are three techniques in wide use to derive one or more perfusion values: techniques. dynamic susceptibility contrast (DSC) MR perfusion.

MR perfusion imaging refers to several recently developed techniques used to non-invasively measure cerebral perfusion via assessment of various hemodynamic measurements such as cerebral blood volume, cerebral blood flow, and mean transit time. MR Myocardial Perfusion Imaging - PubMed. Contrast material-enhanced myocardial perfusion imaging by using cardiac magnetic resonance (MR) imaging has, during the past decade, evolved into an accurate technique for diagnosing coronary artery disease, with excellent prognostic value.

Perfusion • Perfusion is the process of passage of blood from an arterial supply to venous drainage through the microcirculation (capillary bed). It is a fundamental biological function tha The cellularity or perfusion of the tumor can be noninvasively assessed using diffusion-weighted imaging (DWI) and dynamic contrast-enhanced MRI (DCE-MRI), respectively. The apparent diffusion coefficient (ADC) calculated via DWI has been shown to be related to disease-free survival in NPC [ 9 ].
