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 ].

Perfusion imaging is a vital tool in clinical neuroimaging, and in particular in the imaging of acute stroke patients. In magnetic resonance imaging, Dynamic Susceptibility Contrast (DSC) MR Perfusion imaging is a modality in which a bolus of contrast agent that reduces the signal intensity of T2− and T2 * − weighted images is allowed to perfuse through neural tissue while 2018-10-07 Noninvasive perfusion MR imaging using spin labeling of arterial water. In: Le Bihan D, ed.

Magnetic resonance (MR) perfusion imaging offers the potential for measuring brain perfusion in acute stroke patients, at a time when treatment decisions based on these measurements may affect outcomes dramatically.

Prognostic significance of microvascular obstruction by magnetic resonance imaging in patients with acute myocardial infarction. Circulation 1998; 97:765-772. Perfusion imaging is based on rapid imaging (echo planar imaging) of the first pass of the contrast agent and can be performed by using either a gradient-echo or a spin-echo pulse sequence. In DSC imaging, the intensity decreases in areas of greater contrast concentration due to changes in local susceptibility. 2017-01-01 2014-10-13 2017-03-21 MR perfusion imaging of the brain has proven useful in the assessment of various vascular disturbances, mainly infarct, infarct penumbra and/or territory at risk, and in autoregulatory disturbances.

Other tests, such as the computed tomography (CT) perfusion or magnetic resonance imaging (MRI) perfusion, do not use radiotracers. The areas of the brain that are very active often show greater blood supply as well as greater oxygen and glucose use.

MRI provides the high spatial and temporal resolution needed to measure blood flow to the brain . arterial spin labeling techniques utilize the intrinsic protons of blood and brain tissue, labeled by special preparation pulses, rather than exogenous tracers injected into the blood. Quick learning videos on Radiology for UG and Residents in Radiology Cardiac MR techniques are being explored for the possible perfusion assessment without IV contrast agents.

Perfusion MR imaging is increasingly being used as a diagnostic and research tool that provides maps of the regional variations in cerebral microvasculature of normal and diseased brains. With rel-atively short imaging and data process-ing times and the use of a standard dose of contrast agent, perfusion MR imaging

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 In fact, cardiac MR perfusion imaging is moving beyond tra- ditional indications such as diagnosis of coronary disease to novel applications such as in congenital heart disease, where the imperatives of avoidance of ionizing radiation and achievement of high spatial resolution are of high pri - ority. Other tests, such as the computed tomography (CT) perfusion or magnetic resonance imaging (MRI) perfusion, do not use radiotracers.
