Estimation of absolute myocardial blood flow during first-pass

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 IMAGING 2. 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 ].

Circulation 1998; 97:765-772. SUMMARY: MR perfusion imaging is becoming an increasingly common means of evaluating a variety of cerebral pathologies, including tumors and ischemia. In particular, there has been great interest in the use of MR perfusion imaging for both assessing brain tumor grade and for monitoring for tumor recurrence in previously treated patients. Perfusion imaging with dynamic susceptibility contrast (DSC)-MRI is based on the principles of tracer kinetic modeling to assess the cerebral microvasculature.
