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.

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. Advantages such as high spatial resolution; absence of ion ….

Estimation of absolute myocardial blood flow during first-pass

Perfusion-weighted MR imaging techniques rely either on an exogenous method of achieving perfusion contrast (ie, the administration of an MR contrast agent) or on an endogenous method (ie, the labeling of hydrogen-1 protons in water, also known as arterial spin labeling). 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 Arterial Spin Labeled MR Perfusion Imaging Danny J. J. Wang, PhD, MSCE Associate Professor Ahmanson-Lovelace Brain Mapping Center Department of Neurology, UCLA After MR perfusion imaging (if it revealed brain death), the apnea test, oculovestibular test, and other second clinical tests were performed by an experienced neurologist. Clinical examinations were repeated 12 hours later, and definitive brain death was diagnosed in consensus by the neurologist and anaesthesiologist.

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.
