A survey of the National Library of Medicine’s PubMed database with the keywords “myocardial perfusion” Coronary Physiology at Rest and during Hyperemia. The established physiologic rationale for stress perfusion imaging Principles of Myocardial 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. 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.

Diffusion and perfusion magnetic resonance imaging. New York: Raven, 1995:296-304 [Google Scholar] Se hela listan på ahajournals.org The CT/MR Perfusion Imaging with Contrast (PERF) Integration Profile: Facilitates the exchange of contrast enhanced images containing standard attributes for timing and position Defines how the perfusion images are stored and archived into frames of one Enhanced DICOM (Multi-frame) object so that they can later be retrieved and displayed in an unambiguous way on image viewers supporting Enhanced DICOM objects. Being an MRI technique, MR perfusion has the distinct advantage of being a part of an imaging modality that is currently the most sensitive for acute ischemia, with the evaluation incorporated with other MR sequences such as DWI as part of a stroke evaluation. 21 Despite these advantages, CT scanners are more widely available than are MRI scanners for the evaluation of stroke, especially in an emergency setting. Recent studies have indicated that perfusion MR imaging, both evaluation of relative CBV by using a DSC technique and CBF by using a PASL technique, can help predict the grade of astrocytoma and the likelihood of rapid progression.

Cerebral Perfusion Weighted MRI. Perfusion MRI (pMRI) is an imaging technique used for measuring blood flow through the brain. Two types of PWI techniques are widely used: bolus tracking with exogenous contrast agents (BT-PWI), extensively used in the clinical setting, and arterial spin labeling techniques (ASL-PWI).

The application of perfusion MRI in clinical neuro-oncology hinges upon the differential expression of angiogenic processes within neoplastic tissues when compared with surrounding normal brain. All neoplastic tissues rely upon the formation of new blood vessels, a biological process known as angiogenesis, to constantly supply nutrients and remove

Results: DSC-MR perfusion imaging diagnosed brain death with a specificity of 100% (61/61) and a sensitivity of 86.8% (53/61). A cut-off value of maximum 3.5% decrease in the signal intensity time-to-course graphic was calculated by the Youden’s index and established for the to differentiate brain death from other conditions. Introduction: Computed tomography (CT) and magnetic resonance imaging (MRI) can provide detailed anatomic structures and quantitative function information for chronic obstructive pulmonary disease (COPD).
