Measuring Perfusion Using Magnetic Resonance Imaging
Perfusion Magnetic Resonance Imaging (MRI) measures the rate at which blood is delivered to tissue. The measure of perfusion acts as an indicator of tissue health. Applications of perfusion imaging include the diagnosis of both acute and chronic disease and the study of micro vascular changes associated with functional cerebral activation. An influential advantage of MRI is that it has no ioniz...
متن کاملMyocardial perfusion SPECT: Perfusion quantification
Different software tools for quantification of myocardial perfusion SPECT (MPS) studies are routinely used. Several perfusion parameters can be computed automatically. Interpretation of the MPS should start with visual inspection of the rotating planar images, visual analysis of reconstructed SPECT slices and then quantitative analysis to confirm the visual impression. Quantification should be...
متن کاملDynamic Contrast Enhanced T1-weighted Perfusion MRI for Measuring Cerebral Perfusion Increase after Visual Stimulation
Introduction: Being able to measure cerebral perfusion and cerebral blood volume quantitatively is of great importance when it comes to diagnosing and treating various cerebrovascular diseases and other brain disorders. In a clinical setting, MR perfusion imaging is normally performed using dynamic susceptibility contrast imaging. When it comes to absolute quantification, this method has severa...
