A myocardial perfusion scan uses a tiny amount of a radioactive substance, called a radioactive tracer. The tracer travels through the bloodstream and is absorbed by the healthy heart muscle. On the scan, the areas where tracer has been absorbed look different from the areas that do not absorb it.

Ventilation/perfusion scans, sometimes called a VQ (V=Ventilation, Q=perfusion) scan, is a way of identifying mismatched areas of blood and air supply to the lungs. It is primarily used to detect a pulmonary embolus. The perfusion part of the study uses a radioisotope tagged to the blood which shows where in the lungs the blood is perfusing. The syngo.MR Neuro Perfusion Engine bundles three Neurology features for detailed brain assessments: MR Neuro Perfusion Evaluation, Automatic local AIF calculation and Perfusion-Diffusion Mismatch calculation.

Coronary artery disease (CAD) remains a major health concern and the leading cause of death in Australia. 1 Effective assessment of patients for possible CAD is a common problem in general practice. Non-invasive tests such as myocardial perfusion scans (MPS), exercise stress tests (ESTs) and stress echocardiography (using exercise or dobutamine as the stressor, as appropriate) can provide

MR perfusion techniques thus measure physiologic characteristics of tissue, while standard contrast MR is dependent on blood-brain barrier breakdown. MR spectroscopy, similar to NMR (nuclear magnetic resonance) technology used in chemistry labs, enables separation of metabolite peaks within a … Duyn, van Gelderen.

2015-10-21 · Perfusion is defined as the passage of fluid through the lymphatic system or blood vessels to an organ or a tissue. The practice of perfusion scanning, is the process by which this perfusion can be observed, recorded and quantified. The term perfusion scanning encompasses a wide range of medical imaging modalities.

dynamic contrast enhanced (DCE) MR perfusion. In summary, MR perfusion imaging is an emerging clinical tool that enables assessment of regional cerebral hemodynamics using a variety of techniques . The most common clinically applicable technique uses rapid T2- or T2 * -weighted imaging to monitor the first pass of a bolus injection of exogenous paramagnetic contrast material.
