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. 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

Cerebral CT- and MRI perfusion: Techniques and clinical
Both strengths and shortcomings of perfusion MR imaging over standard anatomic MR imaging will be discussed as will important pitfalls of the technique. Se hela listan på ahajournals.org Samuels et al employed the MR spin-tagging response to acetazolamide challenge to study middle cerebral artery stenosis, and used the results to characterize specific patterns of impaired perfusion. In this issue of the AJNR, Kastrup et al (page 1233) suggest the use of MR arterial spin-tagging approaches with another variant of the cerebrovascular challenge—breath-holding. Traditionally, perfusion imaging of brain tumors has been performed with MR imaging, by using various perfusion imaging techniques and estimating tumor blood volume, blood flow, and permeability.

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.

Materials and methods: Forty-eight patients with contrast-enhancing and histologically proven brain tumors, 14 AAs, 17 GBMs, nine metastases, and eight lymphomas, were included in the study. Perfusion CT protocols • Variety of the perfusion CT protocols have been proposed, typically depending upon the target organ, mathematic modeling technique, CT scan configuration and clinical objective • typical perfusion CT protocol consists of a baseline unenhanced acquisition, followed by a dynamic acquisition performed sequentially after intravenous injection of CM. With the proposed technique, high SNR perfusion images are created with a limited number of signal averages.
