MUNICH, Germany—A noninvasive strategy that integrates computed tomography (CT) angiography with CT myocardial perfusion imaging shows strong diagnostic accuracy in identifying patients who have ...

MONTREAL, QC — In stress testing using regadenoson (Lexiscan, Astellas), detection rates of myocardial ischemia were similar with less invasive computed-tomography (CT) perfusion imaging compared with ...

Dipyridamole-stress myocardial perfusion imaging with multidetector CT combined with CTA demonstrated improved diagnostic accuracy compared with individual myocardial perfusion images. Researchers ...

Recent advances in scanner technology have made the use of CT stress myocardial perfusion imaging feasible. Just how well it matches up to MR perfusion in the diagnosis of coronary artery disease (CAD ...

September 11, 2009 — A novel cardiac computed-tomography (CT) protocol that combines stress and rest myocardial perfusion imaging with coronary CT angiography in a single test can identify perfusion ...

To detect in-stent restenosis among patients with coronary stents, a new study shows the potential for improved diagnostic accuracy by adding computed tomography perfusion imaging to coronary CT ...

A research team from China investigated the microcirculation changes in liver of patients with tumor during chemotherapy by perfusion computed tomography (CT). Their study suggested that chemotherapy ...

Intravenous alteplase is the only approved treatment for acute ischemic stroke. Tenecteplase, a genetically engineered mutant tissue plasminogen activator, is an alternative thrombolytic agent. In ...

User error, not technological problems, is to blame for cases of excess radiation in computed tomography scans, the U.S. Food and Drug Administration says. The FDA has been investigating reports that ...
