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 ...

Coronary artery disease is one of the leading causes of morbidity and mortality worldwide. Although it can present with an ...

Patients with an intermediate 50% to 70% stenosed coronary lesion found on CT angiography (CTA); CT perfusion may be able to determine whether the lesion needs to be treated. Patients about to undergo ...

There's nothing new about the scans, the innovations are in how they are combined into a single display that is—or eventually may be—more informative than either scan on its own, observed Dr George A ...

Adding stress myocardial CT perfusion imaging to examinations with CT angiography may safely increase diagnostic specificity and reduce the need for invasive treatments in patients with possible ...

For patients referred for evaluation of stable angina, a tiered protocol progressing from calcium scans to CT angiography (CTA) to CT myocardial perfusion imaging (MPI) appears to be a viable ...

A large, academic medical center implemented an imaging algorithm that allowed radiologists to successfully reduce the cumulative radiation exposure and number of computed tomography (CT) angiography ...

(HealthDay News) — Computed tomographic (CT) perfusion imaging shows higher overall diagnostic performance than single photon emission computed tomography (SPECT) perfusion imaging for the diagnosis ...

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 ...
