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 ...

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 ...

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 ...

PARIS, France—A strategy combining fractional flow reserve (FFR) derived from computed tomography (CT) with CT perfusion imaging has demonstrated high diagnostic accuracy in identifying inducible ...

(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 ...

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 ...

GOTHENBURG, Sweden — Stroke patients selected for thrombectomy using simple noncontrast computed tomography (CT) had a similar rate of good outcomes as those selected by the more sophisticated CT ...

Advances in cardiovascular imaging have resulted in the development of multiple noninvasive techniques to evaluate myocardial perfusion and coronary anatomy, each of which has unique strengths and ...

Heart imaging specialists have shown that a combination of CT scans that measure how much blood is flowing through the heart and the amount of plaque in surrounding arteries are just as good as tests ...

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 ...
