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 ...

Spectrum Dynamics installs the cutting-edge methodology for attenuation correction for its D-SPECT® Series digital camera that eliminates need for CT transmission scan and multiple-positions scans.

Nuclear cardiology is one of the most widely used non-invasive techniques for the assessment of coronary artery disease and other cardiovascular conditions. It has proved to be a cost effective tool ...

Nuclear cardiac testing is most appropriate in the diagnosis of CAD in patients who have an intermediate likelihood of disease. Low-risk patients may need no additional testing, while high-risk ...

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

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 ...

Researchers have developed a computed-tomography-based protocol that identifies both narrowing of coronary arteries and areas of myocardial ischemia -- restricted blood flow to heart muscle tissue -- ...

Myocardial perfusion imaging is an emerging technique to help triage patients presenting to the emergency room with chest pain and who present with a normal or non-diagnostic electrocardiogram. The ...
