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 ...

The emerging advantages of positron-emission tomography (PET) myocardial perfusion imaging (MPI) for coronary artery disease (CAD) diagnosis and assessment of cardiovascular event risk has prompted ...

How Does a VQ Scan Work? The VQ scan is a nuclear scan. It measures airflow, called ventilation, and blood flow, called perfusion, in your lungs. The V and Q make up a math equation that helps doctors ...

A new radioactive tracer for positron emission tomography (PET) myocardial perfusion imaging will soon be available in the United States, and it’s expected to facilitate substantial growth in such ...

The nuclear stress test can show how blood flows through your heart muscles. This reveals how well the heart pumps blood and areas of your heart muscles that do not get enough blood. Nuclear stress is ...
