A head-to-head comparative study of multiple imaging modalities suggests that positron emission tomography (PET) is the most accurate noninvasive test for the detection of myocardial ischemia. In a ...

A heart PET scan is a noninvasive imaging test that uses a small amount of radiation. It helps doctors understand how the heart functions and whether it is healthy. Cardiac or heart PET scans create ...

PET scans can light up tumors in the body and help doctors determine if they are cancerous or benign (noncancerous). The results of a PET scan help guide medical decisions. A PET scan is a type of ...

According to Merrill H. Stewart, MD, Ochsner Health, the test can more accurately identify high-risk patients while helping others avoid unnecessary invasive procedures. Cardiac positron emission ...

Positron emission tomography (PET) scans can detect cancer earlier than other imaging tests. But some types of cancer are harder to detect on a PET scan. In particular, they may miss cancers that ...

PET/MR imaging is used for monitoring and assessing brain function, molecular information and metabolism. Combined PET/MR imaging has improved the diagnostic power for Alzheimer’s disease, enabling ...
