What is a myocardial perfusion defect?

Areas that are damaged or don’t have good blood flow do not absorb the tracer. The damaged areas may be called “cold spots” or “defects.” A stress myocardial perfusion scan assesses blood flow to the heart muscle when it is stressed.

What does abnormal LV perfusion mean?

Abnormal results may mean your heart isn’t pumping as well as it should. This might happen when you have heart damage or heart disease. Myocardial perfusion scans help us diagnose: Coronary artery disease.

What does LV perfusion mean?

Clinical Significance Left ventricular myocardial perfusion occurs in diastole rather than systole due to arrangement of the coronary anatomy. Coronary perfusion pressure is a significant determinant of myocardial oxygen supply; local factors regulate coronary flow across a range of coronary perfusion pressures.

What is perfusion abnormality?

Hepatic perfusion disorder (HPD), or hepatic perfusion abnormality, refers to perfusion differences between segments, subsegments, and lobes of the liver related to various causes (1). In 1997, Gryspeerdt et al (2) defined the phenomenon of HPD on contrast material–enhanced computed tomographic (CT) images.

What is myocardial perfusion SPECT?

A: Myocardial perfusion SPECT (Single-photon emission computed tomography) is a well-established test to detect coronary artery diseases and evaluate the heart’s blood supply. It is also called a cardiac stress-rest test.

What is an abnormal heart stress test?

An abnormal stress test usually means that you have blockage in heart arteries. A nuclear stress test result should be interpreted in the light of a person’s symptoms, his risk for coronary artery disease etc. The nuclear stress test has the ability to quantify the severity of abnormality.

What is nm myocardial?

Health consumers information. A Nuclear Medicine (NM) cardiac stress test involves a scintigraphic (radioactive isotope) scan of the heart in conjunction with an exercise stress test to evaluate myocardial perfusion.

What is myocardial perfusion test?

Myocardial perfusion is an imaging test. It’s also called a nuclear stress test. It is done to show how well blood flows through the heart muscle. It also shows how well the heart muscle is pumping.

What is a myocardial perfusion defect? Areas that are damaged or don’t have good blood flow do not absorb the tracer. The damaged areas may be called “cold spots” or “defects.” A stress myocardial perfusion scan assesses blood flow to the heart muscle when it is stressed. What does abnormal LV perfusion mean?
