SPECT Image of the Heart-Topic Overview
Single photon emission computed tomography (SPECT) is a nuclear medicine imaging test. It is a type of positron emission tomography, also called a PET scan.

How to Boost Your Man's Heart Health
It’s Father’s Day, and you’ve got love in your heart for the men in your life -- your husband, your dear old dad, maybe even your brother. But it seems they might not be watching after their own hearts. They ignore this vital organ at their peril: As with women, heart disease is a leading killer of Americans. More than a half million men have heart attacks each year.Even so, fewer people have died over the past decade, largely due to more effective treatments. The American Heart Association also...

When used to detect whether a heart attack is occurring or may occur, SPECT locates areas of the heart muscle that have inadequate blood flow compared with areas that have normal flow. Inadequate blood flow means that coronary arteries are blocked and a heart attack is occurring. SPECT can also assess how bad the blood flow blockage is.
It is a noninvasive imaging scan that exposes you to radiation. For this test, your doctor injects a tiny amount of radioactive tracers through a vein in your arm. After the radioactive tracer is injected, a camera that can detect the radiation emitted by these tracers rotates around you. This creates images of your heart from different angles. Then, computer graphics are used to create three-dimensional images of your heart.
If your SPECT test is abnormal, you are considered at high risk of a heart attack.
