What is the difference between scintigraphy and angiography?

Scintigraphy and angiography are two important imaging techniques used in medical diagnosis. Scintigraphy is a non-invasive imaging technique that uses radioactive substances to produce an image of the body’s internal structures such as bones, organs, or tissues. It is often used for diagnosing bone diseases like cancer, infection or to assess organ function.

Angiography on the other hand is a minimally invasive procedure used to assess blood vessels. It provides detailed images of arteries, veins and other blood vessels using contrast material (contrast agent) injected into these vessels through a thin catheter tube inserted into your arm or leg at an artery. Angiography can reveal blockages in the coronary arteries and help diagnose heart diseases such as arrhythmias, heart attack or stroke before they occur.

In summary, scintigraphy is used to give general information about how body parts are functioning while angiography offers more specific details about how well certain body parts are working by providing detailed images of blood vessels and their associated structures such as valves and chambers involved in pumping blood throughout the circulatory system.
