What is a perfusion studies?
Perfusion studies are imaging tests that evaluate the blood flow through organs or tissues, often using radioactive tracers to identify areas with reduced blood supply. These tests can help diagnose conditions such as heart disease, strokes, and peripheral artery disease by showing how well blood is reaching specific areas of the body. Perfusion studies are commonly used in nuclear medicine and radiology.
What occurs occurs when a part of your body is subjected to extreme or constant pressure such as from a sharp or hard object?
When a part of the body is subjected to extreme or constant pressure, it can lead to a condition called pressure ulcers or bedsores.

How part of the theory of circulation was changed?
The theory of circulation was originally based on the idea that the heart was the center of circulation, proposed by Galen in the 2nd century.
