Cerebral perfusion pressure (CPP) is the pressure in the arteries leading to the brain, the blood pressure in the jugular veins, and the intracranial pressure (ICP) inside the head. It must remain in a narrow range for healthy blood flow and neurological activity. Monitoring CPP is important for head injury victims. The brain is a […]
A lung perfusion scan is used to evaluate blood flow to the lungs and is often done with a lung ventilation scan. A radioactive tracer is injected into the patient, and an imaging machine takes images to identify areas where blood supply is inadequate. Risks are low, but patients with allergies or adverse reactions should […]
Myocardial perfusion imaging is a test that measures blood flow and function of the heart using a tracer or radioactive substance. It can diagnose heart disease, assess progress, and evaluate the success of surgery. The test has two parts, one at rest and one under stress, and can show scar tissue, evaluate arteries, and measure […]
