Because of their ability to visualise and to quantify the distribution of radiopharmaceuticals within the body by means of external detectors, nuclear medicine techniques are basically non invasive and function oriented.

https://doi.org/10.1007/978-3-662-37957-8. The most straightforward example is probably radioisotope angiography. Whenever a radiotracer is injected intravenously the first transit through an organ can be followed in order to estimate the regional blood flow. The technical requirements are: a bolus injection of the tracer and the acquisitiobligation 发表于 2025-3-27 10:02:39

Ergebnisse der Chirurgie und Orthopädie on the fact that the heart contracts periodically. A small amount of radioactive tracer which distributes itself into the blood pool is administered to the patient (e.g. 20mCi of .Tc labelled red blood cells). Provided there is a homogeneous mixture of the radioactive tracer in the blood pool, the低三下四之人 发表于 2025-3-27 19:46:45
