Radionuclide angiography is an area of nuclear medicine which specialises in imaging to show the functionality of the right and left ventricles of the heart, thus allowing informed diagnostic intervention in heart failure. It involves use of a radiopharmaceutical, injected into a patient, and a gamma camera for acquisition.
A collection of parallel slices form a slice-stack, a three-dimensional representation of the distribution of radionuclide in the patient. The nuclear medicine computer may require millions of lines of source code to provide quantitative analysis packages for each of the specific imaging techniques available in nuclear medicine.

Myocardial perfusion imaging or scanning (also referred to as MPI or MPS) is a nuclear medicine procedure that illustrates the function of the heart muscle (). [1]It evaluates many heart conditions, such as coronary artery disease (CAD), [2] hypertrophic cardiomyopathy and heart wall motion abnormalities.
Radionuclide scanning of the scrotum is the most accurate imaging technique to diagnose testicular torsion, but it is not routinely available. [16] The agent of choice for this purpose is technetium-99m pertechnetate. [17] Initially it provides a radionuclide angiogram, followed by a static image after the radionuclide has perfused the tissue.
After an angiogram, a sudden shock can cause a little pain at the surgery area, but heart attacks and strokes usually do not occur, as they may in bypass surgery. The risk of complications from angiography can be reduced with a prior CT scan by providing clinicians with more information about number and positioning of the clots in advance. [19 ...

Around 11,500 Americans are diagnosed with cervical cancer each year, according to data from the Centers for Disease Control and Prevention, and in 2022, over 4,000 people died from the disease ...
A 2009 study indicated that for every 100,000 people screened with CAC testing every 5 years between ages 45 to 75 years (men) or 55 to 75 years (women), there would be 42 (men) or 62 (women) additional radiation induced cancer cases. [13]
