However, the radioactive material is retained in the patient for several days after the test, during which sophisticated radiation alarms may be triggered, such as in airports. [3] Radionuclide ventriculography has largely been replaced by echocardiography, which is less expensive, and does not require radiation exposure. [citation needed]
Nuclear medicine physicians, also called nuclear radiologists or simply nucleologists, [1] [2] are medical specialists that use tracers, usually radiopharmaceuticals, for diagnosis and therapy. Nuclear medicine procedures are the major clinical applications of molecular imaging and molecular therapy.
Radionuclide therapy can be used to treat conditions such as hyperthyroidism, thyroid cancer, skin cancer and blood disorders. In nuclear medicine therapy, the radiation treatment dose is administered internally (e.g. intravenous or oral routes) or externally direct above the area to treat in form of a compound (e.g. in case of skin cancer).
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.
Angiography is a relatively safe procedure. But it does have some minor and very few major complications. 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.
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 cisternography may be used to diagnose a spinal cerebrospinal fluid leak. CSF pressure is measured and imaged over 24 hours. [2] A radionuclide (radioisotope) is injected by lumbar puncture (spinal tap) into the cerebral spinal fluid to determine if there is abnormal CSF flow within the brain and spinal canal which can be altered by hydrocephalus, Arnold–Chiari malformation ...
Theranostics, also known as theragnostics, [1] is a technique commonly used in personalised medicine.For example in nuclear medicine, one radioactive drug is used to identify and a second radioactive drug is used to treat (therapy) cancerous tumors.
