What is the difference between tc 99m and tc 99

The results were compared with angiography and in eight patients with changes in blood pressure after revascularization. In two patients with branch artery stenosis, Tcm EC was definitely superior to Tcm DTPA and correctly identified the probability of stenosis on scintigraphy.

Tcm EC had better renal uptake in patients with decreased renal function and provided more dramatic evidence of renogram changes after captopril intervention, which resulted in more confident interpretation.

Sea animals can also concentrate Technetium in their bodies. Tiny amounts of Tc are part of the environment and are found in food and water.

Higher amounts may be found close to contaminated facilities such as federal weapons facilities or nuclear fuel cycle facilities. Exposure to technetium from the environment is unlikely. Most human exposure to technetium comes from the intentional use of Tcm in nuclear medicine.

Technetium can pose a health risk when it enters the body. Once in the human body, Tc concentrates in the thyroid gland and the gastrointestinal tract. However, the body constantly gets rid of Tc in feces.

As with any other radioactive material, there is an increased chance that cancer or other adverse health effects can result from exposure to radiation radiation Energy given off as either particles or rays. The Tcm used in medical diagnostics has a short, six-hour half-life and does not remain in the body. Skip to main content.
