Nuclear Scans (Definition)

From a cardiac perspective nuclear scans are performed with either exercise or medications to examine the blood flow in the heart. Before and at peak exercise the patient is given a radio tracer which travels in the blood to the heart. Pictures are take before and after exercise and compared to evaluate for any blockages in the ...Read more

Can someone please tell me about scintigraphy procedure?

Can someone please tell me about scintigraphy procedure?

Functional imaging: Scintigraphy consists to injecting radioactive material that will be included into the metabolism of the body. For bone, the radioactive tracer will be showing the bone metabolism and for instance can depict metastasis, benign or malignant bone tumors, fractures, infections and so on. Scintigraphy is also used to look at the thyroid gland, the heart, the kidney or the gallbladder function. ...Read more

What is the process of a renal scintigraphy?

What is the process of a renal scintigraphy?

Renal function: Imaging of kidneys involves intravenous injection of tcmag3 , dtpa or dmsa, and lying on table for hour or more while imaged by gamma camera. Detection of urinary obstruction, congenital anomalies( absent kidney, horseshoe kidney), and renal hypertension, scarring from infection, sometime intrarenal cysts and masses, with subsequent correlative imaging. All tests can tell function of the kidneys. ...Read more

Skeletal scintigraphy is negative for metastatic involvement, what does this mean?

Skeletal scintigraphy is negative for metastatic involvement, what does this mean?

Negative scan...: This means that if you have a primary tumor, there is no evidence on bone scan that it has spread to bones. It is important to note that technetium bone scan is best to look for osteoblastic metastases. Some tumors can cause osteoblastic lesions whereas others are more likely to cause lytic lesions. Purely lytic lesions may not show up well on bone scan but are better seen on pet scan. ...Read more

What is myocardial perfusion scintigraphy?

What is myocardial perfusion scintigraphy?

Let me try to: Myocardial perfusion scan is a nuclear medicine procedure that illustrates the function of the heart muscle (myocardium). It evaluates many heart conditions from coronary artery disease to hypertrophic cardiomyopathy and myocardial wall motion abnormalities. The function of the myocardium is also evaluated by calculating the left ventricular ejection fraction (lvef) of the heart. Good luck. ...Read more

What is the definition or description of: bone scintigraphy?

What is the definition or description of: bone scintigraphy?

Bone scan: Bone scintigraphy ( or radionuclide bone scan) is the study of bone metabolism obtained after intravenous injection of a weakly radioactive material ( usually 99mtc-mdp) which concentrates into the bones. The scan is usually obtained 3-4 hours after the injection of the radiotracer. According to the symptoms, the scan can be localized to one site or it can be a whole-body scan, from head to toes. ...Read more
