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

How to distinguish "stunned" from "hibernating" myocardium on cardiac scintigraphy?

Stunned/Hibernating: Stunned myocardium has normal perfusion but abnormal wall motion. Hibernating myocardium has abnormal perfusion and abnormal wall motion. Hope this answers your question. ...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

Please tell me what does diffuse thyromegoly means in thyroid scintigraphy?

Please tell me what does diffuse thyromegoly means in thyroid scintigraphy?

Thyromegaly...: Diffuse thyromegaly means that the entire gland is enlarged. The 24 hour radio iodine uptake calculated during the scan and your thyroid function tests (blood tests) can help further clarify your condition. ...Read more

What does diffuse thyromegaly mean in thyroid scintigraphy?

Image enlarg thyroid: Thyromegaly means enlargement of thyroid gland sometimes called goiter. Most commonly enlarged gland caused by hyperthyroidism sometimes called Graves' disease.Most common cause of goiter worldwide is lack of iodine in the diet.In US, where the use of iodized salt is common,goiter more often due to the over- or underproduction of thyroid hormones or to nodules (diffuse multinodular goiter. ...Read more

Is routine dipyridamole thallium scintigraphy still used by doctors?

Is routine dipyridamole thallium scintigraphy still used by doctors?

Yes: In some hospitals it is. But Lexiscan (regadenson) has largely replaced Dipyridamole in most labs. Thallium is also still used sometimes, especially to evaluate hibernatining myocardium, but newer radionuclides have largely replaced it for routine testing. ...Read more

Thyroid uptake/scan: Is a nuclear medicine test performed to evaluate the structure and function of the thyroid. Technetium 99m pertechnetate is a radioactive material that is taken up (like iodine) in the thyroid. The radiotracer is injected into the bloodstream and a detector is used to measure the uptake. A special camera is used to generate a picture of the thyroid to assess the structure. ...Read more

Raised alkaline phos: Raised alk phos could be liver disease can be ruled out by symptoms related to liver jaundice dark urine itching abdominal pain, raised 5- nucleotidase is a test which tells you alk is liver in origin not bone. Bone cancer pain is worse than pain of osteoporosis definitely u r not pregnant so bone scinti after doing 5-nuclotidase and liver sonography less invasive. ...Read more

Having SPECT, scintigraphy, HRCT and normal CT of thorax in next few months. Had same 2 years ago. How high & dangerous is this dose of radiation?

Having SPECT, scintigraphy, HRCT and normal CT of thorax in next few months. Had same 2 years ago. How high & dangerous is this dose of radiation?

Depends reason: CT and scintigraphy all utilize considerable ionizing radiation. It depends on number and frequency of tests.Most important is reason for test. In other words if it necessary to prolong or save life then the radiation is inconsequential. If tests not making difference in quality of life, decision less strategic.Radiation effects in young individuals with potential for growth are greater. ...Read more

Unspecific septal Hypokinesis on a scintigraphy can be false-pos? All other exams (echo, stress, holter, ekg) came normal. I'm 22yo w/ chest pains.

Nuclear scan: There is a significant false positive nuclear scan rate. see http://www.acep.org/content.aspx?id=48977. Body habitus plays a role. Rarely there can be septal hypertrophy , though it is surprising it was not noted on echocardiogarm. What was the thickness of the septal wall on echo? Cardiac MRI/ CT angiogram may provide additional information. Discuss with cardiologist ...Read more

My mother has calcification in her cardiac valve and hypertension, she will have myocardial perfusion scintigraphy with medicine. Is it dangerous?

My mother has calcification in her cardiac valve and hypertension, she will have myocardial perfusion scintigraphy with medicine. Is it dangerous?

Stress test: A myocardial perfusion scan tests the blood supply to the heart muscle. A small needle is inserted into a vein but otherwise this is a noninvasive test. If done in a properly equipped and staffed facility it is a very safe test. The risk may be a bit higher if there is severe calcific aortic valve stenosis. ...Read more
