Nuclear Scans (Overview)

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 arteries on the heart.

Are nuclear scans 100% accurate?

Are nuclear scans 100% accurate?

Nothing 100%: Accurate, nuclear medicine is a medical specialty involving the application of radioactive substances in the diagnosis and treatment of disease. In some diseases nuclear medicine studies can identify medical problems at an earlier stage than other diagnostic tests. Nuclear medicine, in a sense, is "radiology done inside out" or "endo-radiology" because it records radiation emitting from within ...Read more

Are nuclear scans accurate for diagnosing gallbladder troubles?

Yes for acute: The accuracy of cholescintigraphy (nuclear scan) for diagnosis of acute calculous cholecystitis has been greater than 95%, and the accuracy for acute acalculous cholecystitis is only slightly less. A normal scan with gallbladder visualization almost always excludes a diagnosis of acute cholecystitis. ...Read more

Difficulty walking after 3 MRI's with contrast,5 CAT scans 3 with contrast 2 Nuclear scans of skeleton with contrast all occurring with in 3 months ?

Difficulty walking: See a neurologist or neurosurgeon. A nerve conduction study and blood work to exclude a polyneuropathy or B12 deficiency is necessary. A metabolic cause rather than a structural cause is likely as the cause of the difficulty walking since imaging studies are nondiagnostic. ...Read more

Do nuclear scans expose a patient to more radiation than an X-ray or CT scan?

Do nuclear scans expose a patient to more radiation than an X-ray or CT scan?

Not usually: Depends on nuclear study. A lot of CT exams such as chest and abdomen have more radiation dose than most nuclear medicine studies. A bone scan is more dose than the CT of brain. In any event if study is necessary for diagnosis to help patient the dose becomes insignificant. ...Read more

Whats a nuclear medicine scan?

Whats a nuclear medicine scan?

A radiology test: A nuclear scan is a type of radiology study that involves getting injected (or taking orally) a small dose of radioactive tracer that can be imaged by nuclear medicine specific scanners. It is unique in that it measures the physiology of the specific tracer instead of a person's anatomy. Typically, the radioactivity dose used for these exams is minuscule and presents no/little risk. ...Read more

How come it's "safe" to take the nuclear stuff for a nuclear medicine scan?

SMALL DOSE: It is relatively safe to take nuclear stuff for medical reason because the information you receive from the nuclear medicine scan (benefit) outweighs the small risk (small amount of radiation) that you receive from it. It has less risk that an x-ray, less risk than cigarette smoking, less risk than flying from new york to los angeles, and less risk than spending a day at the beach under hot sun. ...Read more

Meckel's scan ordered for my 11 year old son. How safe is this nuclear test?

Safe: In pediatric nuclear medicine the radiation dose is calculated per weight of child.Children receive lower doses than adults. Technetium is short iived isotope with 6 hr half life. If child is having anemia or blood in stools test is worth while in trying to define source of bleeding. ...Read more
