Nuclear Imaging Tests
Is it possible to pass a nuclear imaging stress test and the EKG to show you had a mild heart attack in the past?
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
In exercise stress test my sons doctor wrote:"optimal heart rate achieved for nuclear imaging", but my son had regular exercise stress test without nuclear imaging.What does it mean?
Hi, what are the advantages and disadvantages of iodine 131 in nuclear imaging? e.g. the cost and the abundance, the stability
I 131 for treatment: The 131 isotope of Iodine is used to treat thyroid nodules and cancers due to its long half life. It's pretty cheap, but is given as an in pt. so there is cost there. I 123 is often used for diagnosis. Also used is technetium 99m to assess blood flow to nodules. Most common thyroid screen is ultrasound. Occasionally MRI can be a good problem solver as well. ...Read more
Well...: Since you had a cardiac nuclear scan, I assume your doctors were looking for coronary artery disease. You seem to be a smoker, which makes artery disease worse. So smoking is not a good thing for you, and you should try to stop. Having said that, you are probably not in any more immediate risk for heart problem for smoking after the nuclear exam. Long term risks are greater with smoking. ...Read moreSee 2 more doctor answers
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 moreSee 2 more doctor answers
Nuclear medicinetest: A nuclear scan refer to a medical imaging study performed in nuclear medicine, using intravenous, oral administration or inhalation of radionuclide tracers ( weakly radioactive material). According to the type of radiotracers injected, the physician will be able to evaluate the function of the heart, brain, liver, kidneys, bones, lungs, as well as cancer. Inflammation, or organ infection. ...Read moreSee 2 more doctor answers
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 moreSee 1 more doctor answer
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 moreSee 2 more doctor answers
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 moreSee 2 more doctor answers
