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

Ct scan, mri, nuclear medicine imaging, ivp scan, how are they different?

Ct scan, mri, nuclear medicine imaging, ivp scan, how are they different?

Quite different: Ct involves xray type radiation with cross sectional imaging in transaxial, sagittal, and coronal projections. Nuclear medicine, internal irradiation either injected intravenously, inhaled, ingested, injected subcutaneously.Ivp uses injection of contrast material for visualization of kidneys and bladder with x-ray. Mr imaging uses no ionizing radiation magnetic fields to generate x-sectional images. ...Read more

What heart scan is better, CT scanner or ultra scan?

What heart scan is better, CT scanner or ultra scan?

UltraSOUND: I think you mean cardiac ultrasound (also known as echocardiography). They look at different things. Echo sees over all function, wall thickness, chamber dimensions, valves, and can measure blood flow and pressure. Ct is for detecting calcium and looking at the coronary arteries. ...Read more

Sodium low&cortisol highi& fatigue&weight loss. Clear CT scan in Apr15. Symptoms persisted CT scan in Feb 16 clear. Could CT missed SCLC. Repeat scan?

Look outside lung: Yes CT scans can miss SCLC, especially if the scan is not a 'high resolution' scan with sufficient overlap. However, with 2 negative scans, you should look outside the lung. Head & neck cancers and esthesioneuroblastoma (tumor of nerves that sense smell) can cause this symptom pattern. Though rarer, SCLC can occur outside the lung, as well. A PET scan or whole body bone scan could help. TTYD. ...Read more

What does abnormal uptake on a thyroid nuclear scan mean?

What does abnormal uptake on a thyroid nuclear scan mean?

Several things: The result of a thyroid uptake test could be abnormally increased or decreased. In the usa, the normal thyroid uptake range is approximately 10-30% at 24 hours. An increased result may be due to various reasons including: grave's disease, multinodular toxic goiter or hashitoxicosis. A decreased uptake could be due to subacute thyroiditis, iodine or amiodarone induced thyrotoxicosis among others. ...Read more

Ct scan (Nov 2015) showed bilateral avascular necrosis of the hips without collapse. Recent lab results show wbc count is 14,000.. Multiple myeloma?

Seek medical check u: You need to tell us about your complete blood report like your Hemoglobin, Platelets and differential count(What type of white cells make up your WBC count of 14,000(% of different cells )). The hip joint changes you report are unlikely to be caused by Myeloma. A good internist can help you to sort out the cause of your high WBC count. So go see one soon. ...Read more

Is it safe to smoke after a myocardial perfusion scan thallium scan cardiac nuclear imaging?

Is it safe to smoke after a myocardial perfusion scan thallium scan cardiac nuclear imaging?

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 more

I am getting a nuclear scan and have a newborn baby?

Type of isotope: Most nuclear medicine studies are done with technetium 99m which has lower dose radiation and short half life of 6hrs. Radiation effect is small. Indium 111, thallium 201, and i 131 are higher dose isotopes which usually require longer periods such as week away from growing children. The less time exposed and the greater distance away from source are factors that reduce radiation exposure. ...Read more

Are the concerns about radiation from imaging overhyped?Just read numerous articles stating you need way more msv than a nuclear scan to be concerned?

Yes and No: For the most part, the concerns about radiation from imaging are overhyped. It is true that a patient receives a dose of radiation for every x-ray, CT and Nuclear study. But the amount is small. A patient can also receive a dose of radiation from riding an airplane, living in a house made from bricks or concrete, and dozens of other every day exposures. Doctors try to minimize medical exposures. ...Read more

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

Will a hida nuclear scan expose me to dangerous radiation?

Will a hida nuclear scan expose me to dangerous radiation?

No: All imaging tests that expose a patient to radiation should only be performed for certain conditions/symptoms. That is called appropriate use. Medical radiation is a useful tool, but it should not be used unless necessary to help make a diagnosis. Radiology is always trying to balance radiation dose with image quality. This is called alara - as low as reasonably achievable. ...Read more

What is the definition or description of: thyroid nuclear scan?

What is the definition or description of: thyroid nuclear scan?

Thyroid scan: This scan involves taking orally a small dose of radioactive iodine. The iodine is taken up by the thyroid and produces an image. "cold" areas are places with no iodine uptake. "hot" areas have a lot of uptake. The radiologist also calculates the percent uptake of the iodine. This test is important in the diagnosis of hyperthyoidism, thyroid cancer, and follow up of thyroid cancer. ...Read more

I'm getting a nuclear scan and have a newborn baby. Will this be bad for the breastmilk?

Depends: There is excretion of radioactive material after nuclear scans into breast milk. The amount depends on the type of scan and the isotope used for the scan. For example, patient scans with Tc99m products should pump and discard the breast milk for about 24 hours to be safe. With thallium, wait 3-4 days before resuming feeding. With I131, breast feeding should be delayed 4-6 weeks. Ask your Doctor. ...Read more

No salt (or just no iodinated salt) for thyroid nuclear scan?

No iodinated salt: The thyroid uptake and scan measures the ability of your thyroid gland to accumulate a radioactive form of iodine (usually i-123). Table salt or seafood contain iodine (a non-radiactive one) that compete with the radioactive iodine use during the test and thus could falsely bias the results. You can use kosher salt which doesn't have the added iodine as in regular salt. ...Read more

How long do I have to be on a low iodine diet for thyroid nuclear scan?

2 weeks: A low-iodine diet should usually be followed for 2 weeks prior to a thyroid whole-body scan. The rationale behind this is to reduce the chances of non-radiactive iodine (in food and table salt) to compete with the radioactive active iodine use for diagnosis (i-123) and treatment (i-131). ...Read more
