Nuclear Medicine (Overview)

The medical specialty of nuclear medicine involves the use of unsealed radioactive pharmaceuticals that can help image molecular flow throughout the body. The medical use of radiopharmaceuticals also includes the treatment of some cancers and bone pain. Nuclear medicine is separate from diagnostic radiology, which utilizes the use of external (sealed) radioactivity to image the body.

What are the limitations of nuclear medicine?

Detailed anatomy: No imaging study has all of the information or answers, however nuclear medicine is especially helpful to identify physiology in the body. That is. The function. What nuclear medicine does not do well is look at the fine details of anatomy. Ct and MRI are great for looking at anatomy. ...Read more

Advantages and limitations of nuclear medicine?

Functional imaging..: Nuclear imaging allows one to see physiologic function. The use of new nuclear fusion imaging such as pet/ct allows physicians to get the best of both worlds and see anatomy and function simultaneously.

One must always remember that nuclear procedures contribute to a patient's radiation exposure but the benefits of the nuclear procedure usually outweigh the risks of the radiation. ...Read more

What is nuclear medicine? And what does it treat?

Physiologic study: Nuclear medicine involves using internal irradiation in order to define function of heart, lungs, bones, liver/spleen, stomach, thyroid gland, lymph system, kidneys, bladder, brain, parathyroid gland and gall bladder. Some isotopes are injected iv, inhaled, and some ingested. Isotopes of higher doses are used to treat thyroid diseases.Amount of irradiation controlled for individual & environment. ...Read more

Many: Nuclear medicine covers a large number of medical conditions, including diagnosis and some treatments. Scans are routinely done in for the brain, thyroid gland, parathyroid, lung, heart, liver, spleen, bone and other organs. These scans are used to diagnose multiple acute and chronic diseases. Treatment of thyroid disease and some malignancies are also performed in nuclear medicine. ...Read more

Could the benefits of nuclear medicine outweigh the risks?

Certainly: Risk of some irradiation. Dosage usually low and affects grown adult less than child. Certainly finding source of disabling pain or suffering whether gb, bone, kidney, thyroid, myocardium etc important. Always way benefits versus risk. Nuclear medicine tests determine function and physiology which usually not seen by mr, x-ray, ultrasound, or ct. Pet? Ct has bee instrumental in finding occult tumor. ...Read more

What are the advantages and limitations of nuclear medicine?

Molecular imaging: Nuclear medicine has the ability to examine the molecular basis of disease by using very low levels of radioactivity that targets the disease-specific biomarkers and specific organs. The downside is it uses radioactivity (very little) and has somewhat limited resolution, but the modern scanners are attached to other modalities such as ct or mri. ...Read more

Are nuclear medicine procedures painful? What will I experience during and after the procedure?

Not usually: The pain usually is short lived from an intravenous injection of the radiotracer. Some people experience pain from hida studies for gall bladder function and chest discomfort from cardiac stress tests. Patient is monitored by medical personnel. The patient is usually imaged in the lying down position. Imaging time is variable and can last few hours, but is intermittent and not continuous. ...Read more

How long does it take for the nuclear medicine procedures to take effect? Is it a long process and how costly is it usually?

Most tests are less: Than 1 hour to 4 hours total, with generally less than 1 hour "under the camera". The radiopharmaceutical agent (a radioactive element, usually technetium, bound to a drug) is injected (usually), and the patient waits for the agent to distribute throughout the body, and then the distribution of the radiation is imaged on the camera. A few tests require imaging at 24, or even 48 hours later. ...Read more

How does nuclear medicine cure diseases? Can anyone give an example of how nuclear medicine is used to cure diseases? I don't understand how it works.

The: The best example of how nuclear medicine is used to cure diseases is treatment of thyroid cancer or graves' disease (a form of hyperthyroidism). In both cases the goal is to destroy thyroid tissue. The thyroid gland contains a large amount of iodine which it uses to produce thyroid hormone. Once iodine is ingested, a large amount is concentrated within the thyroid gland. Nuclear medicine harnesses this principal to destroy thyroid tissue by giving the patient a radioactive form of iodine (i-131). This radioactive iodine is concentrated in the thyroid gland. The isotope primarily releases beta radiation which destroys the surrounding tissue (most of which is thyroid tissue). If there is thyroid cancer in the area, the cancer is also destroyed. ...Read more

What are radioisotopes and nuclear medicine?

Functional imaging: Nuclear medicine is use of internal ionizing radiation in form of radioisotopes by intravenous injection, ingestion, catheterization of bladder or inhalation. Functional imaging is performed of skeleton, heart, brain, thyroid, liver, spleen kidneys, bladder, lymph system, gallbladder, etc.
Gamma rays instead of xrays. Radiography and MRI are anatomic imaging. ...Read more

What's a nuclear medicine scan?

What's 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?

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

Are nuclear medicine and radiotherapy the same? If there is any difference, then please share.

Not exactly: Nuclear medicine uses isotopes mainly for functional diagnoses of disorders of gall bladder, heart, brain, lungs, thyroid, bones, kidneys and bladder. Nuclear medicine has a few therapeutic uses including thyroid ablation and therapy for prostate bone metastases. Radiotherapy can
involve radiation therapy with xray and proton beams, not considered part of nuclear medicine. ...Read more

Depends. ..: The reason for referral may be your symptoms or findings on a previous exam. For example if you are going for a nuclear stress test your reason may be chest pain or shortness of breath. If you are going for a nuclear thyroid scan your reason may be hyperthyroidism or nodules seen on prior ultrasound. Hope this helps. ...Read more

What is radiology vs nuclear medicine? What's the difference between radiology and nuclear medicine? Or are they both the same? Thank you.

Different imaging: Radiology is the study of images made by passing x-rays through the body to expose film placed against the body. Nuclear medicine creates images of the body by injecting a radioactive material into a vein. The radiation which is then emitted from the body is used to expose a camera which creates images. Nuclear medicine also uses radiation to treat thyroid overactivity and thyroid cancer. ...Read more

Can I have a stress test done without the nuclear medicine?

Not as good: Stress ekg is a very sensitive test and may show signs of stress induced ischemia, such as st depressions. However, it has low specificity, therefore your md won't be able to tell you where in your heart the problem likely is. Nuclear perfusion studies show defects in the myocardial walls giving more clues regarding the possible affected territory. ...Read more
