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

What is nuclear magnetic resonance spectroscopy?

What is nuclear magnetic resonance spectroscopy?

MRS or MRI: MRI is magnetic resonance imaging a type of medical imaging MRS is MR spectroscopy a rarer medical type of exam based on the science behind MRIs in part aimed at either parts of the brain or perhaps skeletal muscle to evaluate metabolism at times....both would be done in an MRI facility. when developed the nuclear part of both was dropped so as to not scare people about it.... ...Read more

What is a nuclear myocardial perfusion study?

What is a nuclear myocardial perfusion study?

Stress Test: That uses a radioactive tracer to evaluate blood flow in the coronary arteries. Images are taken at peak exercise and at rest . These images are able to compare blood flow to the heart in specific territories supplied by each coronary artery and any flow disparity would be consistent with a potential blockage in that artery. ...Read more

Can nuclear medicine procedures affect CT scans?

Can nuclear medicine procedures affect CT scans?

Not usually: Not usually nuclear medicine affecting ct but the opposite. However ct scan with intravenous iodine contrast materials can affect thyroid scans and thyroid uptake. Renal GFR studies using glofil with i125 are also affected by iodine contrast of ct. ...Read more

Will a nuclear hida scan show pancreatic stones or bile duct stones?

Will a nuclear hida scan show pancreatic stones or bile duct stones?

No: Hida scan is a functional exam to reveal if the bile duct is blocked by a stone or tumor. If blockage is suspected by the results, an MRI of the bile ducts (mrcp) is frequently the next step to visualize the blockage. ...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

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

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

Is a biliary scan a pipida or hida with cck injection?

Is a biliary scan a pipida or hida with cck injection?

Biliary scan=hida : Yes a biliary scan is a hide or pipida scan. Cck may or may not be used during the study. If they are going to calculate how well your gallbladder contracts to stimulation...They very likely will use cck. ...Read more

Could sestamibi nuclear stress test only evaluates left ventricular function?

Could sestamibi nuclear stress test only evaluates left ventricular function?

NO: Nuclear stress test are done to evaluate coronary circulation/ blockages/CAD. As lagniappe they provide info re LV function. However, there are less expensive and invasive test that evaluate LV function just as well or better, like echocardiography ...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

Will a contrast dye CT scan always show small gallstones in bile ducts?

Will a contrast dye CT scan always show small gallstones in bile ducts?

No: Contrast does not usually enter the bile ducts or gallbladder except under certain unusual circumstances. Gallstones and bile duct stones can often be seen in a non contrast ct scan, but they will also be detected in a carefully performed ultrasound exam. ...Read more

Nuclear stress test and cardiac coronary CT angiogram, which do you recommend?

Nuclear stress test and cardiac coronary CT angiogram, which do you recommend?

Depends on situation: Nuclear stress test involves looking at perfusion of heart for defective areas representing coronary artery disease looking for areas of permanent damage versus areas that are reversible possible related to area of coronary narrowing. Coronary ct angiogram looks at anatomy of coronary arteries looking for areas of narrowing and blockage.Answer depends on information physician needs and insurance. ...Read more
