Is the positron emission tomography scan a risky thing to do?

Is the positron emission tomography scan a risky thing to do?

No: It' just a diagnostic dose of radiation, like having a ct scan. (if someone thinks you need a pet scan which is a specialized test and expensive) it's probably safer for you to have it than to go without it.). ...Read more

Is there any pain involved in a positron emission tomography scan?

IV "stick": This is painless though you may feel the pain of an IV as it si stuck into you during the test. The dye is not typically allergic and no pain is involved. Some patients feel claustrophobic. ...Read more

Is there something they will give me for anxiety when i'm doing the positron emission tomography scan?

Is there something they will give me for anxiety when i'm doing the positron emission tomography scan?

Maybe: Taking a pet study is easy and painless. You will get an injection of a radioactive substance (glucose) and relax in a calm quiet area. Then the technologists will have you lay on a motorized table and you slowly are moved through two large open tubes that scan you. You won't feel anything otherwise and can keep your eyes open or closed. A relaxing medicine can be given if absolutely necessary. ...Read more

What would a neurologist refer patients for positron emission tomography scans for?

What would a neurologist refer patients for positron emission tomography scans for?

Pet indications: Pet is good to show in vivo abnormal functional areas--it has limitations--it would be nice if cheaper, more available and the pictures come superimposed on MRI pictures---may benefit us in dementia--separate radiation necrosis from active brain tumour--separate infectious from degenerative area. ...Read more

What is the use of spect (single-photon emission computed tomography) in nuclear medicine?

What is the use of spect (single-photon emission computed tomography) in nuclear medicine?

Multiple : Spect is a modality of nuclear medicine imaging that allows for 3d imaging, therefore better for diagnostic purposes. Uses include scans of the bones, lungs, heart. ...Read more

What is the definition or description of: tomography?

Reconstructed image.: Old fashioned tomograms used a moving x-ray source and flat detector to image at a certain depth in a patient. Most commonly this was used to image the kidneys. The most common tomograms used today are in cat scans, or computer assisted tomography. An x-ray source and multiple detectors spin around you, and the data is reconstructed by a computer into a slices, or cross-sections of your body. ...Read more

What is a computered tomography angiography?

What is a computered tomography angiography?

CTA: It is an intravenous contrast-enhanced CT scan with technical parameters that optimize detailed visualization of the arterial system. 3D and multiplanar data reconstructions can produce images that look similar to standard catheter angiography. From a patient's point of view, the scanning experience won't be much different from getting a standard CT scan with contrast. ...Read more

What is the definition or description of: computed tomography?

What is the definition or description of: computed tomography?

Image inside body: Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but often coronal or saggital. ...Read more

What are the risks of using a dental tomography machine?

What are the risks of using a dental tomography machine?

Risks are Relative: All x-ray exams are a balance between how much the information will help diagnose something versus the radiation dosage that must be used. Dental ct machines are made to get the most information from the lowest dosage possible and many times, we can see things that are not visible on a regular x-ray. Voice your concerns with your doc and see why he/she feels they might get a better answer for you. ...Read more

Will I get any medicine for pain when I go for the computed tomography?

Will I get any medicine for pain when I go for the computed tomography?

No: A routine ct does not cause pain. Even if contrast is given, only a small IV is placed and no pain medicine is necessary. If you have an underlying condition that causes pain and limits your ability to lay on your back you may need to talk to the doctor requesting the exam to see if you should take medicine prior to the exam. ...Read more
