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 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 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
