Question 1

what are steps of computed tomography?

Accepted Answer

Easy test: You will need to lie still on the ct scanner table for about 5 minutes.  If the ct scan is order with contrast injection into a vein, then you need to be fasting for 4 hours before the injection and a IV line will be placed temporarily into your arm during the test.  If you are having a ct scan of the abdomen, you may need to drink oral contrast to help look at the intestines before the scan.

Question 2

what is computed tomography stimulation?

Accepted Answer

See below: I believe you are referring to the use of ct scanner in a new procedure for  implanting deep brain stimulation electrodes to treat parkinson disease, & essential tremor, under general anesthesia. The following youtube video shows the procedure: http://www.Youtube.Com/watch?V=nc7cyadeo_c.

Question 3

does it hurt to get  a computed tomography done?

Accepted Answer

No: It is a pain free procedure, if you are claustrophobic discuss this with your doctor.

Question 4

what is pitch when it comes to computed tomography?

Accepted Answer

Amount: Table moves with each rotation of the x-ray tube in the scanner.

Question 5

what is the definition or description of: computed tomography?

Accepted Answer

CT scan: Computed tomography is an xray test to examine internal organs.

Question 6

will i get any medicine for pain when i go for the computed tomography?

Accepted Answer

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.

Question 7

for visiualization of the internal structure of human body, is it best to have computed tomography?

Accepted Answer

No: It depends upon what you need to visualize. If you need to see the cerebellum, a ct scan doesn't work as well as an mri. If all you need is to look at the liver or kidneys, then an MRI is overkill compared to an easily accessible ultrasound. Plus, ct scans expose you to (unnecessary) radiation. So ask your family physician and radiologist what's the best way to find the information you need.

Question 8

how common is it for someone to need a helical computed tomography?

Accepted Answer

Very Common Test: 'helical computed tomography' -- a cat scan -- is an immensely valuable test for evaluating diseases of every part of the body. Scanners are widely available, both in hospitals and in outpatient centers, and the images obtained provide valuable insight into many diseases.

Question 9

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

Accepted Answer

3D imaging: Spect is a technique that allows 3d imaging of nuclear medicine scans, giving better spatial resolution (ie, smaller things can be seen and identified).

Question 10

could computed tomography angiography show heart problems?

Accepted Answer

CTA: Cardiac computed tomographic angiograpy is performed to try and diagnose cardiac anatomy and pathology. It doesn't diagnose everything but can provide very useful information that often yield a diagnosis if the study is ordered appropriately.
