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.
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.

Small. Xrays small risk of cancer. Contrast small risk of reaction or renal damage. Go to acr accredited scanner to be safe. See radiologyinfo. Org.
No. It is a pain free procedure, if you are claustrophobic discuss this with your doctor.
No. Not at all except if IV needs placed in your vein for contrast.
Essentially no. A ct exam itself does not cause pain. If the exam is ordered with intravenous contrast, you will need an IV placed. Some people can feel the contrast as it is injected, but this is not painful. If the contrast gets escapes the IV line (an extravasation), there is the potential for pain as the contrast builds up in the soft tissues. If this occurs, you need to alert the tech performing the exam.
CT scan. Painless if without contrast.
Amount. Table moves with each rotation of the x-ray tube in the scanner.
CT scan. Computed tomography is an xray test to examine internal organs.
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.
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.
Same thing.. It means the same thing. A ct scan.
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.
No. It depends on the region of the body that is to be examined. In some instances, computed tomography is the examination of choice, but in other instances MRI or even ultrasound may be superior. The answer for what test is best is complex and depends on the clinical question being asked.
CT angiogram. It is being done much more often when it is necessary to visualize blood vessels (for example to see if there's a blockage). There is some radiation involved but it is considered much less "invasive" and has less complications than the regular type of "angiogram", where blood vessels are visualized by inserting thin tubes called catheters directly into them to inject a dye.
Yes. Many done every day. Saves you from getting a diagnostic angiogram to diagnose your problem.
Yes. Many doctors will order this test first before a more invasive test such as a routine angiogram where a catheter is inserted into the blood vessel. Because this is a ct picture it may be unclear or llimited. If the results are unclear or show a problem you may get a routine angiogram to confirm any problems and perhaps get treatment at the same time.
