About CT/CTA
Computed Tomography (CT) is a sophisticated imaging technique in which an x-ray source rotates around the patient producing a cross sectional slice or image, similar to the slices of a loaf of bread. These images are far superior in showing body parts than standard x-rays and greatly enhance diagnosis.
West Plains Imaging features the state of the art General Electric LightSpeed 16 CT scanner which obtains multiple images with each rotation and allows large sections of the body to be scanned in a few seconds. A scan of the chest, abdomen and pelvis can be performed in a single breath-hold. A fast scan, with less risk of blurring due to patient motion, results in clearer diagnostic images.
Conversely, small body parts can be scanned at sub millimeter slice thickness resulting in images of exquisite detail. Imaging data from large or small body parts can be reconstructed or reformatted into a variety of planes or three dimensional displays; this greatly enhances the evaluation of anatomy and pathologic conditions.
CT has many applications, including searching for cancers or tumors, brain and spine imaging, diagnosing infections, detecting kidney stones, evaluating the effects of trauma, and many other head and neck, chest, abdominal and pelvic conditions.
CT Angiography
With our new GE LightSpeed 16 CT scanner, West Plains Imaging now offers a non-invasive alternative to traditional angiography.
CT Angiography (CTA) combines the rapid acquisition of images obtained by our multi-slice scanner and combines them with 3D reformation techniques to generate pictures of the arteries of the body. Where previously this information required an invasive catheter angiogram procedure, now both large and small arteries of the body can be imaged with precision.
CT Angiography allows us to painlessly visualize the aorta, carotid, renal and peripheral arteries and to diagnose and measure aneurysms or areas of arterial narrowing more accurately and safely than costly, invasive angiography procedures. In addition, CTA is now the exam of choice for diagnosing pulmonary embolism, a common and potentially life-threatening condition where blood clots travel through the heart to lodge in the arteries to the lungs.
CT Frequently Asked Questions
What is CT?
Computed Tomography (CT) is a diagnostic procedure that combines X-rays with computer technology to create accurate, detailed diagnostic images. CT testing is non-invasive, painless and relatively fast.
What can you expect?
When you arrive at West Plains Imaging Center, the receptionist will help you with your paperwork and show you where to leave your personal belongings. When it's time for your CT, the technologist will ask you to simply lie down on a cushioned table. During the scan, it is extremely important that you remain still and quiet. The scan itself is painless. Because the scanner is open, you will be able to communicate with the technologist at all times.
What about radiation exposure?
Radiation exposure is minimized with our advanced CT. The scanner is capable of altering the radiation emitted, depending on the thickness of the body part being scanned.
How do you prepare for a CT?
You may be asked to drink a flavored liquid contrast, which highlights the intestine and helps to differentiate the intestine from other internal organs. The diagnostic quality of most CT scans is also improved by the intravenous injection of an iodine based contrast. We suggest you not eat solid food four hours prior to intravenous contrast injections. As in any medical procedure, if you are pregnant be sure to inform your physician and the staff at West Plains Imaging prior to your exam.
How long does the exam take?
The multi-slice CT scan is very fast. Once you are on the CT table, most scans are performed during one or two breath-holds. For many newer types of CT scans, the computers will process many hundreds of single images to one or more 3D volumes of your body.
When will you know the results?
Once your exam is complete, a board-certified radiologist at West Plains Imaging will look at the images. The radiologist will interpret the scans and will have a report available to your doctor within 24 to 48 hours.
If you have any additional questions, please talk to you doctor.
