Highly Detailed CT Scan Imaging for the Best in Diagnostic Treatment
A CT (computerized tomography) scan uses a series of X-ray views taken from many different angles to produce highly detailed, cross-sectional images (or slices) of specific areas of the body. Radiologists are able to look at each of these slices individually or combine them to create 3D images. CT technology is a valuable diagnostic tool to examine bone or tissue, blood vessels and rapidly moving organs such as the heart. Some diseases are highly predictable and often preventable, which is why Franciscan Health offers comprehensive CT screening programs.
From heart and vascular to lung, each screening program is designed to identify possible health conditions early providing more treatment options and improved outcomes. In fact, we were the first in the state of Indiana and to offer a lung CT screening program for the early detection of lung cancer. CT is also useful for examining patients who are unable to hold their breath, like trauma victims, acutely ill patients and the elderly.
CT scans are often used for:
Franciscan Health offers the latest CT scan technology
64-slice CT imaging gives physicians the ability to see more anatomical detail in only a fraction of the time. The 64-slice CT scanner obtains high-resolution images as thin as a credit card, which are then used to create a 3D view of your anatomy for your doctor to analyze. The 64-slice CT scanner can also capture the image of an organ in one second and can scan the entire body in ten seconds.
The reduced scanning time offers many advantages:
- It can be difficult for young children to hold still for the longer times required with older scanners.
- People with breathing problems often find it difficult to hold their breath for 30 seconds or more, since that is simply longer than most patients with advanced pulmonary conditions can manage.
- There is no required recovery time; patients can leave as soon as their exam is complete.
- There are fewer risks compared to traditional angiography, since an arterial puncture is not required.
- It is less expensive than traditional angiography.
- Just as important, the amount of radiation a patient receives is also reduced with a new feature called dose modulation.
What to expect during a CT scan
The patient is placed on a horizontal table and positioned according to the requirements of the body section being examined. Most single procedures can be completed in less than 15 minutes but some procedures can take up to 1 – 1.5 hours to complete. Commonly heard sounds during the scan are circulating air, humming, clicks and whirring. The technologist uses a microphone and speaker system to communicate with the patient during the exam. Instructions are given regarding breathing requirements. The length of time a patient is required to hold breath is generally 15-20 seconds or less. Some exams require pre-procedure preparation for better imaging of certain body parts. This can include drinking a barium liquid (12 oz.) or the use of contrast (dye) to be injected through a vein during the examination.
