CAT Scan

CAT scan (or CT scan) stands for Computerized Axial Tomography. It's a way of using a spinning x-ray and computer to make high-resolution images of the inside of your body. You lie flat on a table that moves through the machine quickly and takes many circular pictures. A computer then puts those pictures together to complete your exam. Any part of your body can be captured and a technologist instructs the CAT scan where to begin and end taking pictures. To enhance difficult to make out areas, some CAT scans are done after injecting you with a special contrast (dye) to clarify indistinct areas. You may also be asked to drink a mixture of contrast, which will highlight your stomach and colon.

Franklin Memorial Hospital currently has a state of the art GE 64 slice CT scanner, which was installed in 2006. The 64 slice scanner requires less scan time per exam. The previous scanner required approximately 30-40 minutes of scanning time, while the 64 slice takes only half of that time, sometimes less depending on the exam. It has given us the opportunity to offer new exams, enhance image quality, and offer more accurate diagnoses without using invasive procedures.
