Patients Will Benefit from Newest CT Technology

August 1, 2014

scannerFaster scan times and more detailed, sharper images are among the benefits of a new computed tomography (CT) scanning system recently installed at Bassett Medical Center. The advanced 128-slice CT scanner offers a more effective way to detect and treat a range of life threatening illnesses including heart disease, cancer, stroke, and lung disease.

Chief of Radiology Dr. James Peters says, “This technology will translate into less procedure time for patients with sharper, more detailed images. In addition, the new scanner uses technology that allows for the most appropriate radiation exposure for each patient examination. So we’re ensuring our patients get the absolute minimum dose necessary.”

During a CT exam, the patient is placed on a table and moved incrementally through the donut-shaped scanner while an X-ray beam is projected through cross sections of their anatomy. The information from the X-ray is sent to a specialized computer that reconstructs the information into individual slices and combines them sequentially into pictures of the entire area scanned.

The new 128-slice scanner, also referred to as fast CT, captures high resolution, three-dimensional pictures of a moving heart and the blood vessels. This enables us to detect blocked arteries and coronary artery disease in the early stages without having to put every patient through a more invasive cardiac catheterization.

The new CT will also be used for interventional procedures such as CT guided biopsies. With regard to cancer, fast CT allows us to do more than just monitor changes in the size of a tumor; we can also determine how a patient is responding to therapy by observing the perfusion of a contrast agent as it moves around and through a tumor.
