Computed tomography (CT) is a noninvasive medical test that helps physicians diagnose and treat medical conditions using cross-sectional images.
CT scans use x-rays generated from a source that is rotated around the body to create 3-dimensional pictures of the body. CT scans of internal organs, bones, soft tissue and blood vessels provide greater clarity and show more details than routine x-ray exams.
CT scans help diagnose problems such as cancers, cardiovascular disease, infectious disease, trauma and musculoskeletal disorders. For instance, a CT scan is often the preferred method for diagnosing different types of cancer because the image allows a physician to confirm the presence of a tumor, measure its size and exact location, and determine the extent of the tumor's involvement with other nearby tissue.
Physicians often use CT imaging to assess for:
- Kidney stones.
- Aortic aneurysms.
- Pulmonary embolism (a blood clot in the lung vessels).
- Injuries to the liver, spleen, kidneys, bowel or other internal organs in cases of trauma.
At Perry County Memorial Hospital, patient safety is a top priority of ours. So, it makes sense that our new CT scanner, SOMATOM Definition Edge, is the top of the line in areas of safety, image clarity and speed.
One of the top features of our CT scanner includes radiation dose reduction of up to 75 percent to the patients. The radiation dose reduction technology, X-CARE, allows us to reduce radiation exposure without compromising image quality. This technique can be used for CT scanning of the neck, chest, abdomen and pelvis for all patients, including children. The illustration below shows the benefit X-CARE provides to our patients.
Additionally, over the past couple of years, PCMH has been voluntarily participating in the American College of Radiology’s (ACR) Dose Index Registry to proactively monitor and minimize the amount of radiation our patients receive. This forum receives and compiles radiation dose comparisons from CT scanners across the country and our new CT scanner has improved our CT dose ranking; enabling us to score better than some of the nation’s largest healthcare systems.
Another feature of the SOMATOM Definition Edge is superior image quality. The scanner can generate ultra-thin slices to deliver an extremely high image resolution without any increase in radiation dose. The increased image detail benefits critical cases such as emergency diagnostics and cardiovascular examinations, where every additional visible micrometer can be beneficial. Here are a few images for you to see the sharpness for yourself.
The Definition Edge CT scanner allows patients to experience a shorter scan time as well. With patients who are unable to remain still for long periods, or with scans involving fast moving organs such as the heart, the shortest possible scanning time may reduce image motion pieces. With our new scanner, a typical thorax or abdomen examination can be performed in about two seconds, potentially minimizing the need for patient breath-holding during scanning. A 6-foot patient can potentially be scanned in 8.3 seconds at full speed using the system. At PCMH, our new CT scanner can reduce patient scan times by up to 90 percent and minimize breath holds to 8 seconds or less.
