In recent decades, the use of imaging equipment in diagnostic medicine has been a major part of the doctor's arsenal to help identify and treat medical issues and disease. One of those diagnostic tests often used is the CT scan.
A CT scan (also called a "cat scan" or computed tomography) is a quick and painless test that is used to identify different medical issues or disease. Unlike the two-dimensional images from an X-Ray, a CT scan is most commonly used to provide three-dimensional views of the patient's head, chest, heart, colon, abdominal organs and blood vessels. On average 70 million patients annually have a CT scan. Because of the high resolution a CT scan provides, a doctor can identify subtle differences in tissue density and organ health that may not be seen otherwise. Sometimes a doctor will request a contrast agent be used to better highlight different areas under scrutiny.
While a CT scan has an incredibly low level of risk, they do emit slightly more radiation than a traditional X-ray. As a result, a patient and doctor together should discuss any concerns regarding the radiation exposure that occurs so the patient is comfortable with the test.
On occasion, a hospital or imaging center may have used CT equipment as a way to supplement other imaging equipment or to ensure they are able to continuously provide testing while another unit is down for maintenance or repair. While some may be concerned that used CT equipment may not be as reliable or provide the same level of results as new CT equipment, nothing could be further from the truth.
First, it is important to note that not all CT equipment is selected for re-sale to another hospital or imaging center. Prior to selection, the equipment will undergo thorough testing and analysis to ensure there are no major issues or problems that cannot be repaired. Before the used CT equipment is moved, all analysis and testing is documented. Once the used CT equipment is received by the equipment dealer, the CT will undergo additional testing and analysis, as well as receive any required upgrades or part replacement.
Once the equipment is deemed fit for use, the used CT equipment will be shipped to the new imaging center or hospital. Experienced used CT equipment professionals will install the CT scanner and conduct additional testing. The equipment will not go into patient use until these professionals are satisfied that the equipment is functioning properly. Due to the extensive testing this equipment undergoes throughout the process, patients should not have any concerns if their test is done using used CT equipment.
