Factors To Consider When Buying A Ct Scanner

By:


CT scans are also known as computerized tomography or for short, CTs. Ct scans consist of a sequence of X-ray views taken from a variety of different positions that generate cross-sectional internal images of bones and soft tissues. A CT scan is particularly appropriate for promptly examining people who may have internal injuries from car accidents or other types of trauma. A CT scan can also visualize the brain and with the help of injected contrast material, check for blockages or other blood vessel irregularities.

In general, physicians order CT scans in order to:

* Diagnose muscle and bone disorders, such as bone tumors and fractures
* Pinpoint the location of a tumor, infection or blood clot
* Guide procedures such as surgery, biopsy and radiation therapy
* Detect and monitor diseases, such as cancer or heart disease
* Detect internal injuries and internal bleeding

The images taken by the CT scanner are stored as electronic data files and interpreted by a radiologist who interprets these images and sends a report to the treating physician. There are many types of CT Scanners for sale, but a mid-range 16-slice system can adequately perform most routine clinical exams.

Wide bore scanners, which are similar systems with larger gantry apertures, are appropriate for oncology exams, and are also useful for scanning bariatric patients. Systems with more and thinner slices in one rotation, can handle more complex exams and more varied patient populations. The incremental benefit actually decreases as the number of slices that can be acquired increases. The smallest slice width on a 4-slice scanner, for example, is the same as that on a 16-slice scanner.

Buyers should consider several design features before purchasing a CT scanner. The basic clinical applications are quite similar for units from various manufacturers. The differences between top-of-the-line units and less complicated ones generally involve cycle time, spatial resolution, data-storage features, and helical scanning protocols. It is helpful to examine any CT scanner models you are considering while it is in use.

Sufficient training is a must due to the complexity of CT scanners. The training usually consists of one or more visits to the site by an instructor provided by the supplier. These visits can last 3-4 days, but longer visits are often desirable, depending on the expertise and experience within the facility. CT scanner users should arrange for follow-up visits 3-6 months after installation.
