 Imaging Services Imaging at Parmer Medical Center has continued to offer more and more services over the years. In addition to the traditional x-ray services, PMC offers computed tomography (CT), ultrasound, bone densitometry, and Magnetic Resonance Imaging (MRI). Most services are available for both inpatient and outpatient services. CT scans or CAT scans have become an important diagnostic tool,. In a CT scan the x-ray source rotates around the patient while detectors record how much radiation is passed through the specific are to be imaged. This data is used to form a cross sectional image or a “slice”. This data can also be used to form three-dimensional models of the body part. Ultrasounds or sonograms as they are sometimes called use high frequency sound waves to create an image. An ultrasound does not use ionizing radiation to produce images so there are no documented risks involved. Bone density is an important tool in the diagnosis of osteoporosis. The information obtained from the test is used to determine a risk factor for potential fracture or to establish a baseline when treating osteoporosis. MRI is a non-invasive testing tool using powerful magnets and radio waves to form images. By targeting specific atoms in the body, MRI is able to clearly define soft tissue. MRI appointments are offered through the use of a portable unit made available to PMC on a routine basis.
