Conventional X-RayReduced radiation dose with high resolution immaging
Despite the new technologies, conventional X-ray remains the primary choice as regards diagnostic imaging, especially for bone and joint pathologies. As X-rays are directed at a body part, pathological changes are revealed. Organs have different densities, and X-rays reflect varying contrast levels. Dense matter such as bones produce bright/whitish images, while soft tissue including muscles are shown in different shades of grey.
The Omega Diagnostic Centre uses a HiRes digital X-ray unit (Siemens MULTIX IMPACT). It enables examinations with reduced radiation dose and highest image quality by means of a flat detector.
Patients should have some key facts in advance of their X-ray examination:
About 5 minutes.
Items of clothing as well as foreign objects such as jewellery, watches etc. must be removed before the scan. A lead-plated apron covering the pelvic area protects the patient from radiation. The technician then positions the patient to best expose the part of the body to be scanned. Normally, the patient must assume two positions for scanning each body part. While the scan is in progress the patient needs to lie still. The patient is also instructed as to how to breathe, thus minimising body movement. After the scan is completed, the digital images are forwarded to the reporting doctor (GP).
Although X-rays do not directly produce side effects, there is the risk of exposure to some level of radiation. However, this is minimised thanks to technological advances, especially those in digital equipment. Lead aprons and similar protection measures serve to prevent exposure to radiation in the most sensitive body areas.
X-ray examinations are unsuited to pregnant women.
Pregnant women cannot risk any degree of radiation exposure.
