Obese patients are at risk for increased radiation exposure due to the increase in radiation needed to penetrate tissue, the risk for repeat exams due to difficult positioning and technique, an incompatibility with existing equipment, and because obese patients suffer from health conditions which require radiologic procedures more than the average public.
A 57 year old man who weighed 490 lb (223 kg). Chest radiograph shows limited diagnostic quality image with poor X-ray penetration and poor visualization of lung bases.
Inadiquate patient shielding during radiography can contribute to increased patient dose. For radiologic technologists, shielding is particularly important to protect anatomic areas of the patient near the exposure field, but should not interfere with obtaining diagnostic information.
All US States have departments which regulate Radiologic Technologist activity within the state. Some states have specific x-ray CE requirements. Check with your state’s registry to confirm exact requirements.
