Final answer:
The type of touch not commonly used by radiologic technologists is intimate touch. They use several other touch types as part of their work with medical imaging technologies like MRIs and ultrasounds, which do not use ionizing radiation.
Step-by-step explanation:
The radiologic technologist commonly uses several types of touch, mainly therapeutic touch, palpation, and instrumental touch, for positioning patients and ensuring proper scan quality. However, they do not typically practice a type of touch known as intimate touch, which is usually reserved for personal relationships and is not appropriate in a professional medical imaging setting. In their work, technologists handle a variety of medical imaging techniques such as X-rays, CT scans, MRIs, PET scans, and ultrasounds.
Technologists must be knowledgeable about how to properly use these imaging modalities to help in diagnosing diseases. Keep in mind that only X-rays, CT scans, PET scans, and isotopic studies involve ionizing radiation, while MRIs and ultrasounds do not, making them safer alternatives when considering radiation exposure.
