A general guide to patient preparation for radiological investigations
Keywords: radiological procedures, patient preparation, guidelines
AbstractImaging studies form an integral part of patient work-up and knowledge of patient preparation is essential to avoid unnecessary study cancellations and delays. Radiological imaging is comprised of several different modalities. The method of imaging dictates patient preparation. Some of the imaging modalities (radiographs, fluoroscopy and CT) use ionising radiation to obtain images whereas sonar and MRI are performed without the use of ionising radiation. Ultrasound essentially uses sound waves to evaluate the acoustic properties of tissues and MRI utilises magnets and radio waves.
