CT scan (computer tomography) and PET scan (positron emission tomography) are different but related imaging techniques. A PET scan uses nuclear medicine imaging to produce a three-dimensional picture of functional processes in the body. PET scans provide metabolic information and are increasingly read alongside CT or MRI (magnetic resonance imaging) scans, which provide anatomic information Overview You will typically be based within either a radiology or medical physics department of a hospital. Non-ionising imaging techniques are generally safe which is especially reassuring when imaging sensitive patient groups, such as children. The non-ionising imaging theme also encompasses some treatment modalities which are supported by clinical scientists, includin Patient exposure to ionizing radiation from medical imaging is a topical issue. 63 Among the techniques described thus far, ultrasonography is uniquely associated with no ionizing radiation exposure. Although 4-D CT is associated with higher radiation exposures than sestamibi SPECT and SPECT/CT, the magnitude of the dose difference depends on. A medical professional reviewing an MRI. Magnetic resonance imaging is a type of imaging that doctors use to take pictures of the inside of the body. Contrast is the term used to describe special dyes that can be used in MRI tests.

Other imaging tests may be appropriate to use for planning. These include CT with or without contrast and MRA without contrast. Aortography, an imaging procedure using x-rays with contrast inserted into an artery to view the aorta and smaller arteries, may also be appropriate Hospitals and imaging centers commonly use a mixture of digital radiography techniques such as direct radiography (DR), computed radiography (CR), and mobile DR. Frequently, physicians encounter challenges when comparing DR and CR images because of inherent differences in the overall image attributes Noninvasive thermometry is one of the unique features of MRI compared with the other imaging modalities. In this lecture, the basic principles, as well as the latest techniques of MR thermometry such as acquisition acceleration, motion and field change compensation, fat and bone thermometry are explained MRI, or magnetic resonance imaging, and PET, or positron emission tomography, are techniques that are designed to create images of what is going on inside the human organism.
