Imaging

The production of images by radiologic, ultrasound, or magnetic resonance imaging (MRI) techniques.

The enhancement of memory through mentally picturing information.

A technique for creating pictures of sections of the body, using scanners attached to computers.

A term which covers the variety of technologies which result in pictures (images) of body structures or functioning. The first imaging technology was, perhaps, medical illustration. Then came conventional radiology (X-ray). The next technology to gain prominence was computed tomography (CT) scanning. To these have been added magnetic resonance imaging (MRI), diagnostic ultrasound, single photon emission tomography (SPET), and positron emission tomography (PET). Many former Departments of Radiology in hospitals are now called Departments of Imaging.

The production of a picture, image, or shadow that represents the object being investigated. In diagnostic medicine the classic technique for imaging is radiographic or x-ray examination. Techniques using computer-generated images produced by x-ray, ultrasound, or magnetic resonance are also available.
