An X-ray procedure designed to visualize structures within the body that would not normally be seen through conventional X-ray procedures.
A radiological procedure that uses .x-rays to create images of successive slices of the body and its organs.
The three elongated, bony projections known as the superior, middle, and inferior turbinates or nasal conchae; singular is concha.
A radiologic technique in which a radioactive isotope is injected and the radioactive emissions are picked up by the scanning apparatus and transmitted to a computer. An image of the scanned body part is then reconstructed on the screen of a video display terminal.
A development of diagnostic radiology for the examination of the soft tissues of the body. For example, within the skull it can be used to reveal the normal anatomy of the brain, the ventricles, and other structures and to distinguish pathological conditions, such as tumors, abscesses, and hematomas. The technique involves the recording of ‘slices’ of the body with an X-ray scanner (CAT scanner); these records are then integrated by computer to give a cross-sectional image. This investigation is without risk to the patient.
