Advances in diagnostic radiology: problems and prospects.
The advances in diagnostic radiology are summarized under the headings of new techniques, new procedures and new programs. The most dramatic progress has occurred in the field of imaging technology, where computerized tomography (CT) has revolutionized the approach to brain imaging. Less obvious and secure is the position of body CT imaging, partly a result of technological deficiencies but also, as a result of imaging potential. Improved image amplification and angiographic techniques have made possible interventional radiographic procedures that hold great promise for the future. Radiologists with an interest in diagnostic oncology must play a dominant role in helping guide these new advances and direct the more appropriate application of conventional radiographic techniques in the diagnosis and followup of neoplastic diseases.
