چکیده
Over the past several years, the technological advances in the field of body imaging have been almost too numerous to catalogue. Each modality goes through a cyclical pattern of evolution. In the earliest phase of this evolution, most research is descriptive and anecdotal in nature. As a modality becomes established, it enters the second phase, in which it is touted as being superior to all prior conventional modalities. The third phase represents a backlash effect in which the shortcomings of a new technique and its inferiority to prior modalities are stressed. Finally, the technical development of a new modality reaches a plateau, the literature reflects an equality with earlier techniques. It is during this phase that the true cost-effectiveness of a new imaging technique and its impact on patient care are established. All new imaging modalities go through these phases. Most academic radiology departments are composed of single modality advocates who fail to see the interrelationships among the available imaging techniques. The radiologists must be prepared to offer unbiased aid to the referring clinicians in choosing the most cost-effective procedure from the radiological armamentarium. Nowhere is this more relevant than in imaging patients who have cancer where the range of anatomy and pathology to be imaged is infinite. Close co-operation between the clinician and radiologist is essential and a clear understanding of the purpose of the imaging is mandatory.
