The field of diagnostic radiology has incorporated many exciting new procedures and technical developments during its 85-year history since the discovery of the x-ray in 1895. But no period has been more fruitful, perhaps, than the last decade when developments have appeared at a remarkable pace. Through all these changes, however, the fundamental goals of diagnostic radiology have remained unaltered. Basically, these goals are:
o To develop increasingly less-invasive procedures;
o To obtain the maximum diagnostic information possible at a given dose, or the necessary information at the minimum dose;
o To increase the flexibility and convenience of various methods in obtaining diagnostic information;
o To accomplish these objectives in a cost-effective manner.
