This paper illustrates the probability of indicating presence of eighth nerve tumors with conventional radiographic equipment found in any approved hospital. A knowledge of precise radiographic technique by both the radiologic technologist and the radiologist, as well as a detailed understanding of the basic anatomy, is required. It is essential that the sharpest possible collimation of the x-ray beam be made by using a 5- to 7.6-cm diameter heavy cylinder at 91.4-to 101.6-cm distances without a Bucky diaphragm. By this means it is possible to demonstrate the intimate details required for diagnosis of lesions of the petrous pyramid and the eighth nerve canal. The presentation includes three proven cases to indicate how approximately 90% accuracy can be achieved by this method.

A report from a conjoint committee of the American College of Radiology and the American Society of Radiologic Technologists indicates that sufficient personnel are being educated for the profession. It is estimated that there are 130,000 persons operating radiographic equipment of which 100,000 are licensed or certified. On the average, a radiologic technologist performs 2,597 examinations per year. Manpower needs are highest in the South, South-west and Plains regions, with an excess in the West and Northeast. Most registered technologists who leave the profession do so for personal reasons, such as family commitments.
