HOW TO OBTAIN CME CREDITS BY READING THIS ISSUE
Pediatricians may receive Category 1 credits for the Physician's Recognition Award by reading the articles in this issue of PEDIATRIC ANNALS and successfully answering the quiz at the end of the issue. Thousands of pediatricians have taken part in this program so far, jointly administered by PEDIATRC ANNALS and Lenox Hill Hospital of New York. Complete instructions are given on page 61.
The Pre-Test below will assist you in assessing your present knowledge of the subject before reading further A CME Quiz appears at the end of the issue. To receive Category 1 CME credits, take the Pre-Test, read carefully each of the articles that follow, and complete the CME Quiz at the end of this issue. The quiz must be returned to the CME center for scoring.
As an organization accredited for continuing medical education, Lenox Hill Hospital of New York designates this continuing medical education activity as meeting the criteria for three credit hours in Category 1 for Educational Materials for the Physician's Recognition Award of the American Medical Association, provided it has been completed accordino to instructions.

The educational objective for this continuing medical education course on computed tomography and ultrasound is to provide the pediatrician with information on the newer imaging modalities that are available today and how they may be indicated for specific pediatrie problems. Case histories and photographs indicate how each of the imaging tecrv niques can be helpful in defining specific patient problems. When reading is completed, the physician should know under what circumstances ultrasound should be used to diagnose abdominal masses, ambiguous genitalia, and menstrual irregularities in pediatrie patients, how computed tomography can be helpful in certain other abdominal diseases, when computed tomography is indicated in respiratory disorders, and when ultrasound is the modality to be preferred in diagnosing diseases or malformations of the chest in infants and children. This is a continuation of the course on deep-tissue diagnosis that began in our February, 1 980, issue, and additional bibliographic references and illustrations will be found in that issue.
