Purpose : Analysis and optimization efforts for each medical institution when a high-risk pediatric CT scans to radiation than adults
Materials and Method : Consciousness differences were examined for dose reduction in pediatric CT including hospitals and small hospitals by telephone and visits to 29 hospitals. Other hospitals and the hospitals were compared and analyzed the CT image and dose report of pediatric patients. And pediatric CT scans were analyzed for each medical minimum·maximum dose and Food and Drug Administration recommended dose.
Result : Pediatric CT examinations surveyed using protocols provided by the companies was observed most frequently represented by 13 places (45%) of 29 hospitals. Using the hospital own Protocol and using it in combination provided by the companies was observed by each 4 places (13%). More than 86% of hospitals have no conscious effort on dose optimization and relying on companies. Adjust the dose of this hospital using the automatic dose control (AEC) and Food and Drug Administration recommended dose difference was 3.3 times. In case CT scan specific areas more than seven times each medical CTDIvol (mGy) differences occurred.
Conclusions : The high radiation sensitivity of pediatric CT examinations is needed is an optimized test according to weight and body shape. Pediatric CT scan requires a minimal dose in the readable range than the best image. Using the automatic dose control (AEC) and the appropriate pediatric dose adjustment and should be checked. In order to optimize pediatric CT scan the Radiogical technologists not only as a professional Radiology is even more important and requires a continuous effort.
