PENERAPAN SSDE-DIAMETER EKUIVALEN AIR SEBAGAI TINGKAT PANDUAN DIAGNOSIS TYPICAL VALUE PADA PEMERIKSAAN CT SCAN ABDOMEN PEDIATRIK

Diagnostic Reference Level (DRL) is a method of optimizing patient doses in diagnostic and intervention procedures. The DRL value obtained from the Volumetric Computed Tomography Dose Index (CTDIvol) which phantom with diameter 16 cm or 32 cm, so it not yet possible to accurately estimate dose for each patient, especially pediatric patients. American Association Physicists Medicine (AAPM) then issued water equivalent (Dw) parameter calibrate CTDIvol obtain Size-Specific Estimate (SSDE) that more specific effective. This study aims local values ​​and compare ​​in two age groups. used data 25 abdominal CT scan patients aged <15 years, divided into groups, ages 0-4 years 5-15 years. results this showed typical DRLCTDIvol ​​for were 3.09 mGy 4.39 respectively, while DRLSSDE groups 3.25 3.54 respectively. There difference 5.27% 19.36% respectively based on SSDE It can be seen year group, greater than DRLCTDIvol, conversely group lower indicates dimensional factor affects received by patient.
