Establishing Local Diagnostic Reference Levels in Adult Uroscan CT Examinations using Size-Specific dose Estimates (SSDE) and Ctdivol in Morocco [PDF]

CTDIvol is a commonly used dose metric in CT scans, calculated based on a 16 cm or 32 cm diameter phantom. However, CTDIvol does not provide an accurate representation of the patient’s actual dose.
