Core Tip
Core tip: American Association of Physicists in Medicine (AAPM) report 204 has proposed a new method, “Size specific dose estimate” (SSDE) to represent more accurate estimations of patient doses. In this study we evaluated the feasibility of SSDE in clinical setting and figured out the shortcomings of the technique. We measured diameters in 50 patients at every 5 cm interval in addition to the maximum, minimum and mid-location on both localizer radiograph and transverse computed tomography (CT) images. SSDE values were calculated based on AAPM report look-up tables. Obtained SSDE values at each level were compared to each other as well as to CT dose index volume.
