Size-Specific Dose Estimate (SSDE) - Corrections based on the size of the patient. DISCUSSION CTDIvol values for the six scanners ranged from 60 mGy to 75 mGy. 25% of the raw scores had a value of 2 (barely acceptable), while 75% of the scores ranged from 3 to 5 implying a CTDIvol consistently overestimates dose to eye lens and skin. The ImPACT tool also overestimated dose to eye lenses. As such they are still useful as a conservative predictor of dose for CT neuroperfusion studies. AAPM Report No. 111 style measurements are a better predictor of both peak skin and ey … The aim of this study was to investigate differences in volume computed tomography dose index (CTDIvol) and dose-length product (DLP) values according to facility size in Japan. A questionnaire survey was sent to 3000 facilities throughout Japan.

CTDIvol vs. DLP What do they represent? CTDIvol is based on measurements obtained when scanning either a 16cm or 32 cm phantom. Essentially, it represents scanner output.

DICOMStandardBrowser. McCollough and colleagues, in their recent editorial in the May 2011 issue of Radiology ( 1 ), have dismissed volume computed tomography (CT) dose index (CTDI vol) and dose-length product (DLP) as useful measures of patient radiation dose, arguing that they do not measure the dose the patient absorbs. However, these indexes quantify the radiation Computed Tomography Dose Index (CTDIvol), in mGy according to [IEC 60601-2-44] (Clause 29.1.103.4), The Volume CTDIvol. It describes the average dose for this frame for the selected CT conditions of operation. CTDIw (mGy) is closer to the human dose profile as compared with the CTDI 100.
