From the PSA tests during your Casodex and Zoladex treatments, it appears that these have stopped working by now.

CT Dose Index CT dose index (CTDI) is the standardized measure of the radiation output of a CT system, Currently used measures are the CTDI100 and CTDIw, modified to CTDIvol for modern helical scanners. 4. For abdomen CT, the inter-center variation for the different age groups ranged from a factor of 5.0–14.2 for the CTDIvol (6.6–15.4 for the DLP), the highest variation being for the age group 11–17 y in terms of CTDIvol (2.1–29.8 mGy) and for the age group 2–5 y in terms of DLP (30–464 mGy·cm).

McCollough and colleagues, in their recent editorial in the May 2011 issue of Radiology (), 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.

CTDIvol in Context of AEC. • When Tube current modulation is used: – CTDIvol reported is based on the average mA used throughout the scan – Essentially the CTDIvol at that kVp, bowtie, collimation, rotation time and then using the average mA (CTDI is very linear with mAs) AAPM 2011 Summit on CT Dose. The maximum value of the overall dose profile of each examination was compared to five dose quantities, including CTDIvol,sum and SSDEsum by the ACR CT Dose Index Registry, scan length-weighted CTDIvol and SSDE by a CT dose monitoring platform, and "max z location CTDIvol " by a CT manufacturer.

Both function as reasonable proxies for absorbed dose but do not represent the actual patient dose. For collimations that equal or exceed 100mm (or the ion chamber length), the CTDIvol should be determined by using 100mm (or the ion chamber length) in lieu of NxT in the calculation. Example for a 100mm ion chamber: When filling out the CTDI calculation form, any N and T that give a product of 100 would be acceptable, i.e. N =1 and T = 100mm.
