Radiation doses from CT in the Sultanate of Oman.

The computed tomography dose index (CTDI), dose-length product (DLP) and the effective dose were determined for a range of CT examinations in the Sultanate of Oman. There was a wide variation in CTDI. This shows that there is a variation in both scanner design and the exposure settings used by hospitals. There was also a wide variation in DLP and effective dose, suggesting that in some cases too many slices are taken. Therefore, standard protocols should be designed and adhered to in order that radiation doses may be reduced in the future.
