The effect of mis-centering on radiation dose in CT examinations of the head: a phantom study

By Dr. MKA Karim, SM Shaffiq & Dr. INC Isa

There are several factors that may contribute to an increase in CT radiation dose, including the use of unoptimized protocols and improper scanning techniques. In this article, we summarize our recent study which was carried out to determine the precise impact on radiation dose of mis-centering during CT examinations of the head using both a standard “adult” and a low-dose protocol in a 64 slice multi-detector CT [1].
