Abstract: Objective To evaluate the value of low-dose computed tomographic colonography (CTC) performed with 64-slice CT in the diagnosis of incidental extracolonic lesions and its clinical significance .Methods The image data in 158 CTC examinations with two positions were retrospectively analyzed .All abdominal extracolonic lesions were recorded .According to the age ,the pa-tients were divided into two groups :elderly and non-elderly groups .The extracolonic lesions were divided into 4 groups(E1- E4) according to the clinical importance .The incidence rates in two groups were calculated respectively .Results The incidence rate of the E2-E4 level extracolonic lesions in the elderly group was higher than that in the non -elderly group ,the difference between them had statistical signficance (P< 0 .05) .Conclusion Low-dose CTC has the high diagnostic value in finding extracolonic le-sions ,and the incidence rate of extracolonic lesions with important clinical significance is increased with the age increase ,especially for the elder patients over the age of 60 years .
