The purpose of this study is to report our experience with the implementation of the ThinPrep Imaging System (TIS) in a tertiary hospital in Korea and to evaluate the effectiveness of the TIS compared to manual methods in the screening of cervical cytology.


Detection rates of cervical abnormalities in the pre- and post-TIS periods (January 2009 to February 2010 and March 2010 to December 2010, respectively) were compared. Follow-up cytological and histological results with concurrent or subsequent human papillomavirus (HPV) tests were retrieved.


ASC-US, ASC-H, LSIL, and HSIL were more frequently detected in the post-TIS period than in the pre-TIS period (p < 0.005). The proportions of correlated cases of ASC-US were 42.2 and 40.4% in the pre- and post-TIS periods, respectively. The detection rates of high-risk types of HPV in ASC-US were not significantly different between the two groups. The proportion of correlated biopsy for ASC-H, LSIL, and HSIL was similar in both periods. HPV positivity for ASC-H, LSIL, and HSIL showed no significant change between the two periods.


The TIS is potentially useful for the detection of abnormal cervical cytology on the basis of the increased detection rate of squamous cell abnormalities, with a relatively similar proportion of correlated cases compared to the manual screening method.
