Abstract: Objective To assess the agreement of preoperative ultrasonography (US), CT, intraoperative ultrasonography(IOUS) and intraoperative palpation in the diagnosis of liver tumors. Methods The results of preoperative US,CT, IOUS and intraoperative palpation in the diagnosis of liver tumors in 70 patients were reviewed,and the agreement of them were evaluated. Results There was a moderate level of agreement between US and the pathology and follow-up in the diagnosis of liver tumors (Kappa = 0.63). There was a high level of agreement among CT, IOUS and the pathology and follow-up(CT vs the pathology and follow-up, Kappa = 0.72;IOUS vs pathology and follow-up, Kappa = 0. 89;CT vs IOUS, Kappa =0.53), whereas the level of agreement between intraoperative palpation and the pathology and follow-up (Kappa =0.38), US and intraoperative palpation (Kappa = 0.23), US and IOUS (Kappa = 0.23) was low. Conclusions In the assessment of liver tumors,CT and IOUS have a high agreement. Although the agreement of US and intraoperative palpation were low, they were still indispensable. Four methods were integrated, will contribute to the diagnosis and treatment of liver tumors.
