Abstract
IOUS is the most sensitive method for detection of tumors in the liver parenchyma and has an irreplaceable role in the liver surgery. IOUS is currently the standard part of surgical procedures and is performed by a team of specialized radiologists and surgeons.
Performance of IOUS helps to eliminate the presence of residual tumors and provides the surgeon the information about the state of the tumor at the time of surgery. IOUS also allows monitoring of the local ablation (RFA) and control the surrounding of partial resection and exclude the residues of tumor tissue.
Our research is focused on the sensitivity and specificity of preoperative diagnostic methods (CT, MRI) compared with IOUS. For the requirement of our research, we consider the IOUS as the gold standard.
We confirm that the sensitivity of preoperative diagnostic methods is lower in a group of patients operated for secondary liver tumors compared with the group operated for primary liver tumors. The main reason of the highest sensitivity IOUS in comparison with other diagnostic metods is its higher resolution.
