title: [Complex radiation diagnosis of post-operative recurrent hepatic tumors].
abstract: The postoperative course of the disease was studied in 63 patients operated on for malignant hepatic lesion in 1990-1998. The pattern of surgical intervention-caused hepatic changes, which is observed at ultrasonography, CT, MRI, angiography, and oil-injected CT is described. Recurrences took place at the site of resection (9.5%) and outside (34.9%). Their largest number (71%) occurred in the first postresectional year. Diagnostic difficulties arose in the differential diagnosis of postoperative inflammatory changes and tumor recurrences at the site of resection (17% false positive results). Contrast MRI and intraarterial iodized oil CT proved to be the most effective radiation diagnostic techniques.
