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.

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
