Actual Radiodiagnosis Technologies of Hepatic Cancer
The aim of the investigation was to study the possibilities of computer tomography with intravenous contrast and multiphase scanning and magnetic resonance tomography using hepatospecific contrast substance — gadoxetic acid — in hepatic cancer diagnostics.
Materials and Methods. Within the period of 2008–2011 on the basis of Kirov Regional War Veterans Hospital and Kirov Regional Clinical Hospital there was carried out the complete clinical and radiological examination of 60 patients with hepatic cancer. Primary liver tumors were diagnosed in 23 patients. Metastatic tumors were revealed in 37 patients.
Abdominal multispiral computed tomography (CT) was performed in 45 patients (75%). 31 patients (52%) underwent magnetic resonance tomography (MRT) of abdominal and retroperitoneal organs.
Conclusion. Actual CT and MRT technologies with intravenous contrast and multiphase scanning are high-quality and informative in topical and differential diagnosis of liver tumors. The application of hepatospecific contrast substance — gadoxetic acid — expands MRT opportunities in detection and recognition of small (less than 1 cm) liver metastases.
Differential radiodiagnosis of focal liver lesions (using CT and MRT) should be based on multicentre study of morphological structure, the character of lesion vascularity, and their dynamic and organ-specific (in MRT — in hepatocyte phase) contrast.
