- Abstract
Objective To compare the detection ability between digital subtraction angiography (DSA) and ultrasound for minimal hepatocellular carcinoma (diameter 1 cm or less), and to evaluate value of DSA in the diagnosis of small hepatocellular carcinoma. Methods From February 2017 to February 2018, 54 patients with a total of 102 small hepatocellular carcinoma lesions were detected by DSA and ultrasound respectively. The number and distribution of nodules found by DSA were recorded, and the perfusion changes of phases of hepatocellular carcinoma lesions were observed. SPSS 22.0 software was used for data analysis. Results Ultrasound found round or round-like nodules with clear boundaries and uneven internal iso-or mixed echo, which had surrounding acoustic halo with hypo echo and posterior enhancement; DSA showed abnormal blood supply of hepatic artery branch at arterial phase as well as nodular stain. The rate of detection with DSA was 77.45% (79/102), while the rate of detection with ultrasound was 59.80% (61/102), and the difference between the results had statistical significance (P<0.05). DSA indicated that the blood perfusion parameters of small hepatocellular carcinoma at arrival time, peak height and enhancement duration were (12.88±1.27), (25.04±2.31), (50.96±6.65)dB respectively, peak intensity was (32.53±2.87)dB, and peak time was (12.04±1.53)s. Conclusion Compared with ultrasound, DSA gains advantages in qualitative diagnosis and blood perfusion measurement for small hepatocellular carcinoma, and thus can be used as an examination method for high-risk groups with chronic hepatitis, liver cirrhosis, liver in multiple nodules or pure AFP elevated, so that the detection rate of small hepatocellular carcinoma can be enhanced.
