Abstract：【Objective】To contrast the value of contrast-enhanced ultrasound and magnetic resonance imaging (MRI) in the diagnosis of small hepatocellular carcinoma under the liver capsule. 【Methods】89 patients with suspected small subcapsular liver cancer in Baoji Hospital of Traditional Chinese Medicine were selected as the research subjects from July 2019 to September 2021. All patients underwent contrast-enhanced ultrasound and MRI examination, and pathological diagnosis was used as the "gold standard". The results of contrast-enhanced ultrasound and MRI, analysis of contrast-enhanced ultrasound and MRI diagnostic efficiency and consistency were recorded. 【Results】There were 95 subcapsular liver lesions in 89 patients with suspected small subcapsular liver cancer, of which 79 lesions (83.16%, 79/95) were confirmed to be small subcapsular liver cancer by surgical pathology and puncture pathological examination. The contrast-enhanced ultrasound examination showed 77 lesions (81.05%, 77/95) with "fast forward and fast exit" signs. The peak intensity (PI) of small liver cancer lesions was higher than that of benign lesions, and the rise time (RT) and peak time (PT) of small liver cancer lesions were lower than those of benign lesions (P<0.05). MRI diagnosis revealed that 75 lesions (78.95%, 75/95) showed significant signal enhancement in the arterial phase, decreased signal in the venous phase and equilibrium phase, and significantly low signal in the hepatobiliary phase. The peak value (PV), maximum ascending slope (MSI), and maximum descending slope (MSD) of small liver cancer lesions were all lower than those of benign lesions (P<0.05), and the Kep value, Ktrans value and Ve value of small liver cancer lesions were higher than those of benign lesions (P<0.05). The consistency kappa values of pathological diagnosis, contrast-enhanced ultrasound and MRI diagnosis were 0.801 and 0.789, respectively, and the consistency kappa values of contrast-enhanced ultrasound and MRI diagnosis were 0.806. 【Conclusion】Contrast-enhanced ultrasound and MRI have similar efficacy in diagnosing small subcapsular liver cancer, and the appropriate diagnostic method can be selected based on individual conditions.
