目的观察增强CT、MRI与超声对肝脏局灶性病变诊断的效果。方法 74例肝内局灶性病变的患者分别进行增强CT、MRI及超声检查,然后评估诊断结果。结果超声的诊断准确率为94.6%,增强CT、MRI的准确率为90.6%,对一些特殊肝脏肿瘤患者,联合检测可提高早期诊断的检出率。结论超声对微小病灶及瘤内供血血管的显示优于增强CT和MRI,提高临床检出率。 Objective To observe the effect of enhanced CT, MRI and ultrasonography on the diagnosis of focal liver lesions. Methods 74 cases of intrahepatic focal lesions were enhanced CT, MRI and ultrasound examination, and then evaluate the diagnostic results. Results The diagnostic accuracy of ultrasound was 94.6%. The accuracy of enhanced CT and MRI was 90.6%. For some patients with special liver tumors, the combined detection could improve the detection rate of early diagnosis. Conclusion Ultrasonography is superior to CT and MRI in improving the detection rate of small lesions and blood vessels in the tumor.
