摘要
目的探讨超声对≤２．０ｃｍ小肝癌的诊断价值。方法对５６例≤２．０ｃｍ的原发性肝癌进行灰阶超声和彩色多普勒超声分析，这些病例均经手术和病理证实。结果灰阶超声对小肝癌的检出率为８４％（５２／６２），诊断符合率为８１％（４２／５２）；彩超对小肝癌的血流检出率为８２％（１８／２２），平均阻力指数为０．７６；灰阶超声联合彩超诊断符合率为８７％（４５／５２），尤其对１．０～２．０ｃｍ小肝癌诊断符合率可达８９％（４１／４６）。结论超声对≤１．０ｃｍ的小肝癌的检出和诊断仍有一定的困难，而彩色多普勒超声对明确小肝癌的诊断有明显的协助作用。
Objective\ To evaluate the value of the ultrasound in the diagnosis of small liver cancer. \ Methods\ Fifty six patients with small hepatocellular carcinoma(HCC)(≤2.0 cm)were analyzed by using gray scale ultrasonography and color Doppler ultrasound. Results\ \ The detection rate and the diagnostic accuracy rate for gray scale ultrasonography were 84%(52/62) and 81%(42/52) respectively; the blood flow was detected within the 18 small HCCs(82%), and the mean resistive index was 0.76. The accuracy rate of gray scale ultrasonography combined with color Doppler was 87%(45/52) in the diagnosis of small HCCs, especially within 1.0￣2.0 cm lesions, the accuracy rate was 89%(41/46). Conclusions\ It is still difficult to detect and diagnose the small HCCs with ≤1.0 cm lesions, but the color Doppler should be definitely useful in the diagnosis of small HCCs.
