目的 探讨融合成像技术诊断 肝脏局灶性病变的临床价值。方法 收 集我院2014年2月至2016年6月收治的发 现肝脏部位存在局灶性病变的患者63例 作为研究对象，患者均行超声及CT检 查，进并进行图像融合。比较单纯增 强CT与融合成像技术对肝脏局灶性病 变病灶数目与类型的诊断准确率。结 果 63例患者共96例病灶，增强CT病灶 检出率为95.8%(92/96)，融合成像技 术为97.9%(94/96)，差异无统计学意 义(P＞0.05)。增强CT的定性诊断符合 率为60.4%(58/96)，融合成像技术为 89.6%(86/96)，差异有统计学意义(P﹤ 0.05)。结论 融合成像技术同时具备超 声的实时性及CT的高空间分辨率，且安 全无创、简便、快速，利于提高肝脏局 灶性病变的定性诊断正确率，具有较大 临床应用价值。

Objective To investigate the clinical value of fusion imaging in diagnosis of focal liver lesions. Methods Sixty-three patients with focal liver lesions treated in our hospital between February 2014 and June 2016 were selected as the study subjects. All patients underwent ultrasound and CT examination, and image fusion was performed. The accuracy was compared between simple enhanced CT and fusion imaging in the diagnosis of the number and type of focal liver lesions. Results There were a total of 96 lesions in 63 patients. The detection rate of enhanced CT was 95.8% (92/96), and of fusion imaging was 97.9% (94/96) (P>0.05). The coincidence rate of qualitative diagnosis of enhanced CT was 60.4% (58/96), while of fusion imaging was 89.6% (86/96) (P<0.05). Conclusion Fusion imaging is with both the real time of ultrasound and high spatial resolution of CT. It is safety and non invasive, simple and fast. It helps to improve the correct rate in the qualitative diagnosis of focal liver lesions, with great clinical application value.
