目的研究组织谐波成像技术(THI)与胃充盈造影在胃癌显像中对图像质量改善的影响以及在胃癌分期诊断中的临床应用价值.方法对120例胃癌患者分别采用基波和组织谐波成像,对因各种原因基波成像(FI)不满意患者改用THI技术,观察THI对图像质量的影响,分析THI在肿瘤病灶边界范围确定、病灶浸润深度判定中的准确性,并与手术病理结果对照.结果 24例FI成像质量满意的图像THI与FI显示了良好的一致性(P>0.05),96例FI成像图像质量不满意者在THI状态下69例得到明显改善,平均改善率为 71.9%,二者差异显著(P<0.05).在胃癌分期分析中,对病灶范围小于2和5 cm以下测值的符合率较高,分别为 85.7%和82.5%,误差范围小;>5 cm以上的测值误差范围较大,符合率仅为61.8%;对浸润深度判定与手术病理结果对照,早、中、晚各期符合率分别为 66.7%、75.0%和93.3%.本组资料中超声对肝脏转移的检出率为100%,而对单纯淋巴结转移的检出率仅为60.2%.结论 THI技术能显著改善图像质量;对小病灶范围测值与手术结果有良好的一致性;对胃癌术前分期判断准确性较高;为临床术前预测肿瘤可切除性、选择合理的治疗方案提供较为可靠的量化指标.

Objective To study the influence of tissue harmonic imaging technique(THI)on improvement of imaging quality,and the value of quantitative diagnosis of gastric carcinoma.Methods Fundamental wave(FI) and THI were performed in 120 gastric carcinoma cases,respectively.A flexible change in THI was made if any cases which were not suitable to FI.The influence of THI was observed through image quality.Results The good images of 24 cases by FI showed a well consistence with THI's (P>0.05).69 cases had a significant improvement by THI among 96 cases by FI(71.9%)(P<0.05).For node size 2 and 5 cm,the coincident rates were 85.7% and 82.5%.Error rate was very small.While the rate of the nodes >5cm was only 61.8% in gastric carcinoma.Comparing encroach depth with result of biopsy,the coincident rate for the earlier period,metaphase and advanced stage were 66.7%,75.0% and 93.3% retrospectively.The aversion rate of the liver was 100%,but the coincident rate for simple lymph node aversion was only 60.2% by ultrasound.Conclusions THI could improve image quality significantly and shows a perfectly consistence with operational result of small nodes.It also shows higher accuracy in typing the gastric carcinoma before operation.THI can be regarded as a basic diagnostic technique,which will be the fundamental guideline for treatment.
