摘要
目的探讨胃间叶源性肿瘤(GMT)的二维超声(2D)、CDFI、动态三维表面成像(4D)、3D-CDI表现。方法分析45例GMT患者的超声表现,将其分为A组(良性或可能良性)、B组(低、中危)、C组(高危或恶性)。结果术前超声诊断GMT部位、生长方式、物理状态、起源、病理类型、性质的符合率分别为95.56%(43/45)、95.56%(43/45)、91.11%(41/45)、93.33%(42/45)、62.22%(28/45)、73.33%(33/45)。组间病灶大小差异有统计学意义;A组与B、C组回声差异有统计学意义(P均<0.05)。结论应用多种超声检查技术,可早期发现GMT。
Objective To evaluate the performances of gastric mesenchymal tumor (GMT) by transabdominal 2-dimen- sional ultrasound (2D), CDFI, dynamic three-dimension surface imaging (4D) and 3-dimensional color Doppler imaging (3D-CDI). Methods Forty-five cases of GMT underwent combined ultrasonic examinations, and ultrasonic findings were retrospectively analyzed, according to which the patients were divided into group A (benign or probably benign), group B (low medium risk) or group C (high risk or malignant). Results The accordance rate of preoperative ultrasonic diagnosis for tumor location, growth mode, physical state, origin, pathological types and being benign or malignant was 95.56 % (43/45), 95.56% (43/45), 91.11% (41/45), 93.33% (42/45), 62.22% (28/45) and 77.33% (33/45), respectively. The differences of tumor size among three groups were statistically significant, so were differences of echoes between group A and B, as well as between A and C (P〈0.05). Conclusion GMT can be early detected with combined ultrasonic tech- nologies.
