胃癌的诊断迄今主要依靠X线钡餐及胃镜检查,自B型超声应用以来,对于胃癌的诊断又有了一种新的影像诊断方法。为了客观地评价,本文对39例胃癌病人进行了B型超声扫查诊断并作了比较分析,现报告如下。方法 1985年7月至1987年11月,应用AlokaSSD-256和RT-2600线阵型实时超声显像仪,探头频率3.5MHz。动态范围1～63dB。灵敏度调至胃壁层次显示最佳为宜。对39例胃癌病人进行扫查诊断。扫查前禁食水。病人取仰卧位。扫查胃区及周围脏器,然后嘱病人饮温开水500ml,取坐位或站立位,移动探头,在胃投影区
The diagnosis of gastric cancer has so far mainly relied on X-ray barium meal and gastroscopy. Since the application of B-mode ultrasound, there has been a new imaging diagnosis method for the diagnosis of gastric cancer. In order to evaluate objectively, 39 cases of gastric cancer patients were diagnosed with B-mode ultrasound scans and compared and analyzed. The current report is as follows. Methods From July 1985 to November 1987, the Aloka SSD-256 and RT-2600 line array real-time ultrasound imaging systems were used. The probe frequency was 3.5 MHz. Dynamic range 1 ~ 63dB. It is advisable to adjust the sensitivity to the stomach wall level. 39 cases of gastric cancer were scanned for diagnosis. Fasting water before scanning. The patient takes a supine position. Scan the stomach area and surrounding organs, and then ask the patient to drink warm water 500ml, take a seat or standing position, move the probe, in the stomach projection area
