【摘要】 本文对23例胃粘膜点状糜烂和5例胃粘膜片状糜烂进行了病理和X线表现的对比研究。点状糜烂病灶均为多发,呈暗红色点状凹陷,其形状为圆形或长圆形,糜烂周围多有水肿粘膜隆起。片状糜烂为一片暗红色低下区,轻度高低不平,形态常不规则,粘膜表面正常,胃小沟、胃小区结构消失。胃X线双重造影片显示:前者为直径2～3mm的点状龛影,周围包绕一透亮圈,即所谓“靶样”病灶;后者为不规则形的片状密度增高区。文中讨论了X线显示技术、鉴别诊断及临床意义。更多还原

【Abstract】 Comparative radiographical and pathological studies were carried out in 23 cases with gastric mucosal pin-point erosions and 5 cases with gastric mucosal patchy erosions. Pathologically, pin-point erosions were dot-like, dark red, round or oval depressions, surrounded by elevated zone of edema. The lesions were multiple in all the cases. Patchy erosions were irregular, dark red, unevenly depressed areas without gastric sulcus or area gastrica. On high quality double contrast examination, the pin-point erosions were shown as minute dots of barium, 2-3 mm in diameter, surrounded by radiolucent halo (so-called "target lesions"). The patchy erosions appeared as irregular areas of barium collection.The clinical significance, differential diagnosis and technique of demonstration are discussed.更多还原
