Numerous radiographic signs have been described to establish benignity of gastric ulcers . Smooth mucosal folds that extend to the edge of the ulcer crater are a reliable indicator of benignity. The smooth nature of the folds must be seen with certainty because nodular radiating folds may indicate an ulcerated malignancy.

Other signs of a benign gastric ulcer are the ulcer collar, Hampton’s line, and the penetration sign. The ulcer collar represents a rim of mucosa along the margin of the ulcer crater that is thickened by submucosal edema. A similar sign, the Hampton’s line, is an extremely narrow, radiolucent line (1-2 mm) that separates the ulcer crater from the gastric lumen. This sign is rarely seen but virtually ensures the benign nature of the ulcer because a tumor mass is not be expected to preserve a thin band of normal mucosa at its margin. The penetration sign is seen when the ulcer crater, viewed in profile, projects beyond the gastric lumen. The single best sign of a benign ulcer is complete healing after a course of conservative medical therapy.

有许多影像征象可以用来描述良性溃疡。光滑粘膜皱壁延展到病灶边缘是良性溃疡的可靠征象。一定要确定粘膜皱壁是光滑的才可确定为良性，因为结节样轮辐状粘膜皱壁也可提示恶性溃疡。
其他良性征象还有溃疡领、汉普顿线和渗透征。溃疡领表示溃疡周围的粘膜下水肿导致粘膜边缘增厚。汉普顿线也差不多，是一个很窄的透亮影（1-2mm），把溃疡和胃腔分隔开。这一征象相对少见，但确实表示良性，因为恶性肿瘤周围不会表现为细长的正常粘膜带。渗透征表示，溃疡侧位观时，溃疡边缘突出胃腔。良性溃疡的最佳征象就是经一段时间的药物保守治疗后，表现为完全痊愈。
