Dynamic MR imaging for extraserosal invasion of advanced gastric cancer.
Dynamic magnetic resonance (MR) images in 37 patients with gastric cancers were obtained by a two-dimensional fast multiplanar spoiled gradient technique. The degree of tumor invasion was classified into four grades regarding a low-intensity band between the stomach and surrounding fat. Advanced gastric cancer was strongly enhanced, appearing as a thickened wall, by the contrast medium during the early to delayed phases of dynamic studies. The extent of invasion of the adjacent organs was diagnosed by the difference in enhancement between the tumor and the parenchyma. The sensitivity of extraserosal invasion was 93%. Dynamic MR diagnosis is useful for evaluating the extent of gastric carcinoma.
