The paper assesses the present-day role of MRI in the diagnosis of gastric cancer. The authors consider the major prerequisites for the main aim of their study to be: 1) a dramatic incidence of diffuse (endophytic) gastric carcinoma, which requires significant correction of today's approaches to its diagnosis and 2) a rather biased and, in the authors' opinion, present-day mainly negative attitude towards MRI of the stomach as a diagnostic method for its tumor lesions. By applying the X-ray-MRI anatomic principle to the comparative study of MRI findings in 50 patients with predominantly gastric intramural carcinoma and in 25 patients without gastric tumors (controls), the authors present their methods for gastric MRI, the MRI semiotics of gastric cancer by concurrently touching upon a variety of problems that characterize the potentialities of MRI of the stomach in the diagnosis of its tumor lesions, including their differential diagnosis. As a result, the authors highly appreciate gastric MRI and consider this method to be included into the diagnostic algorithm of radiation techniques used in the diagnosis of gastric cancer, which should occupy its definite diagnostic place.
本文评估了磁共振成像(MRI)在胃癌诊断中的当前作用。作者认为其研究主要目的的主要前提条件为:1)弥漫性(内生型)胃癌的发病率急剧上升,这需要对当今其诊断方法进行重大修正;2)对于胃MRI作为胃肿瘤病变诊断方法,目前存在相当大的偏见,且作者认为这种态度主要是否定的。通过将X射线 - MRI解剖学原理应用于对50例以胃壁内癌为主的患者和25例无胃肿瘤患者(对照组)的MRI检查结果进行对比研究,作者展示了他们的胃MRI检查方法、胃癌的MRI符号学,同时还涉及了一系列表征胃MRI在胃肿瘤病变诊断中潜力的问题,包括鉴别诊断。结果,作者高度评价胃MRI,并认为该方法应纳入用于胃癌诊断的放射技术诊断算法中,且应占据其明确的诊断地位。
