[Potentialities of high field magnetic resonance tomography in preoperative staging of gastric cancer].
An analysis of results of magnetic resonance tomography (MRT) of the stomach of 80 patients has shown that a complex examination with morphological verification had diagnosed gastric cancer in 60 of them. The technique of fulfilling MRT of the stomach was optimized, the main symptoms of gastric cancer were specified. The sensitivity of preoperative assessment of spread of gastric cancer on MRT was 82%, specificity -78%. The sensitivity of detection of the lymph nodes infiltrated with the tumor in MRT was 82%, specificity--84%. The general diagnostic informative value of MRT in gastric cancer was as follows: sensitivity--93%, specificity--86.6%, accuracy--92%.
