Purpose: Compare the difference of ADC in esophageal cancer with different pathological type, determine the role of ADCs in differentiating the pathological type. Materials and Methods: Thiryt-nine patients were examined with SS-EPI DWI sequences at 1.5T MR scanner, 2NEX and breath-hold techniques were employed. To calculate the ADCs of esophageal cancer obtained with two motion-probing gradients (b=0 and b=500sec/mm2). To compare the difference of ADCs in esophageal cancer with different pathological type grouped by the pathology test after operation or biopsy, Results: There was no statistical difference between two type pathological differentiation (p>0.5).
