23 cze 2019 · The Z line is an irregular serrated line that demarcates the squamocolumnar mucosal junction. The Z line can sometimes be recognized on double-contrast esophagograms as a thin radiolucent stripe in the distal esophagus with a characteristic zigzag appearance ( Fig. 26-2 ).
This results in the common endoscopic diagnosis of “irregular z-line.” The yield of biopsy of this area to determine the presence of specialized intestinal metaplasia is the subject of this report.
The suggested system consists of three major phases: preprocessing, feature extraction using optimized convolutional neural network (CNN), and classification based on gated recurrent unit (GRU).
