NECROSIS
After CH‐EUS MASTER was constructed, it worked with the main engine of EUS (Figure Real‐time use of CH‐EUS MASTER. (A) CH‐EUS MASTER worked with the main engine of EUS, and placed side by side with the original screen, achieving real‐time pancreatic mass capture and segmentation, benign and malignant pancreatic mass identification based on time‐intensity curve analysis and guiding EUS‐FNA. (B) Time–intensity curves (TICs) of regions of interest (ROIs) drawn by CH‐EUS MASTER. In the right panel, the green box indicates the relatively normal parenchymal region (ROI 2), and the red circle indicates the outline of the pancreatic mass (ROI 1), which has been segmented to subregions (ROI 1 N) by blue boxes. Corresponding TICs of ROI 1 N (red lines) and ROI 2 (green lines) are presented in the left panel, which also shows the confidence and the diagnosis of cancerous or noncancerous. (C) Thermogram of the pancreatic mass region according to the time–intensity curves guiding EUS‐FNA. Different color indicates different lesion depending on CH‐EUS MASTER's judgment. Red indicates cancerous, blue indicates noncancerous, and gray indicates necrosis.
