Imaging Gastrointestinal Stromal Tumors
April 20, 2021 | Terry Sharrer
“This study [from researchers at University of Tokyo] aimed to investigate whether NIR-HSI [near-infrared hyperspectral imaging] is suitable for distinguishing deep SMT [submucosal tumor] lesions. In this study, 12 gastric GIST [gastrointestinal stromal tumor] lesions were surgically resected and imaged with an NIR hyperspectral camera from the aspect of the mucosal surface. Thus, the images were obtained ex-vivo. . . . Although 7 specimens had a mucosal layer (thickness 0.4–2.5 mm) covering the GIST lesion, NIR-HSI analysis by machine learning showed normal and GIST regions as color-coded areas. The specificity, sensitivity, and accuracy of the results were 73.0%, 91.3%, and 86.1%, respectively. MORE
