Texture analysis and gastric cancer

Study (ref.)	Year	Country	Type of study	No. of patients	ROI selection	CE-MDCT phase	Reference standard	Texture features	Key message
Ba-Ssalamah et al [59]	2013	Austria	Retrospective	47	Single slice	Arterial; venous	Biopsy	2nd order statistics	Texture analysis can differentiate histological subtypes
Giganti et al [62]	2016	Italy	Retrospective	56	Whole tumour	Late arterial	Radical resection	1st and 2nd order statistics	Texture analysis reflects tumour aggressiveness and is related to prognosis
Yoon et al [63]	2016	Korea	Retrospective	26	Single slice	Venous	Biopsy	2nd order statistics	Texture features are associated with better survival in HER2-positive patients receiving trastuzumab
Giganti et al [61]	2017	Italy	Retrospective	34	Whole tumour	Late arterial	Radical resection	1st and 2nd order statistics	Texture analysis provides important information on the response rate to neoadjuvant therapy
Liu et al [60]	2017	China	Retrospective	107	Single slice	Arterial; venous	Radical resection	1st and 2nd order statistics	Texture parameters can predict the degree of differentiation, Lauren classification and vascular invasion
