Core Tip

Core Tip: This study developed a machine learning model using clinical indicators and spectral computed tomography (CT) imaging parameters to preoperatively predict lymphovascular and perineural invasive risk in gastric cancer patients. The model combining CT staging, extramural vein invasive based on CT, and quantitative spectral CT measures had high accuracy for noninvasive prediction of these important histological features.
