Large-scale esophageal cancer screening through noncontrast computed tomography and artificial intelligence

The absence of accurate, noninvasive, scalable screening tools keeps early esophageal cancer (EC) detection a global health challenge. Although noncontrast computed tomography (NC CT) is widely accessible, the esophagus is a hollow tubular structure prone to collapse and motion a...

An expert-level generalist AI for abdominal CT diagnosis
