VerteNet hybrid CNN Transformer improves DXA scan landmark localization

Researchers have developed VerteNet, a hybrid CNN-Transformer model designed to accurately pinpoint vertebral landmarks in lateral spine DXA scans. This deep learning framework addresses challenges posed by low-contrast and artifact-prone images, which often make manual annotation difficult and time-consuming. VerteNet demonstrated superior localization accuracy, achieving a normalized mean error of 4.92 pixels and a median error of 2.35 pixels across scans from four different models. The system also showed high accuracy in detecting abdominal aorta crops and improved inter-reader agreement for clinical analyses. AI
