To evaluate the diagnostic utility of two convolutional neural networks (CNNs) for severity staging anterior cruciate ligament (ACL) injuries. In this retrospective study, 1243 knee MR images (1008 intact, 18 partially torn, 77 fully and 140 reconstructed ACLs) from 224 patients (mean age, 47 years ± 14 [standard deviation]; 54% women) were analyzed. The MRI examinations performed between 2011 2014. A modified scoring metric was used. Classification ACL injuries using deep learning involved...

Viscoelasticity of soft tissue is often related to pathology, and therefore, has become an important diagnostic indicator in the clinical assessment suspect tissue. Surgeons, particularly within head neck subsites, typically use palpation techniques for intra-operative tumor detection. This detection method, however, highly subjective fails detect small or deep abnormalities. Vibroacoustography (VA) similar methods have previously been used distinguish with high-contrast, but a firm...

Osteoarthritis (OA) develops through heterogenous pathophysiologic pathways. As a result, no regulatory agency approved disease modifying OA drugs are available to date. Stratifying knees into MRI-based morphological phenotypes may provide insight predicting future incidence, leading improved inclusion criteria and efficacy of therapeutics. We trained convolutional neural networks classify bone, meniscus/cartilage, inflammatory, hypertrophy in knee MRIs from participants the Initiative (n =...
