Jiang J, Tyagi N, Tringale K, Crane C, Veeraraghavan H, “Self-supervised 3D anatomy segmentation using self-distilled masked image transformer (SMIT)”, Medical Image Computing and Computer Assisted Interventions. Image foundation model created with self-supervised learning performed through self-distillation using a large cohort of unrelated and curated image sets from multiple disease sites including lung cancers, COVID-19, head and neck cancers, and abdomen cancers. Once pre-trained, the model can be fine-tuned with modest labeled data to different tasks including segmentation on CT, MRI as well as classification.  

Horvat N and Veeraraghavan H (equal), Nahas CSR, Bates DDB, Ferreira FR, Zheng J, Capanu M, Fuqua JL 3rd, Fernandes MC, Sosa RE, Jayaprakasam VS, Cerri GG, Nahas SC, Petkovska I, “Combined artificial intelligence and radiologist model for predicting rectal cancer treatment response from magnetic resonance imaging: an external validation study”, Abdominal Radiology, 2022. Validation of a previously developed radiomics model on an independent and external cohort that also showed ability to increase accuracy of less experienced radiologists to the level of more experienced radiologists by adding radiomics classification as additional information.

Jiang J, Elguindi S, Berry SL, Onochie I, Cervino L, Deasy JO, Veeraraghavan H. “Nested block self-attention multiple resolution residual network for multiorgan segmentation from CT”, Medical Physics, 2022. This model is used for auto segmentation of head and neck organs in the MSK radiotherapy clinic.

Thompson HM, Kim JK, Jimenez-Rodriguez RM, Garcia-Aguilar J, Veeraraghavan H. “Deep-learning based model for identifying tumor in endoscopic images from patients with locally advanced rectal cancer treated with total neoadjuvant chemotherapy”, Diseases of Colon and Rectum, 2022. One of the AI assisted approaches to longitudinally evaluate endoscopy images to improve earlier detection of tumor regrowth on patients placed in watch and wait prior to surgery.

Jiang J and Veeraraghavan H., “One-shot PACS: Patient specific anatomic context and shape prior aware recurrent registration-segmentation of longitudinal thoracic cone-beam CTs. IEEE Transactions on Medical Imaging, 2022. Longitudinal tracking of tumor volume response from difficult to interpret cone-beam CTs. Simultaneous registration also allows deformable dose accumulation to objectively quantify deposited radiation to tumor and tissues during treatment course.
