RadioPathomics Artificial Intelligence Model to Predict Tumor Regression Grading in Locally Advanced Rectal Cancer
The radiopathomics AI system predicts individual tumor regression grading (TRG) category based on each patient's radiopathomics features extracted from the Magnetic Resonance Imaging (MRI) and biopsy images. The predictive power to classify each patient into particular TRG category will be validated in this multicenter, prospective clinical study.

RadioPathomics Artificial Intelligence Model to Predict nCRT Response in Locally Advanced Rectal Cancer
By the system, whether the participants achieve the pathologic complete response (pCR) will be identified based on the radiopathomics features extracted from the pre-nCRT Magnetic Resonance Imaging (MRI) and biopsy images. The predictive power to discriminate the pCR individuals from non-pCR patients, will be validated in this multicenter, prospective clinical …

Radiomics-based Artificial Intelligence System to Predict Neoadjuvant Treatment Response in Rectal Cancer
Previously, the radiomics prediction model has been constructed based on the radiomics features extracted from pretreatment Magnetic Resonance Imaging (MRI) in the training set, and optimized in the external validation set. The predictive power of this radiomics prediction model to discriminate the pathologic complete response (pCR) patients from non-pCR individuals, …

Physiological Changes of the Mitral Annulus After Annuloplasty in Barlow Disease
It is hypothesized that the major mechanism of the valvular insufficiency in Barlow disease is a deformation of the left ventricle and the posterior mitral annulus, causing its aberrant displacement during the systole towards posterior and basal and thus impairing the coaptation of the leaflets. This prospective individual MRI study …

Prospective Trial for the Evaluation of Radiogenomics in Advanced Rectal Cancer
In patients with advanced rectal cancer, molecular subtypes will be identified by preoperative biopsy, CT, MRI / PET radiomics analysis, clinical features, and clinical features will be confirmed and compared. Also, we want to confirm the relationship between these factors and the treatment response after chemoradiotherapy before surgery.
