MR Based Survival Prediction of Glioma Patients Using Artificial Intelligence

This registry aims to collect clinical, molecular and radiologic data including detailed survival data, clinical parameters, molecular pathology (1p/19q codeletion, MGMT methylation, IDH and TERTp mutations, etc) and conventional/advanced/new MR sequences (T1, T1c, T2, FLAIR, ADC, DTI, PWI, etc) of patients with primary gliomas. By leveraging artificial intelligence, this registry …

Risk Stratification of Multicenter Patients With Heart Failure: Clinic, Labortary Test and Cardiovascular Magnetic Resonance Imaging

Heart failure (HF) is the final stage of the heart disease. The prevalence of heart failure continues to rise, but the diagnosis and treatment is not satisfactory. At present, there is no relatively ideal model to predict the adverse cardiovascular events in patients with heart failure and carry out effective …

Ventilation and Perfusion Imaging in Acute Pulmonary Embolism Following Catheter Directed Aspiration Thrombectomy Versus Conservative Therapy Alone: A Pilot Study (VQPE)

Clinical presentation of acute pulmonary embolism (PE) is complex and varied and not uncommonly involves respiratory failure with dyspnea or hypoxia. Patients with persisting signs of respiratory failure despite anticoagulation, may benefit from catheter directed thrombectomy. Additionally, patient who receive thrombectomy are likely to have a lower residual thrombus burden …

Whole-Heart Myocardial Blood Flow Quantification Using MRI

This study hopes to provide significant technical improvement in a Myocardial Blood Flow (MBF) cardiac magnetic resonance (CMR) quantification technique to address challenges and technical limitations for MBF CMR. By developing and validating novel techniques to improve first-pass perfusion (FPP) cardiac MR, we propose to increase diagnostic accuracy by minimizing …

Carotid Revascularization and Medical Management for Asymptomatic Carotid Stenosis Trial - Hemodynamics (CREST-H) (CREST-H)

We aim to determine whether cognitive impairment attributable to cerebral hemodynamic impairment in patients with high-grade asymptomatic carotid artery stenosis is reversible with restoration of flow. To accomplish this aim CREST-H will add on to the NINDS-sponsored CREST-2 trial (parallel, outcome-blinded Phase 3 clinical trials for patients with asymptomatic high-grade …
