Diagnostic Performance of a Novel Ferumoxytol-Enhanced Magnetic Resonance Angiography/ Venography on Panvascular Disease

The goal of this observational study is to test the diagnostic performance of ferumoxytol-enhanced magnetic resonance angiography/ venography（FE-MRA/MRV） on panvascular disease. The main questions it aims to answer are: 1. How about the imaging quality of FE-MRA/MRV for panvascular disease? 2. What is the diagnostic performance of FE-MRA/MRV for panvascular disease? Participants will be divided into two groups based on their symptoms, body signs or laboratory examinations. Participants who suspected with multisite atherosclerotic diseases like coronary artery disease accompany with renal artery stenosis or peripheral arterial disease will be recruited in multisite artery disease (MAD) group. While participants who suspected with venous thromboembolism (VTE) like pulmonary embolism or deep vein thrombosis will be recruited in VTE group. Participants in MAD group will take both FE-MRA and percutaneous selective angiography measurements of coronary, renal, or lower extremity artery, while participant in VTE group need to do pulmonary artery FE-MRA and computed tomography pulmonary angiography (CTPA), lower extremity vein FE-MRV and ultrasonography.
