Combining Biomarkers (AFP AFP-L3 and PIVKA-II) and Image Tools for Early Detection of Hepatocellular Carcinoma
In this study, three biomarkers tests (AFP, AFP-L3 and PIVKA-II) and abdominal sonography or CT scans are performed every 6 months to detect hepatocellular carcinoma (HCC) early in patients with cirrhosis, a high-risk group of HCC. The aim of this study is to confirm the early HCC diagnosis rate in …

Assessment of Paravalvular Leak After TAVI by Hemodynamic Measurements and Cardiac MRI
Echocardiography and angiography systematically underestimate paravalvular leakage (PVL) as compared to cardiac MRI. Hemodynamic measurements are used to aid decision making directly after TAVI implantation. Prospective data comparing hemodynamic measurements with cardiac MRI are needed to design an optimal strategy to grade paravalvular leakage peri-operatively in order to optimize TAVI …

HCC Surveillance: Comparison of Abbreviated Non-contrast MRI and Ultrasound Surveillance in Cirrhotic Patients With Suboptimal Ultrasound Visualisation
All international guidelines recommend 6-monthly ultrasound surveillance for patients at risk for liver cancer (hepatocellular carcinoma or HCC), such as patients with cirrhosis. The aim of surveillance is to detect HCC at an early stage when it is still potentially curable. Currently only 4 out of 10 HCCs are detected …

Qualitative and Quantitative Evaluation of Vascular Flows of Radial Ulnar and Interdigital Arterial Trees Under Normal and Pathological Conditions by 3 Tesla MRI
Between 2015 and 2017, several acquisitions were made in 3 patients who received facial allotransplantation, and the team recently developed a flow MRI protocol dedicated to the study of arterial trees in the hand. The main objective is to measure vascular flows of radial, ulnar and interdigital arterial trees in …
