BACKGROUND MR relaxometry has been extensively studied in the field of cardiac diseases, but its contribution to liver imaging is unclear. We aimed to compare liver and spleen T1 mapping, T2 mapping, and diffusion-weighted MR imaging (DWI) for assessing the diagnosis and severity of cirrhosis. METHODS We prospectively included 129 patients with normal(More)
OBJECTIVES The aim of this study was to compare survival between radiofrequency ablation (RFA) and surgical resection (SR) in patients with hepatocellular carcinoma (HCC) within Milan criteria. METHODS From January 2004 to December 2013 we consecutively and retrospectively included all patients with first occurrence of HCC within Milan criteria receiving(More)
To evaluate the efficacy of selective arterial embolization (SAE) of angiomyolipomas based on the percentage volume reduction after embolization and to identify predictive factors of volume decrease. Patients receiving prophylactic SAE of renal angiomyolipomas were included retrospectively over 3 years. The volume change after SAE and haemorrhagic or(More)
BACKGROUND Elastography is a promising non-invasive approach for assessing liver fibrosis. We assessed diagnostic performances of liver and spleen stiffness using supersonic shear imaging for diagnosing cirrhosis severity and oesophageal varices. METHODS 401 consecutive cirrhotic patients were prospectively enrolled from November 2012 to March 2014. All(More)
BACKGROUND & AIMS The primary aim of this study was to compare the rate of global radiofrequency ablation (RFA) failure between monopolar RFA (MonoRFA) vs. no-touch multi-bipolar RFA (NTmbpRFA) for small hepatocellular carcinoma (HCC) ⩽5cm in cirrhotic patients. METHODS A total of 362 cirrhotic patients were included retrospectively across four French(More)
PURPOSE To propose a postprocessing technique that measures tumor surface with insufficient ablative margins (≤ 5 mm) on magnetic resonance (MR) imaging to predict local tumor progression (LTP) following radiofrequency (RF) ablation. MATERIALS AND METHODS A diagnostic method is proposed based on measurement of tumor surface with a margin ≤ 5 mm on MR(More)
OBJECTIVES This study sought to assess the mid-term efficacy of magnetic resonance-guided high-intensity focused ultrasound (MRgFUS) (Sonalleve system) for uterine fibroids. METHODS We retrospectively included patients treated by MRgFUS controlled by real-time MR-thermometry. Clinical efficacy was defined as the minimum reduction of ten points in the(More)
BACKGROUND & AIMS To compare treatment failure and survival associated with ultrasound-guided radiofrequency ablation (RFA) and trans-arterial chemoembolization (TACE) for early-stage HCC in Child-Pugh A cirrhosis patients. METHODS 122 cirrhotic patients (RFA: 61; TACE: 61) were well matched according to cirrhosis severity; tumor size and serum(More)
BACKGROUND The aim of this study was to evaluate the effectiveness of sunitinib in patients with progressive radioiodine refractory (RAIR) thyroid cancer (TC). MATERIALS AND METHODS A multicentric retrospective analysis was performed of patients treated in six TUmeurs THYroïdiennes REFractaires participating centers. All patients with progressive RAIR TC(More)
