Magnetic resonance-guided high-intensity focused ultrasound for uterine fibroids: Mid-term outcomes of 36 patients treated with the Sonalleve system.

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 Transformed Symptom Severity Score (tSSS) without additional treatment.

Acoustic Radiation Force Impulse (ARFI) and Transient Elastography (TE) for evaluation of liver fibrosis in HIV-HCV co-infected patients.

Background: Transient elastography (TE) is widely used for non-invasive assessment of liver fibrosis in HIV-HCV co-infected patients. TE, however, cannot determine liver morphology. Acoustic radiation force impulse (ARFI) imaging is a novel procedure enabling assessment of liver fibrosis during a conventional ultrasonographic examination.

Evaluation of liver tumors using acoustic radiation force impulse elastography and correlation with histologic data.

Objectives: Acoustic radiation force impulse (ARFI) technology represents an innovative method for the quantification of tissue elasticity. The aims of this study were to evaluate elasticity by ARFI in both liver tumors and background liver tissue and to compare ARFI measurements with histologic data in liver tumors and background liver.

Methods: Seventy-nine tumors were prospectively studied: 43 benign and 36 malignant.
