The aim of this study was to evaluate a handheld vacuum-assisted device for magnetic resonance imaging (MRI)-guided breast biopsy. In 47 patients, a total of 47 suspicious breast lesions (mean maximum diameter 9 mm) seen with MRI (no suspicious changes on breast ultrasound or mammography) were sampled using a 10-gauge vacuum-assisted breast biopsy (VAB)(More)
CD4+CD25+ T regulatory cells may play a role in the different clinical presentations of chronic hepatitis C virus (HCV) infection by suppressing CD4+ T cell responses. Peripheral CD4+CD25+ T cells from chronic HCV carriers with normal and abnormal alanine aminotransferase (ALT) were analysed for specificity and effect on HCV-specific CD4+ T cell reactivity(More)
PURPOSE To evaluate, with high-field-strength diffusion-tensor (DT) magnetic resonance (MR) imaging, the axonal architecture of the optic nerves and optic radiations in patients with glaucoma and determine whether DT MR imaging-derived parameters correlate with disease severity. MATERIALS AND METHODS The study was approved by the institutional review(More)
The purpose of this study was to retrospectively determine the safety and effectiveness of percutaneous cryoablation, monitored with computed tomography (CT) and ultrasonographic (US) guidance, for the treatment of hepatocellular carcinoma (HCC). Four patients with small HCCs underwent one percutaneous cryoablation treatment session monitored with CT and US(More)
Acute foot shock stress elicits a selective and time-dependent increase of neuroactive steroid (pregnenolone, progesterone, allotetrahydrodeoxycorticosterone) concentrations in rat brain cortex, accompanied by a marked increase of plasma corticosterone. The brain cortical neuroactive steroid levels peaked between 10 and 30 min poststress and returned to(More)
This study was done to compare percutaneous laser ablation (PLA) and radiofrequency thermoablation (RFA) for the treatment of hepatocellular carcinoma (HCC) ≤4 cm, in patients with liver cirrhosis. Thirty patients with single HCC ≤4 cm in diameter were randomly assigned to one of two treatments: 15 patients were treated with PLA, using a multifibre system(More)
We wanted to determine whether liver contrast-enhanced ultrasound (CEUS)-derived peak signal intensity (PSI) and peak signal intensity/time (PIT) predict liver fibrosis in chronic hepatitis C (CHC). Forty-nine patients with CHC (METAVIR classification) and 10 control subjects were included in the study. After a bolus of 2.4 mL SonoVue (Bracco Imaging,(More)
PURPOSE To evaluate in vivo the efficacy of a newly developed breast radiofrequency (RF) ablation system in human small invasive breast carcinomas in terms of induction of complete tumor necrosis, reproducibility of ablation lesion size and shape, and cosmetic outcome. MATERIALS AND METHODS This study had institutional review board approval, and written(More)
PURPOSE To analyze in vivo the diffusion tensor magnetic resonance imaging (DT-MRI) properties of the intraorbital optic nerve at two different levels: Proximal to the optic nerve head (ONH) and distal to the ONH at the level of the orbital apex in glaucoma patients. METHODS Twenty-four patients with primary open-angle glaucoma were examined. The(More)
OBJECTIVES To correlate diffusion-tensor imaging (DTI) of the optic nerve with morphological indices obtained by scanning laser polarimetry (GDx-VCC); confocal scanning laser ophthalmoscopy (Heidelberg III retinal tomograph; HRT-III) and optical coherence tomography (Stratus OCT). METHODS Thirty-six subjects (12 with no eye disease and 24 with(More)
