Dipartimento di Diagnostica per Immagini ed Imaging Molecolare, Radioterapia e Radiologia Interventistica, Fondazione Policlinico Universitario Tor Vergata (PTV), Viale Oxford 81, 00133, Rome, Italy.
Purpose: This study was undertaken to explore the capabilities of an open-configuration, low-field, tilting, magnetic resonance (MR) system for investigating pelvic floor disorders and to compare the results obtained with the patient in the semiorthostatic and supine positions.
Materials And Methods: Eighteen female patients with a diagnosis of pelvic floor disorder (physical examination and conventional defecography) underwent dynamic MR defecography (MRD) with a 0.25-T tilting MR system (G-scan, Esaote).

September 2008
Dipartimento di Diagnostica per Immagini, Imaging Molecolare, Radiologia Interventistica e Terapia Radiante, Policlinico Universitario Tor Vergata (PTV), Viale Oxford 81, 00133, Roma, Italy.
Purpose: The aim of this study was to evaluate a handheld vacuum-assisted device for magnetic resonance imaging (MRI)-guided breast biopsy.
Materials And Methods: 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) device under MRI guidance. Histology of biopsy specimens was compared with final histology after surgery or with follow-up in benign lesions.
