OBJECTIVE To evaluate the value of intratumoral vessels and micro-hemorrhage shown in susceptibility weighted imaging (SWI) for grading brain astrocytomas and to analyze the difference between SWI and conventional imaging techniques. METHODS 22 patients with astrocytomas were diagnosed with surgical specimens, 9 of which were grades I-II, and 13 were(More)
OBJECTIVE To study the clinical value of a new MRI compatible percutaneous bone biopsy system. METHODS Twenty-six patients with bone lesions MRI-guided biopsies underwent using a 0.23-T open MR system combined with an iPath-200 optical leading system. RESULTS Of the 26 biopsies, 23 samples were sufficient for histological examination and the(More)
AIM To investigate the usefulness of three-dimensional (3D) fast imaging employing steady state precession (FIESTA) magnetic resonance imaging (MRI) at 3 T in evaluating the intraparotid components of the facial nerve and parotid ducts, and to compare the MRI images with surgical findings. MATERIALS AND METHODS Thirty-one cases of benign parotid tumours(More)
OBJECTIVES To explore the utility of diffusion tensor imaging (DTI) and acoustic radiation force impulse (ARFI) imaging in the diagnosis of parotid tumours. METHODS 51 patients with parotid tumours were examined with DTI on 3.0-T MRI and ARFI imaging on an ultrasound scanner before surgery. Values of apparent diffusion coefficient (ADC), fractional(More)
