To evaluate the usefulness of a texture-based automated quantification system (AQS) for evaluating the extent and interval change of regional disease patterns on initial and follow-up high-resolution computed tomographies (HRCTs) of fibrotic interstitial pneumonia (FIP). Eighty-nine patients with clinically and/or biopsy confirmed usual interstitial(More)
BACKGROUND AND PURPOSE The increased cochlear signal on FLAIR images in patients with acoustic neuroma is explained by an increased concentration of protein in the perilymphatic space. However, there is still debate whether there is a correlation between the increased cochlear FLAIR signal and the degree of hearing disturbance in patients with acoustic(More)
The aim of this study was to determine whether diffusion and perfusion imaging parameters demonstrate different diagnostic values for predicting pseudoprogression between glioblastoma subgroups stratified by O6-mythylguanine-DNA methyltransferase (MGMT) promoter methylation status. We enrolled seventy-five glioblastoma patients that had presented with(More)
BACKGROUND Although fine-needle aspiration (FNA) is a safe and accurate diagnostic procedure for assessing thyroid nodules, it has limitations in diagnosing follicular neoplasms due to its relatively high false-positive rate. The purpose of the present study was to evaluate the diagnostic role of core-needle biopsy (CNB) for thyroid nodules with follicular(More)
To determine the diagnostic superiority of parametric response mapping of apparent diffusion coefficient (ADCPR) for predicting glioblastoma treatment response, compared to single time point measurement. Fifty post-treatment glioblastoma patients were enrolled. ADCPR was calculated from serial apparent diffusion coefficient (ADC) maps acquired before and at(More)
Our study was intended to demonstrate the different signal intensity (SI) pattern of the putamen seen on susceptibility-weighted imaging (SWI) between that of Parkinson's disease (PD) and Parkinsonism-predominant multiple system atrophy (MSA-P), and to correlate it with (18)F-flurodeoxyglucose positron-emission tomography ((18)F-FDG PET). Thirty patients(More)
OBJECTIVE To investigate CT and (18)F-flurodeoxyglucose ((18)F-FDG) positron-emission tomography/CT findings of primary endobronchial marginal zone B-cell lymphoma of the bronchus-associated lymphoid tissue (BALT). MATERIALS AND METHODS From June 2006 through April 2012, seven patients (six female, one male; age range, 21-61 years; mean age, 49 years)(More)
OBJECTIVE To describe computed tomographic (CT) findings of anthracofibrosis involving lung parenchyma. METHODS Retrospectively reviewed CT findings of 34 patients with anthracofibrosis involving lung parenchyma, showing deposition of anthracotic pigmentation with focal fibrotic lesions on histologic examination. RESULTS Types included nodules (41.2%),(More)
OBJECTIVE To investigate the correlation between perfusion- and diffusion-related parameters from intravoxel incoherent motion (IVIM) and those from dynamic contrast-enhanced MR imaging (DCE-MRI) and diffusion-weighted imaging in tumors and normal muscles of the head and neck. MATERIALS AND METHODS We retrospectively enrolled 20 consecutive patients with(More)
BACKGROUND AND PURPOSE Diagnostic test accuracy studies for ultrasonography-guided fine-needle aspiration and ultrasonography-guided core needle biopsy have shown inconclusive results due to their heterogenous study designs. Our aim was to compare the diagnostic accuracy of ultrasonography-guided fine-needle aspiration versus ultrasonography-guided core(More)
