PURPOSE To perform a meta-analysis of all available studies of the diagnostic performance of diffusion-weighted magnetic resonance imaging (DW-MRI) in patients with hepatic metastases. METHODS Databases including MEDLINE and EMBASE were searched for relevant original articles published from January 2000 to February 2012. We determined sensitivities and(More)
PURPOSE The technical challenges that have prevented routine proton magnetic resonance spectroscopic imaging (1H MRSI) examinations of the breast include insufficient spatial resolution, increased difficulties in shimming compared to the brain, and strong lipid contamination at short echo time (TE) at1.5T. The authors investigated the feasibility of high(More)
OBJECTIVE To prospectively evaluate the diagnostic efficacy of conventional ultrasound (US), contrast-enhanced US (CEUS), the combined use of two modalities, and magnetic resonance imaging (MRI) in the differentiation of focal solid breast lesions. MATERIALS AND METHODS 61 patients with BI-RADS category 3-5 breast lesions detected at conventional US(More)
GOALS To evaluate the overall diagnostic accuracy of magnetic resonance imaging (MRI) in assessing the activity of Crohn's disease (CD) in the small bowel. BACKGROUND Cross-sectional imaging techniques are playing an increasing role in the evaluation of suspected CD. Advantages of MRI include a lack of ionizing radiation, the ability to provide dynamic(More)
BACKGROUND AND AIM The purpose of this study was to perform a meta-analysis of all available studies of the diagnostic performance of diffusion-weighted imaging (DWI) in the detection of hepatocellular carcinoma (HCC) in patients with chronic liver disease. METHODS Databases including MEDLINE and EMBASE were searched for relevant original articles(More)
RATIONALE AND OBJECTIVES To evaluate the ability of diffusion-weighted magnetic resonance imaging (DWI) in differentiating malignant thyroid nodules from benign lesions with a meta-analysis. MATERIALS AND METHODS Articles in English and Chinese language relating to the accuracy of DWI for this utility were retrieved. Pooled estimation and subgroup(More)
OBJECTIVES To assess the diagnostic value of pulmonary embolism (PE) detection and characterization through quantitative iodine-based material decomposition images with spectral computed tomography (CT) imaging. MATERIALS AND METHODS Fifty-three patients underwent CT pulmonary angiography (CTPA) with spectral imaging mode with the simultaneous acquisition(More)
BACKGROUND To compare the diagnostic capability of diffusion-weighted magnetic resonance imaging (DWI) and (18)F-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) in the N stage assessment in patients with non-small-cell lung cancer. METHODS We performed a meta-analysis of all available studies of the diagnostic(More)
Clinical evidence regarding the value of MRI for therapy responses assessment in breast cancer is increasing. The objective of this study is to compare the diagnostic capability of diffusion-weighted MR imaging (DW-MRI) and contrast-enhanced MR imaging (CE-MRI) to evaluate and predict pathological response in breast cancer patients receiving neoadjuvant(More)
BACKGROUND To compare three different curve-fitting methods for intravoxel incoherent motion (IVIM) analysis in breast cancer. METHODS Diffusion-weighted imaging was acquired in 30 patients with breast cancer using seven b-values (0-800 s/mm(2) ). Three curve-fitting methods were used for biexponential IVIM analysis: a. Direct estimation of D (diffusion(More)
