Breast Density Assessment Using a 3T MRI System: Comparison among Different Sequences
PURPOSE To compare MRI sequences for breast density measurements on a 3T MRI system using IDEAL (Iterative Decomposition of water and fat with Echo Asymmetry and Least squares estimation) as possible physiology-like reference. MATERIALS AND METHODS MRI examination was performed in 48 consecutive patients (mean age 41, years; range, 35-67 years) on a 3.0T scanner and 46 were included. All (fer...
متن کاملNovel application of T1-weighted BLADE sequences with fat suppression compared to TSE in contrast-enhanced T1-weighted imaging of the neck: cutting-edge images?
PURPOSE To evaluate if the use of BLADE sequences might overcome some limitations of magnetic resonance imaging (MRI) in the extracranial head and neck, which is a diagnostically challenging area with a variety of artifacts and a broad spectrum of potential lesions. MATERIALS AND METHODS After informed consent and Institutional Review Board approval, two different BLADE sequences with (BLADE ...
متن کاملValue of diffusion weighted imaging in the differential diagnosis of benign and malignant breast lesions at 3.0T MRI.
The aim of this study was to investigate the correlation between apparent diffusion coefficients (ADCs), the relative apparent diffusion coefficient (rADC), and the pathological prognostic factor human epidermal growth factor receptor 2 (HER-2) in patients with breast cancer. A total of 64 women with breast cancer underwent breast diffusion-weighted imaging. HER-2 expression was detected in his...
متن کاملMulti-shot Diffusion-Weighted Split-Echo PROPELLER MRI of the Abdomen
Introduction Diffusion-weighted MRI (DWI) provides a non-invasive method for in vivo evaluation of tissue water mobility. Most DWI studies employ single-shot DWEPI techniques which can suffer severe artifacts and image distortion in abdominal imaging applications. Multi-shot TSE-based DW-PROPELLER [1] may overcome these limitations. DW-PROPELLER for brain [2] and abdominal [3] imaging has demon...
متن کاملShould less motion sensitive T2-weighted BLADE TSE replace Cartesian TSE for female pelvic MRI?
OBJECTIVES To prospectively compare the diagnostic performance of a non-Cartesian k-space sampling T2-weighted TSE BLADE sequence with a conventional T2-weighted TSE sequence in female pelvic organs. METHODS Forty-seven patients with sonographically indeterminate adnexal masses or uterine lesions underwent sagittal BLADE and conventional TSE at 1.5 T after glucagon administration. Two radiolo...
