In relapsing-remitting (RR) multiple sclerosis (MS), conventional magnetic resonance (MR) imaging (MRI) has proved to be a valuable tool to assess the lesion burden and activity over time. However, conventional MRI cannot characterize and quantify the tissue damage within and outside such lesions and only can provide some gross measures reflecting the presence of irreversible tissue damage, suc...

Accurate local staging of prostate cancer is essential for patient management decisions. Conventional and evolving magnetic resonance imaging (MRI) techniques, such as diffusion- weighted imaging, dynamic contrast-enhanced MRI, and MR spectroscopy, are promising techniques in prostate cancer imaging. In this article, we will review the current applications of conventional and ...

BACKGROUND Thin-section oblique axial magnetic resonance imaging (MRI) is useful in staging endometrial and cervical carcinomas but there are no data on its contribution to assessing deep endometriosis. We evaluated the contribution of this MRI technique to diagnosis of uterosacral ligament (USL) endometriosis. METHODS In this retrospective study, two radiologists, who were blinded to the sur...

BACKGROUND Accurate localization of acute ischemic lesions in patients with an acute stroke may aid in understanding the etiology of their stroke and may improve the management of these patients. OBJECTIVE To determine the yield of adding diffusion-weighted magnetic resonance imaging (DWI) to a conventional magnetic resonance imaging (MRI) protocol for acute stroke. DESIGN A prospective coh...

OBJECTIVE To determine the feasibility of using T2 mapping as a quantitative method to longitudinally follow the disease activity in children with Duchenne muscular dystrophy (DMD) who are treated with steroids. MATERIALS AND METHODS ELEVEN BOYS WITH DMD (AGE RANGE: 5-14 years) underwent evaluation with the clinical functional score (CFS), and conventional pelvic MRI and T2 mapping before and...

OBJECTIVES To compare magnetic resonance myocardial perfusion imaging (MRI) with anatomical assessment by multislice computed tomography (MSCT) coronary angiography and conventional coronary angiography. DESIGN AND PATIENTS In this prospective study, 53 patients (60% male, average age 57+/-9 years, 83% intermediate pre-test likelihood) underwent 1.5 T MRI, 64-slice MSCT and conventional coron...

BACKGROUND Patient-specific instrumentation in TKA has the proposed benefits of improving coronal and sagittal alignment and rotation of the components. In contrast, the literature is inconsistent if the use of patient-specific instrumentation improves alignment in comparison to conventional instrumentation. Depending on the manufacturer, patient-specific instrumentation is based on either MRI ...
