The aim of this study was to develop an MRI protocol to evaluate the growth and vascularity of implanted GL261 mouse gliomas on a 7T microimaging system. Both conventional T(1)- and T(2)-weighted imaging and dynamic, contrast-enhanced T(2)*-weighted imaging were performed on 34 mice at different stages of tumor development. MRI measurements of relative cerebral blood volume (rCBV) were compared...

− In many patients, lesions of focal cortical dysplasia (FCD) may go unrecognized by standard radiological analysis. This is due to the fact that identification of many of these malformations on visual inspection of conventional MRI is difficult due to their subtlety and the complexity of the brain’s convolutions. Quantitative MR image processing methods have the potential to help identify lesi...

For the woman with a newly diagnosed early stage breast cancer, the routine use of pre-operative breast MRI (magnetic resonance imaging) is not indicated beyond conventional breast imaging (i.e., mammography with correlation ultrasound as indicated). There is no consistent evidence that a pre-operative breast MRI confers a benefit to the patient by improving clinical outcomes or surgical proced...

This study was carried out to determine the risk of new ischemic events, demonstrated by diffusion weighted magnetic resonance imaging (DW-MRI) in patients undergoing diagnostic conventional cerebral angiogram. MEDLINE, EMBASE, Current Contents, Cochrane Central, Expert Files, and bibliographies included articles were systematically searched identify prospective studies that reported MRI findin...
