T1-weighted MRI identifies signs of multiple sclerosis
Long-standing suspicions about noncontrast T1-weighted MRI's usefulness as a biomarker for multiple sclerosis have been confirmed in a study showing that hyperintense plaques revealed with the technique are associated with brain atrophy, disability, and an advancing course for the disease.
Long-standing suspicions about noncontrast T1-weighted MRI's usefulness as a biomarker for multiple sclerosis have been confirmed in a study showing that hyperintense plaques revealed with the technique are associated with brain atrophy, disability, and an advancing course for the disease.
Dr. Vallabh Janardhan and colleagues at Brigham and Women's Hospital in Boston and State University of New York at Buffalo retrospectively reviewed data from 145 MS patients who underwent unenhanced T1-weighted MRI from July 1995 to June 1999. Ninety-two patients had relapsing-remitting MS, and 49 were diagnosed with secondary-progressive MS. The disease type was unknown in four cases. The investigators found a significant correlation between hyperintense lesions, detected with noncontrast T1-weighted MRI, and secondary-progressive MS (Radiology 2007;244:823-831).
Can Generative AI Facilitate Simulated Contrast Enhancement for Prostate MRI?
January 14th 2025Deep learning synthesis of contrast-enhanced MRI from non-contrast prostate MRI sequences provided an average multiscale structural similarity index of 70 percent with actual contrast-enhanced prostate MRI in external validation testing from newly published research.
Can MRI Have an Impact with Fertility-Sparing Treatments for Endometrial and Cervical Cancers?
January 9th 2025In a literature review that includes insights from recently issued guidelines from multiple European medical societies, researchers discuss the role of magnetic resonance imaging (MRI) in facilitating appropriate patient selection for fertility-sparing treatments to address early-stage endometrial and cervical cancer.
