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).
FDA Clears Controlled Contrast Delivery Method for Ultrasound Imaging of Fallopian Tubes
September 9th 2024Facilitating natural contrast delivery through an intrauterine catheter, FemChec can be utilized for ultrasound assessment of fallopian tubes and may provide diagnostic confirmation for an emerging non-surgical option for permanent birth control.
Study Assesses Lung CT-Based AI Models for Predicting Interstitial Lung Abnormality
September 6th 2024A machine-learning-based model demonstrated an 87 percent area under the curve and a 90 percent specificity rate for predicting interstitial lung abnormality on CT scans, according to new research.
What a Prospective CT Study Reveals About Adjunctive AI for Triage of Intracranial Hemorrhages
September 4th 2024Adjunctive AI showed no difference in accuracy than unassisted radiologists for intracranial hemorrhage (ICH) detection and had a slightly longer mean report turnaround time for ICH-positive cases, according to newly published prospective research.
