Study Says Contrast-Enhanced Mammography Offers Comparable Breast Cancer Detection to MRI
Adjunctive Brain Volume Quantification Tool for MRI Gets FDA Clearance
Noting that initial imaging sensitivity is a key factor in cost-effectiveness for patients who do not require acute treatment for dizziness, researchers found that specialized MRI (including multiplanar high-resolution DWI) provided the most benefit in a comparative trial of neuroimaging modalities.
Emphasizing factors such as tumor size, serum neutrophil count and arterial phase hyperenhancement proportion on MRI, a new diagnostic model outperformed eight staging systems for predicting advanced recurrence of hepatocellular carcinoma after liver resection.
Ultrasound and MRI findings from a new study suggest that greater carotid atherosclerosis and elevated white matter hyperintensities among women with the APOEe4 genotype, a strong risk factor for Alzheimer’s disease, are associated with increased PTSD symptoms in midlife women.
