3T MRI enhances knee osteoarthritis management
3T MRI enhances knee osteoarthritis management
An exam that combines 3T MR imaging with clinical assessment could speed up the management of patients with suspected degenerative arthritis of the knee. Disease biomarkers could be identified in half the time-or less-than is currently possible, according to University of California, San Francisco researchers.
Dr. Sapna Jain and colleagues prospectively assessed 20 patients with knee osteoarthritis and 20 age-matched controls who underwent 3T MRI at baseline and at three, six, and 12 months. The study correlated eight imaging abnormalities of the tibiofemoral compartment with three clinical parameters for the assessment of pain and mobility. The investigators found statistical-ly significant changes in the knees of osteoarthritis patients associated with clinical findings throughout the follow-up period. These changes, however, were mostly absent in normal controls. Jain presented these findings at the 2007 RSNA meeting.
MRI or Ultrasound for Evaluating Pelvic Endometriosis?: Seven Takeaways from a New Literature Review
September 13th 2024While noting the strength of MRI for complete staging of disease and ultrasound’s ability to provide local disease characterization, the authors of a new literature review suggest the two modalities offer comparable results for diagnosing pelvic endometriosis.
Diffusion-Weighted MRI and Neoadjuvant Chemotherapy for Rectal Cancer: What New Research Reveals
September 3rd 2024In a comparison of imaging assessments to gauge the effectiveness of neoadjuvant chemotherapy for rectal adenocarcinoma, researchers found the combination of diffusion-weighted imaging and MR tumor regression grading had a 90 percent area under the curve (AUC) and a negative predictive value (NPV) of 93 percent.
FDA Expands Clearance of MRI-Guided AI Platform for Deep Brain Stimulation and Lesioning Techniques
September 3rd 2024Utilizing a new machine learning model, the OptimMRI software may improve radiosurgery applications and lesioning techniques such as MRI-guided focused ultrasound through enhanced targeting of the inferolateral part of the ventral intermediate nucleus (VIM).
