Elements Contrast Clearance Analysis

About Elements Contrast Clearance Analysis

Brainlab's Elements Contrast Clearance Analysis is an MRI-based methodology designed to differentiate regions of contrast clearance and accumulation in brain tumor datasets. This high-resolution analysis provides additional insights to support ongoing assessment and decision-making in clinical specialties such as radiosurgery, radiation oncology, neurosurgery, neuro-oncology, and neuroradiology. The process involves acquiring two standard 3D T1-weighted MRIs, one approximately 5 minutes and another 60 to 105 minutes after the injection of a standard dose of contrast agent. The first series is subtracted from the second to generate volumetric maps that distinguish regions of contrast clearance (depicted in blue) from contrast accumulation (depicted in red). These results enable clinicians to assess radiation effects versus tumor regrowth, facilitating more informed decisions for initial and follow-up treatments.
