Make the optimum treatment decision based on imaging analysis

Elements Contrast Clearance Analysis is an MRI-based methodology for the differentiation of contrast clearance and accumulation regions in brain tumor datasets. The high-resolution analysis results provide additional insights to support you during ongoing assessment and decision-making.

Clinical use & methodology

Developed at Sheba Medical Center in Tel Aviv, Contrast Clearance Analysis serves multiple clinical specialties including radiosurgery, radiation oncology, neurosurgery, neuro-oncology and neuroradiology.

Clinical use

High-resolution Contrast Clearance Analysis results derived from conventional 3D contrast-enhanced MRI data provide additional insights into tumor characteristics. These results enable the ongoing assessment of radiation effects versus tumor re-growth to support you in making the most appropriate decisions for initial and follow-up treatments.

Methodology

The method requires the acquisition of two standard 3D T1-weighted MRIs—one 5 minutes and another 60-105 minutes after injection of a standard dose of contrast agent. The first series is intelligently subtracted from the second for Contrast Clearance Analysis. The analysis results are high-resolution, volumetric maps distinguishing regions of contrast clearance (blue) from contrast accumulation (red).
