Ex Ablate - Uterine Fibroid Patient Procedure - Treatment Evaluation

Treatment Evaluation

At the end of the MRgFUS procedure, the patient is injected with gadolinium contrast agent and T1w post-contrast MRI scans are performed. These images are used to determine the NPV (Non-Perfused Volume) of the fibroid, which is the volume of tissue that is non-viable (has no blood flow to it). The NPV ratio of a fibroid is defined as the non-perfused tissue volume measured by the T1w post contrast scans, divided by the fibroid volume measured by the T2w images pre treatment.

Famous quotes containing the words evaluation and/or treatment:

    Evaluation is creation: hear it, you creators! Evaluating is itself the most valuable treasure of all that we value. It is only through evaluation that value exists: and without evaluation the nut of existence would be hollow. Hear it, you creators!
    Friedrich Nietzsche (1844–1900)

    If the study of all these sciences, which we have enumerated, should ever bring us to their mutual association and relationship, and teach us the nature of the ties which bind them together, I believe that the diligent treatment of them will forward the objects which we have in view, and that the labor, which otherwise would be fruitless, will be well bestowed.
    Plato (c. 427–347 B.C.)
