Thyroid PET-CT-MRI Example of a 55 year old female with thyroid cancer. A head and neck PET-CT combined with a head and neck Tl-weighted MRI. Using the Hermes automatic co-registration algorithm, the MRI was aligned with the CT and displayed in fusion mode with the PET. Automatic lesion segmentation was performed on the PET to calculate the mean SUV in the lesion, max SUV and peak SUV. As a result of the registration, the volume segmentation can also be seen overlaid on the MRI.
