Before the patient is placed in the immobilization device, a MRI technologist with experience giving gadoxetate disodium injections will give the prescribed injection according to the patient's body weight. After the injection is given, a liver SBRT trained radiation therapist will lead the patient to the treatment machine and set them up in the immobilization device as per standard treatments. The same time-of-treatment imaging will be performed, with the hypothesis that the image quality will improve because of the addition of the contrast agent. The contrast agent will only be administered at the first treatment because of the limited data on repeat injections of the drug in humans. Furthermore, for the first treatment when contrast is administered, a radiation oncologist, radiologist, medical physicist, MRI technologist, and three radiation therapists will attend.
