Patients should be fasted the morning of the ultrasound unless it is deemed unsafe to do so (e.g. diabetic patients). On site CT and MRI allows for the scheduling of daily scans. Unsure of which imaging modality is the best fit for your patient? Dr. Freer encourages inquiries to help determine the best (and most cost effective) imaging solution for your patient.
