When referring a patient for a CT scan, which of the following statements is incorrect?

The correct choice highlights a common misunderstanding regarding the protocols for patient referrals for CT scans. Making a scanning appliance prior to the appointment is not a requirement when a patient is referred for a CT scan. Instead, the purpose of a CT scan is often to get a high-resolution imaging of the area of interest, and the scan can be conducted without any additional preparatory steps like creating a scanning appliance.

In a typical clinical scenario, the focus would be on capturing the necessary anatomical details through the imaging process itself. Other options build upon appropriate practices, such as sending a patient to a medical imaging center with specific instructions or opting for an in-office Cone Beam CT, which are standard procedures that do not require the creation of any appliance prior to imaging. Therefore, the statement about needing to create a scanning appliance is not aligned with standard practices regarding patient referrals for imaging.
