The PA Axial Caldwell for sinuses would be used to best demonstrate which sinuses? 1. Ethmoid sinuses 2. Sphenoid sinuses 3. Maxillary Sinuses 4. Frontal sinuses

PA Esophagus x-ray shows the entire esophagus shifted to the RIGHT of the spine with the spine also curved to the left. What was the ERROR?

Which of the following statements is NOT TRUE about an SMV sinus projection?

A lateral skull projection was taken with the top of the patient’s head tilted toward the IR. What error will be demonstrated on the image?

An AP Waters projection can be distinguished from a PA Waters projection because the AP projection demonstrates: 1. greater orbital magnification 2. less distance from the lateral orbital rims to the lateral cranial borders 3. the petrous ridges superior to the maxillary sinuses 4. less resolution in the nasal region

For an accurate PA Axial Skull projection (Caldwell method), the: 1. midsagittal plane is aligned perpendicular to the IR 2. central ray is angled 15 degrees caudally 3. OML is aligned perpendicular to the IR 4. central ray is centered to the acanthion

The open-mouth PA Waters for Sinuses is used to visualize which sinus(es) best? (1) Frontal (2) Ethmoid (3) Maxillary (4) Sphenoid

Which of the following skull positions would BEST demonstrate the sella turcica in profile?
