Multiple Choice

Which of the following best describes the AP axial lordotic position in anatomical imaging?

The patient lies prone with the central ray directed perpendicular to the image receptor.

The patient stands facing the image receptor with arms raised above the head.

The patient sits with the central ray directed caudad to the lumbar spine.

The patient stands with their back arched and shoulders against the image receptor, with the central ray angled cephalad.

Verified step by step guidance

Step 1: Understand the term 'AP axial lordotic position' in anatomical imaging. This position is used to obtain a clear view of specific anatomical structures, such as the apex of the lungs, by reducing superimposition of surrounding tissues.

Step 2: Break down the components of the term: 'AP' refers to anteroposterior, meaning the central ray travels from the front (anterior) to the back (posterior) of the body. 'Axial' indicates that the central ray is angled, and 'lordotic' refers to the arched position of the spine.

Step 3: Analyze the correct description of the AP axial lordotic position. The patient stands with their back arched, shoulders against the image receptor, and the central ray angled cephalad (toward the head). This position helps project the clavicles above the lung apices for better visualization.

Step 4: Compare the incorrect options provided in the problem. For example, lying prone with a perpendicular central ray or sitting with a caudad-directed ray does not match the AP axial lordotic position. Similarly, standing facing the image receptor with arms raised is not consistent with the described position.

Step 5: Confirm that the correct answer aligns with the anatomical imaging technique described. The AP axial lordotic position is specifically designed to optimize imaging of the lung apices and reduce interference from surrounding structures.
