An AP lordotic chest x-ray is performed to evaluate what part of the lungs?

An AP lordotic chest x-ray is specifically designed to enhance the visualization of the apices, which are the uppermost portions of the lungs. This particular view is used when there is a suspicion of pathology in the apices, such as tuberculosis, cancer, or other conditions that may affect this area. The lordotic position helps to project the apices above the clavicles, reducing obstructions that may obscure these regions in a standard chest x-ray.

In contrast, the other regions of the lungs, such as the lower lobes, middle lobes, and bases, are not the primary focus of this specific view. A standard chest x-ray in a supine or upright position is typically used to evaluate those areas more effectively.
