Which projection is used to best demonstrate the right axillary border of the ribs?

AP rib projection - LPO
PA rib projection - RPO
AP oblique rib projection - RPO
PA oblique rib projection - LPO

The correct answer is: AP oblique rib projection - RPO

The AP oblique rib projection with right posterior oblique positioning is the optimal choice for demonstrating the right axillary border of the ribs. In this position, the right ribs are angled away from the imaging receptor, allowing for clearer visualization of the posterior ribs and the axillary region. The oblique angling of the patient provides an effective way to separate the right ribs from the surrounding structures, minimizing superimposition and enhancing detail in the area of interest. This projection also facilitates visualization of the intercostal spaces, which can be crucial when assessing for pathologies such as fractures, lesions, or other abnormalities along the axillary border. By positioning the patient in the RPO orientation, the natural curvature of the ribs is also aligned with the imaging receptor, resulting in an improved overall image quality for diagnosing conditions affecting this specific aspect of the ribcage.
