CAMRT Radiography Practice Exam 2025 – Comprehensive Test Prep

The best demonstration of the cuboid bone on an oblique foot X-ray can be attributed to the positioning of the foot during the imaging process. In an oblique view, the foot is rotated laterally, which helps to show the cuboid in its anatomical position and allows for a clearer view of its relationship with the associated tarsal bones, particularly the fifth metatarsal and the lateral aspect of the foot.

This positioning minimizes superimposition of the other tarsal bones, allowing radiologists and physicians to better assess fractures or other pathologies affecting the cuboid.

The navicular, though also visible on oblique views, is not as prominently demonstrated as the cuboid, since its positioning on the medial side of the foot does not take full advantage of the oblique angle. Similarly, the talus and calcaneus, being more centrally located and situated at different angles within the foot, are not as well isolated in this particular view. The oblique foot X-ray is specifically designed to enhance the visualization of the cuboid bone, making it a key focus of this imaging technique.
