Question

Quizplus · Accepted Answer

The tangential, inferosuperior carpal canal wrist projection is specifically designed to demonstrate the carpal canal, which runs through the wrist, so choice B is correct. Choice A may occur if the pisiform bone is not placed directly over the hamulus of the hamate bone or if the incident angle is not accurate. Choice C is not a desired outcome, as elongating the carpal bones may obscure important details. Choice D should not be visible on this projection.
