What is the recommended cassette size for the internal rotation of the shoulder?

The recommended cassette size for the internal rotation of the shoulder is 10" x 12". This size is appropriate because it allows for adequate imaging of the shoulder joint while minimizing unnecessary exposure to surrounding tissues. The 10" x 12" cassette facilitates proper centering and positioning, capturing a clear and detailed view of the shoulder structures during the internal rotation positioning.

Using this cassette size helps healthcare professionals achieve optimal visualization of critical anatomy, which is essential for accurate diagnosis and treatment planning. Larger cassettes might not provide additional benefit in this specific projection and could lead to an increased radiation dose without enhancing diagnostic quality.

In summary, the 10" x 12" size is preferred for shoulder internal rotation because it strikes a good balance between imaging quality, patient safety, and ease of positioning.
