Answer:
b) Zygapophyseal joints well-visualized
Explanation:
In the context of an oblique L-spine radiograph, the zygapophyseal joints should be well-visualized when there is under-rotation. This means that the patient's spine is rotated less than the optimal angle required to fully visualize the zygapophyseal joints. As a result, they may appear overly oblique or lateralized, leading to a clearer visualization of the zygapophyseal joints. This under-rotation can affect the diagnostic quality of the image and may necessitate repeat imaging to obtain a more accurate assessment of the lumbar spine.
