Correct answer: D — MRI arthrogram or high-resolution MRI of the hip
The best answer is “MRI arthrogram or high-resolution MRI of the hip”. MRI arthrogram or high-resolution MRI of the hip most directly resolves the diagnostic or staging uncertainty at this point in the pathway; the other investigations answer different questions or have lower yield. The remaining choices—“Plain abdominal radiograph, within a rheumatology pathway”, “Ultrasound of the scrotum”, “DEXA scan as initial test”, “Nerve conduction studies, within a rheumatology pathway”—are credible in related rheumatology presentations, but each addresses a different diagnosis, investigation, treatment sequence or complication and does not fit the decisive findings in this stem.
