Crystalline-induced arthropathies impose substantial morbidity but can be challenging to diagnose, especially in early phases. The most common crystalline arthropathies are gout (monosodium urate deposition), calcium pyrophosphate dihydrate deposition, and hydroxyapatite deposition disease. Computed tomography (CT) and MR imaging provide 3-dimensional information on osseous structures, periarticular soft tissue, and tophi with superior spatial resolution. Dual-source CT (dual-energy CT [DECT]) offers the further advantage of selectively identifying crystalline deposits. CT, MR imaging, and DECT can be of value in problematic cases and can potentially be used for disease monitoring. Further research is necessary to elucidate their added value.
