Diagnostic performance of imaging in deposition arthropathies and Charcot foot

	Plain Radiography	Ultrasonography	Tomography—DECT	Magnetic Resonance
Gout	CG: S 31%–SP 93% [15]	DC: S 83%–SP 76% [21] CG: S 48%–SP 96% [22]	Dx: S 78–100%–SP 89–100% [24]	Soft tissue [14]
CPPD	CDC: S 60%–SP 96% [16, 17]	Ps-DC: S 97.6%–SP 50.8% [39] Dx: S 81–88%–SP 59–92% [17]	Dx: S 78–100%–SP 94% [17]	Soft tissue [14]
Hydroxyapatite	High sensitivity [25]	Rotator cuff: S 98%–SP 94% [25]	More sensitive than the Rx [25]	S 65%–SP 58% [26] HD-SWI: S 98%–SP 96% [27]
Neuropathic arthropathy	S and SP < 50% [18, 19]	Complement study [18]	CNA: Preoperative. [18]	S 90%–SP 79% [18]
