Dual-energy CT-scan is a reproducible and accurate imaging modality for the diagnosis of gout, particularly for tophaceous gout (intra- or extra-articular). It can become a second-line imaging modality of choice in cases of diagnostic doubt, such as ultrasonography.



Background/Purpose: Advanced imaging modalities such as ultrasound (US) and dual-energy CT (DECT) can help diagnose crystalline arthritis. DECT is a highly sensitive and specific modality to detect gout and has not been well studied in pseudogout. We compared the sensitivity of DECT, US, and x-ray (XR) in pseudogout. Dual energy computed tomography (DECT) is a relatively new imaging modality which shows great promise in the diagnosis of gout. It is a good noninvasive alternative to synovial fluid aspiration.

The gout crystals are color coded in green. 2020-09-11 None of the methods described above are sufficiently sensitive or specific for the diagnosis of gout, which relies on the identification of MSU crystals. It is in this setting that dual‐energy CT (DECT) offers the unique capability for the non‐invasive detection of these crystals earlier in the course of the disease. Dual‐Energy CT (DECT) 2013-10-17 In an effort to maximize the specificity and sensitivity of dual-energy CT, it is crucial that practicing radiologists recognize artifacts when utilizing dual-energy CT gout protocols. These artifacts are recognizable as mapping of urate color into nails and nail beds, skin calluses, approximated areas of skin (eg, between fingers), arteries, and image areas affected by motion or beam 2011-11-29 2016-09-21 2011-11-04 2015-09-01 2020-01-17 cal composition of uric acid by dual energy CT (DECT) scans may provide a useful imaging tool for gout.10 Unlike conventional CT scans, DECT has been shown to specifi cally identify uric acid renal stones and colour-differentiate them from other types of renal stones both in vivo and in vitro.11 In 2018-01-19 2014-04-01 2014-03-26 2018-01-27 Background/Purpose: Dual Energy CT Scan (DECT) can detect monosodium urate crystals in joints and periarticular tissues. EULAR gout guidelines (Richette, 2020) recognized DECT’s value in making a clinical diagnosis, when joint aspiration is difficult.

• Data acquired simultaneously with two different beam energies allows dual energy NEW DIAGNOSTIC METHOD FOR GOUT: DUAL ENERGY COMPUTED TOMOGRAPHY INSTEAD OF JOINT ASPIRATION The most reliable method of diagnosing gout is to draw fluid from the joint (arthrocentesis) to verify the presence of monosodium urate crystals (uric acid). Up to now, computed tomography (CT) has played a limited role in the evaluation of gout, since Dual-Energy Computed Tomography (DECT) could essentially change the diagnostic approach to Gout evaluation with TwinBeam Dual Energy TwinBeam Dual Energy Collimation: 64 x 0.6 mm Scan time: 8 s Scan length: 218 mm Rotation time: 0.5 s Tube setting: AuSn 120 kV, 298 eff. mAs CTDIvol: 6.4 mGy DLP: 141 mGy cm Eff. dose: 0.11 mSv Courtesy of Luzerner Kantonsspital, Luzern, Switzerland A research team from the Johns Hopkins Division of Rheumatology including Alan Baer, M.D., Tracie Kurano, M.D., and Janet W. Maynard, M.D. found that a new imaging method called dual-energy computed tomography (DECT) is a promising strategy to identify affected joints in patients with gout.
