(A) Ethanol-fixated sample showing large tophaceous The standard way to check for gout is by drawing fluid or tissue from an affected joint and looking for uric acid crystals, a test known as a needle aspiration. That usually works, but not always: In a new Mayo Clinic study, X-rays known as dual-energy CT scans found gout in one-third of patients whose aspirates tested negative for the disease. TwinBeam Dual Energy (TBDE) allows simultaneous acquisition of high and low kV datasets in a single spectral CT scan by splitting the X-ray beam with two filters before it reaches the patient, enabling high-contrast dynamic applications 2011-11-29 · Comment. Dual-energy CT could emerge as a useful adjunctive diagnostic tool for patients with suspected but unproven crystal-induced arthritis. However, for the procedure to be cost-effective, clinicians will need to employ it selectively for cases with genuine diagnostic uncertainty. To evaluate the potential utility of a dual energy CT (DECT) scan in assessing urate deposits among patients with tophaceous gout, and obtain computerised quantification of tophus volume in Encouraged by the success of the Dual-Source CT system Somatom Definition with two X-ray tubes that simultaneously generate different energies, Siemens Healthcare has already developed six specific dual energy applications.

DUAL-ENERGY CT AS A POTENTIAL NEW DIAGNOSTIC TOOL IN THE MANAGEMENT OF GOUT IN THE ACUTE SETTING Objective: Gout is the most common crystal deposition arthropathy currently diagnosed clinically and with arthrocentesis. Dual-energy CT is a promising new imaging technique offering potential new applications in a number of clinical areas. Dual-energy CT can distinguish between urate mineralization and calcification, which may be useful for cases where the clinical and biochemical presentation is atypical 11. Allowing for not only visualization and characterization, but also quantification of monosodium urate crystal deposits, it can be used for treatment monitoring as well 14 . Dual Source CT for Gout.

However, when evaluating gout patients, DECT frequently colour-codes material not truly representing MSU crystals and this might lead to misinterpretations. The aim of our study was to compare dual-energy CT (DECT) with US for the diagnosis of gouty arthritis and to correlate the imaging findings with results from synovial fluid aspiration whenever possible. 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. Se hela listan på hopkinsrheumatology.org None of the methods described above are sufficiently sensitive or specific for the diagnosis of gout, which relies on the identification of MSU crystals.

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. Why was this study done? Dual-energy computed tomography (CT) is a relatively new approach to gout diagnosis that provides images in which gout crystals appear as specifically colored densities in affected joints or A definite diagnosis of gout requires demonstration of monosodium urate crystals in synovial fluid or in tophi, which in clinical practice today seldom is done. Dual energy CT (DECT) has repeatedly been shown to be able to detect monosodium urate crystals in tissues, hence being an alternative method to synovial fluid microscopy.
