Urate crystals can usually be seen by examination of joint fluid or gout stone contents, ultrasonography, and dual-energy CT.
1. Joint fluid or gout stone content examination: joint fluid or gout stone content can be seen under polarized light microscope double refractive needle-shaped urate crystals.
2. Ultrasonography: joint ultrasonography can see double track sign or uneven hypoechoic and hyperechoic mixed mass shadow.
3. Dual-energy CT: Dual-energy CT can specifically identify urate crystals.
Urate crystals are usually caused by high levels of uric acid in a saturated solution, resulting in the formation of urate crystals and their deposition in the joints and surrounding tissues.
It is recommended that patients improve the above and other related tests under the guidance of a specialist.
In addition, it is recommended that patients can drink more water every day to promote the excretion of uric acid, in order to reduce the deposition of crystals in the body. At the same time should quit smoking and drinking, avoid the intake of high purine food, such as seafood, animal offal, etc., so as not to aggravate the condition.
