Is it skin psoriasis or psoriatic arthritis?
Dermatology Times. 2018.
A new report indicates that diagnostic tests for differentiating psoriasis from psoriatic arthritis now includes ultrasound. In patients with psoriatic arthritis, an ultrasound scan can identify inflammation in tendons, affected bones, and other structural abnormalities that are associated with the condition. On the contrary, if the aforementioned abnormalities are not present during the ultrasound, the patient is diagnosed with psoriasis instead of psoriatic arthritis.
