Plaque Psoriasis
Conditions
Brief summary
Psoriasis (PsO) is a common chronic relapsing inflammatory disease, induced by a combination of genetic and environmental effects, which seriously affects the quality of life of patients.Psoriasis Area and Severity Index（PASI score ） ，as the most common method used by clinicians to assess the severity of psoriasis and the effectiveness of treatment, has the disadvantage of being subjective and superficial.We are therefore committed to establishing an objective, real-time, repeatable, non-invasive, microscopic assessment using high-frequency ultrasound. This study will use high-frequency ultrasound to detect the patient's lesion site and the 2cm site next to the lesion once, and the study will continue to recruit for 6 months.
Detailed description
High-frequency ultrasound (HFUS) with a center frequency of more than 10 MHz, and a resolution of 16-158 μm. The detailed detection items are epidermal thickness (unit mm), dermal thickness (unit mm), hypoechoic cord thickness between epidermis and dermis (unit mm), epidermal echo intensity, dermal echo intensity, clarity of the boundary between dermis and subcutaneous tissue detected by Grayscale ultrasound; blood flow signal (pcs) detected by Color Doppler imaging and Power doppler imaging. The 8 tests will be detected the skin lesions and 2cm beside skin lesions area.Based on the correlation between the 8 indexes and local PASI scores, we will establish a model for the evaluation of psoriasis by multimodal high-frequency ultrasound.This study will use high-frequency ultrasound to detect the patient's lesion site and the 2cm site next to the lesion once, and the study will continue to recruit for 6 months
