Markers of joint inflammation related to disease activity in rheumatoid arthritis.
Hurňáková, Jana ; Pavelka, Karel (advisor) ; Horák, Pavel (referee) ; Hrnčíř, Zbyněk (referee)
Background: Rheumatoid arthritis (RA) is a common chronic autoimmune disorder characterised by persistent synovitis, typically manifested as symmetric polyarthritis of small hand joints with various extra-articular manifestations. Accurate disease activity measurement is a key component of RA management that facilitates therapeutic optimalization in order to slow down the disease progression and to prevent an irreversible joint damage. The aim of this work was to study the role of candidate serum inflammatory markers and their associations with the disease activity in patients with RA presented by traditional variables of disease activity as well as by musculoskeletal ultrasonography. Results: The first part of our work pointed out relationship between serum calprotectin and clinical as well as ultrasound activity in RA. We have revealed that serum calprotectin is an independent predictor of ultrasound synovitis. Moreover, we have demonstrated the potential of calprotectin to identify patients with residual activity in spite of achieving clinical remission. In the second part, we have provided a detailed analysis of 20 candidate serum markers and found out a tight associations between IL-6, IL-7, IL-22, IL-34, YKL-40, CXCL-13, MMP-3, resistin and visfatin with clinical and ultrasound activity....
Image segmentation of ultrasound images
Schwarzerová, Jana ; Odstrčilík, Jan (referee) ; Mézl, Martin (advisor)
This bachelor’s thesis deals with basic description of ultrasonography, principles of contrast-enhanced imaging and application of segmentation methods in ultrasound problematics. Some individual methods were implemented in Matlab, version R2015b. Algorithms were tested on synthetic images data, on ultrasound phantom images data and on real ultrasound images. Then the thesis was extended by ultrasound sequences segmentation.
