Psoriatic arthritis.

Area of Science:

• Rheumatology
• Immunology
• Radiology

Background:

• Psoriatic arthritis (PsA) is a chronic inflammatory joint disease associated with psoriasis, distinguished by the absence of rheumatoid factor.
• The etiology of PsA is multifactorial, involving genetic predispositions and environmental triggers, with complex immunological underpinnings driving inflammation.
• PsA commonly affects the axial skeleton asymmetrically and can present with diverse clinical courses, often manifesting as oligoarthritis with inflammatory changes at entheses.

Purpose of the Study:

• To review the role of various imaging modalities in the diagnosis and monitoring of psoriatic arthritis.
• To highlight the evolution of diagnostic tools from classical radiography to advanced imaging techniques.
• To emphasize the impact of early diagnosis on treatment accessibility and prevention of joint damage.

Main Methods:

• Review of classical radiography and its limitations in detecting early psoriatic arthritis.
• Evaluation of advanced imaging modalities including ultrasonography (US), computed tomography (CT), and magnetic resonance (MR) for assessing early inflammatory changes.
• Discussion of the diagnostic utility of these techniques in managing rheumatoid diseases.

Main Results:

• Classical radiography is effective for identifying late-stage bone involvement in PsA.
• Modern imaging techniques like US, CT, and MR enable the assessment and monitoring of early inflammatory changes in PsA.
• These advanced tools facilitate earlier diagnosis and treatment initiation.

Conclusions:

• Advanced imaging modalities are crucial for the early diagnosis and management of psoriatic arthritis.
• Timely detection of inflammatory changes through imaging can significantly delay or prevent destructive joint alterations.
• Improved diagnostic capabilities enhance patient access to modern treatments, optimizing outcomes in PsA.
