Ultrasound-Guided Synovial Biopsies of Wrists, Metacarpophalangeal, Metatarsophalangeal, Interphalangeal Joints, and Tendon Sheaths.

Ultrasound-guided synovial biopsy (UGSB) is a minimally-invasive procedure which allows quality synovial tissue retrieval. In this article, we will discuss overarching principles of the procedure performed in wrists, metacarpophalangeal (MCP), metatarsophalangeal (MTP), interphalangeal joints (IP), and tendon sheaths, including basic sonoanatomy, entry site and biopsy technique, as well as special considerations for each structure whenever relevant.

Ultrasound-guided synovial biopsy: a systematic review according to the OMERACT filter and recommendations for minimal reporting standards in clinical studies.

Objectives: To describe existing techniques of US-guided synovial biopsy (USG-SB) and critically appraise the literature on this technology through the OMERACT filter.

Methods: USG-SB techniques are described and compared. A systematic literature search of PubMed and Embase was performed for original research reports including US and SB.

Clues to the pathogenesis of psoriasis and psoriatic arthritis from imaging: a literature review.

This article summarizes a presentation on imaging of skin and joints in patients with psoriasis and psoriatic arthritis (PsA) from the 2007 Annual Meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA). Plain radiography provides valuable insights into the pathogenesis of PsA but is limited because only calcified tissue can be imaged. Newer techniques such as magnetic resonance imaging (MRI) and ultrasound (US) provide additional clues to the pathogenesis of this peripheral, axial, and dermatologic disease.
