Quantifying synovitis in rheumatoid arthritis using computer-assisted manual segmentation with 3 Tesla MRI scanning.

Purpose: To investigate the reliability, validity and feasibility of a computer-assisted manual segmentation method for determining the synovial membrane volume as a surrogate measure for synovitis in patients with rheumatoid arthritis (RA).

Materials And Methods: The 3 Tesla (T) MRI scans were acquired in 22 early RA and 16 established RA patients. Synovial membrane volumes in postcontrast T1w axial images at three wrist joint regions were determined by two nonradiologist observers using a computer-assisted manual segmentation method.

Measuring bone erosion and edema in rheumatoid arthritis: a comparison of manual segmentation and RAMRIS methods.

Purpose: To investigate the reliability, feasibility, and validity of a computer-assisted manual segmentation (outlining) technique for measuring magnetic resonance imaging (MRI) bone erosion and edema at the wrist in rheumatoid arthritis (RA).

Materials And Methods: The 3T MRI scans were obtained in 22 RA patients (<2 years). Bone erosion and edema volumes were scored by two readers using outlining and were compared with RAMRIS scores.

Skin-derived tenocyte-like cells for the treatment of patellar tendinopathy.

Background: Recent research of lateral elbow tendinopathy has led to the use of laboratory-amplified tenocyte-like cells.

Hypothesis: Ultrasound-guided injection of autologous skin-derived tendon-like cells are effective compared with other injectable therapies for the treatment of refractory patellar tendinosis.

Study Design: Randomized controlled trial; Level of evidence, 1.

Lateral elbow tendinopathy: correlation of ultrasound findings with pain and functional disability.

Background: Lateral elbow tendinopathy is a common condition often diagnosed by ultrasound. Debate exists regarding which ultrasound findings correlate with disease severity and prognosis.

Hypothesis: Sonographic predictors for tendon healing in patients with lateral elbow tendinopathy can be found by correlating initial ultrasound findings with subsequent changes in pain and functional disability scores after a period of nonoperative management.

Review: imaging of groin pain in the athlete.

Chronic groin pain is a common entity in the sporting population and causes considerable morbidity. The differential diagnosis is wide, and this article presents a review of the common causes with particular reference to anatomy, ultrasound and magnetic resonance imaging (MRI) findings.

Imaging features of foot osteoid osteoma.

Objectives: We performed a retrospective review of the imaging of nine patients with a diagnosis of foot osteoid osteoma (OO).

Materials And Methods: Radiographs, computed tomography (CT) and magnetic resonance imaging (MRI) had been performed in all patients. Radiographic features evaluated were the identification of a nidus and cortical thickening.
