High-resolution magnetic resonance imaging in study of the skin: normal patterns.

Purpose: To validate quantitative and qualitative criteria of normal healthy skin using high-resolution MR imaging.

Materials And Methods: FIESTA and spin echo sequences of the skin of the heel, back and calf were obtained in 31 healthy volunteers. A dedicated 3-in.

[Shoulder pain: imaging examinations].

Non-traumatic shoulder pain is a diagnostic challenge for clinicians. Usually, the clinical examination is supplemented by nowadays well-defined imaging studies. Radiography is the first examination to be requested on a systematic basis.

Extrasynovial ultrasound abnormalities in the psoriatic finger. Prospective comparative power-doppler study versus rheumatoid arthritis.

We prospectively compared power Doppler ultrasound findings in 25 fingers with rheumatoid arthritis (RA) and 25 fingers with psoriatic arthritis (PsA). Erosive synovitis and tenosynovitis were seen in both groups. Extrasynovial changes were found in 21/24 (84%) fingers with PsA versus none of the fingers with RA.

Acitretin-induced enthesitis in a patient with psoriatic arthritis.

A patient with psoriatic arthritis and cutaneous psoriasis took acitretin for 10 years to treat his skin lesions. Radiographs disclosed exuberant ossifications in several entheses. Their features were not typical for psoriatic arthritis but were consistent with acitretin-induced hyperostosis.

Percutaneous catheterization of the long bones: experimental study.

The objective of this study was to develop a technique which would permit access to the entire contents of long bones using a minimally invasive approach. Vascular catheterization techniques were used to allow access to the entire marrow cavity through a minimal percutaneous approach. A new device was also developed to reach the epiphysis of the long bone.
