Does Immobilization Post Injection Reduce Contrast Extravasation in MR Arthrography of the Shoulder?

Background: Contrast leakage after arthrography is common. We sought to investigate if immobilization could prevent it.

Purpose: The purpose of this study was to determine the effects on contrast extravasation and image quality produced by strict immobilization of the shoulder between arthrography puncture and subsequent MR imaging.

Sonographic evaluation of the plantar fascia in asymptomatic subjects.

Purpose: To evaluate the appearance of the plantar fascia in asymptomatic subjects.

Materials And Methods: Thirty-one asymptomatic subjects were examined by 2 musculoskeletal radiologists. The plantar fascia was evaluated for thickness, echogenicity, vascularity on power Doppler, rupture, fluid adjacent to the fascia, andcalcifications.

A bare area of the glenoid misdiagnosed as a cartilage ulceration.

We report on a 17-year-old girl who developed shoulder pain after a fall on an outstretched arm. CT arthrography and MR imaging demonstrated a cartilage defect centrally located in the glenoid. This was accompanied by an eroded appearance of the underlying bone.

Pigmented villonodular synovitis of the midfoot.

A 60-year-old man presented with a longstanding slowly growing swelling at the dorsal aspect of the left midfoot. The lesion was imaged with CT, ultrasound, and MR. On CT bony erosions were evident.

An unusual case of cat-scratch disease of the knee: case report and differential diagnosis.

We present a case of a 16-year-old boy with a painful swelling in the popliteal fossa, slight fever, articular and muscle pain of 3 weeks duration. Plain radiography and MR examination were performed in order to characterize the lesion. Additionally to the poorly defined mass, 2 satellite nodules were shown.
