The diagnostic accuracy of ultrasound in the assessment of superficial musculoskeletal soft-tissue tumors is high and can be improved through increased radiologist awareness of less frequently encountered tumors. Ultrasound is accurate for differentiating benign from malignant superficial soft-tissue tumors.

Ultrasound (US) is increasingly being used as the first-line imaging modality for investigating the chest wall for soft tissue and bony lesions. This article describes the technique used for the US examination, the relevant chest-wall anatomy, and the appearances on US scanning of pathologic entities either unique to or common in the region of the chest wall.

DSCA and sagittal AP diameter on standing MRI correlate significantly and better than findings on supine MRI with claudication symptoms. Standing MRI demonstrates dynamic changes of dural sac and provides an additional value to supine MRI in correlating clinical symptoms of lumbar spinal stenosis.

US is highly accurate at diagnosing the presence and type of groin hernia.

Phalangeal microgeodic disease is a rare disease that is frequently (though not invariably) related to cold exposure. In most cases, the clinical and radiographic findings of phalangeal microgeodic disease are sufficient to reach the diagnosis. The magnetic resonance imaging (MRI) findings of phalangeal microgeodic disease have been described in four cases in the English literature with two additional cases presented here. MRI allows a greater appreciation of affected bone areas and adds specificity to radiography with regard to diagnosis. In this sense, MRI is a helpful investigation in those cases of phalangeal microgeodic disease when doubt still exists following clinical and radiographic assessment.

The buttock is a common site of pathology and ultrasound and is often the first-line imaging modality to examine soft tissue lesions of the buttock region. This review describes the ultrasound technique used, the relevant ultrasound anatomy, and the sonographic appearances of common and uncommon pathological conditions found in the buttock region.

Traction MRI of the ankle is safe and technically feasible. This study is the first to date to investigate the effect of ankle traction on the MRI assessment of talar dome osteochondral lesions. Traction improves cartilage surface visibility of talar dome osteochondral lesions.
