Percutaneous placement of marking coils before stereotactic radiation therapy of malignant lung lesions.

Purpose: To evaluate a technique for implantation of radiopaque markers in lung nodules as an aid in extracranial stereotactic radiation therapy.

Materials And Methods: An implantation technique was developed for marking intrapulmonary lung lesions by introducing a vascular coil through a coaxial needle in or near the target tumor. The markers were placed percutaneously through 15- or 20-gauge coaxial needles in 41 lesions (25 patients) under computed tomographic fluoroscopic guidance.

Peroneal nerve injury in three patients with knee trauma: MR imaging and correlation with anatomic findings in volunteers and anatomic specimens.

The aim of this article is to report on three patients with injuries of the peroneal nerve along the posterolateral aspect of the knee. Injuries in this area are less common than the injuries occurring at the level of the fibular head. In this article we report on three patients with posterolateral knee trauma who had peroneal nerve dysfunction.
