Preclinical evaluation of a miniaturized Deep Brain Stimulation electrode lead.

The effect of miniaturizing the electrode lead for Deep Brain Stimulation (DBS) therapy was investigated in this work. A direct comparison was made between a miniature lead (0.65 mm diameter) and a lead of standard size (1.

Ultrasound-guided hip injections: a comparative study with fluoroscopy-guided injections.

Purpose: The purpose was to assess ultrasound-guided injections through patient satisfaction in a comparative internally controlled study of fluoroscopic versus ultrasound technique and to quantitate the reliability of the ultrasound method. In addition, the reliability of the ultrasound method was quantitated.

Methods: This study consisted of the first 50 consecutive patients to undergo ultrasound-guided intra-articular injection of the hip (by a nurse practitioner) and who had previously undergone fluoroscopy-guided intra-articular injections by our center's fellowship-trained musculoskeletal radiologists.
