Patients with compressive or entrapment neuropathies of the elbow, forearm, wrist, or hand may go straight to sonographic examination. In skilled hands, ultrasound can produce images that reveal pathology as well as MR images can. But while the diagnosis of a tendon rupture is a relatively simple matter with ultrasound, to assess specific neurological injuries, such as nerve entrapment and compression, the technique requires considerable experience, expertise, and patience, said Dr. Javier Beltran of the Maimonides Medical Center in Brooklyn, NY.
Exquisite images of the brain, spine, body, and joints will adorn vendors' booths at the RSNA meeting, attesting to the benefits of clinical 3T. But, unlike the many ultrahigh-field MR scans that vendors have displayed in the past, most of these 3T images will come from systems designed for everyday clinical practice.
