Nerves are composed by hypoechoic fascicules within a hyperechoic environment. Less subject to anisotropy and soft to the pressure of the probe, nerves lie between muscles, often with vessels, or within channels. Recent advances in sonographic technology allow accurate imaging of peripheral nerves of the upper and lower limbs, but adequate anatomical and clinical knowledge, as well as rigorous technique are mandatory. The purpose of this general review is to present, as clearly as possible, in two parts, the sonographic features of normal and pathological nerves of upper and lower limbs. This first part will discuss nerves of the upper limb.

It completes the information provided by panoramic X-rays and scanner. The technique is based on proton excitation within an intense magnetic field and does not release any ionizing radiation, as opposed to conventional images (panoramic and CT scanner). This technique is harmless, provided that known and continuously updated contraindications be complied with. Its major advantages include imaging within different spatial planes without moving the patient and its excellent tissular discrimination capacities. The latter quality accounts for spontaneous visibility of the TMA disc. Currently, it is the golden standard in exploring painful TMAs (internal derangements).

Normal aging is observed on CT and especially on MRI: these changes should be recognized and differentiated from pathological brain anomalies. The authors briefly describe changes demonstrated by CT and MRI in the most commonly encountered dementia: still emphasis is put on the fact that these anomalies are poorly specific and never pathognomonic. On the contrary, it must be prompted to perform CT and MRI in demented patients in order to rule out diseases curable by surgery such as normal pressure hydrocephaly, subdural hematoma, meningioma and so on especially well demonstrated by CT and MRI.

On CT, these lesions were characterized by very negative density values. Sonography was useful to differentiate a lipoma from an old hematoma that share the same signal on MRI. Eighteen cases of biopsy proven liposarcomas were evaluated with at least two techniques. Tumor heterogeneity was the most important clue to malignancy. With CT, contrast injection was necessary because two cases out of eight appeared homogeneous on native examinations. Lobular pattern and large size are constant signs associated with liposarcoma. The correlation of imaging and histology classification was only successful with differentiated tumors. Angiography unspecifically reveals the malignancy of liposarcoma. MRI is better than CT to evaluate tumor expansion and to differentiate the mass from the surrounding tissue.

It is important that osseous structures as well as soft tissue can be shown. Transcranial images, conventional tomography, panoramic radiography and computed tomography (CT) are more suitable for viewing the osseous structures. The best techniques to evaluate the soft tissues are arthrography and especially magnetic resonance imaging (MR). The panoramic radiography is the technique of choice in the general practice and provides adequate screening images of the temporomandibular joints, mandible, maxilla, teeth and surrounding tissues. When the joint is suspected of developmental anomalies, neoplastic conditions or a condylar trauma, CT-images are necessary to depict the bony abnormalities. CT has a poor reliability in imaging the disk. For this reason, disk displacements of the temporomandibular joint are best shown with MR, although the clinician should be very restrictive in using MR-images. They are very expensive and are only useful to confirm an uncertain diagnosis, or if disc surgery is the treatment of choice. The anamnesis and the clinical investigation are still the most important elements in diagnosing craniomandibular dysfunction.
