Magnetic resonance imaging of the anatomy of the parotid gland

Magnetic Resonance Imaging of the anatomy of the parotid gland. In this work are been examined the parotid gland of 30 patients (20 male, 10 female) o/ this eighteen voluntary and 12 arrived at our observation /or SNC pathology. It is been used as a superconductive magnet Philips 'gyroscan' at 1,5 T with head coi! by 35 cm and supeificial and circular coil by 20 cm. The multiplanar scan was executed with TR = 700-2000 ms and TE = 30-90 ms. The RM is been shown very accurate in the anatomic study o/ the parotid gland that appear o/ signal modest hyperintensity in the Tl -weighted images and hyperintense in the T2-weighted images /or her high contents of water that it is due to the gland part and to the stroma! fatty tissue. In 90% of the case studied we show the intraparotid way of the facial nerve in every sequence that we used, like a structure hypointense with respect to the neighboring parenchima.
