Abstract
Different pathological conditions affect the salivary glands. The commonest pathologies include: sialolithiasis, obstructive sialadenitis, infective sialadenitis, granulomatous disorders, Sjögren syndrome, sialosis, human immunodeficiency virus (HIV) sialopathy, and different salivary gland tumors. Many imaging modalities are available to assess the salivary glands.
The gold standard examination for evaluation of the ductal system of the major salivary glands is Conventional sialography, and can delineates the ductal system down to fourth order branches.
Magnetic resonance (MR) sialography is a non-invasive tool for imaging of the ductal system of major salivary glands. This technique is based on principles of MR hydrography, in which very heavily T2-weighted (T2W) pulse sequences are used to image static fluid. MR sialography is fast and is as good as the conventional sialography in demonstrating the entire ductal system.
The present study was designed to evaluate the role of MR sialography in the diagnosis of salivary gland diseases compared to conventional sialography.
Twenty seven patients with symptoms related to salivary glands with age range (22-69 years) were included in the study. Nearly all patients underwent MR sialography and conventional sialography examinations. These examinations were held at the Misr Radiology Center.
