Comparison of CT and NLS-graphy results in
diagnostics of salivary glands diseases demonstrated that NLS-graphy with
spectral-entropy analysis must be chosen as treatment method in case of tumors
because of its high sensitivity, whereas CT must be chosen when dealing with
deep-seated tumors for their full three-dimensional detection and determination
of facial nerve and tumor ratio, which determines further treatment. We believe
that in most cases NLS-graphy is sufficient for preliminary neoplasms
diagnosing, CT is used in case of deep lobe affection or suspected malignant
process. Intravenous enhancement during CT is useful in non-glandular formations
(especially those located in peripharyngeal space) for detection and
localization of masses in relation to carotid artery or jugular vein.
In case
of formation more than 3 cm in diameter (regardless of its nature and
localization) it is always necessary to use computer tomography to obtain
accurate data on tumor spread into the surrounding tissues. 3D NLS-graphy
demonstrated 100% sensitivity, 96.3% specificity, 97.7% accuracy, CT showed
97.6, 96.4 and 97.6%, respectively in detection of pleomorphic adenomas of large
salivary glands.
