Efficacy of Gadolinium-DTPA enhanced MRI to the tumors in paranasal sinuses

Abstract

We examined whether magnetic resonance imagings (NIRI) after gadolinium-DTPA administration were clinically more useful than nonenhanced MRI in 17 patients with paranasal sinus noeplasm. Seventeen patients underwent MR I both with and without gadolinium-DTPA, and CT. Six of the seventeen cases demonstrated coexisting neoplasm and mucoceles, polyps. Though nonenhanced MRI enabled correct differentiation of 3 of these 6 lesions, gadolinium-enhanced MRI enabled correct differentiation of all 6 lesions.
We concluded that gadolinium-enhanced MRI was useful for differentiating neoplasms and mucoceles or polyps in the paranasal sinuses.
