[CT scan, MR imaging and anatomopathologic correlation in the glottic carcinoma T1-T2]

Area of Science:

• Otolaryngology
• Radiology
• Oncology

Background:

• Accurate diagnosis of glottis carcinoma is essential for effective treatment.
• Computed tomography (CT) is the current standard for imaging, but magnetic resonance (MR) imaging may offer superior sensitivity for detecting neoplastic invasion.

Observation:

• A prospective study compared CT and MR imaging in seven patients with early-stage (TI-T2) glottis carcinoma.
• Imaging findings were correlated with postsurgical pathological examinations.

Findings:

• Both CT and MR imaging demonstrated high specificity (90%) but moderate sensitivity (74%) for neoplastic invasion.
• Difficult areas for analysis included the anterior commissure, ventricles, subglottis, thyroid, and arytenoid cartilages.

Implications:

• CT imaging remains the gold standard for initial diagnosis of glottis carcinoma.
• MR imaging serves as a valuable complementary tool for refining diagnostic data, especially for assessing invasion.
• Improved diagnostic accuracy can lead to more tailored treatment, potentially increasing cure rates and preserving laryngeal function.
