Computed tomography appearance of normal nonossified thyroid cartilage: implication for tumor invasion diagnosis.

Objective: The objective of this study was to determine the density and homogeneity of the nonossified thyroid cartilage (NOTC) on contrast-enhanced computed tomography (CT) providing preliminary information for future evaluation of cartilage invasion using dual-energy CT.

Methods: One hundred normal-larynx CT scans were evaluated for the density and homogeneity of NOTC.

Results: The density of the NOTC was homogeneous in all cases.
