Background:
Laryngeal cancer constitutes a major burden. Accurate staging is important to determine the optimal treatment approach. However, a head-to-head comparison of diagnostic performance between CT and MRI in patients with laryngeal cancer is lacking. Furthermore, the performance of CT and MRI in detecting the invasion of different laryngeal structures is yet to be determined.
Objective:
To compare the diagnostic performance of CT and MRI in patients with laryngeal cancer.
Methods:
We searched PubMed, Scopus, and Web of Science in November 2025 for cohort studies that compared both index tests (CT and MRI) to histopathological examination of laryngeal cancer. We assessed the quality of the included studies using the QUADAS 2 tool. A bivariate meta-analysis was performed using R and RevMan software to compare pooled sensitivity and specificity, with summary receiver operating characteristic (SROC) curves generated for each outcome.
Results:
We included eight studies. The pooled data showed that CT was significantly less sensitive compared to MRI in detecting invasion of the thyroid cartilage with an absolute difference of -0.43 (95% CI -0.59 to -0.26), cricoid cartilage -0.65 (95% CI -1.14 to -0.15), paraglottic space -0.5 (95% CI -0.68 to -0.32), and anterior commissure -0.48 (95% CI -0.1 to -0.86). Specificity was similarly high for both modalities across all structures. For arytenoid cartilage and epiglottis invasion, MRI showed a non-significant trend towards higher sensitivity. Summary receiver operating characteristic (SROC) curves indicated superior overall diagnostic accuracy for MRI. In T-staging, MRI consistently demonstrated a lower rate of understaging compared to CT across five studies.
Conclusions:
MRI had superior diagnostic performance compared to CT in detecting laryngeal cartilage and deep space invasion; it had significantly higher sensitivity, comparable specificity, and lower risk of understaging, thus supporting the use of MRI for accurate pretreatment T-staging. However, given the limited number of studies, the results should be interpreted with caution, and further studies are needed to confirm our findings.
