Synopsis

Keywords: Image Reconstruction, Head & Neck/ENT

This study aimed to investigate the value of a dynamic contrast-enhanced (DCE)-MRI with golden-angle radial volumetric‑interpolated breath‑hold examination (radial-VIBE) research application sequence by comparing with conventional VIBE in patients with laryngeal and hypopharyngeal squamous cell carcinoma (SCC) under free breathing conditions. Our results showed that compared with conventional contrast-enhanced VIBE images with single phase, the morphological radial-VIBE images of multitemporal synthesis had significantly higher image quality based on subjective (edge, artifact, and confidence) and objective (signal-to-noise ratio, contrast, and contrast-to-noise ratio) assessments. Therefore, radial-VIBE can be used in DCE‑MRI examination in laryngeal and hypopharyngeal SCC in the free breathing state.
