The metal artifacts caused by metal copings in porcelain fused to metal (PFM) always impair MRI quality. This study aimed to compare MRI quality between common FSE T2WI with PROPELLER FSE T2WI for patients with various metal copings. Fifty-nine subjects with the most commonly used PFM were recruited and imaged at 1.5T MRI system. By comparing the image quality and artifact areas, we found PROPELLER technique was less sensitive to metal artifacts than common FSE. It can be proposed the PROPELLER FSE T2WI to be used as clinical MRI examination of oral cavity and maxillofacial part for patients with PFM.
