Objective Bone tumors and tumor-like lesions require that comprehensive imaging contains soft tissues and bone structures. There are so many kinds of examinations that the patients with bone tumors and tumor-like lesions should be performed. The objective of this study was to demonstrate the clinical applicability of zero echo time (ZTE) magnetic resonance (MR) imaging in osseous bone tumor imaging and evaluate the image quality between computed tomography (CT) and ZTE imaging of bone tumors and tumor-like lesions. Materials and methods Thirty-six patients included 18 male patients (mean age: 35 ± 20 years) and 18 female patients (mean age: 42 ± 20 years) were recruited from a clinical cohort of patients undergoing MR and CT. We presented a novel scanning technique for MR scanners (750 W MR, GE Medical Systems) that could obtain ZTE images. ZTE images were acquired after standard-of-care MR imaging. Quality comparison of osseous findings was performed between ZTE and CT imaging using a five-point grading scale. The differences of image quality between ZTE and CT imaging were investigated using Mann–Whitney test. A significance level of P
