Abstract: This paper explored the application value of magnetic resonance (MR) routine and 3D volume-insert air-holding examination (3D-T1-VIBE) sequence scanning in the diagnosis of patients with unilateral knee cartilage motor injury. 198 patients with suspected knee cartilage motor injury were selected as the study subjects. According knee arthroscopic diagnosis as the gold standard, 170 patients were diagnosed with knee cartilage motor injury and 28 patients with non-knee cartilage motor injury. All patients underwent routine MR, 3D-T1-VIBE sequence scanning. Compared with the MR routine and 3D-T1-VIBE sequence scanning single-item diagnosis, the combined test has a higher diagnostic accuracy for the knee joint cartilage motor injury and injury grade (P>0.05). Compared with routine MR and 3D-T1-VIBE sequence scanning single-item diagnosis, the sensitivity (98.82%), specificity (89.28%) and accuracy (97.47%) with combined diagnoses were all higher (P<0.05) of knee cartilage injury. MR routine combined with 3D-T1-VIBE sequence scanning is beneficial to improve the diagnostic accuracy of knee cartilage motor injury.

Key words: unilateral knee cartilage injury, magnetic resonance, 3D volume-insert air-holding examination(3D-T1-VIBE), diagnosis and treatment
