Zusammenfassung
Purpose: MRI demonstrated to be a sensitive method for the detection of chondral pathology. Various sequences have been recommended to depict hyaline cartilage. Since the cartilage layer commonly is very thin, high-resolution techniques are desirable. MRI at 3.0T offers a higher SNR than at 1.5T. The aim of this study was to evaluate the diagnostic accuracy of various MR sequences at 1.5 and 3.0T. Method and materials: We used 6 fresh frozen cadaver limbs with twelve artificially generated chondral defects of varying depth, width and location. All joints were examined with 3 fat-suppressed imaging sequences: (1)…
