Does proton MR spectroscopy accurately detect malignancy in musculoskeletal lesions?
Proton MR spectroscopy, specifically evaluating choline peaks, may serve as a useful adjunct for detecting malignancy in musculoskeletal lesions.
May support choline peak as adjunct for musculoskeletal malignancy detection; leaves open need for prospective validation.
OBJECTIVE: The purposes of this review are to describe the principles and method of MR spectroscopy, summarize current published data on musculoskeletal lesions, and report additional cases that have been analyzed with recently developed quantitative methods. CONCLUSION: Proton MR spectroscopy can be used to identify key tissue metabolites and may serve as a useful adjunct to radiographic evaluation of musculoskeletal lesions. A pooled analysis of 122 musculoskeletal tumors revealed that a discrete choline peak has a sensitivity of 88% and specificity of 68% in the detection of malignancy. Modest improvements in diagnostic accuracy in 22 of 122 cases when absolute choline quantification was used encourage the pursuit of development of choline quantification methods.
