    摘要: Background: Minimally invasive interventional biopsy procedures have the advantages of accurate localization, small incisions, and rapidrecovery. The purpose of this study was to clinically test and evaluate the efficacy of the magnetic resonance imaging (MRI)-guidance techniquesfor obtaining musculoskeletal biopsies using the appropriate imaging modalities and instruments.Methods: We used MRI-compatible biopsy needles from the Invivo Bone Biopsy Set (Daum, Germany), and a 1.5-T closed-magnet MRI scannerwas used to perform the MRI-guided biopsy. The pulse sequences included fast spin echo T1- and T2-weighted imaging and gradient echoimaging. The inclusion criteria included the presence of bone or soft tissue masses, infectious disease, and other nonspecific lesions that requiredtissue confirmation. Lesions that could not be visualized by computed tomography (CT) or other imaging modalities were preferred.Results: From January 2005 through December 2009, 23 patients (12 males and 11 females, aged 11 e 82 years) underwent musculoskeletalMRI-guided biopsy. The biopsy locations were as follow: spine (n ¼ 12), tibia (n ¼ 3), pelvis (n ¼ 1), femur (n ¼ 2), scapula (n ¼ 1), humerus(n ¼ 1), ulna (n ¼ 1), scapula (n ¼ 1), and soft tissue mass of the shoulder (n ¼ 1). The final diagnoses included bone metastasis (n ¼ 7), spinalosteomyelitis and discitis (n ¼ 5), osteonecrosis after chemotherapy (n ¼ 4), bone marrow change or benign lesion without malignancy (n ¼ 3),insufficiency fracture (n ¼ 1), long bone osteomyelitis (n ¼ 1), soft tissue metastasis (n ¼ 1), and perineural ganglion cyst (n ¼ 1). In 10 of the23 cases, the lesions were barely visualized or invisible on CT guidance. Pathologic analysis and laboratory culturing revealed that the lesionswere successfully accessed by MRI-guided biopsy in 100% (23/23) of cases. No obvious complications developed during or after the procedures.Conclusion: Biopsy under MRI guidance is especially valuable for the localization of bone marrow lesions, viable tumors (after chemotherapy orradiation), and lesions that cannot be visualized using CT. It is both accurate and safe, is a good alternative biopsy method, and may be a goodadjunctive technique for the localization of bone lesions for radiofrequency ablation or other interventional procedures.
