1H-MR Spectroscopy of Bone and Soft Tissue Tumors with in Vivo / 实用放射学杂志

ABSTRACT

Objective To determine if in vivo detection of choline by1H-magnetic resonance spectroscopy(1H-MRS) could differentiate between benign and malignant bone and soft tissue tumors.Methods MR spectroscopy was performed in 28 cases, including 5 healthy subjects and 23 cases of extremital tumors. Examination was performed by using a point-resolved spectroscopic sequence with echo times of 35,144 and 288 ms.Results 1H-MRS spectrum was different among normal tissue, benign and malignant tumor.Conclusion Choline can be reliable detected in malignant tumor of bone and soft tissue by using1H-MRS.1H-MRS can help differentiate malignant tumor from benign tumor.
