双能CT虚拟去钙及mDixon-Quant技术在多发性骨髓瘤中的研究进展

Progress of Dual-Energy CT Virtual Noncalcium and mDixon-Quant Techniques in Multiple Myeloma

多发性骨髓瘤是一种多见于老年人的血液系统恶性肿瘤,主要特征是骨髓浆细胞异常增生取代正常的骨髓,使椎体骨髓水脂比例发生改变,导致骨质破坏和骨髓浸润。目前双能CT虚拟去钙技术和MRI多回波Dixon脂肪定量技术能够检测骨髓的变化并对骨病变进行定性及定量分析,可协助诊断多发性骨髓瘤、提示治疗反应和判断预后。本文拟综述上述两种定量技术在多发性骨髓瘤中的应用价值,为本病的诊断及治疗提供影像学参考。

Multiple myeloma is a kind of hematological malignancy commonly seen in the elderly.Its main feature is that abnormal proliferation of bone marrow plasma cells replace normal bone marrow,which changes the water fat ratio of vertebral bone marrow,leading to bone destruction and bone marrow infiltration.At present,dual energy CT virtual non calcium and modified Dixon Quant can detect the changes of bone marrow and conduct qualitative and quantitative analysis of bone lesions,which can assist in the diagnosis of multiple myeloma,prompt treatment response and judge the prognosis of patients.This paper reviews the application progress of the above two quantitative techniques in multiple myeloma,in order to provide imaging reference for the diagnosis and treatment of multiple myeloma.
