摘要
宝石能谱CT是由传统CT转型而成的新型CT,球管可进行高、低能量X线瞬时切换,弥补了常规CT的缺点,有助于进一步区分不同组织成分。近年来能谱CT成像在骨质疏松程度的诊断,关节置换术后检查,痛风结石诊断与鉴别,骨髓瘤与骨转移瘤、骨岛的鉴别,骨损伤程度的诊断以及肌腱病变的诊断等方面的应用研究均取得了一定进展。虽然能谱CT成像对于骨密度的诊断尚无定论,有待进一步探究,但是从多方面综合评价,能谱CT成像对骨骼系统疾病的评估有巨大价值。本文将从以上几个方面对能谱CT在骨骼系统疾病中的应用进展进行综述。
Gemstone spectral CT is a new type of CT transformed from traditional CT. The tube can take advantage of the highand low-energy X-ray instantaneous switching, which not only makes up for the shortcomings of conventional CT, but also helps to further distinguish the components of different tissues. In recent years, energy spectrum CT has been used for the diagnosis of skeletal system lesions, such as diagnosis of osteoporosis, examination after arthroplasty, differential diagnosis of gout stone, differential diagnosis among myeloma, bone metastasis and bone island, diagnosis of bone injury, and diagnosis of tendon lesions. Some progresses have been made in the diagnosis of skeletal system lesions with energy spectrum CT, and the application of gemstone spectral CT in skeletal system is worthy to be further investigated. Although the diagnosis of bone mineral density with energy spectrum CT is still inconclusive, the comprehensive evaluation showed that energy spectrum CT has great values in the evaluation of skeletal system diseases. Herein the application of energy spectrum CT in skeletal diseases is reviewed from several aspects.
