摘要目的评估MRI对称性横断面T2加权-快速自旋回波(TSE)(pa T2)序列成像和抑脂质子密度(pa PDFS)序列成像对骶髂关节(SIJ)强直脊柱炎(Sp A)病人的诊断价值。材料与方法对106例临床诊断有Sp A症状的病人行SIJ pa PD-FS成像(41例病人)和pa T2成像(105例病人)。通过pa PD-FS和金标准——增强后序列影像相比较,评估出急性征象[骨髓水肿(BME)、附
Abstract Objective To evaluate the effect of T2 weighted-fast spin echo (TS T2) imaging and lipid-lipid proton density (paP PDFS) imaging on sacroiliac joint (SIJ) ankylosing spondylitis (Sp A) The patient’s diagnostic value. Materials and Methods SIJ pa PD-FS imaging (41 patients) and pa T2 imaging (105 patients) were performed on 106 patients with clinically diagnosed Sp A symptoms. Acute signs of [bone marrow edema (BME) were evaluated by pa PD-FS in comparison with gold standard-enhanced sequence images
