摘要
目的比较1.5T磁共振成像(MRI)常规序列与T1 VIBE DIXON增强序列在诊断卵巢囊腺瘤内部结构的价值。方法采用回顾性研究,收集本院49例经手术病理证实为卵巢囊腺类肿瘤的临床及影像资料,应用Siemens Avanto Dot1.5TMR机对上述患者行常规及T1 VIBE DIXON增强序列扫描,比较两者的病灶内部结构显示率,对数据做相应统计学比较,并对所获图像进行分析。结果 49例患者中,常规MRI序列、T1 VIBE DIXON增强序列检出囊壁及分隔不均匀增厚分别为31个,41个;检出结节(乳头)状突起分别为28个,40个;检出出血坏死灶分别为7个,9个;出盆腔积液23个,24个。经统计学分析,T1 VIBE DIXON增强序列对卵巢囊腺类肿瘤囊壁及分隔不均匀增厚,结节(乳头)状突起的检出率明显升高,且与常规MRI序列比较有统计学意义(P<0.05);在对出血坏死灶及盆腔积液的检出率与常规MRI序列比较差异无统计学意义(P>0.05)。结论相比1.5T MRI常规序列,T1 VIBE DIXON增强序列在显示卵巢囊性类肿瘤囊壁及分隔不均匀增厚,结节(乳头)状突起方面具有更高的诊断价值,对于病变的定性诊断颇有帮助,但其在显示盆腔整体解剖结构、肿瘤囊性灶、出血坏死灶及盆腔积液方面并不明显优于常规序列,因此临床中应结合二者进行综合判断以提高卵巢囊腺类肿瘤的定性诊断。
【Objective】To compare the value of 1.5 T magnetic resonance imaging sequence with T 1 VIBE DIXON enhanced sequence in the diagnosis of internal structure of ovarian cystadenoma.【Methods】The clinical and imaging data of 49 cases of ovarian cystadenoma proved by surgery and pathology were retrospectively studied.Siemens Avanto Dot 1.5 T MRI was used to scan the routine and T 1 VIBE DIXON sequences of these patients,the display rate of the internal structure of the lesions was compared,the data were statistically compared,and the images obtained were analyzed.【Results】In 49 patients,31 and 41 cystic wall and inhomogeneous thickening,28 and 40 tubercle(papilla)processes,7 and 9 hemorrhagic necrosis foci,23 and 24 pelvic effusion foci were detected by conventional MRI and T 1 VIBE DIXON contrast-enhanced MRI.Statistical analysis showed that the detection rate of T 1 VIBE DIXON enhanced sequence was significantly higher than that of conventional MRI sequence(P<0.05).There was no significant difference in the detection rate of hemorrhagic necrotic focus and pelvic effusion when we compared T 1 VIBE DIXON contrast-enhanced sequence with conventional MRI sequence(P>0.05).【Conclusion】Compared with the conventional 1.5 T MRI sequence,the T 1 VIBE DIXON enhanced sequence has higher diagnostic value in displaying the cystic wall,inhomogeneous thickening and tuberous(papillary)process of ovarian cystic tumors,and is helpful for the qualitative diagnosis of the lesions,however,it is not superior to the conventional sequence in showing the overall anatomy of the pelvic cavity,tumor cystic foci,hemorrhagic necrotic foci and pelvic effusion,therefore,we should combine the two methods to improve the qualitative diagnosis of ovarian cystadenoma.
