【摘要】：目的:探讨不同类型钙化对甲状腺良恶性结节的诊断价值。方法:收集284例患者306个结节,所有结节内超声均发现钙化,根据钙化形状不同将其分型,以病理结果为金标准,分为良性组和恶性组,进行统计。结果:良恶性结节均可发钙化,在男女发病率上没有差异(P=0.242),在结节的大小上也没有差异(P=0.245),在发病年龄上有显著差异(P=0.000),不同钙化类型上,Ⅰ和Ⅱ、Ⅳ间差异有统计学意义,Ⅰa和Ⅰb、Ⅰ和Ⅲ、Ⅱ和、Ⅲ、Ⅱ和Ⅳ、Ⅲ和Ⅳ间差异无统计学意义。有钙化结节良恶性在边界、形态、纵横比上差异有统计学意义,在回声特质上没有差异。结论:当有钙化的结节出现边界不清楚、形态不规则、纵横比≥1、低回声时考虑恶性可能,微钙化是诊断恶性的一个较好的指标,微钙化数越多,恶性可能越大;弧形钙化良恶性结节均可见,粗钙化及环状钙化多见于良性结节。
[Abstract]:Objective: To investigate the diagnostic value of different types of calcification in benign and malignant thyroid nodules. Methods: 284 patients with 306 nodules, nodules were found in all ultrasonic calcification, according to the different shape of calcification type, with pathological results as the gold standard, divided into benign and malignant groups were statistically. Results: benign and malignant can nodules of calcification, in male and female incidence was not different (P=0.242), and there was no difference in nodule size (P=0.245), there was significant difference in age of onset (P=0.000), different types of calcification, I and II IV, there was significant difference between two groups, I a and I B, and I III, II, III, II and IV, there was no significant difference between 3 and 4. Calcified nodules in the boundary, shape, aspect ratio had a significant difference, there is no difference in the echo characteristics. Conclusion: when calcified nodules appeared in the boundary is not clear, irregular shape, aspect When the ratio is more than 1, low echo consider the possibility of malignancy, microcalcification is a better indicator of the diagnosis of malignant microcalcifications, the number, the more likely malignant; malignant and benign nodules were visible curved calcification, coarse calcification and annular calcification usually occurred in benign nodules.

【正文快照】： 甲状腺结节是甲状腺常见的病变,患病率约为样。如果结节内同时伴有微钙化和粗钙化时,将其归17%~27%[1],其中约占5%~15%为甲状腺恶性肿为记录为Ⅰ型。以正常甲状腺组织作为对比,将结节瘤[2]。随着超声图像分辨率的提高,甲状腺结节的检回声分为低回声(明显低于周围甲状腺组织回
