【摘要】：目的探讨灰阶超声联合弹性成像预测乳头状甲状腺微小癌(PTMC)外浸润的价值。方法回顾性分析82例共96个PTMC病灶的超声特征及相关的病理结果,超声特征包括病灶的数量、位置、最大径、内部回声、边界、弹性评分及应变率等。分析PTMC超声特征与甲状腺外浸润、中央淋巴结转移和侧方淋巴结转移的相关性。结果超声和病理测得的96个PTMC病灶最大径分别为(7.32±2.16)mm、(7.46±2.28)mm,二者差异无统计学意义(t=0.79,P0.05)。病理T分期T1、T2、T3分别为4、16、76个,超声T分期T1、T2、T3分别为5、13、78个,二者差异无统计学差异(χ2=5.53,P0.05)。多因素分析显示,超声T分期、甲状腺外浸润及弹性评分与甲状腺外浸润相关;中央淋巴结转移与超声诊断双侧性、侧方淋巴结转移相关;侧方淋巴结转移与超声诊断的侧方淋巴结转移相关。结论灰阶超声联合弹性成像有助于预测PTMC甲状腺外浸润。
[Abstract]:Objective to evaluate the value of gray scale ultrasonography combined with elastic imaging in predicting external invasion of papillary thyroid microcarcinoma (PTMC). Methods Eighty-two patients with 96 PTMC lesions were analyzed retrospectively. The ultrasonographic features included the number, location, maximum diameter, internal echo, boundary, elastic score and strain rate of the lesions. To analyze the correlation between PTMC ultrasound features and extrathyroid invasion, central lymph node metastasis and lateral lymph node metastasis. Results the maximum diameter of 96 PTMC lesions measured by ultrasound and pathology was 7.32 卤2.16mm and 7.46 卤2.28mm, respectively. There was no significant difference between them. The T _ 3 of T _ 1T _ 1 and T _ 2T _ 3 of T _ (1) and T _ (2) T _ (2) T _ (2) T _ (2) T _ (1) and T _ (2) T _ (2) T _ (2) T _ (2) T _ (2) T _ (2) T _ (3) and T _ (1) T _ Multivariate analysis showed that ultrasound T stage, extrathyroid invasion and elastic score were correlated with extrathyroid invasion, central lymph node metastasis was correlated with ultrasonography diagnosis of bilateral and lateral lymph node metastasis. Lateral lymph node metastasis was associated with ultrasonic diagnosis of lateral lymph node metastasis. Conclusion Gray scale ultrasonography combined with elastic imaging is helpful to predict the extrathyroid invasion of PTMC.
