【摘要】 目的 探討彈性成像在甲狀腺微小癌診斷中的應用價值。 方法 回顧性分析從2007年12月-2008年4月間經病理證實的10例甲狀腺微小癌患者共11個病灶的超聲表現。 結果 彩色多普勒超聲診斷甲狀腺微小癌8例8個病灶,利用彈性成像技術診斷10例10灶。傳統彩色多普勒超聲對甲狀腺微小癌的診斷率為72.7%;利用彈性成像技術對甲狀腺微小癌的診斷率為90.9%。 結論 彈性成像技術對于甲狀腺微小癌是對彩色多普勒超聲檢查的有益的補充,能夠顯著提高超聲對甲狀腺微小癌診斷的準確性。【Abstract】 Objective To evaluate the application of US-elastography in diagnosis of thyroid microcacinoma. Methods The images of color ultrasound and ultrasound elastography from 11 lesions of 10 patients with thyroid micro-carcinoma diagnosed via histopathology between December 2007 and April 2008 were retrospectively analyzed. Results Eight patients with eight lesions were found by colour ultrasound and 10 patients with 10 lesions were observed by ultrasound elastography. The diagnosis accurate rate of ultrasonography was about 72.7% and of ultrasound elastography was about 90.0%. Conclusion US-Elastography is a beneficial addition in diagnosis of thyroid microcacinoma by colour ultrasound. It can remarkably develop the accurate rate of the diagnosis of the disease.
Objective
To discuss the diagnostic and differential diagnostic value of ultrasonography for primary testicular lymphoma (PTL) by studying the ultrasonographical image characteristics.
Methods
Thirty-one patients with PTL confirmed by postoperative histopathology between 2005 and 2015 were chosen to be the study subjects. We retrospectively analyzed their ultrasonographical features and clinical data.
Results
Most PTL patients were elderly men, and the initial symptom was mainly painless testis enlargement. Thirty-nine testicles were involved in the primary testicular lymphoma, including 23 unilateral and 8 bilateral. In the 31 patients, 22 had diffuse lesions and 9 nodal. Ultrasonography showed that most tumors were hypoechoic lesions, and part of them were hyperechoic linearly. The lesions had abundant blood flow signals with a low resistance index.
Conclusions
In elderly patients with painless testicular enlargement, the possibility of primary testicular lymphoma must be fist considered. Manifestations of primary testicular lymphoma have some distinctive characteristics, and combined with clinical history, they are helpful for the diagnosis and differential diagnosis of PTL.
