【摘要】 目的 探討高頻彩色多普勒超聲對淺表軟組織腫物的診斷價值。 方法 回顧性分析2008年1-11月70例經手術、活檢病理證實的淺表軟組織腫物的聲像圖特征，包括腫物的部位、形態大小、內部回聲、邊界及其與周邊組織的關系、長徑與厚度比值（L/T）及病變周邊與內部血流分布情況。 結果 超聲對淺表腫塊病灶的顯示率為100%，良性腫瘤有脂肪瘤、表皮囊腫、滑膜囊腫、神經鞘瘤，血管瘤、異物肉芽腫等，惡性腫物包括皮膚纖維肉瘤，轉移性腺癌。 結論 彩色多普勒超聲對淺表腫塊的檢出、定位及物理性質可做出準確的診斷，綜合分析腫物的邊界、形態、內部回聲及血流分布等特點對腫物的良惡性診斷具有重要價值。【Abstract】 Objective To evaluate the value of high-frequency color Doppler ultrasonography in diagnosing the superficial soft tissue masses. Methods The clinical data of 70 patients with superficial soft tissue masses from January to November 2008 were retrospectively analyzed. Superficial soft tissue masses was diagnosed by the surgery and biopsy. The sonographic features, including the location, morphology, size, internal echo, boundary, relationship with peripheral tissues, longitude to transverse ratio (L/T), and the vascularity, were observed. Results The results of sonographic examination showed that 100% superficial masses could be found. Benign masses included lipoma, sebaceous cysts, synovial cysts, nerve sheath tumors, haemangioma, foreign body granulomas, etc. Malignant soft tissue tumors included fibrous sarcoma and metastatic neoplasms. Conclusion Color Doppler ultrasonography can precisely diagnose the presence, localization and the physical characters of superficial soft tissue masses. It is an excellent modality to diagnose the benign or malignant masses by analyzing the boundary, configuration, internal echo and vascularity of the masses.
【摘要】 目的 探討彩色多普勒超聲對臨床甲狀腺良惡性結節的診斷價值。 方法 對2007-2010年105例經手術病理證實的甲狀腺結節患者資料進行回顧性分析，總結其聲像圖特征。 結果 105例患者中，良性結節71例，甲狀腺癌34例，超聲診斷符合率81.9%，誤診18例（17.1%）。 結論 彩色多普勒超聲是診斷甲狀腺結節的首選影像學檢查方法，但對良惡性結節的鑒別及微小癌的診斷有局限性。【Abstract】 Objective To evaluate the value of color Doppler flow imaging in diagnosis of benign and malignant thyroid nodules. Methods We retrospectively analyzed the clinical data of 105 patients with thyroid nodules confirmed by pathology between 2007 and 2010 and summarized the ultrasonography results. Results Among the 105 cases, 71 were benign nodules and 34 were malignant tumors. The overall diagnostic accordance rate was 81.9% with 18 cases (17.1%) of misdiagnosis. Conclusion Ultrasonography is the first imaging modality for thyroid nodule examination, but it is limited in the diagnosis of microcarcinoma and in distinguishing malignant from benign nodules in the same thyroid.
