【摘要】 目的 用高頻超聲對正常女性乳腺健康體檢,探討其在臨床及乳腺普查方面的應用價值。 方法 對2006年1月-2009年12月間7 532例健康女性乳腺體檢聲像圖進行分析,并對各年齡段的乳腺病變超聲結果分布情況進行統計。 結果 共檢出乳腺病變2 861例(37.98%),正常者4 671例(62.02%)。所有受檢者中,囊性病變1 904例(25.28%),實性病變944 例(12.53%),混合性病變13例(0.17%),伴有副乳者692例。囊性病變及實性病變單側多于雙側,混合性病變均為單側。常見病中,囊性病變多于實性病變,發病年齡分布在20~30歲及31~40歲年齡段。 結論 高頻超聲作為女性乳腺疾病的一種常規檢查,能對乳腺占位性疾病提供較為準確的診斷,對乳腺癌早期發現、早期診斷、早期治療提供一種科學依據。【Abstract】 Objective To explore the clinical value of high-frequency sonography for normal clinical breast examination in breast screening. Methods From January 2006 to December 2009, 7 532 healthy women underwent breast sonography. The results of sonography in the individuals with different ages were statistically analyzed. Results Breast lesions were found in 2 861 cases (37.98%) and the other 4 671 were healthy. Among all of the individuals, 1 904 cases (25.28%) had cystic lesions, 944 (12.53%) had solid lesions and 13 (0.17%) had mixed lesions. There were 692 cases of accessory mammary tissue. Unilateral cystic nodules and solid nodules were more common than bilateral ones, whereas mixed nodules were usually sunilaterally. Cystic nodules were more common than solid nodules. Most common onset of breast lesions is in the individuals with the age of 20-30 and 31-40 years. Conclusion High-frequency sonography, as an examination for normal clinical breast screening provides more accurate diagnosis and early detection of breast lesions, which can provide scientific evidence for early detection, diagnosis and treatment for breast cancer.
【摘要】 目的 比較腸充盈超聲檢查法與常規經腹超聲檢查法在結直腸腫瘤中的診斷價值。 方法 對2008年6月-2009年6月64例經臨床病理確診的結直腸腫瘤患者分別經腹常規超聲及腸充盈超聲檢查。在腸充盈狀態下觀察病變的形態,對病變進行定位并觀察結直腸腫瘤的彩色多普勒血流信號。比較腸充盈超聲檢查法及常規經腹超聲檢查法在結直腸腫瘤的檢出、定位和顯示血流的能力的差異。 結果 常規經腹部超聲檢查發現32例結直腸腫瘤(32/64),病灶敏感性為50%; 腸充盈超聲檢查法發現病灶55例(55/64), 病灶敏感性為85.9%。經腹常規超聲檢查的定位準確率為21.9%(7/32),腸充盈超聲檢查法對結直腸腫瘤的定位準確率為89.1%(49/55)。兩種方法比較差異有統計學的意義(Plt;0.05)。 結論 腸充盈超聲檢查法在結直腸腫瘤的病變敏感性檢出、定位準確性等方面優于經腹常規超聲檢查;而不同病理類型的結直腸腫瘤具有不同的超聲聲像圖特征。【Abstract】 Objective To compare the diagnostic value between intraluminal contrast-enhanced hydrocolon ultrasonography and conventional transabdominal ultrasonography for of colorectal neoplasms. Methods The conventional transabdominal ultrasonography and hydrocolonic ultrasonography using an intraluminal contrast agent were performed on 62 patients from June 2008 to June 2009. The morphological features and location of the lesion were observed and the blood flow signals were observed. The different diagnostic value between conventional transabdominal ultrasonography and intraluminal contrast-enhanced hydrocolon ultrasonography was compared. Results The sensitivity of the intraluminal contrast-enhanced hydrocolon ultrasonography in the depiction of the colorectal neoplasms (55/64, 85.9%) was higher than that of the conventional transabdominal ultrasonography (32/64, 50%, Plt;0.05). And the accuracy of the intraluminal contrast-enhanced hydrocolon ultrasonography in locating the colorectal neoplasms (48/55, 87.3%) was higher than that of the conventional transabdominal ultrasonography (7/32, 53.2%, Plt;0.05). Conclusion Intraluminal contrast-enhanced hydrocolon ultrasonography is more valuable for colorectal neoplasms than conventional transabdominal ultrasonography in detecting and locating colorectal neoplasms. Colorectal neoplasms with different pathological types may have different ultrasonic features.
【摘要】 目的 探討腎上腺髓樣脂肪瘤的彩色多普勒超聲表現和超聲診斷價值。 方法 回顧性分析2005年3月-2010年9月58例61個經手術及病理證實的腎上腺髓脂肪瘤病灶的彩色多普勒超聲表現,對病變的大小、內部回聲特點及血流特點進行分析。 結果 在2005年3月-2007年12月的28個病灶超聲診斷出腎上腺病變23個,正確率82.1%;診斷為髓脂肪瘤2個,正確率7.1%;漏診1個,誤診4個。2008年1月-2010年9月,33個病灶超聲診斷出腎上腺病變30個,正確率90.9%;診斷為髓脂肪瘤19個,正確率57.6%;無漏診,誤診3個。52個病灶超聲表現為邊界清晰,形態基本規則,內部呈均勻中等強回聲(與腎集合系統回聲相當),內部未測及血流信號, 另8個病灶表現為中等強回聲與低回聲相間。 結論 腎上腺髓樣脂肪瘤具有特征性的彩色多普勒超聲聲像圖表現, 可用于發現病變并對多數腎上腺髓樣脂肪瘤做出定性診斷。【Abstract】 Objective To evaluate the value of sonographic diagnosis of adrenal myelolipoma. Methods Sonographic findings from 58 patients with pathologically proved adrenal myelolipoma from March 2005 to September 2010 were retrospectively analyzed. The size of the lesion, internal echo features, and characteristics of blood flow were observed and analyzed. Results In 28 patients with pathologically proved adrenal myelolipoma from March 2005 to December 2007, adrenal lesions was diagnosed in 23 with an accurate rate of 82.1%; adrenal myelolipoma was diagnosed in two with an accurate rate of 7.1%; missed diagnosed in one; misdiagnosed was in four. In 33 patients with pathologically proved adrenal myelolipoma from January 2008 to September 2010, adrenal lesions was diagnosed in 30 with an accurate rate of 90.9%; adrenal myelolipoma was diagnosed in 19 with an accurate rate of 57.6%; no missed diagnosed occurred; misdiagnosed was in three. The sonographic features in 52 lesions were smooth borders and homogeneous hyperechoic; no color Doppler flow signal inside was detected. Conclusion Adrenal myelolipoma has special sonographic features. Ultrasonography is a reliable imaging method for the diagnosis of adrenal myelolipoma.
