子宮峽部剖宮產切口部位妊娠的彩色多普勒超聲診斷分析

目的探討子宮峽部剖宮產切口部位妊娠的彩色多普勒超聲聲像圖特點，為臨床診療提供有價值的參考依據。 方法選取2011年8月－2013年7月診斷的12 例子宮峽部剖宮產切口部位妊娠的患者作為研究對象，回顧性分析其彩色多普勒超聲聲像圖特點及臨床資料。 結果12例患者中5例停經時間短、妊娠囊較小，位置完全位于子宮峽部切口處因聲像圖典型而確診；3例因停經時間長、妊娠囊大部分位于宮腔內，少部分位于切口處誤診為宮內孕；2例切口妊娠流產，誤診不全流產；另外2例因院外人工流產術后陰道流血增多就診，診斷為切口妊娠。 結論彩色多普勒超聲對子宮峽部剖宮產切口妊娠的診斷具有準確性、可靠性。

Comparative Study on Breast Imaging Diagnostic Methods of Commonly Used

【Abstract】　Objective　To compare the accuracy of color-doppler ultrasonography, mammography and near-infrared light scanning for diagnosing breast diseases. Methods　The diagnostic accuracy of the above three imaging methods were analyzed and compared with each other on the basis of the postoperative pathological results. ResultsFive hundreds and sixty-five cases (breast cancer: 274 cases, benign diseases: 291 cases) were examined. The sensitivity of color-doppler ultrasonography, mammography and near-infrared light scanning for diagnosing breast cancer were 83.7%(200/239), 84.2%(64/76) and 76.9%(100/130), respectively. The specificity were 88.6%(226/255), 93.2%(69/74) and 82.6%(114/138), and the accuracy were 86.2%(426/494), 88.7%(133/150) and 79.9%(214/268), respectively. Color-doppler ultrasonography and mammography were superior to near-infrared light in the item of accuracy (P＜0.05), especially for lesions of breast cancers that were less than 2 cm. The false negative rate of near-infrared light was higher (48.8%, 21/43）than those of the other methods in detecting breast cancer at early stage. The sensitivity for detecting intraductal papilloma and inflammation of breast using color-doppler ultrasonography were 58.8%(10/17) and 69.2%(18/26), respectively, which were higher than that of near-infrared light scanning 〔0 and 23.5%(4/17)， P＜0.05 and P＜0.01〕. The sensitivity and the accuracy of near-infrared light without physical examination reduced significantly, in which the sensitivity reduced from 76.9%(100/130) to 56.9%(74/130), P＜0.01, and the accuracy reduced from 79.9%(214/298) to 61.9%(166/268), P＜0.01. Conclusion　Color-doppler ultrasonography and mammography are accurate imaging methods for diagnosing breast diseases.

Study on Evaluation of Hemodynamic Changes of Portal Veins in Patients with Liver Cirrhosis by Color Doppler

目的　分析彩色多普勒超聲對肝硬化患者門靜脈血流改變的評價作用。 方法　選擇2010年1月－2011年4月收治的50例肝硬化患者作為觀察組，其中代償期患者27例，失代償期患者23例；同時設置健康對照組50名，比較兩組的門靜脈內徑（Dpv）、門靜脈平均血流速度（Vpv）、門靜脈血流量（Qpv）。 結果　觀察組患者的Dpv增寬，Vpv減慢，Qpv減少，與對照組比較，差異均有統計學意義（P＜0.05）；且失代償期患者的改變更為明顯，與代償期患者間差異有統計學意義（P＜0.05）。 結論　彩色多普勒超聲檢查門靜脈血流改變可以對肝硬化患者進行初步確診。

視網膜母細胞瘤的彩色多普勒超聲診斷分析

膝、腕關節滑膜超聲在類風濕關節炎中的臨床價值比較

摘要:目的:探討類風濕性關節炎(RA)病人膝、腕關節滑膜關節滑膜的超聲檢查指標與RA臨床指標的相關性。方法:通過高頻超聲及彩色多普勒超聲對RA病人(50 例)的膝、腕關節的滑膜情況(包括滑膜厚度、關節積液程度、滑膜彩色血流分級)進行觀察,并獲取RA患者疾病活動度(DAS28)分值、炎癥指標C反應蛋白(CRP)、紅細胞沉降率(ESR)、標記性抗體抗瓜氨酸抗體(CCP)和類風濕因子(RF)滴度水平并對上述指標做相關分析。結果:①RA病人膝關節滑膜厚度、關節積液程度、滑膜血流信號分級等級與患者DAS28(r=0.35、r=0.38、rs =0.54,Plt;0.05)、CRP(r=0.41、r=0.45、rs =0.57,Plt;0.05)、ESR(r=0.38、r=0.42、rs=0.51,Plt;0.05)均呈正相關;腕關節滑膜厚度、滑膜血流等級信號與患者DAS28(r=0.55、rs=0.69,Plt;0.05)、CRP(r=0.53、rs =0.67,Plt;0.05)、ESR(r=0.48、rs=061,Plt;0.05)均呈正相關,且相關系數高于膝關節組;②膝關節組滑膜厚度與關節積液程度、滑膜血流分級等級均呈正相關(Plt;0.05),關節積液程度與滑膜血流分級呈正相關(Plt;0.05);腕關節組滑膜厚度與滑膜血流分級等級均呈正相關(Plt;0.05);③膝、腕關節之間僅滑膜血流信號等級成等級正相關(Plt;0.05)。結論:膝、腕關節滑膜超聲能較好地觀察類風濕性關節炎病人滑膜的病變,其指標能作為一種客觀有效的評價療效、判斷疾病活躍性及評估預后的指標,尤其應該以腕關節作為RA病人的優選關節。

Ultrasonographic features of gastrointestinal stromal tumors

Objective To analyze features of color Doppler ultrasonography in gastrointestinal stromal tumors. Method The ultrasound images of gastrointestinal stromal tumors (51 cases) and gastrointestinal cancers (59 cases) confirmed by operation and pathology were compared and analyzed. Results The gastric stromal tumor mainly occurred at the bottom of the stomach and the body of the stomach (17 cases), the intestinal stromal tumor mainly occurred at the small intestine (24 cases). The gastric cancer mainly occurred at the gastric antrum (18 cases), the intestinal cancer all occurred at the colon (20 cases) and rectum (12 cases). Compared with the gastrointestinal cancers, the gastrointestinal cavity was not surrounded by tumor, the peripheral boundary was clear, the morphology was more regular, the internal echo was uneven, and there was no peripheral lymph node metastasis in the gastrointestinal stromal tumors, the differences were statistically significant (P<0.05). There were no significant differences in the degree of blood flow and tumor diameter between the gastrointestinal stromal tumors and the gastrointestinal cancers (P>0.05), but the blood flow of the intestinal stromal tumor was significantly more abundant as compared with the intestinal cancer (P<0.05). Conclusion Color Doppler ultrasonography, as a simple and rapid method, has a certain diagnostic value for differentiation of gastrointestinal stromal tumors and gastrointestinal cancers.

彩色多普勒在眼科的應用進展 

眼血流測定在眼部多種疾病的研究中得到越來越多的應用。彩色多普勒成像（CDI）技術可檢測眼球后部血管的位置、血流方向和流速，為研究眼球的組織結構、眼球后血流動力學特征以及病理狀態下的改變和臨床療效觀察提供了一種簡便、直觀、無創、可重復、可連續動態觀察的檢查方法。對眼部血管性疾病和腫瘤的診斷與鑒別診斷有重要價值。現就CDI在青光眼、脈絡膜和視網膜循環性疾病、眼內和眼眶占位性疾病中的應用進展綜述如下。 (中華眼底病雜志,2005,21:134-136)
