Objective:Patterns of blood flow supply of 75 cases with hepatocellular carcinoma(105 lesions)and 54 cases with liver metastatic cancer(96 lesions)were analysed by color Doppler flow imaging to tender for diagnosis and differentiation diagnosis evidences.Methods:The hemodynamics parameter of the proper hepatic artery,the portal vein and the feeding vessels for tumor were presented by color Doppler spectrum.The measurement indexes are the maximum blood flow velocity(V max),the resistance index(RI),the pulsatility index(PI),the ratio of the maximum to minimum blood flow velocity(A/B)and the blood flow volume(FV).Results:The Vmax and FV of the proper hepatic artery and portal vein of the hepatocellular carcinoma(HCC) and liver metastatic cancer(LMC)group were higher than normal control group( P <0 001),however,the RI,PI and A/B ratio of the proper hepatic artery were lower than normal control.Pulsatory blood flow signals within the tumor were observed in HCC 82(91 1%)and “basket”pattern was found in 65(72 2%).The lesions of LMC showed mainly periphery flow pattern around tumor.Conclusion:Color Doppler flow imaging can improve accuracy of diagnosis and differentiation of HCC from LMC,but it is unreliable in deffrentiation of HCC from hypervascular LMC.

Objective To study the change of Doppler spectrum caused by venogenic impotence. Methods 32 cases were venogenic impotence. 85 cases with psychological impotence were served as control group. All cases were examined using duplex ultrasound (Biosound - AU4 USA) after intracavernous injection of vasodilator. Results Doppler spectrum suggested a forward flow during full diastole or early- middle diastole in cavernous arteries and also suggested persistent flow of deep dorsal vein in patients...

Objective:To investigate the role of high frequency and color Doppler ultrasonography in the diagnosis of mammary intraductal papilloma.Methods: A retrospective analysis was performed,which included the database of sonography and color Doppler spectrum of 54 patients with mammary intraductal papilloma. Mammary intraductal papilloma was verified by the operation and histopathological examinations.Results:The sonography of 54 patients with mammary intraducal papilloma were divided into 4 types:35 cases shown duct dilatation with papillary processes,4 cases shown irregular sonolucent areas with solid echogenitic masses, 6 cases shown duct dilatation, and 9 cases shown solid masses. The diagnostic accuracy of ultrasound examinations was 72.2% . The difference was not significant for color Doppler ultrasonography in the differential diagnosis between benign and malignant intraductal papilloma.Conclusions:High frequency and color Doppler sonography can demonstrate direct or indirect sonographic characteristics of mammary intraductal papilloma. It is one of effective diagnostic tools in the diagnosis of such disease.

目的探讨高频彩色多普勒超声对乳腺导管内乳头状瘤的诊断价值。方法回顾性分析54例经手术和病理学证实的乳腺导管内乳头状瘤的声像特征和彩色多普勒频谱表现。结果54例乳腺导管内乳头状瘤的声像图特征可分为4型。导管扩张伴导管内乳头状回声型35例,不规则液性暗区中实质回声型4例,单纯性导管扩张型6例,实质结节回声型9例。超声诊断符合率为72.2%。彩色血流和多普勒频谱对导管内乳头状瘤良、恶性病变的鉴别无显著差异性。结论高频彩色多普勒超声能显示乳腺导管内乳头状瘤的直接或间接声像特征,是诊断该病的一种有效检测方法。
