Results An intracerebral echoless cyst could be visualized in all the three cases, in which" high-speed and low-resistance" blood signal could be detected by CDFI. There was direct communication between the vein of Galen and several basis cranii cerebral arteries without cerebral ventricle dilation. The dilated heart-breast rate could be visualized in all the three cases, two of which complicating with the dilation of superior vena cava and tricuspid regurgitation; two of which complicating with pleural fluid and abdominal dropsy; one of which complicating with edema of skin and polyhydramnios; one of which complicating with reversing blood signal of umbilical artery in diastolic phase.

结果 超声声像图显示3例胎儿在丘脑后下方、小脑上方有一无回声囊性结构，彩色多普勒超声提示无回声区内为高速低阻血流信号，与颅底动脉环间可见多条血管分支相通；脑室系统均未见扩大；胎儿心胸比增大，其中2例伴有上腔静脉内径增宽、三尖瓣反流；2例伴有胸腹水，1例全身皮肤水肿伴羊水过多，1例脐动脉舒张期血流反向。

Objective To visualize epicardial and intramyocardial coronary blood flow by using a noninvasive echocardiography system.

目的应用冠脉血流显像技术无创性检测猪冠脉血流，探讨心外膜和心肌内冠状动脉的时相性灌注特点及其在冠脉扩张状态下的变化。

Effects of exercise on cerebral blood flow during 30 d HDT bed rest We observed and compared effects of lower limb muscular exercise with bicycle ergometric exercise during 30 d HDT bed rest on the changes of cerebral blood flow by TCD.

30 d头低位卧床期间体育锻炼对脑血流的影响本实验利用经颅多普勒超声技术观察了30 d -6°HDT卧床期间下肢肌力训练和自行车功量计训练对脑血流的影响。

Methods Color Doppler flow imaging was used to examine the patients with unilateral severe stenosis or obstructive extracranial internal carotid artery.

方法采用彩色多普勒血流成像筛选单侧颈内动脉严重狭窄或闭塞的患者，用TCCS检测颅内主要动脉的血流动力学变化。

The sites headache were lateral or bilateral frontotemporal and parietal, features of pain were blunt and pulsative,last for 15～30 minutes. All the patients had abnormal TCD, 11 cases had increased asymmetric cranial blood flow, 4 cases had decreased brain blood flow.

头痛主要为单侧或双侧额颞、头顶部钝痛或搏动性痛，持续15～30 min.15例患儿TCD检测全部有异常，11例颅内血管呈不对称性血流速度增快，4例血流速度减慢。

Results Image of acute epididymitis and funiculitis displayed in hypoecho and enlarged volume.CDFI display abundant bloodstream,and the blood flow signal obviously reduced after treatment.

结果 附睾炎及精索炎急性期在二维图像上表现为不同程度的低回声水肿、体积增大，彩色多普勒显示血供丰富等血流动力学改变，治疗后血流明显减少。

结果 附睾炎及精索炎急性期在二维图像上表现不同程度的低回声水肿、体积增，彩色多普勒显示血供丰富等血流动力学改变，治疗后血流明显减少。

This flap is supplied by the retrograde flow of the saphenous artery via communication mainly with the medial inferior genicular artery.

这个皮瓣的血流功能是隐动脉的逆行性血流－主要来自与内下膝动脉的交通。

Results The increased percentage of the brachial artery diameter and blood flow velocity at hyperemic condition was lower in patients with CHD than that in normal controls. However,there was no significant difference in response to nitroglycerin between the CHD patients and the normal controls.

结果 CHD患者肱动脉加压前后的血管直径和血流速度变化百分比明显小于正常对照组；而舌下含服硝酸甘油前后肱动脉内径及血流速度变化百分比在两组之间无明显差异。

Results The artery frequency spectrum of high speed and low resistance were found in malignant trophoblastic tumors. The ulterine muscular layer in malignant trophoblastic tumor was hypervascular and the resistive index was less than 0.4. After chemotherapy, the hypervascularity decreased, RI increased higher, and β-HCG returned normal.

结果 恶性滋养细胞肿瘤子宫动脉RI值较低，为高速低阻力性动脉频谱；恶性滋养细胞肿瘤宫壁血流异常丰富，子宫肌层病灶内血管阻力指数RI.4；恶性滋养细胞肿瘤患者全身化疗取得疗效后子宫肌层血流丰富区逐渐缩小，RI呈逐渐升高趋势，血β-HCG逐渐恢复正常。
