However,their echoic characteristics and blood supply are quite different.

结果 前列腺增生、脓肿和癌症三者均可显示前列腺内有结节回声，但结节的回声特点、血流供应情况有所不同。

Results 3 cases were systic masses under nipple tie 4cases were small multi systic masses in the breast gland 7 cases were mixed echoic masses; 5cases were hypo-echoic masses which maintained breast gland structure and 2 cases were hypoechoic masses.

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。

Results High dense renal cyst is usually homogeneous hypoechogenicity on sonograms and homogeneous high/iso attenuation on CT images and color doppler is helpful in diagnosing.Atypical angiomyolipoma usually shows homogeneous high attenuation on unenhanced CT images,homogeneous enhancement on enhanced CT and homogeneous isoechogenicity on sonograms.The CT features of Xanthogranulomatous pyelonephritisinclude multiple,rounded,low density areas with enhancing rings arranged in a hydronephrotic pattern known as bear paw sign.Acute focal bacterial nephritisshows wedge lesion and stripe sign on delayed enhanced CT images.

结果 高密度肾囊肿常表现为B超均匀低回声，CT均质或高密度灶，彩色多普勒超声有助诊断；不典型肾血管肌脂瘤常表现为B超均匀回声，CT平扫均质高密度且均匀强化；黄色肉芽肿性肾盂肾炎的特征是CT示群集的类圆形的低密度区以及环形增强带形成&熊掌征&；急性局限性细菌性肾炎的CT延时增强扫描以及动态观察显示楔形病灶以及条纹征，并随治疗逐渐消退。
