肝血管瘤3例动脉期瘤内无强化，门静脉期呈向心性填充增强，持续数分钟后消退； 余4例良性病灶变化不典型。
The 3 cases of haemangioma were enhanced centripetally in portal phase and washed out after several minutes without arterial enhancement and the other 4 benign cases without typical enhancement.
结论增强扫描明显均匀强化，且垂体可见，并出现脑膜尾征以及颈内动脉受推压为鞍内脑膜瘤的特征。
Conclusion Homogeneous enhancement, visibility of the pituitary gland, the dural tail sign and compression of the carotid artery are the characteristics of the intrasellar meningioma.
结论使用超声造影剂可明显增强颅内血管信号强度，提高颅内动脉瘤的检出率。
Conclusions Ultrasound contrast agent Levovist improves signal of blood flow obviously. It increases the diagnostic accuracy for intracranial aneurysms and the level of confidence.
目的：增强对颅内巨大血栓性动脉瘤的认识，提高临床诊治水平。
Purpose To add knowledge of the intracranial gigantic thromboaneurysm (IGTA) to clinical doctors and to improve their clinical ability of the diagnosis and treatment.
结论肝内结节超声造影动脉早期快速增强不能确诊为恶性病灶，但结节延迟期仍呈高增强是大多数良性病灶的特征所在。
Conclusion CEUS can rapidly enhance FLL in arterial phase but cannot diagnose it as a malignant tumor. Delayed enhancement of liver nodules is the typical feature of most benign lesions.
