By non-enhancement scan, 12 cases showed low density mass, 4 cases equal density mass, 1 case slightly high density mass, and 2 cases stippled calcification mass. By enhancement scan, 13 cases showed inhomogenous enhancement in cortical phase, 2 cases showed slight to moderate enhancement. Another 2 cases of small cystic RCC presented enhancement of wall with nodules and the partition. The enhancement of all tumor cases faded away in the following parenchymal phase and pyelographic phase, demonstrating some degrees of "fast washing out" phenomenon; 4 cases presented with pseudocapsule. The reconstruction of 17 "MPR/MIP" and 9 "VR" showed clearly the relations of kidney vessels, tumors and neighbor tissues and accessory renal arteries were founded in 2 cases.

结果：17例中小实性肾癌15例，小囊性肾癌2例；CT平扫呈低密度12例，等密度4例，稍高密度1例，伴有斑点状钙化2例；增强扫描皮质期13例呈不均匀明显强化，2例呈轻中度强化，另2例小囊性肾癌的囊壁、壁结节及囊内分隔明显强化；实质期、肾盂期扫描所有肿瘤强化均迅速减退，呈&快进快退&改变；4例可见假包膜。17例MPR/MIP、9例VR重建均能清楚显示肾血管、肿瘤与邻近组织的关系，并发现副肾动脉2例。

Results Among all 25 cases of lymphangioma,Within 20 cases of cystic lymphangioma,single cyst was showed in 14 cases and multilocular cyst was showed in 6 cases in plain scan,and little enhancement of capsule wall and septal in 8 cases in enhancement scanning. Cystic-solid mass was showed in 4 cases of cavernoma lymphangioma in plain scan,and solid part of mass was enhanced obviously in enhancement scanning.1 capillary ymphangioma showed the skin and hypodermic thicking,and part of area showed little beehive-like feature. Enhancement scanning showed slight irregularity enhancement.

结果 25例淋巴管瘤中20例囊性淋巴管瘤，CT平扫14例表现为单一囊肿，6例表现为多房性囊肿，囊腔内见有分隔；增强扫描8例出现囊壁或间隔的轻微强化。4例海绵状淋巴管瘤平扫均表现为囊实性肿块，增强检查实性部分有明显分期增强；1例毛细管型淋巴管瘤表现为局部皮肤及皮下组织的增厚，部分区域见有小蜂房样表现，增强扫描见有轻度不规则强化。

Results All focuses of infection lay in edge of liver,displaying sector sign,sector enhancement,separating enhancement,delayed enhancement and petallike sign were found in turn during arteral phase,venous phase and delayed phase by MR dynamic enhancement scanning.

结果 ①所有病灶均位于肝脏边缘部分；②楔形征像；③在增强扫描的动脉期、静脉期和延迟期分别依次出现楔形强化、分隔状强化和延迟强化、&花瓣&征。
