Results The lesion located at the basal segments of left lower lobe in 9 cases (90%), furthermore, 7(70%) at the posterior basal segments; The remainder 1 case (10%) was found at the posterior basal segment of right lower lobe; The lesion present as multiloculated cyst containing fluid and/or air in 7 cases(70%) without contrast enhancement of cyst wall, 3 cases (30%) presented as irregular mass with moderate enhancement, in which bronchiectasis with mucous impaction, calcification or cyst containing fluid may be seen; MRP, MIP and VR reconstructions showed anomalous branches arising from descending aorta in all 10 patients(100%) with draining into left atrium via pulmonary vein,which was consistent with surgery; Ipsilateral hilar lymphadenopathy was demonstrated in 7 cases (70%).

结果 9例（90％）病灶位于左下叶基底段，其中7例（70％）位于左下叶后基底段，1例（10％）位于右下叶后基底段；7例（70％）病灶表现为含液/气的薄壁多房囊腔，增强后囊壁无明显强化，3例（30％）表现为不规则团块，增强后有中等强化，其内有粘液嵌塞的扩张支气管，也可有钙化或液性区；MPR、MIP及VR等三维重建显示10例（100％）均为降主动脉发出异常分支供血，并通过肺静脉回流入左房，血管显示情况与手术相符；7例（70％）患侧肺门淋巴结有增大。

Results Ureteral calculuses were showed as high density image in CT scanning.The CT values of the ureteral calculuses less than 7.5mm in diameter were beyond 83HU.The detection rate by CT was 96.3%.In all the 82 cases,ureteral with calculuses were found dilated and 69 cases with nephrohydrosis.

结果 输尿管膀胱入口处结石具有特征性的CT表现，即圆形或枣核状钙化高密度影，结石直径＜7.5mm，CT值≥83HU，CT确诊率96.3%。82例均发现病侧输尿管增粗，69例发现病侧肾盂少量积水，肾盂未见积水的输尿管膀胱入口处结石13例，其结石直径＜3.8mm。

Single-location enhancement is of great importance in differentiating benign and malignant pulmonary nodules, especially in noncalcified pulmonary carcinoma and tuberculoma. It can improve the accuracy of diagnose of pulmonary carcinoma significantly.

同层动态CT增强扫描技术对良、恶性肺结节，尤其是非钙化性肺癌与肺结核瘤的鉴别诊断作用较大，可明显提高肺癌性结节的定性准确率。

This popcorn appearance is almost pathognomonic; other patterns of calcification include curvilinear and stippled.

这种爆米花样表现是病例特征性的，其他的钙化方式包括曲线形和斑点形。

Initial imaging modality is typically CT in a postepileptic patient. Findings include increased density in a periventricular distribution without enhancement or calcification.

癫痫后的病人，最初的影像检查往往是CT，影像表现包括室周区域密度增高，不伴有强化或钙化。

Diffuse, tiny punctate calcified spots within the tumor were well demonstrated on CT and ultrasound, which have not been seen in most DSCTs reported before.

同时在电脑断层及超音波下可见到肿瘤内部有明显的散布性点状钙化，该项发现极少见於以前的病例报告中。

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。

In this paper, the process of the cleaner roasting of shaly coal was studied.

本研究对石煤清洁焙烧工艺进行了研究，发现钙化焙烧除可完全避免钠化焙烧过程中Cl2 、HCl等有害气体的产生外，石灰在焙烧过程中有很好的固硫效果。

Ten cases which were first found showed regular oval shape, 4 of 5 recurred lesions appeared as irregular shape. On bone algorithm reconstruction of CT, 11 lesions revealed heterogenous "ground-glass like" mild hyperdensity or hyperdensity masses compared with brain tissue with cystic areas, stippled calfication was seen in 1 cases, the typical eggshell like bony capsule in 7 cases, 5 cases under it showed ring or arc hypodensity line.
