小结节

Results (1) 6 cases of Tuberous Sclerosis. Diffused subependymal nodular calcification lesions were found in all cases on unenhenced CT. 4 patients are 2 pairs of mother/child relationship. Both of the two mothers are found to suffer from renal angiomyolipoma.(2)1 case of neurofibromatosis showed abnormal spinal canal: scoliosis of thoracic and lumbar spine, concave change of vertebral posterior border. Bilateral renal hypogenesis was found in this patient. Diffused hyper-density lesions were found in kidney and fatty accumulation was found in back skin.(3)6 cases of Sturge-Weber syndrome. On unenhenced CT, curving and strip-shaped calcifications were found along the parietal and occipital gyrus.

结果 ①结节性硬化6例，所有病例CT平扫见两侧脑室室管膜下多发小结节状高密度钙化灶，其中4例为两对母子关系，并见两位母亲合并有肾脏错构瘤，；②神经纤维瘤病1例，MRI表现为椎管异常，胸腰段脊柱侧弯，椎体后缘呈明显的切凹改变；伴有双肾发育不良，CT示肾内多个高密度影，背部皮肤多量脂肪堆积，③脑颜面血管瘤综合征6例， CT可见顶枕部沿脑回分布的弯曲的条状高密度钙化，部分延伸致侧脑室内，增强后见病灶内有扭曲的条状和结节状明显强化的血管影；④小脑血管瘤病4例，影像学表现为小脑内大囊、小结节样占位性病变。

Objective To evaluate the diagnostic value of Isotropic Scanning in Small Pulmonary Nodules,and to improve diagnostic level.

目的 评估各向同性重建对肺孤立结节性病变的诊断价值，提高小结节的诊断水平。

Abstract］ objective to study the knowledge of the imaging manifestation of x-ray and ct in peripheral small lung cancer.methods to collect twenty cases with no symptom in early time diagnosed by clinic and to retrospectively analyze their imaging features.results x-ray appeared patch,small node.ct appeared patch,small node,light lobulation,peripheral vessel convergence,pleural indentation sign.most of the diameter was 1.5 to 2 cm,with no mediastinum and pulmonary hilar lymph nodes diversion.furthermore the clinical symptom was not obviously.conclusion to be familiar and handling the sign mentioned above is the key to boost the diagnosis of small peripheral lung cancer.

目的 探讨周围型小肺癌的x线、ct影像学表现。方法收集临床和病理证实的早期无症状肺癌20例，对其影像学进行回顾分析。结果本组早期肺癌x线为斑片状、小结节状。ct表现为斑片状、小结节状、轻度分叶状肿块，小毛刺、血管集束征、胸膜凹陷征，大多直径在1.5～2 cm。无纵隔淋巴及肺门转移，且临床症状不明显。结论熟悉并掌握上述征象是提高小肺癌早期诊断率的关键。

All aforementioned cases entierely were proved pathological diagnosis using operation or lung centesis. Results: On the CT manifestation, lobulation sign and spiculation sign mostly appeared in the malignant nodules. The accurate rate of diagnosis was 75.6; sensitivity were 76.3%; specificity were 74.1%; positive predictive value were 86.5%; negative predictive value were 58.8%.

结果：86例SPN的Cr征象中，分叶征和棘突或毛刺征多出现于恶性结节，与病理和随访结果对比，螺旋CT薄层扫描并MPVR重建判断肺小结节良恶性的准确率、灵敏度、特异性、阳性预测值和阴性预测值分别为75.6%、76.3%、74.1%、86.5%、58.8%。

CT of lung show diffused distribution of plaque and spottiness with high density cavity with inequlity of size and ellipse nodus with sharpness edge and high density. Cases received treatment with Amphotercin B combination fluconazol by vein and intrathecal injection of Amphotercin B.Five cases were cured and five were improved.

5胸片表现为两肺散在分布小片状、小结节阴影，边缘模糊、内见不规则低密度区；CT示两肺广泛分布斑片状和斑点状密度增高影、大小不等的空洞或类圆形边缘光滑高密度结节。

He considered four segments of the proximal humerus - the articular part, the greater tuberosity, the lesser tuberosity and the humeral shaft - that might be fractured off and displaced from each other.

他认为，肱骨近端分为四部分——关节部分，大结节，小结节和肱骨干。这几个部分可能骨折、移位。

All cases of X-ray signs included small node 8 cases,mass with spiculate border and lobulate margins 20 cases,cluster microcalcification 26 cases,structure tortuosity disorder 10 cases,small laminated density markup 7 cases,the partial blood vessel increases thickly 3 cases,4 cases with normal digital mammography which were done by color ultra promptly,low echo tubercle were confirmed for breast cancer by instrument.

其中8例呈小结节影，20例呈肿块伴有毛刺样改变或呈分叶状，26例仅有成簇细小点状钙化，10例局部结构扭曲紊乱，7例局限性小片状密度增高，3例表现为局部血管增多增粗，4例患者彩超提示低回声结节，数字钼靶未发现明显病变，经穿刺活检证实为乳腺癌。

Results: Forty- four nodules were available for final evaluation. Average nodule volume was 501.9 mm3(range,17mm3～2496.4mm3).Thirty-two nodules had well-defined edges, and 12 had irregular or spiculated margins.

结果： 44个结节作为最终体积测量对象，肺小结节体积变化范围17 mm3～2496.4 mm3 ，平均值为501.9 mm3.32个结节边缘光滑，12个边缘不规则或呈针尖状。31个结节位于肺实质内，9个靠近胸膜，4个邻近血管。41个呈实性未见钙化，2个斑点状钙化，1个完全钙化。

The characteristics of typical pattern of MF infection are nodular granulomas or diffuse inflammation with mixed granulomas which con-sisted of central abscesses surrounded by epithelioid and giant cells,abundant vacuole zosters or ring structures(lipid-like struc-tures) around the necrotic lesions and small granulomatous nodules.

结节性或弥漫性炎症伴混合性肉芽肿(中央为脓肿围绕着上皮样细胞及巨细胞)以及坏死灶及肉芽肿样小结节周围出现大量空泡细胞条带或环状结构为偶发分枝杆菌感染的最典型表现形式。

Results rolls the massive sphere focus of infection altogether 25 examples (9 examples to have "crecent moon to draft", 8 examples have "air bronchial tube to draft", 5 example edges have "burr to draft", 3 examples have "corona to draft").the double lung spot punctual subtotal nodular focus of infection altogether 15 examples, in 13 example tubercle shade the small cavity, the pulmonary abscess type changes the l example obviously.big laminated consolidation 3 examples.the mediastinum lymph node increases the partner chest cavity or the pericardium accumulates the fluid l example.

结果：团块状球形病灶共25例(其中9例有&新月征&，8例有&空气支气管征&，5例边缘有&毛刺征&，3例有&晕征&)。两肺斑点状小结节状病灶共15例、其中13例结节影内可见小空洞，肺脓肿样改变1例，大片状实变3例。纵隔淋巴结增大伴胸腔或心包积液1例。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
