病灶

In the vertebrobasilar system, however, breakthrough of autoregulation occurs because of sparse sympathetic innervation.

但在椎基底动脉系统，由于交感神经分布稀疏，血压过高超过血管自身调节的极限时，常导致枕叶病灶的出现。

Objective To investigate the MRI features of patients with top of basilar syndrome.

目的总结基底动脉尖综合征患者的MRI病灶分布特征，以期加强对该病的认识。

Results The compounded gum was combined with bletilla hyacinthine gum and PVA in the proportion of 5:1 so that its adhesive ability and membrane forming ability were suitable for giving medicine through airway.

在临床工作中，由于全身用药对肺局限性病灶常存在穿透力不够而在局部无法达到有效浓度的情况，往往需要采用从气道内直接给药的方法，如厚壁结核空洞、局灶性化脓性病变等[1 ] 。

Results None of the 19 patients had history of exposure to asbestos. Eight cases(42.1%) had no obvious thoracodynia, 9 cases(47.4%) had pleural effusion limited to the right chest, and in 2 cases(10.5%) the brachialis plexus was involved, and in 1 case (5.3%) malignant mesothelial cells were detected in the pleural effusion. Pleural thickening or nodules were found in 13 cases on CT and in 9 cases by B ultrasonographic examination.

结果 19例患者均无明确石棉接触史；8例（42.1％）无明显胸痛；9例（47.4％）单纯右侧胸腔积液；2例（10.5％）臂丛神经受影响；1例（5.26％）胸水中查到恶性间皮细胞；9例（47.4％）B超检查发现胸膜肥厚或结节；13例68.4％）CT检查发现胸膜结节状病灶。

HRCT(high resolution computed tomography) at present has been the perfect technique of CT in the spatial and contrast resodution and the best imaging method of assessments of small sati solitary nodular lesions and bronchiolar diseases in the lungs.

高分辨率 CT目前是一种使空间和密度分辨率尽可能完善的 CT技术，是当今评价肺内小结节性病灶和细支气管疾病最理想的影像方法。

A minimally invasive reflective array, tool navigator, and a registered burr were used for localization and deroofing of the lesion, followed by curettage and highspeed burring of the cavity.

运用微创反射阵列、导航工具和校正钻孔器进行定位，然后肿瘤去顶、刮除、高速磨光病灶腔。

Mature type VI lesions exhibit architecture that is more complicated and characterized by calcified fibrous areas with visible ulceration.

成熟期的第六型病灶呈现更复杂的架构，其特徵为：有明显溃疡的钙化纤维区域。

MRI is the main method for the detection of vascular lesions of the corpus callosal.

胼胝体梗死并不少见，其临床表现常被合并的梗死病灶所掩盖，MRI是确诊的主要依据。

Stenosis of internal caroid antery was found in 32 of 48 branches in 24 case. 5 branches were occlusive and 11 branches were normal. 22 cases with large or moderate cerebral infarction volume （＞5 cm3） confirmed by CT and MRI were smaller than those on MSCTPI as having abnormal perfusion lesions,which were moderate and obvious stenosis and occlusion on MSCTA. In 2 cases with small cerebral infarction volume（＜5 cm3）, MSCTPI and MSCTA revealed normal.

其中32支颈内动脉呈不同程度的狭窄，5支颈内动脉闭塞，11支血管无狭窄。22例在常规CT及MRI图像上为中及大体积梗死（＞5 cm3）的患者，MSCTPI发现与梗死灶相对应的异常灌注区，且均比常规CT及MRI图像上病灶体积大， MSCTA显示颈内动脉呈中重度狭窄或闭塞。2例未发现明显灌注异常的患者，为小体积梗死灶（＜5 cm3），MSCTA显示颈内动脉正常。
