The difference in MRI expression of the adnexal bone is helpful for differential diagnosis of vertebral myeloma and metastatic tumor.It could provide reliable bases to select therapy.

脊椎骨髓瘤、转移瘤附件骨MRI表现的差异性，有助于对二者的鉴别，为临床治疗方法的选择提供可靠依据。

Methods: CT findings of 131 cavitary metastatic nodules in 40 patients with pathologically-proved pulmonary metastases were retrospectively analyzed.

目的探讨空洞型肺转移瘤的CT表现及其与原发灶病理类型的关系。

Cavitary pulmonary metastases carries certain CT features and its occurrence is related to the pathologic type of the primary malignancy.

结论空洞型肺转移瘤的CT表现具有一定特点，并与原发灶病理类型有关。

The enhanced CT value was found significantly lower in wall of cavitary lung tuberculosis than in the lung cancer,inflammatory lung cavity and lung metastases(P＜0.05),which was 16.8,32.2,28.7,29.4 HU respectively.

5肺结核空洞壁的CT强化幅度明显低于肺癌、炎性肺空洞及肺转移瘤(P＜0.05)，强化值分别为16.8、32.2、28.7、29.4HU。

The distribution was different in various multiple cavitary lung diseases.Local multiple onset was particularly prevalent in cavitary pulmonary tuberculosis,scattered multiple onset was particularly prevalent in various infected cavitary lung diseases,diffuse multiple onset was particularly seen in cavitary pulmonary metastases.

多发性肺空洞病变的肺内分布形式不同，局部多发多见于结核性肺空洞病变，散在多发多见于感染性肺空洞病变，弥漫多发多见于肺转移瘤空洞。

OBJECTIVE: Incidences of cerebroma and brain metastases tumors has been increasing year on year.

目的：脑瘤及脑转移瘤的发病率逐年上升。

However, the recent clinical studies have confirmed that the BBB in patients with cerebroma and brain metastases tumors are at least partially broken down.

但临床研究发现，脑瘤及脑转移瘤患者的血脑屏障的完整性至少被部分破坏。

The imaging manifestation of splenic matastatic tumor is frequently in cystiform.

结果：15例转移瘤均表现为单发或多发低密度灶，囊肿型7例，结节型4例，巨块型4例。

Results The splenic infraction was showed triangular or unr egular low density regions which had no enhancement,Metastasis tumor of spleen had imaged cystiform low density single or several masses,The patho logicai presented little nodular or circle enhancement.Primary lymphoma of spleen had presented part range low density regions and uneven enhancement .

结果 脾梗塞呈三角形或不规则形低密度区，病变无强化；脾转移瘤为囊状低密度肿块，单发或多发，病灶呈小结节状或环形强化；脾原发恶性淋巴瘤，呈局灶性低密度区和不均匀强化。

Results Most of 37 cases located at junctional zone between ectocinerea and alba of cerebrum. Shapes of SBM are multiple, such as node, ring form and cyst-solid node were commonly seen. Most of these were accompanied with marked hydropsia. The degree of hydropsia was related with the site of lesion. Different degree enhancement was showed on enhanced CT in all cases.

结果 单发脑转移瘤病灶多位于大脑灰白质交界区；形态多样，可表现为结节、环形及囊实性不规则形，以结节多见，多伴有明显水肿，水肿程度与解剖部位有关；增强扫描可见不同程度均匀或不均匀强化。

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.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
