According to the pathological features , we can divide tumors into two categories : benignancy and malignancy .

根据病理学特征，可以分为良性和恶性两类。

5CER acts as an index of distinguishing malignancy or benignancy, the value of 5CER in malignant is more than 10% and in benignant is less than 10%.

以5CER作为区分良恶性病变的指标，5CER≥10%为恶性5CER0%为良性。

On the other hand, the difference between the benignancy and the malignancy is successfully identified by DFVI（p=0.004, sensitivity 84%, specificity 64%） because of the protruded microcirculation among thyroid tumor tissue.

本文透过动态影像处理后的DFVI具有良好的检测能力（P=0.004 Sensitivity 84% Specificity 64%），其中主要的关键在於DFVI能够凸显较末端微循环特性。

The recognition of this entity is of great importance to both pathologists and clinicians because atypical cellular neurofibroma is clever at masquerading both histologically and cytologically as a sarcoma; therefore, a precise diagnosis of this variant is essential because of the differences in treatment and clinical behavior between benignancy and malignancy.

对於病理医师和临床医师来说，区分出这个纤维神经瘤的变异型非常重要，因为异生细胞纤维神经瘤在组识学上和细胞学上都非常类似肉瘤，因此正确的诊断出这个纤维神经瘤的变异型是必要的，因为临床上对於良性和恶性肿瘤的治疗和肿瘤行为表现是不同的。

The recognition of this entity is of great importance to both pathologists and clinicians because atypical cellular neurofibroma is clever at masquerading both histologically and cytologically as a sarcoma therefore , a precise diagnosis of this variant is essential because of the differences in treatment and clinical behavior between benignancy and malignancy .

对於病理医师和临床医师来说，区分出这个纤维神经瘤的变异型非常重要，因为异生细胞纤维神经瘤在组织学上和细胞学上都非常类似肉瘤，因此正确的诊断出这个纤维神经瘤的变异型是必要的，因为临床上对於良性和恶性肿瘤的治疗和肿瘤行为表现是不同的。

The relationship of pulmonary artery to the lung lesion and degree of pulmonary arterial encasement could be used in differentiating benignancy from malignancy not only for central lung lesions but also peripheral lung lesions and this would decrease biopsy rate.

利用肺动脉及肺部病灶之间的关系以及利用肺动脉被包埋压迫的程度可以用来鉴别肺部病灶是良性病灶或是恶性肿瘤。

In this study, although the quantity of the scatter power can not reflect the content of blood flow, the scattered power variance is statistically significant between benignancy and malignancy （p=0.014 , sensitivity=80%, specificity 64%）. However, the PW Var does not have sufficient statistical significance in differentiate the normal tissue perfusion from the malignant one.

另外 Power Doppler的功率强度在整个实验的比较结果，虽然并不能证明与血流量、压力波有直接的关连，但是恶性肿瘤的功率强度的变异量均明显高於良性肿瘤（P=0.014 Sensitivity=80% Specificity 64%），不过恶性肿瘤却与正常组织无法区分。

objective to analyze the ct appearance of thyroid carcinoma and the differential diagnosis of various thyroid disease.methods 83 cases of thyroid carcinoma and 119 cases of various benign disease with surgical and pathologically proved were analyzed retrospectively.results the ct findings of 83 cases of thyroid carcinoma include:ill defined nodules boundary (n=62),irregular necrosis(n=59),cystic(n=23),"peninsula" enhancing tubercles around the tumour(n=25),"mastoid" tubercles around the tumour(n=11),calcification(n=55) including large scale(n=27) and local(n=28),trachea invasion(n=15),neck or supraclavicular lymph node metastasis(n=27),the accurate of ct to differentia benignancy from malignancy on thyroid disease was 93.6%(189/202).conclusions "peninsula" enhancing tubercles was the characteristic sing of thyroid carcinoma,"mastoid" enhancing tubercles or large scale calcification was the affirmative sign,the ct signs was vary useful to differentiating thyroid disease.

摘 要］目的：分析甲状腺癌的ct表现及鉴别诊断要点。方法：回顾性分析经手术病理证实的83例甲状腺癌和119例甲状腺良性病变的ct表现，归纳总结不同病变的ct特征。结果：83例甲状腺癌中：边界不清62例，不规则坏死59例，囊性变23例，出现"半岛状"强化结节25例，"乳头状"强化结节11例，钙化55例(其中弥漫性钙化27例、局灶钙化28例)，侵犯气管15例，颈部或锁骨上淋巴结肿大27例，ct对甲状腺病变的良恶性鉴别诊断符合率93.6%(189/202)。结论："半岛状"强化结节是甲状腺癌的特征性表现，"乳头状"强化结节及弥漫性钙化可做为甲状腺癌的肯定性征象，掌握各种甲状腺病变的ct表现特点，对病变的定性诊断及鉴别诊断具有重要意义。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.
