40例脑卒中临床和CT扫描不符结果的分析

近3年来,对318例各型脑卒中,CT扫描阳性率达91.1％,其中脑出血全部阳性,脑梗塞86.4％阳性。为进一步提高诊断质量和合理使用CT扫描技术,对其中40例住院患者,临床和CT扫描的不符结果,进行了分析讨论。     

CT扫描对脑血管病的诊断评价(附90例临床分析)

CT扫描自1972年Hounfield首创,1973年问世以来,由于其使用简便,曝光量少,显影清晰,对病人无痛苦,诊断迅速,定位精确;国外已广泛应用于临床,国内尚仅有少数医院开始应用。现将我院近两年来,90例脑血管病的CT扫描结果进行分析,并就CT扫描对脑血管病的诊断进行评价。     

空气支气管征在周围型小肺癌CT鉴别诊断中的价值

空气支气管征于常规X线上常被视为肺叶、肺段实变的征象。有关此征象在周围肺肿块的CT-病理研究报道极少。本文通过50例周围肺小结节的CT一病理对照来探讨此征象CT鉴别良、恶性肺结节的价值。本文收集了近4年经手术病理证实的直径≤3cm的周围肺小结节50例:周围型小肺癌37例,其中鳞癌11例、腺癌20例,大细胞癌2例、腺鳞癌4例;肺良性小结节13例,其中错构瘤1例、肺囊肿1例、炎性假瘤3例、结核瘤8例。肺标本用Heitzman法充气固定20例。CT为荷兰飞利蒲Tomoscan350扫描     

CT在诊断肺癌上的应用

自从CT应用于临床以来,在诊断颅脑和腹部脏器(肝、胰、肾、腹膜后等)疾患的报道较多,而有关胸部特别是肺疾患的CT诊断文献为数则不多,甚至有的作者认为CT诊断肺内病变还不如普通x线照片或断层     

HISTOPATHOLOGIC CORRELATION OF CT FINDINGS IN CE.REBRAL HEMORRHAGE AND INFARCT

Twenty-seven brains of patients with cerebrovas cular disease were examined by computed tomography (CT) and studied correlatively with neuropathological findings. CT was done shortly before death in three cases. Twelve hemorrhages in the cerebral hemi- sphere and four of seven hemorrhages in the brain stem were detected by CT respectively. The three hemorrhages in the brain stem, not revealed by CT, were less than 0.2 cm in diameter. Seven of the 12 hemorrhages in the hemisphere showed hypodense zones on CT, and were proved microscopically to be necrosis instead of edema. The other 5 failed to show hypodensity on CT. Of these, 3 were due to small hemorrhage without necrosis, and 2 were he- morrhage with surrounding necrosis in repair with glial scar and gitter cells containing iron granules. Of 37 cerebral infarcts, only 19 were revealed by CT, a positive rate of 51'70, and 18 missed by CT as they were small in size, special in shape and different in constituents. The significance of the presence of atrophy of the pes pedunculus on one side on CT is discussed in detail.     

后颅凹肿瘤的CT诊断

后颅凹肿瘤约占儿童颅内肿瘤的1/2,占成人颅内肿瘤的1/4。CT 对脑肿瘤的准确检出率为97%,组织学推断确率为80%。下面依解剖结构将后颅凹肿瘤分三组叙述。并将鉴别诊断列表于后。小脑及第四脑室肿瘤一、髓母细胞瘤占儿童小脑及第四脑室肿瘤的第一位,好发于后颅凹中线部位,如小脑蚓部(约占3/4～4/5),亦可见于小脑半球。肿瘤呈圆形或椭圆形,如位于小脑半球可有分叶表现。平扫时为均匀高密度     

肺癌CT诊断的初步探讨

鉴于目前对于CT扫描诊断肺部疾患的价值各家意见尚不一致,有人认为CT不如普通X线检查效果显著,但也有些作者认为CT扫描所得出的图象为横断面,有利于显示普通X线照片不易发现的病变,对于肺部疾患,特别是肺癌的诊断、确定病变范     

节段性结肠炎(附四例报告)

节段性结肠炎是一种原因不明的非特异性炎症性病变,病变侵犯结肠的一段或数段,病初直肠不受累。 1930年Bargen和Weber以局限性游走性慢性溃疡性结肠炎为名报告23例,引起了注意。见后,文献报道逐渐增多,但各家采用病名     

ANALYSIS OF X-RAY FINDINGS OF 22 CASES OF ACUTE PULMONARY MYCOSIS

The clinical and roentgenologic data of 22 cases of acute pulmonary mycosis are analyzcd, with special emphasis on the X-ray manifesta- tions.Of the 22 cases, 12 were roentgenographical- ly shown the so called "cottonball" nodular opacities in the chest, 4 cavitation and 6 pneu- monia-like prcsentatiom Furthermore, in 3 cases there were many small, snow-flake-like patchy opacities of heter09eneous density over 60% of both lung fields. The lesions, both unilateral and bilateral, were more concentrated in the middle and lower hu:tg fields* These lesions when enlarged with aggravation of the disease would join to form large patches within a few days or even hours.
