目的:分析小細(xì)胞肺癌(small cell lung cancer,SCLC)的CT表現(xiàn)特點(diǎn),以提高對(duì)該病的認(rèn)識(shí)。方法:收集有CT和臨床資料并經(jīng)病理證實(shí)的SCLC 60例,回顧性總結(jié)分析CT影像特征。結(jié)果:中央型肺癌47例,CT表現(xiàn)為肺門分葉狀結(jié)節(jié)或腫塊,伴阻塞性肺炎11例(23.4%),阻塞性肺不張5例(10.6%),42例(89.4%)伴有縱隔淋巴結(jié)腫大,36例行CT增強(qiáng),其中32例腫塊和淋巴結(jié)均勻強(qiáng)化。13周圍型SCLC中,9例腫大的肺門、縱隔淋巴結(jié)較肺內(nèi)腫瘤大。結(jié)論:SCLC CT主要征象以肺門區(qū)實(shí)性腫塊為主,多伴有肺門、縱隔淋巴結(jié)轉(zhuǎn)移,支氣管阻塞征象出現(xiàn)較晚。
目的:探討鼻咽纖維血管瘤術(shù)前栓塞的應(yīng)用價(jià)值。方法:17例鼻咽纖維血管瘤患者,單純手術(shù)摘除10例,術(shù)前3天進(jìn)行數(shù)字減影血管造影(DSA)檢查及血管內(nèi)栓塞術(shù)7例。結(jié)果:7例術(shù)前栓塞組術(shù)中出血200～700mL,平均430mL;輸血0～550mL;10例單純手術(shù)組出血550～1430mL,平均1200mL,輸血350～1200mL。術(shù)前栓塞組出血量和輸血量較單純手術(shù)組顯著減少。結(jié)論:術(shù)前瘤體栓塞治療鼻咽纖維血管瘤是安全有效、理想的術(shù)前輔助治療手段。
胰腺導(dǎo)管內(nèi)乳頭狀黏液性腫瘤是一種臨床上少見的發(fā)生于胰腺導(dǎo)管上皮細(xì)胞腫瘤，近年來對(duì)該病的報(bào)道逐漸增多，現(xiàn)著重介紹其臨床病理學(xué)、常用影像學(xué)表現(xiàn)及方法比較、影像學(xué)提示腫瘤惡性的因素及鑒別診斷，旨在提高對(duì)其影像學(xué)認(rèn)識(shí)。
【摘要】 宮頸癌的發(fā)病率居國內(nèi)女性生殖系統(tǒng)惡性腫瘤的首位。臨床檢查以婦科檢查為主，有一定的主觀性和局限性。陰道鏡下行宮頸組織活檢病理學(xué)檢查，對(duì)宮頸癌前病變較為實(shí)用，準(zhǔn)確率較高。因此，宮頸組織活檢病理學(xué)檢查是確診宮頸癌的金標(biāo)準(zhǔn)。B型超聲、CT及MRI影像檢查在宮頸癌的診斷、分期及治療計(jì)劃制定和療效評(píng)價(jià)中起著越來越重要的作用?，F(xiàn)就各種影像學(xué)檢查在宮頸癌中的診斷及分期予以綜述。
【摘要】 目的 探討系統(tǒng)性紅斑狼瘡腦病（SLEE）的磁共振成像（MRI）特征和診斷價(jià)值。 方法 回顧性分析2007年1月-2009年7月間18例SLEE的臨床表現(xiàn)及MRI特征。 結(jié)果 18例患者M(jìn)RI檢查的顱腦陽性率為88.88%（16/18），腦部MRI表現(xiàn)為:①15例為多發(fā)病灶，局灶者1例。②雙側(cè)大腦半球、基底節(jié)區(qū)及小腦半球腦實(shí)質(zhì)內(nèi)長T1、長或稍長T信號(hào)，DWI及EPI成像上呈高或稍高信號(hào)，灰白質(zhì)均可受累，分布無規(guī)律性。③增強(qiáng)MRI掃描9例，其中5例呈斑片狀強(qiáng)化，4例無明顯強(qiáng)化。④腦梗死12例，腦出血4例。合并腦水腫9例，腦萎縮7例。 結(jié)論 SLEE的MRI表現(xiàn)多樣，結(jié)合臨床資料，MRI可以作出診斷。【Abstract】 Objective To investigate the magnetic resonance imaging (MRI) features of systemic lupus erythematosus encephalopathy (SLEE) and its diagnostic value. Methods The clinical data and MRI images of 18 patients with SLEE admitted from January 2007 to July 2009 in our hospital were analyzed retrospectively. Results Positive findings were found in 16 patients (88.88%). MRI findings of SLEE were the following: ①A Total of 15 patients were with diffuse lesions, one patient was with focal lesions. ②Cerebral hemisphere involvement and bilateral caudate long T1 and long or slightly long T2 signal were intensive in the brain parenchyma, and appeared as hyper-intensity or slightly hyper-intensity on DWI and EPI. Grey and white matters were involved often and irregularly distributed. ③The results of 9 patients by enhanced MRI showed that 5 patients were with patchy enhancement and 4 were without enhancement. ④Of the 16 positive patients, 12 were with cerebral infarction and 4 with cerebral hemorrhage, while 9 patients were complicated with cerebral edema, and 7 patients were with cerebral atrophy. Conclusion MRI manifestations of SLEE are various. Combined with clinical data, MRI can diagnose SLEE exactly.
目的:探討單發(fā)腦轉(zhuǎn)移瘤的CT和MRI診斷價(jià)值。方法:回顧性分析37例經(jīng)手術(shù)病理證實(shí)或臨床綜合診斷確診的單發(fā)腦轉(zhuǎn)移瘤的CT和MRI表現(xiàn)。結(jié)果:病灶位于幕上31例,分布于皮髓質(zhì)交界區(qū)21例。囊實(shí)性22例,實(shí)性9例,囊性6例。不規(guī)則環(huán)形強(qiáng)化13例,結(jié)節(jié)形強(qiáng)化7例,囊實(shí)形強(qiáng)化15例,均勻強(qiáng)化2例。病灶直徑gt;1.0 cm時(shí)瘤周水腫常較明顯。結(jié)論:單發(fā)腦轉(zhuǎn)移瘤的CT、MRI表現(xiàn)具有一定的特征,增強(qiáng)掃描對(duì)診斷單發(fā)腦轉(zhuǎn)移瘤有重要價(jià)值。
