胰腺炎脾血管并發(fā)癥是較為常見的胰腺炎血管并發(fā)癥，其發(fā)生率雖不高，卻是胰腺炎病情重危程度、預后不良的征象之一，如脾動脈假性動脈瘤破裂可危及患者的生命。因此對于胰腺炎脾血管并發(fā)癥的準確診斷就顯得特別重要。超聲作為急性胰腺炎檢查中最常用的手段，由于易受胃腸道麻痹致腹內(nèi)脹氣、腹膜后血管彩色血流衰減、檢查者經(jīng)驗和手法等原因的影響，導致超聲對于胰腺炎脾血管并發(fā)癥的診斷準確率較低?，F(xiàn)通過文獻復習，對該病的發(fā)生、發(fā)展以及診斷的進展進行綜述，以提高超聲醫(yī)師對該疾病的認識，提高診斷的準確性。
【摘要】 目的 探討彈性成像在甲狀腺微小癌診斷中的應用價值。 方法 回顧性分析從2007年12月-2008年4月間經(jīng)病理證實的10例甲狀腺微小癌患者共11個病灶的超聲表現(xiàn)。 結(jié)果 彩色多普勒超聲診斷甲狀腺微小癌8例8個病灶，利用彈性成像技術(shù)診斷10例10灶。傳統(tǒng)彩色多普勒超聲對甲狀腺微小癌的診斷率為72.7%；利用彈性成像技術(shù)對甲狀腺微小癌的診斷率為90.9%。 結(jié)論 彈性成像技術(shù)對于甲狀腺微小癌是對彩色多普勒超聲檢查的有益的補充，能夠顯著提高超聲對甲狀腺微小癌診斷的準確性。【Abstract】 Objective To evaluate the application of US-elastography in diagnosis of thyroid microcacinoma. Methods The images of color ultrasound and ultrasound elastography from 11 lesions of 10 patients with thyroid micro-carcinoma diagnosed via histopathology between December 2007 and April 2008 were retrospectively analyzed. Results Eight patients with eight lesions were found by colour ultrasound and 10 patients with 10 lesions were observed by ultrasound elastography. The diagnosis accurate rate of ultrasonography was about 72.7% and of ultrasound elastography was about 90.0%. Conclusion US-Elastography is a beneficial addition in diagnosis of thyroid microcacinoma by colour ultrasound. It can remarkably develop the accurate rate of the diagnosis of the disease.
【摘要】 目的 分析超聲對腺性膀胱炎的誤、漏診原因，探討減少其誤、漏診的方法?！》椒ā』仡櫺苑治?006年1月-2010年2月經(jīng)病理證實的135例腺性膀胱炎的聲像圖表現(xiàn)?！〗Y(jié)果 135例腺性膀胱炎患者中，超聲誤診26例，誤診率19.3%，漏診11例，漏診率8.2%。誤診的主要原因：乳頭結(jié)節(jié)型和團塊型與膀胱腫瘤聲像圖極為相似、容易混淆，超聲醫(yī)師對膀胱壁各層次的觀察不仔細，對病史重視不夠；漏診的主要原因：膀胱充盈不佳或不充盈，病變體積太小、位于前壁或頂部，或病變位于膀胱后壁及頸部被明顯增生的前列腺、膀胱內(nèi)血凝塊及膀胱結(jié)石等掩蓋。 結(jié)論 超聲是診斷腺性膀胱炎常用方法，但存在一定的誤、漏診，改進檢查方法，可減少其誤、漏診發(fā)生。【Abstract】 Objective To analyze the reasons of missed diagnosis and misdiagnosis of glandularis cystitis by ultrasonography. Methods The sonographic outcomes of 135 patients with glandular cystitis diagnosed by pathological examination from January 2006 to February 2010 were retrospectively analyzed. Results In 135 patients, misdiagnosis was in 26 with a rate of 19.3%, missed diagnosis was in 11 with a rate of 8.2%. The reasons of misdiagnosis included: the sonographic outcomes of mastoid and tuberculous conglomeration were similar to those of bladder tumour; the ultrasonographic professionals didn’t clearly observe each layer of the bladder wall, and didn’t pay enough attention to the disease history. The reasons of missed diagnosis included: the bladder was under-filled or unfilled, the size of the lesions were too small and were located at the anterior wall or the top, and the lesions were located at the posterior wall and neck of the bladder which were covered up by obvious prostate hyperplasia,and gores or stones of bladder so that the lesions could not be observed. Conclusion Ultrasonography is a usual method for diagnosing glandular cystitis,and we should ameliorate the examination to decrease the misdiagnosis and missed diagnosis.
目的 探討甲狀腺髓樣癌的超聲聲像圖特點，以提高超聲診斷水平。 方法 回顧性分析2006年1月－ 2010年9月經(jīng)手術(shù)切除及病理組織學證實的16例甲狀腺髓樣癌20個結(jié)節(jié)的超聲聲像圖表現(xiàn)。 結(jié)果 20個甲狀腺髓樣癌結(jié)節(jié)中，結(jié)節(jié)呈低回聲20個，結(jié)節(jié)內(nèi)部有鈣化灶者13個，結(jié)節(jié)內(nèi)血流豐富者13個，合并有甲狀腺乳頭狀微小癌1例，頸部淋巴結(jié)腫大17例。 結(jié)論 甲狀腺髓樣癌具有一定的超聲聲像圖特點，了解這些特點可以提高超聲對甲狀腺髓樣癌的診斷水平。
