CT在支原體肺炎中的影像特點及應用價值探析

[摘要] 目的 探析CT在支原體肺炎中的影像特點及應用價值。方法 方便選擇該院2013年9月—2015年9月收治的62例患者進行研究，以年齡大小實行分組，31例成人支原體肺炎患者為此次研究的研究組，而31例未成年支原體肺炎患兒為對照組，兩組均接受CT掃描檢查，并對比組的CT檢查影像特點進行對比。對全部患者治療前和治療后2周、4周的影像學進行分析，并對比兩組的影像學特征。 結果 全部患者入院治療后2周，磨玻璃樣變和小斑片狀或結節狀實變影等影像學表現均消失，其中表現為大片狀實變影、縱隔淋巴結腫大和胸腔積液的僅有2例，均為6.45%，少于入院時的25.81%和77.42%，P<0.05，縱隔淋巴結腫大1例，占3.23%，少于入院時的12.90%；經過4周的時間治療后，各項影像學特征均消失。研究組的磨玻璃樣變、小斑片狀或結節狀實變影還有樹芽征這幾個影像學特征表現上的比重分別為77.78%、75.00%和80.00%，明顯多于對照組的22.22%、25.00%和20.00%，P<0.05；而支氣管血管束增粗、大片狀實變影、縱隔淋巴結腫大還有胸膜腔積液的比重為33.33%、12.50%、0.00%和29.17%，則小于對照組的66.67%、87.50%、100.00%和70.83%，P<0.05。 結論 將CT掃描檢查方法應用在支原體肺炎患者的臨床診斷上，能夠獲得較為明顯的影像學特點，進而提升患者的臨床診斷效率，值得推廣。

[Abstract] Objective To analyze the CT imaging characteristics and application in mycoplasma pneumonia. Methods Convenient selection our hospital from September 2013 to September 2015，62 patients admitted to the study， in order to implement age group， 31 patients with adult mycoplasma pneumoniae for this study groups， and children with 31 cases of mycoplasma pneumonia minors control group， underwent CT scan and CT scan imaging contrast group characteristics were compared. For two weeks， four weeks all patients before and after treatment and imaging st-udies were analyzed and compared the imaging features of the two groups. Results All patients admitted to hospital after 2 weeks of treatment， GGO and small patchy or nodular opacities and other imaging findings disappeared， which showed large patchy opacities compartment lymph nodes and pleural effusion only there are two cases were 6.45%， less than the time of admis-sion 25.81% and 77.42%， P <0.05， separated lymphadenopathy 1 cases， accounting for 3.23%， less than the time of admission 12.90%； after four weeks time after treatment， the imaging characteristics disappeared. Study Group GGO， the proportion of small patchy or nodular opacities tree buds also sign several imaging features on performance were 77.78%， 75.00% and 80.00%， significantly more than the control group of 22.22%， 25.00% and 20.00%， P <0.05； and th-ickening of the bronchial vascular bundle， large patchy opacities， swollen ly-mph nodes as well as every other pleural effusion accounted for 33.33%， 12.50%， 0.00% and 29.17%， 66.67% less than the control group， 87.50%， 100.00% and 70.83%， P <0.05. Conclusion The method of CT scan is used in the clinical diagnosis of patients with mycoplasma pneumonia， can obtain more obvious imaging characteristics， raise the efficiency of clinical diagnosis of the patients， is worth promoting.

支原體肺炎是由支原體引起的以間質改變為主的肺炎，好發于小兒，這種微生物由口、鼻的分泌物經空氣傳播，引起散發性的、甚或流行性呼吸道感染，多發生于冬春及夏秋之交，且病程較長，一般在5年時間左右，若病原體得不到有效控制，則會通過呼吸道傳染至機體內部臟器，具體臨床癥狀表現為咳嗽、低熱、咳少量白色粘液痰等，但是肺部表現無明顯特征性[1-3]?！?br>
