摘要
高分辨率 CT(HRCT)目前是一种使空间和密度分辨率尽可能完善的 CT技术 ,是当今评价肺内小结节性病灶和细支气管疾病最理想的影像方法。由于该 CT技术的应用使人们对影像解剖学也有了更深入细致的认识 ,达到了“微观影像”的程度 ,越来越显示其独特的优点。本文就近年来小气道的 HRCT解剖、HRCT技术以及在小气道疾病状态下的病理变化与相应的 HRCT表现作一综述 ,重点阐述 HRCT在其诊断中的应用价值。
HRCT(high resolution computed tomography) at present has been the perfect technique of CT in the spatial and contrast resodution and the best imaging method of assessments of small sati solitary nodular lesions and bronchiolar diseases in the lungs.Because of the use of the method,HRCT in the anatomys has been understood in the depth and detail,and comes up to the levels of “microimages” and more and more shows its advantage.The author reviews the HRCT anatomys,techiques and pathologys of the small airways in the recent years,and elaborates the important value of HRCT in the diagnosis.
