摘　　要：目的评价多排螺旋CT(MSCT)低剂量模式扫描在新生儿肾上腺出血(NAH)中的应用价值。方法收集2009年5月至2013年3月在广东省妇幼保健院确诊的32例NAH患儿的临床病历资料为研究对象。其中,急性期为3例,亚急性期为20例,慢性期为6例,血肿机化期为3例。采用SIEMENZ128排及TOSHIBA 64排MSCT低剂量模式(80kV,100mA,0.75s),评价MSCT低剂量模式对NAH的应用价值(本研究遵循的程序符合广东省妇幼保健院人体试验委员会制定的伦理学标准,得到该委员会批准,并征得受试对象监护人的知情同意)。结果 NAH的普通CT检查表现为肾上腺区低密度或混杂密度肿块,右侧多见,有包壳或囊壁形成,增强CT结果示病灶中央区无强化。结论 MSCT低剂量模式成像清晰,对NAH的定性和分期具有很好参考价值。Objective To investigate the application of low dose multi-sliced CT（MSCT） scanning on neonatal adrenal hemorrhage （NAH）. Methods A total of 32 cases diagnosed as NAH in Guangdong Maternal and Children Hospital were recruited from May 2009 to March 2013, including 3 cases of acute stage, 20 of subacute stage, 6 of chronic stage and 3 of organizing stage. SIEMENZ 128-sliced and TOSHIBA 64-sliced CT scanning were conducted on all the patients in low dose mode. The application value of MSCT on NAH was explored. This programme was approved by Guangdong Maternal and Children Hospital＇s human research committee, coincident the ethical standards, and consents were obtained by the guardians. Results MSCT image signs of NAH included low or mixed density mass in adrenal area, usually in right side, with thin involucrum or cyst wall, and no enhance in central site. Conclusions MSCT low- dose scanning provides clear images and is of valuable to diagnose and stage NAH.
