摘  要:目的探讨基于Couinaud分段多层螺旋CT(MSCT)全肝灌注成像对慢性乙型肝炎肝硬化患者血流状况的评估价值。方法选取2013年1月至2014年1月在山东省滨州市中心医院进行治疗的50例慢性乙型肝炎肝硬化患者为观察组,另选取50名同期来本院进行体检的正常肝脏者为对照组。对所有对象行基于Couinaud分段MSCT全肝灌注成像,测量各段灌注参数,将肝硬化按肝功能Child—pugh分级标准分为A级(23例)、B级(20例)、C级(7例),与正常组肝脏五叶血流灌注参数进行比较。结果观察组灌注峰值时间较对照组长[主动脉:(15±4)S比(14±3)S,门静脉:(36±8)s比(29±5)s,脾脏:(27±6)s比(23±5)S]、强化峰值较对照组低[主动脉:(266±54)HU比(272±53)HU,门静脉:(81±31)HU比(91±34)HU,脾脏:(35±15)HU比(51±23)HU],差异有统计学意义(P〈0.05)。观察组Couinaud各段灌注量参数值各不相同,且各段肝动脉灌注量、门静脉灌注量、全肝总灌注量及肝动脉灌注指数参数差异均有统计学意义(均P〈0.05);其中肝脏SⅢ段与SⅦ段每灌注100ml的肝动脉灌注量值分别为(11±5)ml/min、(10±5)ml/min,二者差异有统计学意义(P〈0.05)。肝脏各叶门静脉灌注量与全肝总灌注量在观察组A级、B级、C级患者均低于对照组,差异均有统计学意义[门静脉灌注量:尾状叶(58.3±31.2)、(68.7±21.0)、(58.9±30.7)ml/min比(92.7±44.7)ml/min,左外叶(57.6±21.0)、(68.3±20.8)、(58.5±23.8)ml/min比(87.0±34.4)ml/min,左内叶(63.5±23.2)、(73.2±22.1)、(62.1±31.8)ml/min比(84.2±27.3)ml/min,右前叶(69.5±28.5)、(70.7±28.4)、(70.5±27.5)比(91.8±24.1)ml/min,右后叶(56.5±16.8)、(68.1±25.8)、(57.9±15�Objective To explore the value of whole liver perfusion imaging by multi-slice spiral computed tomography (MSCT) based on Couinaud segments to evaluate the blood flow state in patients with chronic hepatitis B cirrhosis. Methods Totally 50 patients with chronic hepatitis B cirrhosis from January 2013 to January 2014 were selected as observation group, according to Child-pugh grading, the patients were divided into grade A ( 23 cases) , grade B ( 20 cases) and grade C (7 cases) ; in addition, 50 healthy volunteers with normal liver were set as control group. The MCST whole liver perfusion imaging based on Couinaud segments was performed, the perfusion parameters were measured and compared among groups. Results The peak time in observation group was significantly longer than that in control group[aorta: (15 ±4) s vs (14 ±3) s, portal vein: (36 ±8) s vs (29 ± 5) s, spleen: (27 ±6) s vs (23±5 ) s ] ; the peak enhancement in observation group was significantly lower than that in control group group[ (266 ±54) HU vs (272 ±53) HU, portal vein: (81 ±31 ) HU vs (91 ± 34) HU, spleen: (35 ±15) HU vs (51 ±23) HU] (P 〈0. 05). In observation group, the perfusion parameter of each Couinaudg segment was not the same and the portal venous perfusion, total hepatic perfusion and hepatic perfusion index were significantly different (P 〈 0.05 ) ; at S Ⅲand SⅦI segment, the hepatic arterial peffusion per 100 ml was significantly different [ ( 11 ±5) ml/min vs ( 10 ±5) ml/minl (P 〈0. 05). The hepatic portal vein perfusion and whole liver perfusion were significantly lower in cirrhosis patients with Chfld-Pugh grade of A, B, C than those in control group [ portal vein perfusion: caudate lobe (58.3 ± 31.2), (68.7 ± 21.0), (58.9 ±30. 7) ml/min vs (92. 7 ±44. 7) ml/min; left lateral (57, 6 ±21, 0), (68. 3 ±20. 8), (58. 5 ±23.8)ml/min vs (87.0±34.4) M/rain; left lobe (63.5 ±23.2�
