摘要
目的 探讨肾图曲线形态联合血流灌注曲线在判断肾动态显像是否成功中的价值.方法 肾动态显像重做173例,其中显像不成功81例,注射失败92例.显像不成功者:肾图曲线有b段平台样型35例,69个肾脏(A组);a段与b段不匹配型26例,52个肾脏(B组);其他类型20例.注射失败者:注射部位放射性计数残留为5%~15% 39例,78个肾脏(C组);注射部位残留16%~30% 26例,51个肾脏(D组);注射部位残留大于30% 27例.分别记录两次GFR值,并行配对t检验.结果 仅采用肾血流灌注曲线表现判断显像不成功阳性率为81.5% (66/81),而用肾图曲线形态联合肾血流灌注曲线表现来判断显像不成功阳性率为100% (81/81)(x2=16.5,P<0.01).A、B、c、D组两次GFR分别为(17.02±6.71)、(28.54±8.97) mL/min(t=3.76,P<0.01);(20.96 ±5.89)、(29.03±9.08) mL/min(t =2.18,P <0.05);(19.64±9.02)、(31.64±7.02)mL/min(t=3.61,P<0.01);(11.32 ±5.02)、(31.01±8.45)mL/min(t=5.58,P<0.01).A、B组重做前后GFR比值分别为(0.594±0.075)、(0.732±0.081)(t=3.47,P<0.01);C、D组重做前后GFR比值分别为(0.606±0.064)、(0.368±0.061)(t =4.81,P<0.01).A、B组中无论血流灌注曲线形态正常与否,它们的GFR均被同等低估(t=1.34,1.27,P均>0.05).结论 联合运用肾图曲线形态和肾血流灌注曲线能更好地判断显像是否成功.
Objective To assess renal imaging by the renogram curve and perfusion curve. Methods There were 173 patients who had renal dynamic imaging redone. Among them, 81 were unsuccessful cases. 92 cases were failed injection. Out of unsuccessful cases, renal curve appear platform in section b, a total of 69 kidneys in 35 cases (Group A) ; 26 cases of renal curve showed unmatched section a and section b,a total of 52 kidneys (Group B) ; 20 cases of other types. Out of failed injection cases, 39 cases of radioactive counting residual 5%-15% in the injection site,a total of 78 kidneys (Group C) ; 26 cases of radioactive counting residual 16%-30% in the injection site,a total of 51 kidneys (Group D). Radioactive counting residual 〉30% in the injection site had 27 cases. GFR values were analyzed by t test. Results Positive rate of assessing unsuccessful imaging only by perfusion curve is 81.5% (66/81),the positive rate by the renogram curve and perfusion curve is 100% (81/81)(X2 = 16.5,P 〈 0.01). Both GFR values of group A,B,C,D were (17.02 ±6.71), (28.54 ±8.97)mL/min(t =3.76,P 〈0.01) ; (20.96 ±5.89), (29.03 ±9.08) mL/min(t =2.18 ,P 〈0. 05) ; ( 19.64 ±9.02), (31.64 ±7.02) mL/min( t =3.61 ,P 〈0.01) ;(11.32 ±5.02) ,(31.01 ± 8.45)mL/min(t =5.58,P 〈0.01. GFR ratio of group A,B were 0.594 ±0.075 and 0.732 ±0.081(t =3.47,P 〈0.01) ;GFR ratio of group C,D were (0.606 ±0.064), (0.368 ±0.061) (t =4.81, P 〈0.01 ). No matter perfusion curve of group A,B were normal or not,GFR was equally underestimated(t = 1.34, 1.27 ,P 〉 0.05. Conclusion Renogram curve and perfusion curve provide more reliable value in assessment of success of renal imaging.
