| 目的 探讨团注追踪法在下肢动脉造影中的应用价值。方法 随机选取在我院接受下肢动脉造影的患者30例,其中采用团注追踪法18例,常规造影法12例,对比二者的总辐射剂量、造影图像数、对比剂用量及造影时间的差异。结果 采用团注追踪法患者接受的总辐射剂量、造影图像数、对比剂用量、造影时间分别是(21.40±2.80)Gy/cm2、(30±41)幅、(26.56±6.84)ml、(3.03±1.29)min;而采用常规造影法患者分别为(55.00±4.30)Gy/cm2、(208±37)幅、(54.20±10.36)ml、(9.68±4.25)min,差异均有统计学意义(P＜0.01)。团注追踪法图像运动伪影偏多,但并不影响诊断。结论 在下肢动脉造影中,与常规造影法比较,团注追踪造影法对比剂用量较少、造影时间较短、患者接受的辐射剂量较少,具有一定临床应用价值。 |

| Objective To investigate the application value of bolus chase method in lower extremity angiography. Methods Thirty patients underwent lower extremity angiography, 18 using the bolus chase method, the other 12 using the routine method. Total dose radiation, the amount of acquired images, the amount of used contrast medium and the operation time were compared between two methods. Results The total dose radiation, acquired images, amount of used contrast medium and operation time of the bolus chase method was (21.40±2.80)Gy/cm2, 30±41, (26.56±6.84)ml, (3.03±1.29)min respectively, while of the routine method was (55.00±4.30)Gy/cm2, 208±37, (54.2±10.36)ml, (9.68±4.25)min,respectively. The differences were statistically significant (all P＜0.01). Images produced by bolus chase method had more motion artifacts, but did not influence diagnosis. Conclusion Compared with routine method, the bolus chase method needs less contrast medium, less operation time and less radiation dose in lower extremity angiography, therefore has important clinical value. |
