目的:讨论不同造影剂注射速率对64排螺旋 CT 扫描肝脏动脉期增强效果的影响。方法选取2014年1月至2015年4月行腹部 CT 扫描的患者60例,以病情的不同为分组依据,将其分为对照组(30例)及肝硬化组(30例)。再将各组以注射速率为分组依据分为2.5 mL/s 组(对照组1、肝硬化组1)及3.5 mL/s 组(对照组2、肝硬化组2)。选择 Smartprep 技术对所有患者进行造影剂跟踪,当腹主动脉 CT 值≥150 HU 时开始扫描。将各组腹主动脉动脉期出发时间、CT 值进行记录,同时分析各组成像质量。结果当造影剂注射速率为3.5 mL/s 时,对照组优良率(95.5%)与造影剂注射速率为2.5 mL/s 时(91.7%)差异无统计学意义(χ2=0.021,P =0.638);肝硬化组优良率(94.7%)较造影剂注射速率为2.5 mL/s 时(72.7%)优势明显,差异有统计学意义(χ2=5.233,P =0.032)。当造影剂注射速率为2.5 mL/s 时,肝硬化组腹主动脉平均强化峰值[(187.25±21.00)HU]与对照组[(195.35±19.00)HU]差异无统计学意义(t =0.826,P =0.436);对照组平均触发时间[(21.68±1.93)s]明显短于肝硬化组[(25.13±2.13)s],差异有统计学意义(t =2.064,P =0.047)。当造影剂注射速率为3.5 mL/s 时,对照组腹主动脉平均强化峰值[(247.82±39.00)HU]明显大于肝硬化组[(223.81±35.00)HU],差异有统计学意义(t =2.652,P =0.037);对照组平均触发时间[(18.62±1.36)s]明显短于肝硬化组[(24.57±0.92)s],差异有统计学意义(t =3.362,P =0.033)。结论造影剂注射速率越大,动脉期峰值就随之增大,同时达峰时间随之缩短。当造影剂注射速率一致时,对照组平均触发时间短、平均强化峰值高。肝硬化患者需更高的造影剂注射速率。
目的:討論不同造影劑註射速率對64排螺鏇 CT 掃描肝髒動脈期增彊效果的影響。方法選取2014年1月至2015年4月行腹部 CT 掃描的患者60例,以病情的不同為分組依據,將其分為對照組(30例)及肝硬化組(30例)。再將各組以註射速率為分組依據分為2.5 mL/s 組(對照組1、肝硬化組1)及3.5 mL/s 組(對照組2、肝硬化組2)。選擇 Smartprep 技術對所有患者進行造影劑跟蹤,噹腹主動脈 CT 值≥150 HU 時開始掃描。將各組腹主動脈動脈期齣髮時間、CT 值進行記錄,同時分析各組成像質量。結果噹造影劑註射速率為3.5 mL/s 時,對照組優良率(95.5%)與造影劑註射速率為2.5 mL/s 時(91.7%)差異無統計學意義(χ2=0.021,P =0.638);肝硬化組優良率(94.7%)較造影劑註射速率為2.5 mL/s 時(72.7%)優勢明顯,差異有統計學意義(χ2=5.233,P =0.032)。噹造影劑註射速率為2.5 mL/s 時,肝硬化組腹主動脈平均彊化峰值[(187.25±21.00)HU]與對照組[(195.35±19.00)HU]差異無統計學意義(t =0.826,P =0.436);對照組平均觸髮時間[(21.68±1.93)s]明顯短于肝硬化組[(25.13±2.13)s],差異有統計學意義(t =2.064,P =0.047)。噹造影劑註射速率為3.5 mL/s 時,對照組腹主動脈平均彊化峰值[(247.82±39.00)HU]明顯大于肝硬化組[(223.81±35.00)HU],差異有統計學意義(t =2.652,P =0.037);對照組平均觸髮時間[(18.62±1.36)s]明顯短于肝硬化組[(24.57±0.92)s],差異有統計學意義(t =3.362,P =0.033)。結論造影劑註射速率越大,動脈期峰值就隨之增大,同時達峰時間隨之縮短。噹造影劑註射速率一緻時,對照組平均觸髮時間短、平均彊化峰值高。肝硬化患者需更高的造影劑註射速率。

Objective To discuss the different contrast injection rate on the 64 -slice spiral CT scan liver arterial phase reinforced effect.Methods 60 patients who received abdominal CT scan were selected from January 2014 to April 2015.According to the different conditions,they were divided into control group (30 cases)and liver cirrhosis group (30 cases).Then each group based on packet injection rate into 2.5 mL/s (control group 1,cirrhosis group 1)and 3.5 mL/s (control group 2,cirrhosis group 2).Select Smartprep technology contrast agent tracking all patients,when the abdominal aorta CT value ≥150 HU start scanning.The departure time,CT value of each group were recorded,abdominal aortic artery,simultaneous analysis of each component of image quality comparison.Results When the contrast agent injection rate of 3.5 mL/s,excellent rate of the control group (95.5%)compared with the contrast injection rate of 2.5 mL/s (91.7%)had no significant difference (χ2 =0.021,P =0.638);The cirrhosis good rate (94.7%)compared with the contrast agent injection rate of 2.5ml/s (72.7%)had obvious advantages, the difference was statistically significant (χ2 =5.233,P =0.032).When the contrast agent injection rate of 2.5mL/s, cirrhosis abdominal aorta average peak enhancement [(187.25 ±21.00)HU]and the control group [(195.35 ± 19.00)HU]had no significant difference (t =0.826,P =0.436).The average trigger time of the control group (21.68 ±1.93)s was significantly less than the cirrhosis group (25.13 ±2.13)s,the difference was statistically significant (t =2.064,P =0.047).When the contrast agent injection rate of 3.5 mL/s,the control group,the mean abdominal aortic peak enhancement [(247.82 ±39.00)HU]was significantly greater than the cirrhosis group [(223.81 ±35.00)HU],the difference was statistically significant (t =2.652,P =0.037).The average trigger time of the control group (18.62 ±1.36)s was significantly less than the cirrhosis group (24.57 ±0.92)s,the difference was statistically significant (t =3.362,P =0.033).Conclusion The greater the contrast injection rate,arterial peak at the same time it increases the peak time come to shorten.When the contrast agent injection rate consistent with the control group,the average trigger time is short,high average peak enhancement.Cirrhosis needs higher contrast injec-tion rate.
