双源64排螺旋CT对肝脏血管瘤强化容积测定的临床应用

Study on clinical application of hepatic hemangioma groups and types by dual-source 64-slice spiral CT

目的评价双源64排螺旋CT对肝脏血管瘤动态增强扫描后的强化容积测定及其临床应用价值。方法应用SIEMENS双源64排螺旋CT对125例肝血管瘤患者进行三期动态增强扫描后,并应用容积测定软件测定不同时相的强化容积,将数据进行统计分组、分型(乏血供、富血供两种类型)。结果直径(d)小于4.00cm的肝血管瘤动脉期强化容积比率均大于28.00%,平均为(53.68±13.25)%;4.0cm<d≤10.0cm的肝血管瘤动脉期强化容积比率为(22.25±3.25)%;d>10.0cm的肝血管瘤动脉期强化容积比率均小于18.50%,平均为(13.28±4.26)%。结论对于4.0cm<d≤10.0cm的肝血管瘤,动脉期强化比率大于22.25%的病灶,可认为其动脉期血供丰富(富血供型);小于22.25%的病灶,可认为其缺乏动脉供血(乏血供型);直径小于4.00cm的肝血管瘤多为富血供型,d>10.0cm的肝血管瘤多为乏血供型。双源64排螺旋CT三期动态增强扫描可了解肝脏血管瘤的血供情况,从而为肝脏血管瘤的动脉栓塞治疗提供依据。

Objective To study clinical application of hepatic hemangioma groups and types by using dual-source 64-slice spiral CT.Methods Application of dual-source 64-slice spiral SIEMENS CT in 125 cases of hepatic hemangioma in patients with three dynamic enhanced scan,and apply the determination of volume measurement software enhanced at different phases of the volume of statistical data grouping,sub-type（lack of blood supply and rich blood supply）.Results The diameter was less than 4.00 cm of hepatic hemangioma in the arterial phase enhancement ratios are more than 28.00% with an average of 53.68 ± 13.25%;4.0cm d ≤ 10.0 cm hepatic arterial vascular tumor volume ratio of the enhanced 22.25%± 3.25%;d 10.0 cm hepatic arterial vascular tumor volume ratio of enhancement was less than 18.50%,an average of 13.28% ± 4.26%.Conclusion For hepatic hemangioma of 4.0cm〈 d ≤ 10.0cm,arterial phase enhancement ratio of greater than 22.25% of the lesions,it can be considered arterial blood supply（the rich blood supply type）;less than 22.25% of the lesions,can be considered its lack of arterial blood supply（lack of blood supply type）;Diameter of less than 4.00cm of hepatic hemangiomas are mostly rich blood supply type;d 10.0cm hepatic hemangiomas mostly for lack of blood type.
