高KV和普通KV摄影在静脉肾盂造影检查中吸收剂量的临床研究

目的 探讨高KV和普通KV摄影在静脉肾盂造影（IVP）检查过程中,患者受到X线辐射的剂量。方法 本文共监测了60例IVP患者,分为观察组和对照组,60例患者均使用LiF（氟化锂）个人剂量测量牌分别置3个部位进行检测。观察组患者分别于注射造影剂前和注射造影剂后15min、45min进行高KV摄影;对照组患者于注射造影剂前和注射造影剂后15min、45min进行普通KV摄影。结果 下肢和生殖器两个部位,观察组患者吸收剂量明显低于对照组,差异有显著性意义（P〈0.05）。结论 高KV摄影辐射剂量明显低于普通KV摄影,在实际工作中应该选择高KV摄影。

The Clinic Research about Dosage in IVP Examination of High KV Film and Common KV Film

Objective To investigate the exposed X - ray radiation dosage for patients in the IVP examination with high KV and common KV. Methods The exposed dosages of 60 cases with IVP were analyzed, which were divided into observed group and control group. The dosages were taken using LiF from 3 different monitor points for each patient. Patients in observe group were exposed under high KV before and after contrast medium injection at 15 mins and 45 mins. Patients in contrast group were exposed under common KV before and after contrast medium injection at 15 mins and 45 mins. Results The exposed dosages at leg and genitalia for patients in observed group were much lower than that in control group. The difference was significant. Conclusion The exposed dosages under high KV was much lower than that under common KV, so the specialty of IVP examination and High KV film should be chosen in practice.
