Analysis of Safety Measure of Using Pressure Injector During Enhanced CT & MR Scanning

We analysed retrospectively the cases who occur contrast leakage from blood vessels for using pressure injector during enhanced CT and MR scan from January to November, 2001. Because there are relative great pressure, high speed with high pressure injector, so it is easy to result in contrast leakage from blood vessels when injecting. It is preventive through standard operation, chose right puncture position, the gauge of injector needle and so on.
