Abstract:
Objective To research paramagnetic contrast media(PCM)dose,injection speed and imaging time etc in low field MRI.Methods 406 patients with lesions spreading all over the body received Gadolinium-DTPA-enhanced scan by bolus injection with the dose of 0.1～0.15 mmol/kg within 60 seconds,and the effects of contrast-enhanced were observed.Results Among 406 patients lesions,337 cases(83%)were enhanced,9 undiscovered lesions displayed enhancement on the precontrast views,5 cases were discovered new lesions in delaying enhancement scan.Conclusion It is safe to apply the above mentioned dose and injection speed in clinic.The side-effects is small,and the development effect is good.It is especially important for lesions involving the structure of the blood brain barrier(BBB).
