The aim of the study is to determine the best proportion of splitting the iodine contrast medium to achieve the best possible parenchymal and excretory phase pattern in paediatric politrauma patients at Children University Hospital of Riga,
Due to increased sensitivity of paediatric pacients to ionizing radiation in paediatric CT imaging it is important to reduce the radiation dose avoiding multiple scanning phases.
This creates a problem in assessment of abdominal organs in politrauma patients where damage of parenchymal organs and urinary tract can be present requiring both parenchymal and late excretory phase.
The split bolus technique is a solution to combine both phases in one by splitting the necessary amount of contrast...
Findings and procedure details
21 paediatric multitrauma patient was examined using split-bolus technique at Children Clinical University hospital of Riga,
from February 14,
2017 to April 14,
CT exams were performed with 4 different proportion of i/v contrast medium.
The patients were examined splitting the non-ionic iodine contrast medium iohexol of 300 mg I/ml or iodixanolumof 320 mgI/ml per dose of 1,2 ml/kg in two parts one of which was administered manually and after 7-10 minutes the other part was...
The results of all 4 used proportions shows variability of contrast patterns of structure of abdominal organs depending on the volume and proportions of injected contrast media. The optimum proportion of contrast medium for imaging paediatric patients with politrauma is 1/4+3/4 because it depicts all of the abdominal organ structures better than other proportions as this proportion provides very good or good contrast of most of abdominal structures and even those ones presenting poor contrast...
