The Role of Multislice Computed Tomography in Congenital Heart Diseases in Paediatric Age Group.

"● CT examination will be done by~* 160 MDCT Toshiba Machine or 128 MDCT GE machine or 160 MDCT Philips Machine:~* We used the following parameters during cardiac CT scanning:~ * Pitch of 1.3, helical thickness of 0.5 mm and coverage of 32 cm.~ * The radiation dose set to 80-100 kvp.~ * Tube current from 10 to 40 mA/kg.~ * The gantry rotation speed at 0.35-.4 sec.~ * ECG gated Retrospective With MA modulation.~ * Wide FOV.~* A scout will be taken and dual-phase injection conducted using non ionized contrast material. The total contrast volume is 1.5-3 ml/kg.~* Scanning begins when contrast filled the LV by bolus tracking.~* All images were transferred to workstation multiplanar reformation (MPR), maximum (MIP) and minimum (MinIP) intensity projections and volume rendering images will be performed for reporting."
