Bloodvessel deviations
Conditions
Interventions
Randomly, 15 Patients are assigned to undergo the CARE kV protocol using the
Combined Applications to Reduce Exposure (CARE kV) tool of Siemens,
CARE kV automatically suggest kV and effective mAs to
a tube current of 120
kV and 100 ml contrast medium [9].
In our previous study we used a test bolus reduction protocol with a test bolus
of 10 mL contrast medium (ioversol 350, 350 mg iodine per mi
Optiray
350, Tyco Health care, Mansfield, Mass) to synchronize the data acquisition
with the arrival of contrast material in the abdominal aorta. The test bolus
was followed by a bolus injection of
