Due to the advance development in the CT software, angiography based on the conventional catheter techniques has been replaced by the CT angiography. In order to study the contrast based CT examination, large proportion of intravenous iodinated contrast agent were required to enhance the region of interest. The enhancement of contrast in CT examination is affected by three main factors such as patient, contrast media and scanning techniques factors. The factors which are related to the patient affecting the contrast enhancement are age, sex, height, weight and cardiac output. Aim of our study is to evaluate the factors affecting on the intravenous contrast flow during chest studies. In conclusion, outstanding vascular enhancement can routinely be obtained for CT scan of the chest. The relationship between injection rate, injection duration and required vascular enhancement as shown in our study will remain an important consideration as technology improvements in CT scanning.
