Abstract
Multi-detector pulmonary CT angiography is now the first line of investigation in the diagnosis of most of the pulmonary vascular disorders. The increase in gantry speed and thinner collimation that accompanied the introduction of multi-detector CT scanners has extended the accuracy of assessment of the pulmonary vasculature to the sub-segmental level.
MDCT pulmonary angiography is a relatively available, minimally invasive investigation that can now be considered as the first line of investigation in diagnosis of pulmonary embolism with its ability to detect small emboli down to the segmental and sub-segmental level. It is of value in patients with pulmonary hypertension as it shows different signs of pulmonary hypertension as well as the possible cause. In most cases of congenital anomalies and pulmonary aneurysms pulmonary CTA provides the needed data for management in such cases.
Conclusion
The nowadays ease of the scan acquisition and the high spatial resolution of modern CT techniques make pulmonary CT angiography an investigation ideally suited for the great majority of different congenital and acquired, acute and chronic disorders of the pulmonary vasculature.
