Conclusion
Even today Level II antepartum scans are not a routine at many places.
As a result,
many congenital heart diseases go undetected.
Moreover,
patients with these anomalies may have distorted thoracic cage anatomy and/or cardiac malposition that limit the usefulness of echocardiogram.
These patients benefit immensely by MDCT.
Low dose MDCT with paediatric protocol has the advantage of less radiation in patients who are going for repeated studies for congenital heart disease.
There is better delineation of aortic and pulmonary vessels morphology by three dimensional reconstructions on MDCT.
Pulmonary and systemic venous returns,
measurement of coarctation of aorta,
visualisation of major aortopulmonary collaterals are also accurately done on CT angiography.
There is better assesment of patients after shunt procedures.
Reformatted images from MDCT can accurately and systematically delineate the normal and pathologic morphologic features of the cardiovascular structures.
The capabilities of MDCT imaging for depicting this anatomy ensure an increasing role for radiologists.
Hence,
Low dose high resolution MDCT images manipulated by Maximum Intensity Projections/Volume Rendered/Multiplanar reformations depict the congenital cardiac anomalies with greater ease and understanding,
thus helping in institution of correct and timely interventions and treatment.
