To illustrate Multidetector CT manifestations of a variety of congenital pulmonary vascular malformations. To emphasize the role of multidetector CT angiography in diagnosis of pulmonary vascular anomalies.
Congenital anomalies of the thoracic vascular system are an important cause of morbidity and mortality in infants and children 1 .
Congenital thoracic vascular anomalies occur in the thoracic aorta and branch arteries,
thoracic systemic veins,
and the pulmonary veins 2 .
In this pictorial educational exhibit,
pulmonary vascular anomalies are focussed. Congenital pulmonary vascular anomalies: Pulmonary arterial anomalies Pulmonary venous anomalies Pulmonary arterial...
Findings and procedure details
MDCT Procedure Details: Computed Tomography has a vital role in diagnosing congenital vascular anomalies.
For CT pulmonary angiography (CTPA) and cardiac anomaly CT examinations,
scan is performed from lung apex till level of adrenals with a large field of view.
A 1.25-mm collimation should be used,
which can be reconstructed at 0.75- 1 mm intervals with a targeted field of view.
A pitch of 3 or 6 is required depending on the the patient's ability to hold their breath.
Average of 120 mL of...
MDCT with the use of multiplanar reconstruction enables highly accurate differentiation among pulmonary vascular abnormalities. MDCT pulmonary angiography with multiplanar and three-dimensional techniques should be the method of choice for preoperative morphologic assessment of vascular diseases in adult and pediatric patients. MDCT is an accurate method for the diagnosis of congenital anomalies involving both pulmonary arteries and veins and also for preoperative planning and post operative...
