Spiral CT and 3D Image Reconstruction of Vascular Rings and Associated Tracheobronchial Anomalies

Anomalies of the fetal aortic arch: a novel sonographic approach to in‐utero diagnosis

“…Only recently have the use of spiral CT angiography and MRI modalities for this purpose been described [3][4][5] . Conversely, during fetal life, we found that the hypoechoic trachea containing amniotic fluid may serve as an accurate and reliable anatomic landmark for direct diagnosis of the side of the aortic arch.…”

“…Some anomalies of the aortic arch, particularly those with aberrant branching, may form vascular rings, causing clinical symptoms from tracheal or esophageal compression 1,2 . Various types of congenital aortic arch abnormalities have been described; however, most have been reported in the pediatric or radiological literature using magnetic resonance imaging (MRI) and spiral computed tomography (CT) [3][4][5] . Although current prenatal ultrasound technology facilitates identification of many congenital heart defects from early stages of gestation 6 , no information is available regarding aortic arch anomalies during fetal life.…”

The value of MRI in diagnosing vascular abnormalities causing stridor

“…Transoesophageal CDE has not to our knowledge been studied in this setting. Echo-planar MRI, electron-beam CT and helical CT are new ultra-fast techniques that allow acquisition in one breath-hold, but have to our knowledge not been used in this setting [12,13,26,31].…”

Modern imaging of the tracheo-bronchial tree

“…CT has proven useful in adequate identification of these anomalies in the pediatric age group [56][57][58] .…”
