Low-dose CT angiography for evaluation of great vessels and airway in arterial tortuosity syndrome

Arterial Tortuosity Syndrome: An Approach through Imaging Perspective

“…However, on the whole, MDCT evaluation appears to be the best choice at the moment for rapid and comprehensive evaluation of ATS. [7] Illustrations of this work are based on sporadic cases with classical clinical signs and imaging observations and from the cohort of patients with mutations in the SLC2A10 gene (chromosome 20q13). [25] Most of the MDCT illustrations in this essay belong to a single patient, emphasizing the wealth of information obtained from a single MDCT study.…”

Pediatric and Adult Congenital Heart Disease Imaging

“…Although the capabilities of cardiovascular MR and CT are similar in the evaluation of extracardiac thoracic vasculature, CT does have a spatial resolution advantage in the evaluation of airway and lung parenchymal abnormalities. Faster data acquisition with a substantial reduction in radiation exposure is achievable in the newer multidetector CT scanners using low‐dose protocols and strict adherence to the ALARA (as low as reasonably achievable) principle 5 . Prospective gating, high pitch, low tube power and current, and automated dose reduction and reconstruction algorithms enable these improvements.…”

However, ionizing radiation remains an important concern, especially in the pediatric age group, due to the serial imaging requirements of congenital heart disease.…”
