Multidetector Pediatric Chest CT: Practical Approach<br />
Donald P. Frush, M.D.<br />
Duke University Medical Center<br />
Introduction<br />
• Multidetector CT (MDCT) is an invaluable imaging modality<br />
for thoracic evaluation.<br />
• MDCT provides:<br />
• unique benefits. For example,<br />
• scanning completed during limited breath-holding in<br />
children<br />
• improved IV contrast enhanced scanning, especially CT<br />
angiography<br />
• Thin slices (improving z-axis resolution) with improved<br />
multiplanar and 3D depictions unique challenges<br />
• Objectives for this material on pediatric chest MDCT:<br />
• summarize the importance <strong>of</strong> topic<br />
• review the technical considerations for children,<br />
• discuss applications<br />
Importance <strong>of</strong> Pediatric Chest MDCT<br />
• Pediatric chest MDCT is important for the following reasons:<br />
• CT use is increasing: 600% increase recently predates<br />
MDCT.<br />
• CT is a widely used modality.<br />
• Estimated that currently 30-65 million CT examinations<br />
are performed in the US<br />
• 600,000 - 1.6 million CT examinations are performed<br />
in children or 4-5% <strong>of</strong> the total.<br />
• 33% in children
