[Flat detector computed tomography in diagnostic and interventional pediatric cardiology]

Area of Science:

• Cardiology
• Medical Imaging
• Pediatric Cardiology

Background:

• Congenital heart disease (CHD) presents complex anatomical challenges requiring advanced imaging during catheterization.
• Conventional angiography has limitations in visualizing intricate cardiac structures.

Purpose of the Study:

• To evaluate the utility of flat detector computed tomography (FD-CT) in catheterization procedures for patients with congenital heart disease.
• To assess the image quality and clinical value of FD-CT across various anatomical regions.

Main Methods:

• Retrospective analysis of 176 catheterization cases using FD-CT between January 2010 and April 2012.
• Image quality was assessed using a five-point Likert scale.
• Application reports were generated for key cardiovascular structures, and contrast dye consumption and radiation dose were evaluated.

Main Results:

• FD-CT was rated superior to conventional angiography in 96.6% of cases.
• Image quality was deemed "very useful" in 77.3% and "essential" in 3.4% of cases.
• Mean contrast dye volume was 1.76 ml/kg, and mean dose-area product was 99 µGym².

Conclusions:

• FD-CT is a valuable auxiliary tool for diagnostic and interventional catheterization in CHD.
• It provides high-resolution, 3D visualization of extracardiac structures.
• FD-CT supports diagnosis, surgical planning, and 3D navigation in complex pediatric cardiac cases.
