Pediatric thoracic CT angiography.

One of the principal benefits of contemporary multidetector row computed tomography (MDCT) has been the ability to obtain high-quality data sets for evaluation of the cardiovascular system. The benefits of the greater number of detector rows and submillimeter image thicknesses were quickly recognized and are especially advantageous in children. For example, since imaging is performed so quickly, issues with motion are minimized.

Imaging of paediatric mediastinal masses.

A review of mediastinal masses in children is important for several reasons. First, the mediastinum is the common location for thoracic masses in children. Second, the type and frequency of masses differ in children compared with adults.

Computer-simulated radiation dose reduction for abdominal multidetector CT of pediatric patients.

Objective: Limiting CT radiation dose is especially critical when imaging children. The purpose of our study was to modify and test an accurate and safe tool for evaluating systematic dose reduction for abdominal multidetector CT (MDCT) in pediatric patients.

Materials And Methods: After validating the computer-simulation technique with a water phantom, we subjected the original digital scanning data for 26 contrast-enhanced abdominal MDCT scans (120 mA) obtained in infants and children (age range, 1 month-9 years; mean age, 3.
