ow-dose MSCT sharpens pediatric lung images

A respiratory-gated, low-dose, 16-slice CT imaging technique successfully depicts the neonatal lung during continuous breathing, according to research presented at the 2004 RSNA meeting in Chicago.

Dr. Patrik Rogalla and colleagues from Charite Hospital in Berlin used 10 mAs at 120 kVp, 2 to 4.8 pitch, and 0.5-mm slices. They measured total volumes for the left and right pulmonary airways during breathing in 20 newborns and infants.

The technique allowed for in-depth examination of global lung function parameters, as well as separate analysis of both lungs and individual lobes, according to Rogalla.
