• Low dose I+ enhanced optimized AC CT |
- 2 cc/kg IV contrast (Optiray320); 1 cc/kg if <10 kg; 22 G - 2 cc/s injection, 10–20 cc saline flush, scan - No oral contrast routinely used - Arms down, elevated off table with blanket • (arms up possible, depending on pt) |
• CT scan top - > down (eyes - > thighs, vertex-toes) |
• Thickness: 1.2 mm, Pitch: 1.3 • Tube current modulation (reference mAs, weight-based): 20 mAs (< 55 kg); 35 mAs (> 55 kg) - Reconstructions: • Sag, Cor: standard algorithm • Axial: lung algorithm • Iterative Reconstructions: 2 iterations |
