Table 1 Protocol Details – I+ low dose AC CT

From: How we read pediatric PET/CT: indications and strategies for image acquisition, interpretation and reporting

• 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
