V/Q scanning using SPECT and SPECT/CT

First Author: Roach PJ, Last Author: Bailey DL

Technegas is an ideal agent for ventilation SPECT because of its small particle size (30–60 nm), resulting in greater alveolar penetration and less central deposition than a nebulizer-produced aqueous radioaerosol such as 99mTc-DTPA
