  1. Even distribution of inhaled krypton gas, reflecting size and shape of lung.
  2. Even distribution of injected 99mTc MAA reflecting size and shape of lung.
  3. V image appears smaller than corresponding Q image due to reduced peripheral ventilation.
  4. Uneven distribution of inhaled krypton gas especially in dorso-caudal region.
  5. Uneven distribution of injected 99mTc MAA compared with healthy control.
  6. The color scales represent low uptake (dark blue) to high uptake (red).
