C Bronchiectasis white cell scan (right) - left shows a normal scan for comparison

White cell scan (C) This pair of white cell scans from different people show almost no white cells in the lungs on the left, as in a healthy person (the spleen is the ‘hottest area). The scan on the right shows grossly increased update, especially in the left lung (seen on the right). This is the typical feature of severe bronchiectasis with large amounts of neutrophils and other phagocytes present.
