Congenital Diaphragmatic Hernia (CDH) is associated with lung hypoplasia reflected in decreased pulmonary microcirculation and secondary pulmonary hypertension. Using tissue similarity maps (TSM), Haacke et al. demonstrated mapping vascular behaviour and calculating relative pulmonary blood volume (rPBV) maps in perfusion weighted imaging of the brain. In this study we have investigated the significance of the TSM technqiue for lung perfusion imaging in two-year old children after CDH repair.
