Low-dose time-resolved contrast-enhanced magnetic resonance angiography (time-resolved CEMRA) and multi-phase high spatial resolution CEMRA (conventional CEMRA) often provide complementary information in patients with congenital heart disease (CHD). The aim of the present study was to evaluate the diagnostic role of time-resolved and conventional CEMRA in the assessment of Glenn-Fontan shunts in CHD patients. In our retrospectively selected patient group, the combination of time-resolved and conventional CEMRA allowed for comprehensive assessment of Glenn-Fontan shunts. Moreover, time-resolved CEMRA substantially increased the diagnostic confidence in the assessment of pulmonary perfusion via the shunts.
