Immunocompromised patients during HSCT procedure commonly need repeated MDCT examinations resulting in a high cumulative radiation dose. 3D-UTE MRI using a stack-of-spirals trajectory, enables contrast-free and radiation-free imaging of the lungs within a single breath-hold with increased signal yield due to echo times being well below parenchymal T2*. 3D-UTE MRI allows diagnostics of inflammatory consolidations and pleural effusions with high sensitivity, specificity and consistency when compared to MDCT. Moreover, 3D-UTE sequences improve detection rates of ground glass opacities in pulmonary MRI.
