Selected CTA findings showed significant associations with the clinical course of PE and may thus be used as predictive parameters.

Adolescents with spinal injuries receive a cumulative effective dose equal to that of adult trauma patients and nearly three times that of pediatric trauma patients. Areas of focus in lowering cumulative effective dose should be appropriate initial estimation of trauma severity and careful selection of CT scan parameters.

Patient age and weight showed significant impact on vascular attenuation and image quality in pulmonary CTA with bolus tracking and ATCM, whereas patient sex and different peripheral catheters did not significantly influence image parameters.

Imaging of the distal lower limb in this special patient population requires a large number of patients to obtain enough comparative images where non-contrast-agent-dependent factors do not disturb contrast agent efficacy. The ITT analysis showed at least non-inferiority of gadobutrol in comparison to gadoterate. The avoidance of imaging artefacts demonstrates a better outcome for gadobutrol.
