Open AccessAs fast as an X-ray: real-time magnetic resonance imaging for diagnosis of idiopathic scoliosis in children and adolescents
Idiopathic scoliosis is common in adolescence. Due to the rapid growth of the spine, it must be monitored closely with radiographs to ensure timely intervention when therapy is needed. As these radiographs con...

Open AccessBrain deposition of gadobutrol in children—a cross-sectional and longitudinal MRI T1 map** study
Depositions of linear gadolinium-based MRI contrast agents are readily visible in T1-weighted MRIs of certain brain regions in both adults and children. Macrocyclic contrast agents such as gadobutrol have so f...

Open AccessChest examinations in children with real-time magnetic resonance imaging: first clinical experience
Real-time magnetic resonance imaging (MRI) based on a fast low-angle shot technique 2.0 (FLASH 2.0) is highly effective against artifacts caused due to the bulk and pulmonary and cardiac motions of the patient...

Open AccessOutpacing movement — ultrafast volume coverage in neuropediatric magnetic resonance imaging
Conventional MRI sequences are often affected in neuropediatric imaging by unavoidable movements. Therefore, children younger than 6 years usually have to be examined under sedation/anesthesia. A new real-time...

Open AccessThe current status and further prospects for lung magnetic resonance imaging in pediatric radiology
Lung MRI makes it possible to replace up to 90% of CT examinations with radiation-free magnetic resonance diagnostics of the lungs without suffering any diagnostic loss. The individual radiation exposure can t...

Do we need gadolinium-based contrast medium for brain magnetic resonance imaging in children?
Brain imaging is the most common examination in pediatric magnetic resonance imaging (MRI), often combined with the use of a gadolinium-based contrast medium. The application of gadolinium-based contrast mediu...
