![]() ![]() This is explained by the increasing availability of multidetector CT scanners and the ability of the technique to provide rapid, high-quality image acquisition. The preference for particular methods depends on the local availability of each modality and on the clinical scenario, taking into account the degree of invasiveness and potential associated morbidities, including those from exposure to ionizing radiation.ĬT has developed rapidly as an imaging modality. In practice, all these techniques are routinely employed, since no single modality can fully replace another. Imaging modalities available in children may be classified as invasive (eg, intra-arterial digital subtraction angiography and endoscopy) and noninvasive (eg, ultrasound, X-ray, computed tomography, nuclear medicine, positron emission tomography, and MRI). Clinical decision-making must be based on the requirements of each patient, guided by the latest sources of information available, including local guidelines and newly published trial data. The recommendations expressed in this review are intended solely as general guidance on best practice in pediatric MRI. Reflecting recent clinical trial activity, the role of gadolinium-based contrast media in pediatric MRI receives particular attention. The review is not intended to be comprehensive, but focuses on areas of topical interest while noting areas for further investigation. This review article reports current perceptions on the practice of MRI in children, based on discussions and consensus statements developed at an international expert meeting, attended by nine pediatric radiologists from internationally recognized radiology centers in Canada, Germany, Italy, South Korea, Spain, Sweden, and the UK, combined with follow-up collegiate revisions during manuscript development. However, a number of open issues remain, indicated by the large variations in practice between centers. Until recently, evidence to direct best practice in pediatric MRI was based largely on adult studies, but pediatric-specific data are now increasingly available. Gadolinium-based contrast media enhance the efficacy of MRI for many applications. Magnetic resonance imaging (MRI) is an important modality for diagnosing and monitoring a wide range of childhood diseases. The choice of most appropriate contrast medium should be based on criteria of safety, tolerability, and efficacy, characterized in age-specific clinical trials and personal experience. ![]() Gadolinium-based contrast media are recommended for enhancing imaging quality. Awareness of age-specific adaptations in MRI technique can optimize image quality. Discussion among the experts concluded that MRI is preferred over ionizing-radiation modalities for many indications, with advantages in safety and efficacy. Review of the literature indicated that few published data provide guidance on best practice in pediatric MRI. Nine leading pediatric radiologists from internationally recognized radiology centers convened at a consensus meeting in Bordeaux, France, to discuss applications of contrast-enhanced MRI across a range of indications in children. This article reviews recent developments in pediatric contrast-enhanced MRI and offers recommendations on current best practice. Guide-line changes, for example on contrast-medium choice, require continued practice reappraisal. Practice varies widely between centers, reflecting the rapid pace of change and the need for further research. Magnetic resonance imaging (MRI), frequently with contrast enhancement, is the preferred imaging modality for many indications in children. ![]()
