Pediatric nuclear medicine and pediatric radiology: Modalities, image quality, dosimetry and correlative imaging: New strategies

摘要

To improve clinical practice is our daily duty as specialists in radiology and in nuclear medicine. When a clinician asks us to perform an imaging examination, we have to advise that clinician about the best test or imaging strategy to study the clinical problem. Risk-to-benefit ratio and the ALARA principle have to be weighed, as well as modality and cost.Hybrid imaging is now the standard in nuclear medicine. The use of multimodality cameras such as SPECT/CT, PET/CT and PET/MR has been revolutionary 1-4. The key is finding the exact location of functional or metabolic lesions. But adding CT increases the dosimetry 5-7, requires more detailed knowledge of imaging anatomy and depends on collaboration between radiologists and nuclear medicine specialists.
