Advances in Technological Design to Optimize Exposure and Improve Image Quality

摘要: Multimodality imaging is playing a key role in the clinical management of patients routine diagnosis, staging, restaging and assessment response to treatment, surgery radiation therapy planning malignant diseases. The complementarity between anatomical (CT MRI) functional/molecular (SPECT PET) modalities now well recognized fusion widely used as central piece general tree decision making. Moreover, dual-modality technologies including SPECT/CT, PET/CT nowadays PET/MR represent leading component modern healthcare facility. There have been significant advances data acquisition along with innovative approaches image reconstruction processing aim improve quality diagnostic information. However, CT procedures involve relatively high doses patient, which triggered many initiatives reduce delivered dose particularly paediatric practice.
