Functional anatomical image fusion with a hybrid SPECT-CT an new stage of the developing nuclear medicine techniques

To obtain a function of precise anatomical localization, it is a goal that SPECT with functional sensitivity aspire to all through. Al though the SPECT hybrid sys tem with non-diagnostic CT could provided more information for clinical practice. It's better function of anatomical localization has confirmed further the role of SPECT in clinical practice. It has a good future in application that is could provide accurate image of attenuaton and function of heart in cardiovascular disease, so that in favor of diagnosis early a n d accurately. The hybrid SPECT-CT help improvedp lanning of diagnosis and therapy for patients with can cersuch as ectopic parathyroid tumours, neuroendocrine tumours, and prostate can cer soon that it could evaluate accurately position a n d characters to those primary or focus of metastases tumours. In general nuclear medicine. It could help clinicians accurately locate the source of infection and improve the sensitivity of diagnosis and Improved therapy planning optimized for each individual patient, it also provide an accurate a ssessment of the morphological-perfusion defect relationship. The SPECT-CT brought high accurateness for functional and anatomical image and so improve workflow.
