The influence of misregistration between CT and SPECT images on the accuracy of CT-based attenuation correction of cardiac SPECT/CT imaging: Phantom and clinical studies
Introduction: Integration of single photon emission computed tomography (SPECT) and computed tomography (CT) scanners into SPECT/CT hybrid systems permit detection of coronary artery disease in myocardial perfusion imaging (MPI). Misregistration between CT and emission data can produce some errors in uptake value of SPECT images. The aim of this study was evaluate the influence...
متن کاملHybrid PET/CT and SPECT/CT Imaging
1.1 Definition of nuclear medicine, molecular imaging and hybrid imaging Nuclear Medicine uses radioactive probes commonly referred to as tracers for the diagnosis and treatment of diseases. Monitoring the metabolic fate of nanomolar amounts of radiolabeled substances by tracking their photon emission with SPECT (Single Photon Emission Tomography) and PET (Positron Emission Tomography) was the ...
متن کاملImpact of Novel Incorporation of CT-based Segment Mapping into a Conjugated Gradient Algorithm on Bone SPECT Imaging: Fundamental Characteristics of a Context-specific Reconstruction Method
Objective(s): The latest single-photon emission computed tomography (SPECT)/computed tomography (CT) reconstruction system, referred to as xSPECT Bone™, is a context-specific reconstruction system utilizing tissue segmentation information from CT data, which is called a zone map. The aim of this study was to evaluate theeffects of zone-map enhancement incorporated into the ordered-subset conjug...

متن کاملSPECT/CT imaging of bone
The skeleton is a metabolically active organ that undergoes continuous remodelling throughout life. Normal healthy bones are dynamic structures with inherent basal levels of turnover sustained by balanced osteoblastic and osteoclastic activity. Increased bone turnover (ie osteoblastic activity) is the central mechanism of attempts at bone healing in case of any insult, whether it is benign or m...
