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...

SPECT/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...

Hybrid 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 ...

SPECT-CT fusion in the diagnosis of hyperparathyroidism

Objective(s): In this study, we aimed to analyze the relationship between the diagnostic ability of fused single photon emission computed tomography/computed tomography (SPECT/CT) images in localization of parathyroid lesions and the size of adenomas or hyperplastic glands. Methods: Five patients with primary hyperparathyroidism (PHPT) and 4 patients with secondary hyperparathyroidism (SHPT) we...
