Development and evaluation of a new fully automatic motion detection and correction technique in cardiac SPECT imaging

Background In cardiac SPECT perfusion imaging, motion correction of the data is critical to the minimization of motion introduced artifacts in the reconstructed images. Software-based (data-driven) motion correction techniques are the most convenient and economical approaches to fulfill this purpose. However, the accuracy is significantly affected by how the data complexities, such ...

Vascular dysfunction measured by fingertip thermal monitoring is associated with the extent of myocardial perfusion defect

Background Previous studies have shown that vascular dysfunction measured by digital thermal monitoring (DTM) during an arm-cuff reactive hyperemia procedure correlates with the severity of coronary artery disease measured by coronary artery calcium in asymptomatic patients. Current study investigates the correlation between DTM and abnormal myocardial perfusion imaging (MPI). ...

Association between anxiety disorder and the extent of ischemia observed in cardiac syndrome X

Background A possible link between the heart and brain has been reported for cardiac syndrome X. Anxiety disorder could be a pathophysiological mechanism for this cardiac chest pain. To the authors’ knowledge, a quantitative analysis correlating anxiety with the extent of ischemia has not been done. Methods and Results In this pilot study, we evaluated 20 patients with typical ...

Prevalence of coronary artery disease across the Framingham risk categories: coronary artery calcium scoring and MSCT coronary angiography

Background Non-invasive assessment of subclinical atherosclerosis by means of coronary artery calcium scoring (CACS) and multi-slice computed tomography (MSCT) coronary angiography could improve patients’ risk stratification. However, data relating observations on CACS and MSCT coronary angiography to traditional risk assessment are scarce. Methods and Results In 314 consecutive ...

Type 2 diabetes is associated with more advanced coronary atherosclerosis on multislice computed tomography and virtual histology intravascular ultrasound

Background Data on coronary plaque observations on multi-slice computed tomography (MSCT) in patients with type 2 diabetes are scarce. Methods and Results In total, 60 patients (19 with diabetes) underwent 64-slice MSCT, followed by conventional coronary angiography with intravascular ultrasound (IVUS). Non-invasively, the extent of coronary atherosclerosis and 3 plaque types ...

Prospective multicenter evaluation of rapid, gated SPECT myocardial perfusion upright imaging

Background A novel three-dimensional (3D) iterative image reconstruction method (3D-OSEM) has been developed that in phantom studies yielded comparable image quality at one half the imaging time. In this study, we compared standard (STD) and rapid (nSPEED) protocols for diagnostic quality of images and quantitation of end-diastolic volume (EDV), end-systolic volume (ESV), left ...

Assessment of myocardial perfusion with Tc-99m: image is everything

Despite the multiple imaging modalities that are now available for the diagnosis and assessment of coronary artery disease, radionuclide myocardial perfusion imaging continues to enjoy widespread use due to its combination of diagnostic accuracy and well-established prognostic utility.After initial research demonstrated the feasibility of perfusion imaging with the metallic cation ...

The additive prognostic value of perfusion and functional data assessed by quantitative gated SPECT in women

Background The aim of this study was to assess the prognostic value of technetium-99m tetrofosmin gated SPECT imaging in women using quantitative gated single photon emission computed tomography (SPECT) imaging. Methods We followed 453 consecutive female patients. Average follow-up was 1.33 years (max. 2.55). Hard endpoints were cardiac death, acute myocardial infarction, or ...
