Single-photon emission computed tomography/computed tomography (SPECT/CT) has
emerged during the past decade as a means of correlating anatomical information from CT …

Attenuation is believed to be one of the major causes of false-positive cardiac single-photon
emission computed tomographic (SPECT) perfusion images. This article reviews the physics …

Background—Soft tissue attenuation is a prominent cause of single-photon emission
computed tomography (SPECT) imaging artifacts, which may result in reduced diagnostic …

Dual-modality imaging is an in vivo diagnostic technique that obtains structural and
functional information directly from patient studies in a way that cannot be achieved with …

Objectives: We sought to demonstrate the safety of stress-only perfusion imaging among
patients with low to medium probability of coronary disease being evaluated for chest pain …

Clinicians now rely heavily on the results of single-photon emission computed tomography
(SPECT) myocardial perfusion imaging for diagnosing coronary disease and for planning …

Attenuation is believed to be one of the major causes of false-positive cardiac single-photon
emission computed tomographic perfusion images. This article provides an introduction to …

Background. The diagnostic accuracy of cardiac single photon emission computed
tomography (SPECT) is limited by image-degrading factors, such as heart or subject motion …

Rather than the introduction of a heralded technologic advancement in cardiac SPECT
imaging challenging the accuracy of PET perfusion imaging, the commercial introduction of …

For proper attenuation correction of SPECT images, a set of 3D attenuation maps specific to
the imaging slices is needed. Among the many different approaches for deriving the …
