OBJECTIVE There are no previous studies using single photon emission computed tomography (SPECT) scans in somatization disorder (SD) patients. The aim of this paper is to assess SPECT imaging abnormalities in SD patients and study any relation to laterality. METHOD Eleven SD patients from the Somatization Disorder Unit of Miguel Servet University Hospital, Zaragoza, Spain, not fulfilling crit...

BACKGROUND Dyspnea is a complex system with multiple etiologies, including myocardial ischemia ("anginal equivalent"). Few studies have examined the utility of stress testing to detect coronary artery disease in this setting. The purpose of this study was to examine the prevalence, severity, and prognostic value of perfusion defects detected by stress single photon emission computed tomography ...

INTRODUCTION AND OBJECTIVES The aim of this study was to compare magnetic resonance and gated-SPECT myocardial perfusion imaging in patients with chronic myocardial infarction. METHODS Magnetic resonance imaging and gated-SPECT were performed in 104 patients (mean age, 61 [12] years; 87.5% male) with a previous infarction. Left ventricular volumes and ejection fraction and classic late gadoli...

AIMS This study was conducted to investigate the incremental prognostic value of sequential use of single-photon emission computed tomography (SPECT) and coronary computed tomography angiography (CCTA) in patients with suspected coronary artery disease (CAD). METHODS AND RESULTS A total of 1295 patients with suspected CAD who underwent both CCTA and SPECT within 90 days was retrospectively re...

INTRODUCTION Interictal brain single photon emission computed tomography (SPECT) is used in the presurgical evaluation of patients with complex partial epilepsy. The aim of the present study was to compare interictal SPECT, MRI and video-electroencephalography (EEG) for seizure focus localization in patients with temporal lobe epilepsy, one year after temporal lobectomy, in order to determine t...

UNLABELLED With an increasing emphasis on quantitation of SPECT imaging and its use in dosimetry to guide therapies, it is desirable to understand the repeatability in normal-organ SPECT uptake values (SPECT-UVs). We investigated the variability of normal abdominal organ uptake in repeated (111)In-pentetreotide SPECT studies. METHODS Nine patients with multiple (111)In-pentetreotide SPECT/CT ...

BACKGROUND Facet joint disease plays a major role in axial low-back pain. Few diagnostic tests and imaging methods for identifying this condition exist. Single photon emission computed tomography (SPECT) is reported that it has a high sensitivity and specificity in diagnosing facet disease. We prospectively evaluated the use of bone scintigraphy with SPECT for the identification of patients wit...

Objective: The aim of this study was to evaluate the influences of reconstruction and attenuation correction on the differences in the radioactivity distributions in 123I brain SPECT obtained by the hybrid SPECT/CT device. Methods: We used the 3-dimensional (3D) brain phantom, which imitates the precise structure of gray mater, white matter and bone regions. It was filled with 123I solution (20...

Introduction Quality control is an important phenomenon in nuclear medicine imaging. A Jaszczak SPECT Phantom provides consistent performance information for any SPECT or PET system. This article describes the simulation of a Jaszczak phantom and creating an executable phantom file for comparing assessment of SPECT cameras using SIMIND Monte Carlo simulation program which is well-established fo...

Introduction: In this study the evaluation of a Platelet-based Maximum Penalized Likelihood Estimation (MPLE) for denoising SPECT images was performed and compared with other denoising methods such as Wavelets or Butterworth filtration. Platelet-based MPLE factorization as a multiscale decomposition approach has been already proposed for better edges and surfaces representation due to Poi...
