introduction spect projections are contaminated by scatter radiation, resulting in reduced image contrast and quantitative errors. backscatter constitutes a major part of the scatter contamination in lower energy windows. the current study is an evaluation of the effect of backscatter material on fwhm and image quality investigated by monte carlo simulation. materials and methods simind program...

T his statement of the Committee on Advanced Cardiac Imaging and Technology of the Council on Clinical Cardiology addresses the use of positron emission tomography (PET) as a clinical tool for the diagnosis and management of patients with coronary artery disease. Over the past decade PET technology has evolved to the point that clinical PET studies can be performed safely and efficiently in the...

We report a 69-year-old male patient whose motor aphasia started at the age of 61. The language disability remained isolated and progressed over a period of eight years without any additional cognitive deficits. Computed tomography (CT) and magnetic resonance imaging (MRI) showed moderate cortical atrophy with frontal dominance. Single photon emission tomography (SPECT) showed hypoperfusion in ...

Our aim was to estimate the volumes of homogeneous structures whose contrast / intensity was changing with time, using only few (here 4) projections of the structures. Each projection was recorded over a period of time and consisted of a sequence of images. The projections of the structures were first separated by factor analysis of the total projections. Then each structure was reconstructed i...

A 71-year-old male patient was diagnosed with papillary carcinoma follicular variant after bilateral total thyroidectomy and radioactive iodine treatment applied. The post-therapeutic whole-body scan demonstrated a focal 131I uptake in the right lobe of liver upper quadrant abdomen. Single-photon emission computed tomography/computed tomography (SPECT/CT) performed to determine precise localiza...

Shown by Single Photon Emission Computed Tomography Imaging To the Editor: O‘Rourke and colleagues1 describe a case of resolution of stress-induced myocardial ischemia during aggressive medical therapy demonstrated by single photon emission computed tomography (SPECT) imaging. They conclude that a 1-year period of aggressive medical treatment led to this favorable result in a patient, who initi...

Radionuclide methods are one of the most modern methods of functional diagnostics of diseases of the cardiovascular system that requires the use of mathematical methods of processing and analysis of data obtained during the investigation. Study is carried out by means of one-photon emission computed tomography (SPECT). Mathematical methods and software for SPECT data processing are developed. T...

Malignant struma ovarii is a rare disease in gynecology and the optimal treatment regimen for the tumor remains obscure. We present a patient who had malignant struma ovarii with peritoneal implants and pelvic structures and liver metastases shown on posttreatment iodine I-131 single-photon emission tomography (SPECT) and low-dose computed tomography (CT). The roles of I-131 ablation in the man...

Introduction: Scintigraphy has been considered as a useful tool in the assessment of meniscal tears. Our objective was to assess the accuracy of single photon emission tomography (SPECT), using MRI as the gold standard, in the diagnosis of meniscal tears. Materials and Methods: Between January 2003 and February 2005, 48 patients were studied with SPECT and MRI. Results: The respective sensitivi...
