UNLABELLED SPECT with (18)F-FDG has emerged as an alternative to dedicated PET for the assessment of myocardial viability. However, whether FDG SPECT can reliably quantify the extent of viable and scarred myocardium is uncertain. The aim of this study was to investigate whether SPECT with an (18)F-labeled agent would provide information on defect size similar to that provided by dedicated PET. ...

The medical cost associated with back pain in the United States is considerable and growing. Although the differential diagnosis of back pain is broad, epidemiological studies suggest a correlation between adult and adolescent complaints. Injury of the pars interarticularis is one of the most common identifiable causes of ongoing low back pain in adolescent athletes. It constitutes a spectrum o...

The 11C-labeled tracer meta-hydroxyephedrine (11C-HED) is a noradrenaline analog that was developed to visualize the sympathetic nervous system with PET. Initial clinical studies show a rapid uptake of 11C-HED in localized tumors of this system. Whole-body imaging with 11C-HED PET is now possible as PET/CT scanners allow a rather short examination time. The aim of this study was to evaluate the...

A 62-year-old male patient with previous history of myocardial infarction, akinetic myocardial segments, and an ejection fraction of 31% with the NYHA class III category was selected for the autologous bone marrow (ABM)-derived mononuclear cell fraction injection during CABG surgery. Nitrate augmented myocardial tracer uptake was imaged by ECG gated SPECT pre- and 1 year post-ABM therapy, using...

Over the last decades, great strides were made in the development of novel implants for the treatment of bone defects. The increasing versatility and complexity of these implant designs request for concurrent advances in means to assess in vivo the course of induced bone formation in preclinical models. Since its discovery, micro-computed tomography (micro-CT) has excelled as powerful high-reso...

Attenuation correction is necessary for quantification in micro-single-photon emission computed tomography (micro-SPECT). In general, this is done based on micro-computed tomographic (micro-CT) images. Derivation of the attenuation map from magnetic resonance (MR) images is difficult because bone and lung are invisible in conventional MR images and hence indistinguishable from air. An ultrashor...

A 72-year-old male with a history of prostate cancer and high prostate specific antigen levels underwent 99mtechnetium-methylene diphosphonate (99mTc-MDP) single-photon emission computed tomography/computed tomography (SPECT/CT), to identify bone metastasis. The patient possessed no previous history of serious illnesses or surgical procedures and no family history of malignancies. A whole-body ...

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, 45 patients were studied with SPECT and MRI. Results: The respective sen...
