Bone metastases, often a consequence of breast, prostate, and lung carcinomas, are characterized by an increased bone turnover, which can be visualized by positron emission tomography (PET), as well as single-photon emission computed tomography (SPECT). Bisphosphonate complexes of 99mTc are predominantly used as SPECT tracers. In contrast to SPECT, PET offers a higher spatial resolution and, ow...

Fifteen months after right lobe lobectomy with adjunctive radiation therapy for squamous cell carcinoma, a patient 53-yr-old man underwent Tc-99m depreotide chest single photon emission tomography (SPECT). In addition to two focal areas of abnormally increased uptake in the right lung, the Tc-99m depreotide SPECT showed cold areas in the middle thoracic vertebrae. Photopenic areas in the 6th an...

INTRODUCTION Lack of efficacy of pharmacotherapy and physiotherapy in spinal pain syndrome is an indication for intervertebral stabilizer implantation between the processes in the lumbar segment of the spine. MATERIAL AND METHODS The group consisted of 32 patients qualified after radioisotopic single-photon emission computed tomography/computed tomography (SPECT/CT) examinations with assessme...

Objective: An image display with a standardized uptake value (SUV) scale is recommended for analyzing PET exams, thus requiring the reconstruction of accurate images both SUV measurement and visual analysis. This study aimed to determine whether such may also be obtained high-speed CZT-SPECT/CT system, further application longitudinal monitoring vertebral fractures. Materials Methods: SPECT was...

The current research aims to assess the staff and patients’ effective doses during Nuclear medicine (NM) bone scans procedures. administered activity was utilized quantify doses, while personnel’s were quantified using thermoluminescent detectors (TLD-100). average 650 (440 1440) MBq procedures SPECT gamma camera system. annual dose (mSv) estimated be 2.3 (0.1 4.9). typical patient’s 4.9 (3.6 6...

OBJECTIVES To establish a new three-dimensional quantitative evaluation method for bone metastasis, we applied bone single photon emission tomography with computed tomography (SPECT/CT). The total bone uptake (TBU), which measures active bone metastatic burden, was calculated as the sum of [mean uptake obtained as standardized uptake value (SUV) above a cut-off level] × (the volume of the lesio...

PURPOSE To determine the biodistribution of Tc-99m labeled somatostatin receptor-binding peptide (Depreotide) on planar and SPECT studies of the thorax and upper abdomen in order to improve diagnostic accuracy. METHODS AND MATERIALS Retrospectively 29 planar and SPECT studies from 28 patients (all males, average age of 65.79) were reviewed. All the patients had been referred for evaluation of...

Background: Breast cancer is the most frequent female cancer, especially in 'developed' countries. 30-85% of metastatic breast patients will develop bone metastases during course disease. The study was aimed to evaluate pattern skeletal metastasis with whole body scan using 99mTechnetium methyl diphosphonate (99m'Tc-MDP). Methods: This single center based retrospective observational conducted a...
