introduction: almost all malignant tumors have the potential to eventually produce bone metastasis. the aim of the current study was to report the distribution pattern and imaging characteristics of bone metastases detected by conventional whole body bone scintigraphy in patients with different types of malignancies and to assess their relationship with the complaint of bone pain. methods: as ...

Stanford University, Department of Radiology, Division of Nuclear Medicine and Molecular Imaging, USA Here we prospectively compared the combined 18F NaF/18F FDG PET/ MRI against 99mTc-MDP in patients with breast and prostate cancers. Twelve patients referred for 99mTc-MDP bone scans were prospectively enrolled from Oct 14 Jan 15. The cohort included 6 men with prostate cancer and 6 women with ...

In order to develop a possible C-X-C chemokine receptor type 4 (CXCR4) imaging agent for oncological scintigraphy, [(67)Ga]-labeled 1,1'-[1,4-Phenylene-bis(methylene)]bis(1,4,8,11-tetraazacyclotetradecane) ([(67)Ga]-AMD3100) was prepared by using [(67)Ga]GaCl3 and AMD-3100 for 2 h at 50 °C (radiochemical purity: >95% ITLC, >99% HPLC, specific activity: 1800-2000 TBq/mmol) in acetate buffer. The...

Objective: The purpose of the present study was to evaluate the accuracy of double phase Tc sestamibi scintigraphy in the assessment of parathyroid glands in patients with hyperparathyroidism and to compare this method with the high-resolution ultrasonography. Methods: From August-1998 through August-2000, we performed Tc -MIBI scintigraphy (MIBI) and neck ultrasonography in 35 patients who wer...

OBJECTIVES Although different noninvasive tests have been proposed for detecting coronary artery disease (CAD) in patients with hypertension and chest pain symptoms, the relative performance of the available techniques has not been systematically assessed. BACKGROUND Patients with hypertension frequently complain of chest pain and exhibit ischemic-like ST segment changes on the exercise elect...

Necrotizing otitis externa is a potentially lethal infection that starts in the external auditory canal and may progress to the skull base. It happens in elderly diabetic patients and is associated to a high morbi-mortality rate. The major causal agent is Pseudomonas aeruginosa, in 96 to 98% of the cases. The infection extends from the osteocartilaginous junction to the temporal bone by means o...

BACKGROUND The use of cardiac implantable electronic devices (CIED) is increasing, and their associated infections result in significant morbidity and mortality. The introduction of better cardiac imaging techniques could be useful for diagnosing this condition and guiding therapy. Our objective was to systematically assess the diagnostic accuracy of Fluor-18-fluorodeoxyglucose positron emissio...

A. Aerosol Ventilation Scintigraphy A diagnostic imaging test that records the bronchopulmonary distribution of an inhaled radioactive aerosol within the lungs. B. Gas Ventilation Scintigraphy A diagnostic imaging test that records the pulmonary distribution of a radioactive gas during breathing maneuvers. C. Pulmonary Perfusion Scintigraphy A diagnostic imaging test that records the distributi...

UNLABELLED We evaluated the clinical utility of positive somatostatin receptor scintigraphy in patients with medullary thyroid cancer (MTC). METHODS Twenty-four MTC patients with increased calcitonin levels underwent somatostatin receptor scintigraphy using 111In-pentetreotide (120-200 MBq) with early (4 hr after injection) and delayed (24 hr) whole-body scans and liver SPECT imaging. In Grou...
