The greatest health problem in sub-Saharan Africa is the complex of HIV and TB. PET has been primarily developed to look at cancer but can PET be used for this major health problem. F-18FDG has a high sensitivity in TB but the pattern of uptake is not specific. Attempts to improve the specificity of F-18 FDG imaging in the context of TB by using dual time scanning has not proved useful. There i...
A new preprocessing clustering technique for quantification of kinetic PET data is presented. A two-stage clustering process, which combines a precluster and a classic hierarchical cluster analysis, provides data which are clustered according to a distance measure between time activity curves (TACs). The resulting clustered mean TACs can be used directly for estimation of kinetic parameters at ...
Intraocular choroidal metastasis is a very rare cause of blindness. Choroidal hemangioma and melanoma are other causes that may mimic the condition. Carcinoma of breast is the most common primary malignancy that accounts for choroidal metastasis in females and carcinoma of lung is the most common cause in males. Other primary neoplasms which can uncommonly metastasize to the choroid are testis,...
BACKGROUND Although cardiac magnetic resonance (CMR) and positron emission tomography (PET) detect different pathological attributes of cardiac sarcoidosis (CS), the complementary value of these tests has not been evaluated. Our objective was to determine the value of combining CMR and PET in assessing the likelihood of CS and guiding patient management. METHODS AND RESULTS In this retrospect...
Neuroendocrine tumors (NETs) are distinctive tumors which arise from cells which have neural and hormonal origins. The most common clinically-encountered NETs are gastroenteropancreatic tumors (GEP NETs), lung carcinoids, pheochromocytoma, and medullary thyroid carcinoma. Imaging plays a key role in the evaluation of these tumors including detection, staging, response assessment, and prognostic...
Circulating tumor cells (CTCs) play an essential role in metastasis and serve as important prognostic biomarker. The technology of CTC labeling detection vivo can greatly improve the research cancer therapy. However, there is no to detect CTCs clinic. In this study, we demonstrate that 2-[N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl) amino]-2-deoxy-d-glucose (2-NBDG), a 2-deoxy-glucose analog, work ind...
INTRODUCTION Fluorodeoxyglucose positron emission tomography scanning has an established role in the diagnostic work-up of many malignant diseases and also in the evaluation of cancer treatment response. Fluorodeoxyglucose positron emission tomography may, however be non-specific as infectious processes are depicted as well. CASE PRESENTATION We present a patient with longstanding leg pain an...
