Objective(s): Nuclear medicine technologists in Japan often perform additional single-photon emission computed tomography (SPECT) with or without computed tomography (CT) after whole-body imaging for bone scintigraphy. In this study, we wanted to identify the bone scanning protocols used in Japan, together with the current clinical practices. Methods:...

carcinoid tumor is a slow-growing type of neuroendocrine tumor, originating in the enterochromaffin cells and secreting mainly serotonin. the diagnosis is based on clinical symptoms, hormone levels, radiological and nuclear imaging, and histological confirmation. the clinical symptoms are characterized by flushing, diarrhea, abdominal pain, telangiectasia and/or bronchoconstriction. however, mo...

widespread studies on tumor diagnosis has led to the development of techniques with greater sensitivity and improved specificity for detection of occult and small subclinical tumors. tumor imaging by radiolabeling of tumor-specific antibodies (immunoscintigraphy) or tissue specific biochemical agents (receptor imaging) and especially physiologic imaging with positron emitters (pet), have opened...

Introduction: Dual-modality contrast agents, such as radiolabeled nanoparticles, are promising candidates for a number of diagnostic applications, namely SPECT imaging with MR imaging. So the aim of study was evaluating potential of Chitosan-Coated Magnetic Nanoparticles(SPION) labeled with 99mTc as new Dual-modality probes for liver Imaging. Materials and Methods:</st...

Introduction: Describe the profile of patients referred for computed tomography (CT) likely to be scanned with scintigraphy imaging in Togo. Methods: Prospective study carried out from May 15 to August 15 2020 including patients referred for non-traumatic CT scans (excluding strokes) in all the radiology centres in Togo with operational ...

Background: Obtaining high quality images in Single Photon Emission Tomography (SPECT) device  is the most important goal in nuclear medicine. Because if image quality is low, the possibility of making a mistake in diagnosing and treating the patient will rise. Studying effective factors in spatial resolution of imaging systems is thus deemed to be vital. One of the most important factors in S...

Medicine is now undertaking a paramount revolution that will alter the nature of healthcare from reactive to proactive. It is imperative to integrate experimental and computational investigation in order to appreciate complex biological systems in the era of precision medicine. In light of this revolution, we necessitate to precision medicine means such as systems approaches (genomics, radiogen...

The role of the nuclear medicine has changed, from the early days when it was the only alternative to x-rays, to the present, when nuclear images are interpreted in light of specific metabolic processes, not anatomy. The development of specific receptor targeting radiopharmaceuticals, markers of viability using PETor SPECT, analogues of neurotransmitters etc., have placed the nuclear medi...
