UNLABELLED The development of novel multimodality imaging agents and techniques represents the current frontier of research in the field of medical imaging science. However, the combination of nuclear tomography with optical techniques has yet to be established. Here, we report the use of the inherent optical emissions from the decay of radiopharmaceuticals for Cerenkov luminescence imaging (CL...

Dementia describes the loss of brain function that occurs with certain diseases, and which has the potential to affect memory, thinking, language, judgment, and behavior. Most types of dementia involve irreversible neurodegeneration, and Alzheimer's disease (AD) is the most common form. Beyond AD however, there are many other diseases that can lead to dementia including dementia with Lewy bodie...

Malignant Pleural Mesothelioma is a rare tumour that arise from the mesothelial cells of the pleura and in recent time the incidence of this disease is rising. Because of the implications for management and therapy, it is important to assess the accurate staging. 18F-fluorodeoxiglucose Positron Emission Tomography (18F-FDG PET) is become a useful tool in the diagnosis of many neoplasms, such as...

Radiopharmaceuticals can range from the small and simple (e.g. small molecules, sugars, peptides, amino acids) to the large and complex (e.g. taxol, large peptides, proteins, antibodies) and can be custom-synthesized for applications in, for example, neurology, oncology, and cardiology. Radiochemistry is the process by which such molecules are tagged with a radioisotope. Owing to the high level...

Positron emission tomography coupled with computed (PET/CT) has proven to be highly informative in the diagnosis of various malignant tumours. PET/CT examination takes into account biological and morphological data, which allow accurate tumour localisation full staging disease, respectively. Cervical cancer (CC) is one most common, high-mortality cancers women. The effectiveness CC treatment de...

Brain neoplasms constitute a group of tumors with discrete differentiation grades, and therefore, course of disease and prognosis. Magnetic resonance imaging (MRI) remains the gold standard method for the investigation of central nervous system tumors. However, MRI suffers certain limitations, especially if radiation therapy or chemotherapy has been previously applied. On the other hand, given ...

Fluorine-18 is the most frequently used radioisotope in positron emission tomography (PET) radiopharmaceuticals in both clinical and preclinical research. Its physical and nuclear characteristics (97% β(+) decay, 109.7 min half-life, 635 keV positron energy), along with high specific activity and ease of large scale production, make it an attractive nuclide for radiochemical labeling and molecu...

(44)Ti/(44)Sc radionuclide generators are of interest for molecular imaging. The 3.97 hours half-life of (44)Sc and its high positron branching of 94.27% may stimulate the application of (44)Sc-labeled PET radiopharmaceuticals. This review describes the current status of (44)Ti production, (44)Ti/(44)Sc radionuclide generator development, post-processing of generator eluates towards medical app...

Radioiodinated metaiodobenzylguanidine (MIBG) was developed in the late 1970's, at the Michigan University Medical Center, for imaging of the adrenal medulla and its diseases. Soon after, MIBG was shown to depict a wide range of tumors of neural crest origin other than pheochromocytomas/paragangliomas (Pheo/PGL) with the result that its use rapidly spread to many countries. After more than 30 y...
