| Abstract | Molecular imaging has witnessed great progress in the field of oncology over the past few decades. Several radioactive tracers, especially 18F-FDG (Fluorine18 - labelled fluorodeoxyglucose) have found widespread clinical applications in oncologic imaging. However, 18F-FDG has certain limitations which result in important pitfalls and cause diagnostic dilemma. In recent times ,radiolabelled amino acid (AA) tracers are particularly promising in these areas where utility of 18F-FDG PET/CT (Positron emission tomography with computed tomography) imaging has been limited. These include evaluation of brain tumors, neuroendocrine tumors, and prostate cancer. Radiolabelled AA tracers such as 18F-FDOPA, 18F-FET have found wide applications in brain tumor imaging which, unlike 18F-FDG concentrate in the tumor tissue to a greater extent than normal brain tissue , thus providing accurate information about tumor volume and boundaries. 18F-FDOPA is also useful in evaluation of neuroendocrine tumors (NETs). Tracers such as 18F-FACBC (Fluciclovine) and 18F-FACPC are used in imaging of prostate cancer and provide valuable information of locoregional, recurrent and metastatic disease. Key Words : Radiolabelled , Amino Acid , PET/CT, Imaging, Oncology. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
