Medical imaging is a technique or process to obtain images of body image, especially in the body for medical purposes. Medical imaging is run in order to know the shape and function of organs, certain substances and metabolism process in the body. While this has been used for purpose mentioned such Positron Emission Tomography (PET), Magnetic Resonance Imaging (MRI), Ultrasound Tomography, Nuclear Medicine and Computed Tomography (CT).

One important thing in the development of medical imaging is development of contrast to increase the coverage and quality of the results obtained. In this field, the development of molecular design innovation that promises vast opportunities.

In the 1970s, Ido Tatsui from Brookhaven National Laboratory for the first time introducing a form of glucose analog compound 2-fluoro-2-deoxy-D-glucose (FDG) which is bounded with radioisotope fluoride-18 (18F-FDG). Fluorine-18 is radioisotope Positron transmitter with part-time 110 minutes. In August 1976, for the first time 18F-FDG is tried to two volunteers to get a human brain based on glucose metabolism. more…
