Fluorine 18-deoxyglucose (18FDG) is often used in Positron Emission Tomography (PET). PET imaging is one of the useful tool which is used to cancer detection and management. PET growth is limited due to problems that depend on the production of Fluorine-18.Imaging results are strongly dependent on the information of nuclear reaction cross section data. This study is done to calculate the stopping power, RCSDA, simulated and distributed absorbed dose of F-18, in water. In order to access these goals, we use the Geant4/Gate simulation and the Bethe-Bloch theory model. The results of this simulation and this theory model are in good agreement with each other .The main point of this paper is the presentation of a theoretical approach to the production of Fluorine-18 by using protons production through the main nuclear fusion reaction and the side fusion reaction uses helium-3 as a catalyzed.
Warfarin one of the most commonly used anticoagulants in the world is affected by the vitamin K levels in the body, which in turn depends upon many factors like drugs and diet. Here we present a case of a drug interaction between 2 commonly drugs especially in the elderly population. In this case Lactulose interacts with absorption of vitamin K from the gut and thereby potentiating the effect of warfarin toxicity. Hence it is important for every physician to be aware of this drug interaction and warn their patients regarding the same.
