Special PET Scan Instructions for People with Diabetes


Positron emission tomography (PET) is a nuclear medicine imaging test conducted to provide doctors with accurate basis for diagnosing a variety of diseases. It involves the injection of a special form of glucose, called 18-F fluorodeoxyglucose (18-F FDG) or simply FDG, to aid in imaging the condition of the tissues and organs. 

Because FDG is sugar, the test results are likely to be affected if the person undergoing it has diabetes, a condition characterized by high blood sugar levels. The blood will not take up FDG efficiently since it already contains too much sugar. This, however, doesn’t mean that diabetics can no longer have a PET scan. They only need to do the following preparations to make sure that the results of the test will be reliable.

MRI Scan and Neurological Disorders: Can Machine Really Detect Issues?



Mixed martial arts competitions have never been more popular throughout the United States and the rest of the world. In fact, to say that the combat sport gets the adrenaline pumping is an understatement. However, what spectators find exciting and entertaining can prove to riskier than what MMA fighters and their trainers may initially believe—and we aren’t just talking about getting beaten up. There is also a significant risk of neurological damage, which may lead to neurodegenerative disorders and movement dysfunction.

One of the most difficult aspects of diagnosing and treating neurodegenerative disorders is the fact that many symptoms are quite subtle, especially in the early stages. This often leads to delayed treatment. Fortunately, medical researchers may have found a way to detect neurodegenerative disorders early on with the help of MRI technology.
