Why is FDG-PET good at finding inflammation?
The “G” in FDG stands for glucose, which is a type of sugar. Inflamed tissues burn through a lot of energy. They take up the glucose to use as fuel. Normal tissues don’t burn through as much energy, so they take up less glucose.
When doctors are looking for inflamed or cancerous tissue, they use FDG that has been labeled with a small amount of radioactivity. The FDG is injected into a vein and is taken up by inflamed tissues as it circulates through the body. The PET camera can see how much glucose the inflamed tissue is using by measuring the radioactive particles the FDG releases.

What is the difference between pulmonary embolism and deep-vein thrombosis?
Deep-vein thrombosis is clotting in the veins deep within the body. Pulmonary embolism is often a complication of deep-vein thrombosis, which occurs when the clot travels to the lungs, blocking the flow of blood. Both conditions require immediate treatment with anticoagulant medications to help break up the clot and restore normal blood flow.
STEMI and NSTEMI are two classifications for a heart attack. Although both result from the interruption of blood supply to a part of the heart, STEMI results in ST-elevation (elevation of a cardiac enzyme) while NSTEMI does not. Unstable angina, on the other hand, is a condition characterized by chest pain or discomfort that is unexpected and usually occurs at rest. Unstable angina is often accompanied by shortness of breath, indigestion and/or dizziness. Unlike STEMI and NSTEMI, which cause muscle damage in the heart, unstable angina is not associated with muscle damage. However, unstable angina is very dangerous, may progress to a heart attack, and needs emergency treatment.
Unstable angina and NSTEMI often appear identical at first presentation. The difference can be ascertained only after an ECG and blood tests to look for markers that indicate heart muscle damage.
