What is a PET/CT scan? Positron Emission Tomography (PET) and Computed Tomography (CT) scans are both standard imaging tools that physicians use to pinpoint disease states in the body. A PET scan images the cellular activity of the body at a very early stage, often before anatomical changes take place.
Tularemia is a rare infectious disease that typically attacks the skin, eyes, lymph nodes and lungs. Tularemia â also called rabbit fever or deer fly fever â is caused by the bacterium Francisella tularensis.
Alpha thalassemia is a blood disorder that reduces the production of hemoglobin. Hemoglobin is the protein in red blood cells that carries oxygen to cells throughout the body. In people with the characteristic features of alpha thalassemia, a reduction in the amount of hemoglobin prevents enough oxygen from reaching the body's tissues. Affected individuals also have a shortage of red blood cells (anemia), which can cause pale skin, weakness, fatigue, and more serious complications.
