Rubidium-82 is used for positron emission tomography. New applications include positron emission tomography and particle physics. EEG has also been combined with positron emission tomography. Imaging tests such as computerised tomography (CT scan), positron emission tomography (PET CT). Positron emission tomography (PET) is another imaging technology that aids researchers. Imaging tests like X-ray, ultrasonography, computerised tomography (CT), magnetic resonance imaging (MRI) and PET CT. Oxygen-15 is an isotope of oxygen, frequently used in positron emission tomography, or PET imaging. N is used in positron emission tomography (PET scan). Specific methods include industrial computed tomography. Radioactive verapamil can be used for measuring P-gp function with positron emission tomography. C is one of the isotopes often used in positron emission tomography. Cu is used in Cu-PTSM as a radioactive tracer for positron emission tomography. Nitrogen-13 (N) is a radioisotope of nitrogen used in positron emission tomography (PET). Computed tomography (CT scan) is often used.
