Operation | The principle of positron emission tomography (PET) is that the radiation from radioactive drugs injected intravenously to the patient is recorded by external detectors placed in different directions. The isotope distributes within different tissues according to the carrier molecule (isotope labeling) and emits a positron (positively charged electron). The PET system computer then reconstructs the cross-sectional images from the display data, as does a CT scanner computer. Modern multislice PET scanners allow up to 45 slices to be obtained simultaneously at an axial distance of 16 cm. The spatial resolution of the PET system is limited to 5 mm. PET images are often combined with contrast-enhanced CT images to facilitate anatomical localization of radiopharmaceuticals. |
