Diseased cells in Your system soak up much more of the radiotracer than balanced types do. These are generally referred to as “scorching places.” The PET scanner detects this radiation and makes photographs from the affected tissue. A PET/CT scan brings together X-ray photos from the CT scan with PET scan illustrations or photos. Shenzhen CT Pet Supplies Co., Ltd.
