Have you suffered time and time again in the hospital with CT, MRI, ultrasound, X-ray, biochemical tests, etc., consuming precious time, a lot of energy and expensive medical expenses? Some people even pay the price of life …… A large number of domestic and international economic studies have shown that PET/CT examinations can significantly save medical costs if the costs and benefits of PET/CT examinations are analyzed comprehensively. This is because PET/CT examinations allow for a more accurate diagnosis of patients and enable them to receive timely and effective treatment, avoiding many inappropriate examinations, misdiagnoses and treatments, and as a result, a significant overall saving in medical costs. At the same time, it reduces the patient’s pain caused by inappropriate treatment and improves the quality of life.
