The nuclear medicine function measurement is about a few dozen dollars, the imaging examination is mostly a few hundred dollars, there are also several thousand dollars or even about ten thousand dollars, the intuitive feeling is indeed very expensive ah. The price depends mainly on the cost. Whether such an expensive test is worth it or not depends on how useful it is in the overall diagnostic and treatment process and whether it ultimately saves or costs the patient money. For example, whole body bone imaging in nuclear medicine is a very sensitive method for early detection of tumor bone metastasis, and it costs several hundred dollars to do one. However, it can detect bone metastasis at an early stage and can avoid unnecessary surgeries. The expense of reducing unnecessary surgery is far greater than the expense of doing bone imaging. Not to mention the surgery that should not be done, the damage caused to the patient is immeasurable. Another example is that many patients with coronary artery disease will avoid unnecessary catheter interventions after having nuclear medicine myocardial perfusion imaging done. Nuclear medicine exams cost about $2,000, and catheter interventions are often tens of thousands of dollars. And reducing the risk of restenosis due to catheterization and the occurrence of restenosis after the procedure is even more critical to the patient’s prognosis. Therefore, the cost of the test cannot be measured simply by the cost of the test, but usually by the “value for money”. Instead of saying whether the test is expensive or not, we should consider whether it is worth it. Many developed countries attach great importance to the role of nuclear medicine examinations in treatment decisions, and many important treatments, such as oncology surgery and coronary heart disease stenting, require nuclear medicine examinations prior to surgery, otherwise these treatments are considered unreasonable and insurance companies will not pay for them.
