Sometimes, when the diagnosis of a disease is still not clear through various examination methods, the diagnosis can be clarified through specific treatment, and this method is to make a differential diagnosis through treatment. For example, if a patient has a cough, coughs blood, and has chest pain, and has a CT examination, and there is a shadow on the film, some professors think it is tuberculosis, and some professors think it is lung cancer. You can first do anti-tuberculosis treatment without surgery. If it is tuberculosis, the effect is often seen in a month, if it is cancer, the effect is often not good. The same is true for the diagnosis of hepatic hemangioma and liver cancer, when the shadow on the CT film is less than 4 centimeters, it often affects the correctness of the diagnosis, and the smaller it is, the more difficult it is. Therefore, whether it is CT, MRI, or ultrasound doctors, when they issue the examination report, they say it is more likely to be hepatic hemangioma, they do not say it must be hepatic hemangioma, and let continue to observe, they all leave some leeway and do not say absolutely, so as not to be passive This has affected the timely treatment of some patients. Like tuberculosis, hepatic hemangioma and hepatocellular carcinoma can be diagnosed through treatment. With ultrasound-guided, minimally invasive interventional treatment, most patients, after only 1-2 treatments and one month, can put an end to this heartbreak.
