Enhanced MRI, or MRI-enhanced scanning, can initially diagnose the benign or malignant nature of liver tumors, but the gold standard for tumor diagnosis is tumor pathology testing. An MRI-enhanced scan is a test in which a contrast agent is injected into the patient’s blood vessels before the MRI scan is performed. When patients with liver tumors undergo this examination, the contrast agent will follow the blood into the tumor and the blood vessels of the surrounding tissues. Since the blood vessels of malignant tumors are more abundant and continue to undergo malignant proliferation, at this time, there is a higher content of contrast agent in the blood vessels, and the results of the examination often indicate that the signal of the blood flow is obviously strengthened. Through this result, it can be initially determined whether the patient’s liver tumor is benign or malignant. At present, the gold standard for diagnosing benign and malignant tumors in clinical practice is the result of pathological examination. If the tumor blood flow signal is obviously enhanced after MRI-enhanced scanning of liver tumor patients, and the result of liver puncture biopsy is positive, then it can be diagnosed as malignant tumor. To sum up, the results of MRI enhanced scan are mainly used for preliminary judgment of the nature of liver tumor, and the specific diagnosis should be combined with medical history, laboratory examination, pathological biopsy and other comprehensive judgment.
