What are the early detection methods for liver cancer? Introduction to early detection methods for liver cancer

Liver cancer is a malignant tumor. Early detection of liver cancer can be timely discovered, and of course, patients can receive timely treatment. Therefore, we should treat early detection of liver cancer rationally. So, what are the early detection methods for liver cancer?

MRI

Magnetic resonance imaging is a method that has developed rapidly in recent years. In the past, MRI was not as ideal as CT examination. Now, with the continuous development of MRI technology, the scanning time is getting faster and faster, and the resolution is getting higher and higher. It can also make a relatively accurate judgment for some small lesions in the liver. Now MRI also plays a very important role in the early detection of liver cancer.

Alpha-fetoprotein test

To see if there are tumor markers, alpha-fetoprotein has a certain sensitivity in detecting liver cancer, but we have also found clinically that the alpha-fetoprotein of some patients with early liver cancer is not necessarily high. The alpha-fetoprotein of patients with early liver cancer can be high, but patients with low alpha-fetoprotein cannot completely rule out the possibility of liver cancer.

CT

CT scan for liver cancer is a very important method and is done quite frequently across the country.

Ultrasonography

Ultrasound examination is also a means of diagnosing early liver cancer. The characteristics of ultrasound are that it is relatively easy to operate, the cost is relatively low, and the detection rate of liver lesions is also relatively high.

Isotope examination

Currently, there is an advanced examination instrument, pET-CT, which can make a more accurate diagnosis of early liver cancer. pET-CT is not as sensitive to liver cancer itself as the previous ones, but it is very sensitive to metastatic cancer.

Angiography

Although the accuracy of early diagnosis of liver cancer is very high, this method is invasive. First, an incision must be made in the femoral artery, and a tube must be inserted into the femoral artery and all the way to the hepatic artery to visualize the tumor blood vessels. Hepatic artery angiography is not the first choice because it is invasive. Now it is more used as a treatment, which is what we usually call interventional treatment. It is performed through the hepatic artery lesion, and anti-cancer drugs are directly injected into the tumor blood vessels through a catheter to achieve the therapeutic effect.
