What to check for gallbladder cancer

For every disease, only through instrument examination can we make a correct judgment on the location and size of the disease, especially for gallbladder cancer, examination is essential, so we should strengthen the learning of this inspection knowledge. The article below is about the common examination methods for gallbladder cancer.

There are many patients with gallbladder cancer. At present, many people have lost their precious lives due to the disease, so we cannot ignore the harmfulness of the disease. Diagnosis is the first step in treating the disease. If everyone can pay more attention to the details of their lives, this disease can also be avoided.

1. CT scan: CT scan is not as good as ultrasound for the diagnosis of early gallbladder cancer. However, for patients who have been found to be highly suspected of gallbladder cancer by ultrasound, enhanced CT examination is necessary. The CT imaging changes of gallbladder cancer can be divided into three types: ① Wall thickness type: limited or diffuse irregular thickening of the gallbladder wall. ② Nodular type: papillary nodules protrude from the gallbladder wall into the cavity. ③ Solid type: due to the extensive infiltration and thickening of the gallbladder wall by the tumor and the filling of the intracavitary cancer mass, a substantial mass is formed. In enhanced scanning, it can generally be seen that the lesion tissue has a rich blood supply. If the tumor invades the liver or has related lymph node metastasis, it can often be displayed under CT images. This is a common examination method for gallbladder cancer.

2. Magnetic resonance imaging (MRI): MRI is generally not the first choice or necessary examination item for gallbladder cancer. It can only be considered when it is necessary to determine whether the lesion involves the liver or when the patient has obstructive jaundice. The accuracy of this gallbladder cancer examination method is similar to CT, but it has the advantage of no radiation damage and can be repeated many times.

3. PET-CT: As a relatively qualitative examination item, under the premise of excluding acute cholecystitis, this examination of gallbladder cancer can help to make a qualitative diagnosis of gallbladder space-occupying lesions and help to determine whether there are lesions outside the gallbladder. However, it is expensive and prone to false positive results when combined with acute cholecystitis, so it is generally not used as a routine examination.

4. Ultrasound examination: B-ultrasound examination is simple, non-destructive and can be used repeatedly. Its diagnostic accuracy rate is over 90%, making it the preferred method for gallbladder cancer examination. With the continuous upgrading of instruments, it is now possible to not only clearly observe the size of gallbladder lesions, but also to help determine whether cancer has occurred by observing the blood flow of the lesion tissue. It can also be used to observe whether there is obvious lymph node metastasis and whether the liver is involved. Experienced examiners can even determine which layer of the gallbladder is affected by the lesion.

The experts have shared a series of knowledge about common examination methods for gallbladder cancer. We must take this disease seriously in our minds. If we feel unwell, we should get checked as soon as possible and never miss the best time for treatment. In addition, we should maintain a good mentality during the treatment.
