What is rotation CT after esophagus cancer operation

summary

My grandfather always can't eat, as long as he eats, his esophagus is very painful. Two days ago, we went to the hospital to check that my grandfather had esophageal cancer. We had to have an operation, otherwise it might be life-threatening. Next, I'd like to talk about rotating CT after esophageal cancer surgery.

What is rotation CT after esophagus cancer operation

First, operation is the first choice for the treatment of esophageal cancer. If the general condition is good, the cardiopulmonary function reserve is good, and there is no obvious sign of distant metastasis, surgical treatment can be considered. In general, cervical cancer length < 3cm, upper thoracic cancer length < 4cm, lower thoracic cancer length < 5cm are more likely to be resected. With the increase of scanning speed per unit time, the motion artifacts are reduced.

Second: it can continuously rotate scanning, and the patient's bed also moves forward and backward at a certain speed, which not only increases the scanning speed several times, but also this spiral scanning is no longer to collect data on a certain level of the human body, but also a section of volume spiral around the human body, which is called volume scanning. It is not only fast, but also obtains three-dimensional information, which increases the confidence Because of the content and flexibility of information processing, it can get real three-dimensional reconstruction image and make three-dimensional vascular imaging possible.

Third: however, there are also cases where the tumor is not too large but has been closely adhered to the main organs, such as aorta, trachea, etc. The whole organ or a part of a breath holding volume scan, will not produce the omission of lesions. The utilization rate of contrast agent is improved. It is reported that the dosage of contrast agent can be saved by 50%. It can be reconstructed arbitrarily and retrospectively without the restriction of the size of the interval and the number of reconstructions. Volume scanning improves the quality of multi-directional and three-dimensional reconstruction image.

matters needing attention

Many patients with esophageal cancer should be treated by surgery. After all, this is the best treatment with the least impact on the patient's body. Generally speaking, after esophageal cancer surgery, do rotary CT can be very good to see the recovery of patients, there is no other lesions.
