What does rectal cancer ultrasound examination mean

With the continuous development of life, people's living standards have been greatly improved. Similarly, medical technology has also been greatly improved. For many diseases, related treatment and diagnosis methods have also brought great benefits to patients. This is also true for patients with rectal cancer. What is rectal cancer ultrasound examination? It is a way to check for rectal cancer, and there are many other methods.

Ultrasound imaging is a new diagnostic method for detecting the invasion of rectal cancer and the degree of tumor infiltration into the rectal wall. It has been used in clinical practice since 1983. It can accurately diagnose the location and size of the tumor invasion.
Magnetic resonance imaging: Some researchers claim that magnetic resonance imaging (MRI) is more meaningful than CT for the external invasion of rectal cancer. However, there are still many technical issues that need to be improved, and the understanding of the images provided by MRI needs to be further deepened. At the same time, compared with intracavitary ultrasound imaging, the high cost of MRI examination is also an obstacle to its widespread application.
CT diagnosis
CT cannot be used as an early diagnosis method, but CT is important for the staging of colon cancer, especially for patients who are estimated not to be able to undergo direct surgery but may be surgically removed after external radiation or local intracavitary radiotherapy. CT is of great significance for the surgical estimation of advanced rectal cancer and recurrent rectal cancer, and can directly observe the invasion of tumors into pelvic muscles (levator ani, obturator internus, coccygeus, piriformis, gluteal muscles), bladder and prostate.
