Ultrasonic scanners have been widely used in the medical field, and also play an important role in the diagnosis of gastric mucosa tumors. This article will introduce the application of ultrasonic scanner in the diagnosis of gastric mucosa tumors from the following aspects.

1、 Definition and classification of gastric mucosa tumors

Gastric mucosa tumor refers to a type of tumor that occurs in the inner submucosa layer of the gastric wall, and its diameter is usually less than 2 cm. According to the pathological characteristics and clinical manifestations, gastric mucosa tumors can be divided into benign and malignant types. Among them, benign gastric mucosa tumors include leiomyoma, neurogenic tumor, etc; Malignant gastric mucosa tumors include gastric stromal tumors, gastrointestinal stromal tumors, etc.

2、 Application of ultrasonic scanner in the diagnosis of gastric mucosa tumors

1. Detection position: The ultrasonic scanner can scan the gastric mucosa tumor comprehensively through the probe at different angles. In addition, the probe of the ultrasonic scanner can easily enter the stomach cavity to detect gastric mucosa tumors without damage.

2. Recognition characteristics: The ultrasonic scanner can show different characteristics of benign and malignant gastric mucosa tumors through scanning in different modes. For example, benign submucosal tumors of the gastric mucosa are usually round or oval with clear boundaries; Malignant gastric mucosa tumors often have irregular shapes and fuzzy edges.

3. Measurement of size: The ultrasonic scanner can accurately measure the size, depth, shape and other parameters of the gastric mucosa tumor, providing a reference for doctors to formulate treatment plans.

4. Evaluation of surrounding tissue: The ultrasonic scanner can also evaluate the tissue around the gastric mucosa tumor, including the level of gastric wall, blood flow, etc., which is helpful for doctors to determine the treatment plan and prognosis.

3、 The advantages of ultrasonic scanner in the diagnosis of gastric mucosa tumors

1. Non invasive: Using an ultrasound scanner for detection does not require invasive procedures such as puncture or surgery, and there is no harm to the patient.

2. High accuracy: ultrasonic scanner can quickly and accurately diagnose gastric mucosa tumors, effectively avoiding misdiagnosis and missed diagnosis.

3. Strong repeatability: Due to the simple and easy operation of ultrasonic scanners, the results of multiple inspections have high consistency and repeatability.
