Medical ultrasound scanner is a diagnostic tool widely used in the medical field, which can generate images of the internal structure of the human body by sending high-frequency sound waves and receiving echoes. These images have extremely high value for the diagnosis and treatment of oncology. In oncology, medical ultrasound scanners can be used to detect tumors, evaluate the nature and status of tumors, and monitor treatment outcomes. This article will provide a detailed introduction to the application of medical ultrasound scanners in oncology.

1、 Detection and diagnosis of tumors

Local lymph node detection: Local lymph nodes are common metastatic sites of tumors, and medical ultrasound scanners can detect whether lymph nodes are enlarged and determine their properties. For breast cancer, esophageal cancer, lung cancer and other tumors, ultrasound scanning is of great significance for the diagnosis of lymph node metastasis.

Organ tumor detection: Medical ultrasound scanners can detect tumors in organs such as the liver, kidneys, ovaries, and provide detailed descriptions of their size, morphology, echo, and other information, providing a basis for further treatment.

Peripheral tissue tumor detection: Medical ultrasound scanners can also detect and diagnose tumors in peripheral tissues such as muscle and fat, providing assistance in developing treatment plans.

2、 Evaluation and monitoring of tumor treatment

Evaluation of radiotherapy and chemotherapy effects: During the radiotherapy and chemotherapy process, medical ultrasound scanners can monitor the size changes of tumors in real-time, thereby evaluating the treatment effect. For effective treatment, the tumor size will gradually decrease; For ineffective treatment, it is necessary to adjust the treatment plan.

Surgical navigation: During surgery, medical ultrasound scanners can provide real-time navigation to help doctors accurately locate tumors and avoid damage to surrounding tissues. Especially in minimally invasive surgery, medical ultrasound scanners play an important role.

Intraoperative monitoring: During the surgical process, medical ultrasound scanners can monitor the tumor resection process, prevent the resection range from being too large or too small, and ensure the thoroughness and safety of the surgery.

3、 Ultrasound guided puncture biopsy

In oncology, sometimes it is necessary to obtain pathological information of tumors through puncture biopsy to determine their nature and treatment plan. Medical ultrasound scanners can guide doctors to perform precise puncture biopsies, avoiding important blood vessels and nerves, and improving puncture accuracy and safety. Through puncture biopsy, cytological and molecular biological information of tumors can be obtained, providing a basis for formulating personalized treatment plans.

4、 Efficacy evaluation and prognosis judgment

Efficacy evaluation: For tumor patients who have already received surgery, radiotherapy, and chemotherapy, medical ultrasound scanners can regularly evaluate their efficacy and monitor changes in the tumor. If the tumor relapses or grows again, ultrasound scanning can timely detect and guide the adjustment of treatment plans.

Prognostic assessment: Medical ultrasound scanners can help evaluate the prognosis of patients based on factors such as the malignancy, size, and lymph node metastasis of the tumor. For patients with poor prognosis, more proactive treatment plans should be developed and follow-up observation should be strengthened.

5、 Molecular Biology Research

With the increasingly widespread application of molecular biology technology in oncology, medical ultrasound scanners have also played a certain role in molecular biology research. For example, studying the relationship between the uptake ability of ultrasound contrast agents by tumor cells and their molecular biological characteristics provides ideas for developing new treatment strategies; Using ultrasound scanners to detect the expression products during gene therapy and evaluate the therapeutic effect.

In summary, medical ultrasound scanners have broad application value in oncology. It can not only be used for tumor detection and diagnosis, but also for evaluating treatment effectiveness, monitoring changes in the condition, guiding puncture biopsy, and so on. With the continuous development of technology, the performance of medical ultrasound scanners will continue to improve, and their applications in oncology will also be more extensive and in-depth. In the future, we look forward to more research achievements and application breakthroughs in medical ultrasound scanners in oncology.
