Application Advances of Contrast-enhanced Ultrasound in Clinical Diagnosis and Treatment

Because the affected parts of some tumors and diseases are generally hidden, some are deeper, and the tissue structure is more complex and diverse, misdiagnosis and missed diagnosis are very easy to occur in the process of clinical diagnosis. In addition, the development of various diseases and tumors is closely related to the quality of life and prognosis of patients. Therefore, the diagnosis and treatment of diseases and monitoring after treatment are particularly important for patients. Ultrasound is easy to operate, non-invasive, and can be observed in real time. Ultrasound is the most used Frequent imaging diagnostic tools. In recent years, contrast-enhanced ultrasound (CEUS), as a newly developed imaging technology, has made important progress in ultrasound examination. In particular, the second-generation microbubble (MB) contrast agent in contrast-enhanced ultrasound (CEUS) has been widely used in clinical practice. It can observe the whole process of organ and tumor microcirculation blood perfusion in real time and continuously, not only The morphological characteristics of the lesion can also provide the blood flow characteristics of the lesion, which improves the ability of the ultrasonic diagnostic instrument to display the blood flow in the lesion. Due to its non-invasiveness, real-time and safety, contrast-enhanced ultrasound technology provides safe, effective and valuable diagnostic and treatment options for ophthalmology, liver, gastrointestinal tract, heart, pediatrics and other fields. This article briefly reviews the origin and development of contrast agent ultrasound, basic principles, safety, the application of contrast-enhanced ultrasound in clinical diagnosis and treatment, and the advantages and disadvantages of contrast-enhanced ultrasound, and discusses its future development and limitations for pre-clinical surgery The qualitative diagnosis, selection of surgical methods and prognostic judgment and evaluation provide more accurate and comprehensive information in order to better serve and treat clinical diagnosis.
