The pancreas is a very important digestive and endocrine organ in the human body, and its disease incidence rate is increasing year by year. The diagnosis of pancreatic diseases has always been a difficult point in the medical field, and traditional imaging techniques such as X-ray and CT have problems with radiation and high costs. In recent years, with the development of medical technology, medical ultrasound scanners have been widely used in the diagnosis of pancreatic diseases, providing new diagnostic methods for clinical practice. This article will explore the new progress of medical ultrasound scanners in the diagnosis of pancreatic diseases.

1、 The working principle of medical ultrasonic scanner

Medical ultrasound scanners use high-frequency sound waves (usually between 100kHz and 20MHz) to scan specific parts of the human body to obtain high-resolution images. When ultrasonic signals propagate in human tissues, they will reflect and refract at the interfaces of different tissues, resulting in echo signals. These echo signals are received by the receiver and converted into electrical signals, which are further processed to form images.

2、 Application of ultrasound scanner in the diagnosis of pancreatic diseases

Pancreatic Tumor

Pancreatic tumors are common pancreatic diseases, and early diagnosis and treatment are of great significance for prognosis. Ultrasound scanners can clearly display the shape, size, location, and relationship with surrounding tissues of pancreatic tumors, which helps in the qualitative diagnosis of tumors. At the same time, ultrasound scanning can also detect lymph node metastasis and liver metastasis, providing a basis for the selection of treatment plans.

acute pancreatitis

Acute pancreatitis is one of the common acute abdominal diseases, and timely diagnosis and treatment are crucial for prognosis. Ultrasound scanners can display the morphology and blood flow of the pancreas in real-time and intuitively, which is helpful for the early diagnosis of acute pancreatitis. In addition, ultrasound scanning can also detect complications such as pancreatic abscess and abdominal fluid accumulation, providing guidance for treatment.

chronic pancreatitis

Chronic pancreatitis is the chronic stage of pancreatitis, often leading to a decrease in pancreatic function. Ultrasound scanners can display morphological changes in the pancreas, such as pancreatic atrophy and calcification, which is helpful in the diagnosis of chronic pancreatitis. Meanwhile, ultrasound scanning can also detect complications such as pancreatic duct stones and pancreatic cysts, further assessing the severity of the condition.

Insulinoma

Insulinoma is a rare pancreatic endocrine tumor that often causes hypoglycemic symptoms. Ultrasound scanners can clearly display the shape and location of insulinoma, which helps to diagnose insulinoma and provide a basis for surgical resection.

3、 Application of ultrasound scanner in pancreatic disease tracking

Evaluation of therapeutic effects

The treatment methods vary for different types of pancreatic diseases. Ultrasound scanners can evaluate treatment effectiveness and help doctors adjust treatment plans. For example, by observing the size changes of tumors through regular ultrasound scans, the effectiveness of treatments such as surgery, radiotherapy, and chemotherapy can be judged; By observing changes in pancreatic blood flow, the effectiveness of treatment measures such as anti-inflammatory and improving microcirculation can be determined.

Disease monitoring and prevention

Pancreatic disease patients need long-term follow-up and monitoring to monitor changes in their condition and prevent complications. Ultrasound scanners can serve as a convenient monitoring tool to regularly evaluate the health status of the pancreas. For example, by observing the changes in pancreatic morphology through regular ultrasound scans, the development trend of the disease can be determined; By observing changes in pancreatic blood flow, the risk of acute pancreatitis can be predicted.

4、 The limitations of ultrasonic scanners and their overcoming methods

Operator's technical level

The operation of ultrasonic scanners requires professional medical knowledge and skills, and the operator's technical level directly affects image quality and diagnostic accuracy. In order to improve diagnostic accuracy, it is necessary to strengthen the technical training and experience accumulation of operators.

Obesity and gas interference

Obesity and gastrointestinal gas are one of the main factors affecting the quality of ultrasound scanning. The adipose tissue of obese individuals has a attenuation effect on ultrasound signals, reducing image quality; Gas in the gastrointestinal tract can also interfere with the propagation of ultrasound signals, leading to blurred images. Therefore, before ultrasound scanning, it is necessary to prepare the gastrointestinal tract, such as fasting, taking laxatives, etc., to reduce gas interference.

Equipment costs and maintenance

The high equipment and maintenance costs of ultrasound scanners limit their widespread clinical application. In order to reduce costs, optimizing equipment design and reducing maintenance costs can be used to reduce costs and improve equipment accessibility.

Medical ultrasound scanners have played an important role in the diagnosis and tracking of pancreatic diseases, providing new diagnostic tools for clinical practice. However, there are still some limitations in the practical application of ultrasonic scanners, such as the operator's technical level, obesity, and gas interference. In order to further improve the accuracy and accessibility of ultrasound scanning in the diagnosis of pancreatic diseases, it is necessary to strengthen technical training for operators, optimize equipment design, and reduce maintenance costs. In the future, with the continuous progress and innovation of medical technology, it is believed that the application of ultrasound scanning in the diagnosis of pancreatic diseases will be more extensive and in-depth
