With the development of imaging theoretical knowledge and imaging technology for many years, medical imaging has become an independent discipline with both connections and differences with clinical medicine. The following is what I arranged for you for your reference.

Fan: experimental teaching reform of medical imaging technology

abstract

Medical imaging technology is an important basic subject in the medical field, and it is also a very practical subject. However, due to the limitation of educational conditions, the teaching methods of medical imaging technology in many colleges and universities are still in a simple theoretical teaching mode, which is not comprehensive enough to cultivate students' practical ability. Based on this, our main research focus in this paper is the reform of medical imaging technology, to understand the main problems existing in the current teaching mode, and to put forward specific solutions to effectively improve the teaching effect of medical imaging technology.

Medical imaging technology; Experimental teaching; Reform and innovation; Analytical research

With the rapid development of society, people's requirements for medical technology are getting higher and higher. As an important subject in the field of modern medicine, image diagnosis technology must be constantly updated and improved with the development of society. In this harsh reality, we put forward higher standards for the experimental teaching mode of medical imaging technology. The teaching mode must break the traditional conventional mode and develop in a more scientific, digital and informational direction.

First, the particularity of medical imaging experiment teaching

Medical imaging technology is a basic medical subject, which plays an important role in the medical field and plays a decisive role in students' better adaptation to post requirements in the future. Generally speaking, the particularity of experimental teaching of medical imaging is mainly manifested in the following aspects:

1. It is practical.

He is a very practical subject. Simple theoretical study can not make students fully grasp the technical requirements. It is necessary to combine theoretical knowledge with practical operation through effective experimental courses to improve their practical ability and clinical work ability.

2. The popularization and application of new technologies are rapid and extensive.

Medical imaging technology is a new subject in medicine, which develops very rapidly and has a broad research field and space. Whenever new technical means are applied to clinical medical treatment, experimental teaching must keep up with its pace and avoid the phenomenon of being out of touch with clinic.

3. Have more contact with other disciplines.

Medical imaging technology is an important basis for the diagnosis of many other clinical diseases, and it has many connections with other disciplines. Therefore, the experimental teaching of medical imaging should not only let students learn operation skills, but also let students learn how to deal with various diseases.

Second, the main problems existing in the current experimental teaching mode of medical imaging technology

Medical imaging technology has its unique particularity, so the research on it should also be targeted. However, as far as the current teaching practice in medical colleges is concerned, there are still many shortcomings in the teaching mode of this subject in many schools, which can be summarized as follows:

1. The experimental syllabus and teaching materials are relatively backward.

In recent years, with the rapid development of medical imaging technology, many technologies and equipment have undergone tremendous changes. However, at present, there are no new technologies and theories in the books used in domestic universities, and there are few experimental explanations of medical imaging technology. The new technology involved is very narrow, and even some textbooks still use outdated technical textbooks, which has a great negative impact on students' learning.

2. The experimental class is relatively short.

Medical imaging technology is a practical subject, and experimental teaching should be mainly used for his study. However, due to the influence of traditional teaching mode, many colleges and universities adopt pure theoretical teaching mode for this course at present, and the experimental teaching hours are relatively few, which makes many students learn theoretical knowledge, but they can't actually apply it to practice, resulting in poor post adaptability.

3. The experimental teaching method is single and backward.

In the past, our experimental course of medical imaging technology was mainly conducted in the laboratory. However, due to the limited teaching conditions in the laboratory, there is not enough experimental content to be exposed to. Generally, only some basic experimental practice can be carried out, and the large-scale digital equipment commonly used in clinical medicine is not well understood.

Third, the measures of experimental teaching reform of medical imaging technology

With the development and progress of society, people have higher and higher requirements for medical level. As an important means of medical diagnosis, medical imaging technology has been widely used in the medical field. Generally speaking, according to the current teaching practice, the measures of experimental teaching reform of medical imaging technology can be mainly divided into the following points:

1. Diversified learning and practice activities, focusing on learning medical imaging technology in training.

The study of medical imaging technology is not purely theoretical, and experimental teaching also plays a very important role. Therefore, one of the directions of teaching reform in the future is to strengthen practical teaching reform, continuously introduce advanced device technology, enrich educational resources, and enable students to know the latest technical means in time, thus effectively improving practical operation skills.

2. Pay attention to the introduction of talents and strengthen the construction of experimental teachers.

The lack of teachers' ability is one of the main reasons for the poor effect of image teaching at present. It turns out that an experimental teaching needs to bring a class of students, which greatly increases the workload of teachers and weakens the continuous guidance to students. By introducing and cultivating talents, strengthening the construction of experimental teachers and increasing the actual number of teachers, the teaching environment can be greatly improved and students can fully enjoy the teacher resources.

3. Improve the experimental teaching materials and databases.

With a series of reform and development, we should constantly incorporate the latest medical imaging technology into teaching materials according to the reality of technical development, so that students can know the current technical forms in time and better master the technical ability. At the same time, we should gradually improve the database to ensure that every student has sufficient information sources.

To sum up, the experimental teaching of medical imaging has its unique particularity, which determines that it needs continuous development. According to the actual teaching situation of medical colleges and universities, combined with the actual clinical needs and the new progress of medical imaging technology, the experimental teaching reform is continuously carried out to lay a solid foundation for students to embark on clinical work.

Fan: the application of clinical medical imaging in urinary calculi

Urinary calculi are one of the most common diseases in clinical urology, including kidney calculi's disease, ureteral calculi, bladder calculi and urethral calculi. 84 patients with urinary calculi were selected as the research object. The purpose of this study is to use infrared ray as the basic standard to measure the composition of urinary stones, and to explore the diagnostic role of CT value in the composition of stones. The research results are reported as follows.

1 data and methods

1. 1 general information

84 patients with urinary calculi in this group meet the relevant diagnostic criteria of WHO. Among them, there were 55 males and 29 females; The age ranged from August to 82 years, with an average age of 40.2 6.7 years. Among them, there were 54 cases of calculi, 9 cases of ureteral calculi1and 9 cases of vesicoureteral calculi 1 1. There were 54 cases of single stone, 20 cases of multiple stones and staghorn stones 10 cases. The largest diameter of kidney calculi is 8 cm, and the largest diameter of ureteral calculi is 3 cm. Among the clinical symptoms, 49 cases (60.59%) complained of renal colic, 65,438+065,438+0 cases (65,438+065,438+0.8%) complained of gross hematuria or cryptouria, and 65,438+08 cases (22.6%).

Normal detection mode of 1.2CT scanning

Use American GECardiacLightSpeedVCT63 line scanner and Toshiba 15 line scanner. Among them, GECardiacLightSpeedVCT63 line scanner and Toshiba 15 line scanner made in the United States all set the following parameters, that is, the scanning voltage is between 90~ 135KV, and the scanning layer thickness is 3 or 2.7mm, so as to complete the omni-directional scanning of the urinary system. Patients no longer need to complete intestinal preparation before completing the test, but it may cause great interference in exploring the consequences of scanning food or gas in the intestine. Without changing the medical safety conditions, patients are advised to fast for more than 7 hours. Before scanning, patients should be told to drink 500 ml ~ 1 100 ml clean water. 1 hour or so, patients should consciously feel that urine is full of bladder before scanning. When scanning, ask the patient to hold his head in his hands, lie on his back and take a deep breath. The scanning range was from the upper part of the kidney to the lower part of the pubic symphysis for 4 minutes.

Two results

The situation of 84 patients with stones we investigated is roughly as follows: the equilibrium CT values of 84 patients with stones are: ammonium urate 230.37HU, anhydrous uric acid 243.28HU, apatite carbonate 860.6 1HU, calcium oxalate monohydrate 639.03HU, calcium oxalate dihydrate 673.6 1HU, and uric acid dihydrate 279.57HU.

3 discussion

With regard to the treatment of urinary calculi, in recent years, with the rapid progress of surgical props and surgical techniques in urology, the development of laparoscopic techniques, percutaneous nephrolithotomy (PCNL) and various endoscopic instruments, the treatment level of urinary calculi has been significantly improved, and more than 80% of them are no longer treated by traditional open surgery [2-3]. However, despite this, the legacy and repetition of stones after surgical treatment also brought great pain to patients. Therefore, it is of great significance to explore the pathogenic factors of urinary calculi and guide the preventive measures of calculi. Urinary calculi not only have a high incidence rate, but also have a high recurrence rate, which is one of the difficulties that plague clinicians. The progress of stone processing technology and facilities is only the result of overall factors. However, the risk factors of stones caused by patients after discharge have not been improved. Recurrent calculi refer to urinary calculi that have been removed by self-drainage, intracavitary surgery or extracorporeal shock wave lithotripsy, and then made again with the intervention of pathological factors. When patients go to the hospital for follow-up [5], the study of urine metabolism can bring reference for treatment. The concentration of calcium, magnesium, phosphorus, sodium, uric acid and creatinine, the concentration of oxalic acid and citric acid, pH value and total value must be determined in urine samples, which is helpful to find out the internal factors inducing urinary calculi as soon as possible. The concentrations of calcium, magnesium, phosphorus, sodium, uric acid and creatinine in serum should be determined when selecting blood samples. Combined with the results of this study, it can be concluded that the accuracy of CT value in diagnosing apatite carbonate and calcium oxalate monohydrate stones is higher than others, and the accuracy in judging other stones is not clear. If we need to improve the accuracy of judgment in clinic, we must refer to other methods, such as urine metabolism discussion, which can improve the accuracy of judgment.
