ABSTRACT
@#TNM（tumor node metastasis）classification is a common way to evaluate the prognosis of patients with oral cancer; however, many years of application have proven this method to be confined merely in clinical and pathological data and it cannot be adapted to the development of modern medicine. Deep learning (DL) has been widely used in various aspects of human life, has advantages for conducting efficient and intelligent searches and can explore and analyze substantial medical information well. Additionally, the application of DL to medical practice is quickly increasing. In the field of oral cancer prognosis, DL can efficiently process and analyze the pathological, radiographic and molecular data of oral cancer patients represented by lymphocytes, gray level cooccurrence matrix (GLCM) and gene maps and make accurate prognostic judgments accordingly. By assisting physicians in optimizing treatment plans, DL can effectively improve patients’ survival. Although DL lacks sufficient data and practical clinical application in prognostic studies, it has shown good clinical application prospects.
ABSTRACT
@#With the development of social economy and medicine, degenerative heart valve disease has become the major part in heart valve disease. Calcific aortic valve disease (CAVD) is one of the most representative manifestations of degenerative valvular disease. Aortic valve calcification (AVC) has been found to be a strong predictor of major cardiovascular events, which makes it necessary to identify an effective way to evaluate the degree of AVC. Numerous methods of quantitative assessment of AVC have been reported. Here, we discuss these methods from the aspects of pathology and imageology.
ABSTRACT
Background Orbital cavernous hemangiomas (OCH) is a common benign orbital tumor in adult,and accurate localization and diagnosis before operation supports the significant premise for surgical safety and success of tumor extraction.Objective This study was to research the clinical characteristics,preoperative diagnosis,the selection for different surgical approaches,therapeutic effectiveness and complication prevention of OCH.Methods The clinical data of 117 eyes of 117 patients with OCH who received surgery were retrospectively analyzed.The patients received surgery in Henan Eye Institute,Henan Eye Hospital from January 2011 to December 2014 and followed-up for 3 months to 5 years.The visual acuity,exophthalmos,ocular movement,orbital A/B ultrasound,color Doppler image,CT and MRI were examined before and after surgery.Results The primary clinical manifestations of OCH were gradual exophthalmos and impaired vision.The accordance rate of preoperative diagnosis and pathological diagnosis was 100％ in the group of patients.The surgical approachs included conjunctival approach in 52.14％ (61/117),lateral orbitectomy in 30.77％ (36/117),anterior approach in 16.24％ (19/117) and lateral combined with medial approach in 0.85％ (1/117).At the end of followed-up,visual acuity was significantly improved in 30.77％ (36/117),declined in 8.55％ (10/117) and unchanged in 60.68％ (71/117).Temporary complications after surgery were pupil dilatation in 14.53％ (17/117),emorrhoea in 1.71％ (2/117),ocular motility disorders in 16.24％ (19/117) and ptosis in 4.27％ (5/117).The permanent complications after operation were pupil dilatation in 2.56％ (3/117),visual loss in 0.85％ (1/117) and permanent abduction imitation in 0.85％ (1/117).Conclusions Accurate qualitative and site-specific diagnosis and correct choice of surgeries for OCH depend on clinical and iconographical examinations.Suitable surgical approach and operative skill are helpful to the therapeutic outcome and safety of OCH.
ABSTRACT
The application of PACS in the teaching is an hot focus in current medical imaging teaching reformation , and the establishing of independent medical imaging teaching case database based on PACS-HIS is the first and key of construction of teaching PACS(T-PACS). Several key steps of designing and constructing database will be discussed in this paper. ①To customize case classifi-cation and code according to the medical imageology textbook. ②To construct the independent case database meeting the teaching needs. ③To establish a set of mechanism of collection teaching cases based on real time in clinical PACS environment. ④development of experiment teaching application etc.
ABSTRACT
According to the characteristics of pediatric resident training, the situation in clinic practice of medical imageology are analyzed and the major problems are pointed out.This article empha sizes significance of standardized resident training of medical imageology, presents detailed requirement which the residents must meet and aims to improve the training effect by the solutions summarized after years of experience.
ABSTRACT
With the increasingly strengthening of economic globalization and higher education internationalization,medical imageology as an important intersecting science in life sciences has more and more international communion and cooperation.In China many hospitals and medical colleges require large quantities of medical imageology professionals,and it is very necessary and important to develop the bilingual education in medical imageology,though a series of problems appear in the process.
ABSTRACT
In order to further the progress of the quality of practice teaching in medical imageology,different teaching methods in practice teaching should be taken into account such as the features of teaching,knowledge structure and learning ability in medi- cal imageology.
ABSTRACT
To study the mode of practice teaching in medical imageology,140 students from pediatric department and medical imageology department were surveyed.The results showed that the problem of out-of-date teaching mode existed in both departments,and the differences between pediatric and medical imageology department were that the latter have a more intensive need for more disease entity and such advanced contents as CT and MRI.In this paper,the causes of the problems mentioned above were analyzed and related strategies were put forward.
ABSTRACT
According to the characteristics of pediatric specialty,the teaching content of medical imageology was adjusted and optimized by blending with pediatric imaging.The purpose of the present study was to elevate the teaching efficiency and to cultivate medical talents with characteristics of pediatric specialty.
