The Impact

Despite the impact of osteoarthritis (OA) on patients and the health service, OA remains an elusive condition to define and treat. Traditionally, OA has been diagnosed using radiographs and more recently magnetic resonance imaging; however, the last 20 years of research have changed our thinking about the disease and its treatment. We know today that OA takes up to 10–15 years to develop, has a range of risk factors, and that there is a considerable discordance between symptoms and structural signs, such that new classifications and definitions are moving away from structural criteria to combined structure and pain definitions. This chapter reviews the definition and classification of OA and its prevalence, incidence, and natural history.

Toast Classification

Objective: To analyze the relationship between TOAST classification of cerebral infarction after cerebral ischemia and traditional risk factors by high-resolution NMR. Methods: A total of 942 patients with cerebral infarction who were hospitalized in our hospital from January 2012 to October 2019 were enrolled. After performing brain magnetic resonance examination, they were classified according to magnetic resonance imaging, and the patient’s age was recorded. Clinical data such as gender and disease history, and routine examination of diabetes, blood lipids, etc., according to the results of the test, TOAST classification, comparison with magnetic resonance imaging classification results, and correlation analysis of risk factors affecting cerebral infarction. Results: The results of the study showed that 942 patients with posterior circulation ischemic cerebral infarction had aortic atherosclerosis (49.04%), small artery occlusion (39.49%), cardiogenic embolism (6.16%), and unexplained type. (5.20%), other reasons (0.11%). There was a significant correlation between DWI imaging characteristics and TOAST classification (χ = 397.785, P = 0.000). Cortical.cortical infarction, unilateral anterior circulation infarction, large perforating infarction, and anterior.posterior circulation infarction were associated with LAA type, and the difference was statistically significant (P < 0.05). Conclusion: The results of the study fully demonstrate that the characteristics of high-resolution NMR imaging are related to the TOAST classification of patients with cerebral infarction caused by posterior circulation ischemia. Traditional risk factors such as age, NIHSS score, coronary heart disease and atrial fibrillation have certain characteristics on DWI imaging. Impact. Therefore, patients with posterior circulation ischemic cerebral infarction need early high-resolution MRI and combined with traditional risk factors to choose treatment options to reduce the disability and mortality of patients.

Conventional Risk Factors

Background: We decided to investigate whether aneurysm wall enhancement (AWE) on high-resolution vessel wall magnetic resonance imaging (HR VW-MRI) coexists with the conventional risk factors for aneurysm rupture. Methods: We performed HR VW-MRI in 46 patients with 64 unruptured small intracranial aneurysms. Patient demographics and clinical characteristics were recorded. The PHASES score was calculated for each aneurysm. Results: Of the 64 aneurysms, 15 (23.4%) showed wall enhancement on post-contrast HR VW-MRI. Aneurysms with wall enhancement had significantly larger size (p = 0.001), higher dome-to-neck ratio (p = 0.024), and a more irregular shape (p = 0.003) than aneurysms without wall enhancement. The proportion of aneurysms with wall enhancement was significantly higher in older patients (p = 0.011), and those with a history of prior aneurysmal SAH. The mean PHASES score was significantly higher in aneurysms with wall enhancement (p < 0.000). The multivariate logistic regression analysis revealed that aneurysm irregularity and the PHASES score are independently associated with the presence of AWE. Conclusions: Aneurysm wall enhancement on HR VW-MRI coexists with the conventional risk factors for aneurysm rupture.
