Objective To compare the clinical value of two kinds of imaging methods including CT and MRI in early diagnosis of acute multiple cerebral infarction. Methods The imaging data of CT and MRI of 108 patients with acute multiple cerebral infarction were analyzed. The total detection rate, the detection rate in different time periods,the number and area of detected lesions and the inspection time of CT and MRI in early diagnosis of acute multiple cerebral infarction were compared. Results The total detection rates of patients with acute multiple cerebral infarction by CT and MRI were 57. 41%,96. 30%,respectively. The total detection rate of MRI was significantly higher than CT(χ2 =9. 73,P<0. 05). The detection rates of patients with acute multiple cerebral infarction for onset within 24h and 24-72h by MRI were significantly higher than CT(χ2 =18. 54,16. 20,all P<0. 05). There was no significant difference in detection rate of patients with acute multiple cerebral infarction for onset >72h between CT and MRI(P>0. 05). The number of detected lesions of patients with acute multiple cerebral infarction by MRI was significantly more than CT(t=2. 39,P<0. 05). The area of detected lesions and the inspection time of patients with acute multiple cerebral infarction by MRI were significantly less than that by CT(t =2. 43,2. 60,all P <0. 05). Conclusion Compared with CT, MRI in the early diagnosis of acute multiple cerebral infarction can effectively improve the detection rate in early stage, avoid the missed diagnosis of small lesions and is helpful to shorten the examination time.

Osteoporotic vertebral compression fracture (OVCF) can lead to lower back pain and may be even accompanied by scoliosis, neurological dysfunction and other complications, which will affect the daily activities and life quality of patients. Vertebral augmentation is an effective treatment method for OVCF, but it cannot correct unbalance of bone metabolism or improve the osteoporotic status, causing complications like lower back pain, limited spinal activities and vertebral refracture. The post-operative systematic and standardized rehabilitation treatments can improve curative effect and therapeutic efficacy of anti-osteoporosis, reduce risk of vertebral refracture, increase patient compliance and improve quality of life. Since there still lack relevant clinical treatment guidelines for postoperative rehabilitation treatments following vertebral augmentation for OVCF, the current treatments are varied with uneven therapeutic effect. In order to standardize the postoperative rehabilitation treatment, the Spine Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized relevant experts to refer to relevant literature and develop the "Guideline for postoperative rehabilitation treatment following vertebral augmentation for osteoporotic vertebral compression fracture (2022 version)" based on the clinical guidelines published by the American Academy of Orthopedic Surgeons (AAOS) as well as on the principles of scientificity, practicality and advancement. The guideline provided evidence-based recommendations on 10 important issues related to postoperative rehabilitation treatments of OVCF.
