ABSTRACT
Objective To discuss the application value of MSCT in the diagnosis of acute appendicitis.Methods 30 patients with appendicitis were enrolled as a research group,meanwhile 30 healthy adults without any diseases were as a control group.Some MSCT findings were observed or measured including diameter and position of appendix,fluid and gas density in appendix cavity, periappendicural fat density and peritoneal thickening,ascites and so on.Results The outside diameter of acute appendicitis appen-dix was (9.78±2.33)mm on average,whereas the diameter of normal adults appendix was (5.05±0.53)mm,exhibiting a signifi-cant difference (t=24.85,P <0.01).Rough periappendicural fat with increased density in 25 patients (83.33%)with the CT value of about -40 to 20 HU,exudation and peritoneal thickening around the appendix in 13 (43.33%),thickening and edematous appen-dix walls in 29 (96.67%),fecal stone in the appendix cavity with high density in 9(30.00%),the appendicitis in combination with intestinal obstruction in 1 (3.33%),and the appendicitis with peritoneal thickening in 80.00% and with peritoneal effusion in 23.33%were found in the study.Conclusion Full abdominal MSCT can help to the diagnosis of acute appendicitis,and some MSCT findings can be useful for the diagnosis including the appendix diameter≥6 mm,appendix cavity effusion,lumen stone,peripheral increased adipose density and peritoneal effusion.
ABSTRACT
Objective To observe the therapeutic efficacy of electrical stimulation and balloon dilatation in treating cricopharyngeal achalasia after a brainstem stroke.Methods Thirty dysphagia patients with cricopharyngeal achalasia after a brainstem stroke were randomly divided into an experimental group and a control group, each of 15.The experimental group was given real-time electrical stimulation and balloon dilatation, while the control group was treated using common electrical stimulation and balloon dilatation.Results Twenty-six patients in the 2 groups returned to oral feeding after treatment.Videofluoroscopy revealed that the cricopharyngeal sphincter had relaxed and the food passed successfully when swallowing.No aspiration was observed.There was no significant difference in swallowing between the two groups, but the average treatment time, days of treatment and cost of therapy in the experimental group were significantly less than in the control group.Conclusions Either real-time electrical stimulation or common electrical stimulation combined with balloon dilatation can treat dysphagia effectively, but the former can shorten the course of treatment and lower its cost.
ABSTRACT
Objective To improve recognition of the processus articularis arthropathy.Methods CT findings of the processus articularis arthropathy was analysed.Results According to the CT findings of the 94 cases processus articularis arthropathy,CT signs and the syndrome of this disease were summarized five types:①zygapophyseal hypertrophy and osteophyte formation;②stricture or asymmetry of articular space ;③vacuum phenomenon of articular space ;④pachynsis or calcification of articular capsule ;⑤articular instability.Conclusion The processus articularis arthropathy is a very high incidence of a disease.The CT scanning is very important significance to the disease.
ABSTRACT
Objective To improve the knowledge of lumbar posterior marginal cartilagionous node.Methods CT findings of lumbar posterior marginal cartilaginous node in 52 cases were analyzed.Results Three CT characters were:summarized cartilagionous node,centrum posterior marginal osseous absence and protruding follicle ring fragment.Conclusion CT scanning hes defiuite diagnositic value for the lumbar posterior marginal cartilaginous node.
ABSTRACT
Objective To discuss the diagnostic value of the lumbar intervertebral disc degeneration by CT scanning.Methods The clinical representation and CT view of 809 cases with degenerative lumbar intervertebral disc were retrospectively analyzed.Results According to the different CT representation character,the degenerative lumbar intervertebral disc may be divided into the lumbar intervertebral disc denaturation bulge in 96 cases and the lumbar intervertebral disc herniation in 713 cases.Conclusion CT scanning is a value method to diagnosing degenerative lumbar intervertebral disc.
ABSTRACT
Objective To study the value of common X-ray and CT scanning in the spinal bursting fracture (abridged English:BF).Methods By the frontal,lateral X-ray film and CT scanning,the imaging manifestations of BF in 43 cases were analysed,contrasted,summarised and classified .Results Among the BF 43 cases,the classifications were type A(10 cases),type B(15 cases),type C(2 cases),type D(9 cases) and type E(7 cases).The three-post injure had 34 cases,the two-post injure had 9 cases,the spinal canal narrowing:0?was 8 cases,1?was 12 cases,2? was 23 cases;the rear spinal edges discontinuation was 35 cases.Conclusion The diagnostic value of X-ray film to BF is reflecting the bones injured change of spinal fracture type,flexion and damaged rear edge.The CT scanning advantage is showing the fracture lines trend,relative scope,degree of spinal canal deformation and narrow,infering the pressed situation and injured spinal cord.The two methods combine and confirm each other in order to help clinical diagnosis the right treating.
