 Good morning, everyone. I am Dr. Rastu Chathnam, post-graduate student, Department of Radio Diagnosis, Agapthala Government Medical College, NGP Panha Hospital. Today I am going to present a scientific paper on the topic of MR study of lumbar canal hysteresis by morphological grading and Tegel-seq measurement, a cross-sectional study. My moderator is Dr. Rastu Chathnam, Department of Radio Diagnosis, Agapthala Government Medical College, NGP Panha Hospital. I am going to the introduction of the study that the lumbar canal hysteresis is the condition in which the spinal canal narrows to the point at which it can accept the pressure on the nerves that travel through the spine. The etiology is characterized in the considerable developmental and acquired causes. It tends to affect the patient at the younger age from about 30 to 50 years ago. Developmental canal hysteresis is the condition in which there is a narrow by the spinal bone and spinal canal, possibly defecting in the normal developmental process. In disarray of the stenosis, there is a diminished space available for the neural and muscular organs in the lumbar spine, secondary to the designated changes in the spinal canal. Symptoms of the stenosis include the pain in the groin, hips and the back of the toenails or weakness in the legs and the back and in severe cases, acidity in the bowel dysfunction and the seborrheal dysfunction. Magnetic resonance imaging is the investigation of the transduced blood circulation of the patient with the symptoms related to the lumbar spinal canal hysteresis. Hence the present study aimed to assist the lumbar canal hysteresis by morphological grading and Tegel-seq measurement. My index study aims to assist the morphological grade of Tegel-seq in lumbar-central canal hysteresis on MRI. Magnetic and meta-stimular studies, the cross-sectional study, the lewis-hub studies, the one-year place of studies in the Department of Pediatric Diagnosis as a M-C-N-Z-V-Panda hospital. Total number of cases in this study is the 100. Inclusion criteria is the patient with the age of more than 20 years or 20 years and the patient with the symptoms related to the spinal cord in this study. Inclusion criteria is the patient with spinal tumor, spinal fracture, spinal costumative cases were excluded. Heart pacemaker and other metal-implant patients were also excluded from the study. In this study we have collected the 100 cases who were clinically suspected to be a hearing canal stenosis. Eleventh clinical data we have noted for the case files. From the case files. The obtained data we have analyzed with the simple, the statistical data we have represented in the form of table and chart. Mopological grading is according to the study that is the SKS-C-ATOM grading system that is dependent on visual and mopological grading. Which is categorized into the grade 1 to grade 4. Grade 1 is a decrease in previous years. Every species is represented between rootlets, grade 2 is a loss of interest. Every species has a space. Still, seeds are present between rootlets and they can be individualized. Grade 3 is a complete opposite addition of the seeds of the space and rootlets and clumps. Now of course, epiglomeric fat can be normally delineated. Grade 4 is the complete opposite addition of the CSF and the epiglomeric fat cannot be delineated in the grade 4. And the results and the indices started being in the period of 24 months. Out of 100 percent, 46 percent were the males and 50 percent were the females. And the asymptote patient ranges from the 20 years to 78 years. And the maximum of the 26 percent cases were in the age group of 36 to 45 years. Four by the 25 percent of the age group was about 46 to 55 years. Here I'm displaying the age distribution table that is the age of 22 to 25, 26 to 25, 36 to 55, 46 to 55, 68 to 70 years. And the most number of the patients is found on the 36 to 45 of the age group. And the last number was found on the more than 75 years of age. And the result of the grade 2, according to the more political grade, the fine-tuned males, the 40 percent patient was a great one and the grade 2 was the 46 percent was the most contractual, was the 36 percent and grade 4 was the 4 percent. And I'm showing you at the symptomatic eye chart which is the most common one is the back pain as the second one is the groin pain and followed by the numbness and weakness. And contributing factors here is the degeneration, the spondylolisthesis, the special joint, R2-T, and the ligament and plopum, hyper-trudy. Most common is the degeneration. The 96 percent was the most top patient found here and the third is spondylolisthesis, the second and the third is the fascist joint activity followed by the ligament and plopum, hyper-trudy. And here I'm displaying the according to the political grade what is at the level of the algorithm, like higher CSF, which is reduced by CSF times the delineator and that would have no clamping of the nutwoods and no delineation of that effect can be seen here in grade 1. In grade 2, the obstruction of the CSF is great but the epitom fact can be delineated. In grade 3, there is a complete obstruction of the CSF space and along with here in this image we can see the ligament and plopum, ligament and plopum, hyper-trudy and here we can see the clamping of the nutwoods and epitom fact partially and delineated. And the last grade, last political grade was a grade 4 who is at the level of the 4th and 5th level here is the complete obstruction of the CSF space and the epitom fact cannot be delineated in this grade. And the discussion, in our study quality we must find the resistance of the numbers when this classroom in the specific causes include the honey, the x-honey distribution hyper-trudy and the ligament and plopum, hyper-trudy and the joint attribute. In this study, more political grade 2 was the most common as I already discussed in the table and the 46th person and the follow by the grade 3, 36th person, grade 1, 14th person and the lowest to one is the lowest. The common with this one is the grade 4 who is the 4th person. In this study, out of 100 cases, most predominant contributing factor was the degeneration of 96% as already discussed. Spondability studies is the 30% and the joint attribute was the 23% relative to the 16%. In this study, 80% of the patient completing of the epitome of 30% and the epitome of 40% has the 3 million nameless and 20% has the mixed symptoms. In our study, the most common effective as group was the above 40 years of age. As our study is the hospital-based study, modern population-based study, it may not be accurate indicator of the incidence of the different study down from Lambert and this study is bio-political grading. As we know the map MRIs the superior type of modality for the assessment of the percent of the community study as it provides superior software solution and more rootless can be assessed with greater resolution. I will come to the compulsion now. The bio-political grade of the TECALSEC has a significant correlation with the animal measurement traditional analysis of the Lambert center of anesthetics by Canon diameter the cross-sectional study is the time consuming and the operator dependent. As more physical grade of the TECALSEC helps in the quick assessment of the severity of the Lambert genetic stenosis. Hence the more physical grading system helps to reduce in repeat and reliable determination of Lambert genetic stenosis in MRI. And the references here I have provided are 7 numbers of the references which you can control. Thank you.
