 Hello, good evening everyone. I am Dr. Prashan Das, junior resident in the department of radiology in Indochina Medical College and Hospital Kolkata. And my paper is on Diagnostic FDC property tomography of chest in evalution of pulmonary tuberculosis, pediatric patient in church, at the hospital, retrospective study and the guidance of Dr. Malik Parmukh, who is our esteemed associate professor in our department in the institution. As you will know the introduction of microwave tuberculosis is the most devastating matrix of all that and epidemiology is significant mode of transmission on the airborne with the infection occurring through the inhalation. Pediatric tuberculosis always occurs by the contact of adult or adolescent with capillary pulmonary tuberculosis in most of it at home or also in school. But contact killer is not a sufficient with genealogy and it affects also is important and children in less than five years of age there is a late age system that is decimated from the much more common and child to child transmission is extremely rare. This pediatric population is typically a positive state variant with difficulty in achieving the different in microbiology of conformation. And the microbiology in the manifestors may be the just poor word gain or the typical TB symptoms and the radiology president is completely different for the adult variant. And primary TB in this portion any company from the environment and the environment and the pathogen, the predominant part of the epidemic is typically not, if you found not detected by the chest radiograph for this we use complete tomography. Also, we can be used we can use city we did it unusual completed or distributed presentation of the disease. We can also do head city in military tuberculosis associated with that. And we also do the inconclusive test extra findings of the positive tuberculosis test in older children we can also do cities can in those patients also. We also know the city can is very much good for the taking the subtle and my parents camel disease. The city is more expensive and require IV confidence and the dose modulation is very much important use the way to best pay the CT protocol. The aims and objectives are to compare the CT and just a little for the diagnostic. The diagnostic techniques we really do in the confinement in the infunduopathy and to ask the city findings to evaluate the need for the need for the execution of the diagnosis. And the matter we take, we take the patient on electricity evaluate the reports on January 2010 to December 2020, the patient less than 16 years diagnosed with active TB in our, our hospital, and we also recorded on the medical records demographic analysis. We included the patient only the really less than 16 years of age or having the final diagnosis actively confirm probability but we excluded the patient who have only extra pulmonary TB or immunodeficiencies or syndromic approach but we also excluded the patient with a non tuberculosis also and and the patient with already on 80 T. We also included from the study and the man to test was performed for 0.1 mm on the interpreter forum and the test result was considered positive as you all know. And the examination as you can see with the gastric washing was open with three consecutive days and from then the gildance and culture for immaculability was evaluated. The test was done and all the patients that CT were done is only one of those patients were only performed after the chest X-ray paragraph which is evaluated the unusual findings of the mass infections also the complications like the detailed complications like arrow and arrowing or Vita eclectasis. And the CT examination performed with the CT patient beyond one of one the supine question and also give a low similarity contrast regionality contrast reasons to establish the media study environment of tuberculosis and also set to see in the strategy analysis well done the P less than 0.0 were considered statistically significant. And we found the results to 41 patients out of the 20 year male and 35 were symptomatic and the most common symptoms are fever which found in 28 children and the pulmonary tick was confirmed 34 patients and the four patients CT was not performed because the patient did not give consent and there are several types of consultation the more commonly considered segmental pattern which found in 15 cases and there are other variants nodular and lower heretics also found and the nodules, the nodules, the pulmonary cavular nodules are found in 13 cases, three in five cases and the nymphenolpathy was 33 children on CT. And this nymphenolpathy we found that the only six patients were nymphenolpathy one at least one nymphenolpathy we can get and then 20 mm which is significant. And the nine patients were really nymphenolpathy less than 10 mm. And microbiology confirmed patient get the four patients having the nymphenolpathy greater than 20 mm. Also evaluated also the nymphenolpathy enhancement or contrast enhancement so the most commonly classic enhancement pattern also is there which found only the five four children. The four children, tail generavers for the homogenous enhancement also found the calcification so found five different form calcification present five children, laser fibers, the most more common is the point types of calcification. These are the chart we found the CTs and finding consultation nodules centri-lobal patterns or centri-lobal stream but apparently this is the right side the nymphenolpathy types like ring calcification enhancement homogenous enhancement calcification pointed or shield or the size of the nymphenolpathy. And also the nymphenolpathy the only pathological findings. And this is the picture the high-year-old completely malnourished by confirmed patient. And chest checks there is an opposite of a CPC leg envelope and followed by confirmed by CT. And also there is subcral region in the prominent link node. And another one this is a common in the media still nymphenolpathy noted and with necrosis and there is a component homography contrast enhancement for peripheral consultation the left lower loop also. And this is an eight-year-old who is in recurrent lung infections with with cough. This one is a consultation of the volume in the left lower right middle and also there is a finding the left palmyra high-level is compressed with the left due to the bronchial compression is done. We have seen because adenopathy in the left palmyra high-level. And this is also the cavity relation which comes from cavity relation in the apex in the right lung is corresponded with the CT. In the discussion we found that the children younger patient with the physiological thymic protrusion limits the professional of the pain radiograph. So the enlarged lymphenolpathy only projected only prevalent only when projecting over the heart and the thymus. And the lateral progression improved by this projection is not always easy to perform with children. So CT is useful is there. Most commonly found in CT is adenopathy. The 89% of them 81 as a higher one followed by paraguar-paractrical region. And our study the most common pattern of enhancement was homogeneous contrast enhancement followed by peripheral ring enhancement. And one single case of inhomogeneous enhancement. This is the Moon is also the study of Mukun study but the most commonly pattern was inhomogeneous. This is contrary to our finding. In our study the seven children were treated by the seven children for cavitation. So we know the cavitation is a high-infected high-bacterial load. So it is a typical feature of adult type which also we see in all the children type is less rare one. And last pattern was parancamination. The nearly three were found in our in four children. Four so the three of them are less than five years. So also we know that the immunity was less in that patients. In our study the plural inhomitable found in nine patients. Three patients with pulmonary effusion six patient with ulterior fur, sorry three patients with ulterior effusion six patients with ulterior fur, thickening is noted. And this conclusion is the delayed diagnosis of the TB patient usually due to the failure due to high load and the amnesia in panangati and CT scan of chest for the advantage of the conventional riddle of the adiatic patients and the limitations of this retrospective nature. నివాభ౗ాను మాగును చిసృరామిం మాస్టక్లిఆద్డజసిను Australia స్వా, నివాను, పురరి భాస్య, పురాసికలాము ంిస్ఠెచినినిటదికేటరి. విస్లికుత్
