 Good morning to one and all myself Dr. Shravanesh Patil, Department of Radio Diagnosis, T.Vapadil Hospital, Nehrual, Nambay. Title of my paper is H.R.C.T. Bhatan in follow-up cases of COVID-19 pneumonia. A brief introduction, the disease was spreading at an alarming speed. The first case was discovered in our hospital in the month of March 2020. COVID-19 infection primarily affects the lung and shows typical SRJT changes which include ground glass opposite which is the most common feature, which is multi-focal centralabular peripheral and subcleronine distribution, there can be associated airspace consolidation, there can be vascular dilatation, fibrodech changes which can be seen in the form of traction bronchitis, fibrosis and crazy paving pattern. There is variable H.R.C.T. Bhatan in resolution absorptive stage of the COVID-19 pneumonia. These changes can range from complete resolution in the form of normal appearance of the lung, pharma to variable level of fibrosis and post-infection de novo interstitial lung disease pattern. Advanced phase of the disease is associated with increased frequency of fibrodech streaks, there can be architectural distortion, subsegmental electrolysis, secretarial and bronchectatic changes and mosaic at innovation changes on H.R.C.T. The follow-up CT was assessed for severity and progression of the COVID-19 pneumonia. Correlation among particular age group and imaging funding in the H.R.C.T. thorax was done using appropriate analysis technique. Depending on the extent of residual fibrosis, progrosis and the disease progression can be assessed. Here in the author, quantify as such changes in a follow-up case of COVID-19 infection and try to determine the extent of disease on lung post COVID with respect to particular age group. Long-term prognosis of the post COVID-19 pneumonitis is dependent on extent of residual fibrosis which can be assessed on follow-up H.R.C.T. thorax study. Methodology from March 2020 to September 2021, the follow-up H.R.C.T. thorax scans were obtained in a post COVID positive patient. The participants were divided on the basis of their follow-up CT scan funding which includes those with CT evidence of fibrodech-like changes which include traction bronchectasis, parent camel band or anicomba, those patients with residual bronchosopacitis, those with mosaic attenuation pattern and those showing normal lung parent gamma. These findings were later correlated with age group. H.R.C.T. scan of the thorax was done within a section using G-Optima 128 slice and the scan was done from thoracic inlet to the diaphragm. All 99 patients got follow-up H.R.C.T scan. The CT images were reported by two consultant radiologist. These consultant observed, interpreted and reported the CT features using axial and multi-planar reconstructed images. So, fibrodech-like changes on H.R.C.T. is defined as presence of fibrodech-parent camel bands, anicomba and traction bronchectasis. The aim and objectives are to assess and to quantify H.R.C.T. changes in a follow-up case of COVID-19 infection and to determine the extent of disease on lungs in post COVID patient of a particular age group. The results, this is a chart which depicts the following. On follow-up H.R.C.T. thorax, following was observed. Fibrodech-like changes was seen in 79 of the 99 participants. Restodoral ground-glass opacities was seen in 59 of the 99 participants. Mosag attenuation pattern was seen in 12 of 99 participants and complete resolution that is normal lung parenchyma was seen in 10 of 99 participants. These findings were later correlated with age group in a sample size of 99 patients. Majority of the patient belonged to 41 to 60. Out of them 49 showed positive H.R.C.T. findings and 7 showed normal lung parenchyma. In the age group 20 to 40, 19 of the 22 patients showed post COVID-19 sequelae and 3 patients showed normal lung parenchyma. Patients in the age group 60 to 80 and 80 plus 20 out of 20 patients in the 60 to 80 had post COVID sequelae and 80 plus patient 2 out of the 2 patients had post COVID sequelae. So conclusion of my study is that in follow-up H.R.C.T. in patients who suffered from COVID-19 pneumonia predominantly showed Fibrodech-like changes in lung parenchyma in more than 80 percent of the patients followed by Restodoral ground-glass opacities which was the second predominant funding in 62 percent of the patient and the patient belonging to the age group of 41 to 60 were the most susceptible to these H.R.C.T. findings. So monitoring of this patient with follow-up H.R.C.T. study and with appropriate antibiotics can be advised in this age group. Thank you.
