 Good evening, everyone. I am Dr. Amar Prakash. I am here to give paper presentation on prevalence of interstitial lung abnormalities in HRCT chest. My guide is Dr. BK Soni, Professor, HOD of the Department of Radio Diagnosis, INH Ashwini. I am finally a resident in Institute of Naval Medicine, INH Ashwini, Colaba, Mumbai. So, in introduction, we will, since we will see interstitial lung abnormalities are radiologic abnormality. And on chest CT, it is thought to be an early and mild form of pulmonary fibrosis. There is a growing awareness of the clinical significance of interstitial lung abnormalities incidentally found in the chest CT. So, a possible association between interstitial abnormalities and idiomatic pulmonary fibrosis has been found in the literature. And there are reports that interstitial lung abnormalities can progress to clinically significant interstitial lung disease. So, with keeping this in mind, we have to have a how problems are these interstitial lung abnormalities. So, with the recent development of endic fibrosis therapy for the patient with interstitial pulmonary fibrosis, early identification of these interstitial lung abnormalities has become important. And for their management, we have to start early treatment. So, and however, there are very few specific study on this topic, which is why I am here. So, my aim is to found the prevalence and to know the significance of interstitial lung abnormality which can progress to idiomatic pulmonary fibrosis. So, my study design is observational study at Ashwini Colaba. And my duration was two years with ethical committee approval. And my sampling was 114 and data collection was obtained after HRCT chest of the patient who give their consent to the study. And data which included name of the patient age, basic details and the chest finding and interstitial lung abnormalities finding and data was collected and compiled. The data was divided into classified into radiological abnormalities like reticulations, mosaics, ground glass, intraction, bronchitis and honey combing. So, what I have found is that there is a overall incidence is 4% which is quite high and we have to detect it early and we have to recommend according to the situation of the patient. And to the progression of the disease so that it can be, that progression of this interstitial lung abnormality to the fibrosis can be stopped at that point of time. So, what I have found is reticulation found in 66% of the patient who have found out to be a interstitial lung abnormalities out of 115-4 patient. I have found out in 45 patients which is 4% and out of that total 45 patients, patient were having reticulation was 66% ground glassing in 57% traction bronchitis in 37% mosaics in 8.8% and honey combing in 8.8%. So, there is a possible correlation between idiopathic pulmonary fibrosis and interstitial lung abnormalities. So, the my emphasis is the incidence of interstitial lung abnormalities to the patient who are undergoing HRCT chest is quite high that is 4%. So, we have to have in mind where if the interstitial lung abnormalities have been found we have to accordingly guide the treating physician or the guide to the patients. So, there is a high probability of interstitial lung disease that radiologist would recommend a general approach to the interstitial lung disease if there is a high probability of interstitial lung disease in interstitial lung abnormalities patients. So, basically the radiologist should be aware of the relevant and irrelevant radiological finding of interstitial lung abnormality and review them with consideration of clinical symptoms and pulmonary function. So, my emphasis is on to do not ignore the interstitial lung abnormalities and these are quite high with respect to the patient who are undergoing HRCT chest. So, there is a high probability to get converted into idiopathic pulmonary fibrosis and so that radiology should be aware and recommend a general approach to interstitial lung disease. These are my references. Thank you very much.
