Segmental Scoring In Covid 19 Pneumonia On HRCT Chest

Abstract

Aims:To understand the common patterns of CT Chest in Indian population who have proven to be RT-PCR COVID positive and/or suspected COVID with RT-PCR negative.Settings and Design: Descriptional study done in patients of Dr. D.Y. Patil Hospital and Yashwantrao Chavan hospital which have COVID-19 ward. Methods and Material:CT chest was employed in patients with both confirmed and suspected COVID-19 pathology have been recognized in our study. Association with COVID-19 infection was based on Reverse transcription polymerase chain reaction (RT-PCR) method. Statistical analysis used: The data was entered in MS EXCEL spreadsheet and analysis done using licensed Stastical Package for Social Sciences (SPSS) version 21.0.Descriptive statistics for each parameter were computed for different variables. Results:Commonly found were ground glass opacities, consolidations, septal thickening often showing bilateral involvement. New segmental scoring system is provided with division based on the anatomical bronchopulmonary segments. Grading done <12-Mild, 12-24 – Moderate, > 24 – Severe. Conclusions:Study provides us with knowledge to use CT thorax as an excellent modality in the initial evaluation as well as follow up in COVID-19 positive and suspected cases.
