Background: Pulmonary embolism is a cardiovascular emergency that requires immediate treatment, therefore it is necessary to have an accurate imaging diagnosis pulmonary embolism to reduce mortality due to pulmonary embolism, one of which is using virtual angioscopy CT scan (CTVA) which uses three-dimensional (3D) surface view volume rendering perspective (pVRT) and need a method to assess the amount of vascular obstruction, the degree of obstruction and the location of the embolism, one of which is the CT obstruction index / Qanadli score. Objective: To determine...

Materials & Methods:An analytical observational study with retrospective data and a cross-sectional study design involving 60 research subjects who have been previously proven with pulmonary embolism in the form of secondary data, that is medical record data and DICOM (Digital Imaging and Communications in Medicine) data, then re-evaluated by assessing the Qanadli score using CTVA and the pulmonary artery branch labeling method which has been simplified by two radiology doctors from November 2019 to January 2021

Result: In 60 research subjects, 32 people died and 28 people lived, by using statistical analysis unpaired t-test on age characteristics with a mean age ranging from 45 ± 15 years having a p value of 0.413 (p value> 0.05), and using the Chi Square test analysis on the gender characteristics consisting of 23 men and 37 women who have a p value of 0.887 (p value> 0.05), and those who have comorbid range are 35 people and 25 people who do not have comorbids...

Conclusions: There was a significant correlation between the CTOI score (Qanadli score) using CTVA and labeling pulmonary artery tree with the outcome of pulmonary embolism. This research is expected to contribute knowledge to Virtually three-dimensional imaging of pulmonary vascular intraluminal stenosis (3D) to clinicians and radiologists as well as initial data that can be used as reference for further research and CTVA can accurately diagnose and predict pulmonary embolism so that management can be optimized.
