A STUDY ON THE VALUE OF DUAL-ENERGY COMPUTED TOMOGRAPHY IN THE DIAGNOSIS OF ACUTE PULMONARY EMBOLISM
Main Article Content
Abstract
Objectives: This study aims to describe the imaging characteristics of pulmonary embolism using Dual-Energy Computed Tomography (DECT) and to determine the relationship between DECT, computed tomography pulmonary angiography (CTPA), D-dimer, NT-proBNP. Methods: A cross-sectional study was conducted on 56 patients suspected of having pulmonary embolism. These patients underwent both CTPA and DECT imaging at Gia Dinh People's Hospital from October 2022 to April 2024. Results: DECT is superior to CTPA in identifying embolism in small branches of pulmonary arteries. A significant positive correlation was found between NT-proBNP, D-dimer levels and concentrations with the presence of pulmonary embolism as detected by DECT. Conclusions: DECT is a valuable diagnostic method in detecting acute pulmonary embolism, helping to improve clinical effectiveness and make timely treatment decisions.
