ABSTRACT
Aim of the work: The aim of this study is to evaluate the correlation between pulmonary embolism severity and scoring obtained using multi slice CT [MSCT] and the clinical presentations and echocardiography in patients with pulmonary embolism [PE]
Patients and method: this study was carried out in the Radiology Department of Ain Shams University Hospitals. 21 patients with PE. The CT obstruction index [OI] using Qanadli score and the RV/LV diameter Right ventricle dysfunction ratio [RVD-ratio] using the four-chamber view of the heart were calculated for all patients. The cut-off for the OI to detect RVD was constructed using ROC curve. They were 13 [61.9%] females and 8 [38.1%] males. Their age was ranged from 22 -83 years old
Results: Dyspnea and RVD [RVD-ratio >1] were significantly more common in patients with severe pulmonary embolism. Regarding the echo findings with PE high Right ventricular systolic pressure [RVSP] was the commonest echo finding among our studied patients. The cutoff point of obstruction index [OI] >15 [Qanadli score >37.5 %] has the highest prediction value of right ventricular dysfunction, indicating that most of the patients with a score of more than 37.5% had RVD that was agreed with echo findings
