Abstract

Introduction: Lung perfusion scan, as diagnostic imaging procedure in Nuclear Medicine, is used to assess blood flow within the lungs. We evaluated the ratio between lung perfusion scan scans, chest x-ray and compared with the number of d-dimmer tests in patients with very low clinical probability of pulmonary embolism.

The purpose of this presentation is to review the diagnostic results in order to choose the most appropriate objective test for the diagnosis or exclusion of pulmonary embolism.

The Methods: One hundred and four (104) patients, who underwent a lung perfusion scan suspected of pulmonary embolism, were analysed from April 2017 to August 2019.

Results. The average age of the patients was 54.17 years; 59 (56.73%) were women, 45 (43.24%) were men. Fifty-five 55 (52.88%) of 104 patients had positive lung perfusions an results for pulmonary embolism, 33 (33.65%) had negative results, 9 (8.65%) were evaluated as suspicious, and 5 (4.8%) with non-typical perfusion defects. LA D-dimmer levels less than 250 ng/ml. were considered negative, and were found in 31 (29.81%), a positive D-dimmer result for Pulmonary Embolism (> 250 ng/mL), was found in 73 patients (70.19%) and had a sensitivity of 75.34% (interval 95% confidence interval, 0.29–0.97) and a negative predictive value of 88.57% (95% confidence interval, 0.62–0.98). We found a significant difference in D-dimmer levels in patients with an abnormal lung perfusion score (mean, 750 ng/mL) compared to patients with a normal lung perfusion score (mean, 250 ng/mL) (P = 0.01, X 2 test).

Discussion: Lung perfusion scan has the potential to become a first-line tool for the diagnosis of pulmonary embolism, especially in acute cases. Based on the standard technology and the new comprehensive criteria, and the assessment of the need for the required tests in these patients, it is imperative to make an early diagnosis of pulmonary embolism and the adequate interpretation. Without a doubt, treatment is fundamental.
