“…Several previous studies have suggested that pulmonary arterial embolic burden assessed by CT as well as by RV/LV ratio is also a predictor for APTE patients (9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20). On the other hand, Ghaye et al (19) suggested that RV/LV diameter ratio and azygos vein diameter were significant predictors, and that pulmonary arterial embolic burden was not.…”

“…According to the past literatures (14)(15)(16)(17)(18)(19)(20), the scans were evaluated by measuring the minor axes of the right and left ventricles of the heart in the transverse plane at their widest points between the inner surface of the free wall and the surface of the interventricular septum. These maximum dimensions may be found at different levels.…”

“…Currently, multidetector-row CT (MDCT) pulmonary angiography can be used to identify clots within distal pulmonary arteries (PAs) with high sensitivity and specificity, and can indicate alternative diagnoses and underlying lung diseases. In addition, some investigators have used several parameters to evaluate the accuracy of CT scoring systems for PA clot assessment as well as right ventricular (RV) failure assessment (9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20). MDCT has therefore become the first imaging examination for suspected acute PTE (APTE) patients (9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20).…”

Purpose: To compare directly the capabilities of multidetector-row computed tomography (MDCT) and MRI for disease severity assessment and outcome prediction for acute pulmonary thromboembolism (APTE) patients. Materials and Methods:Fifty consecutive APTE patients underwent MDCT, MR angiography, dynamic perfusion MRI, treatment and follow-up examination. Pulmonary blood flow (PBF), pulmonary blood volume, and mean transit time maps were generated from perfusion MRI, and all segmental parameters were determined by using region of interest measurements. Receiver operator curve analyses were used to determine the most accurate parameter for diagnosis of the APTE segment. Then, APTE index from perfusion MRI (PE perfusion MRI index), right ventricle/left ventricle (RV/LV) diameter ratio and APTE indexes from embolic burdens observed on MDCT (PE CT index) and MR angiography (PE MRA index) were calculated. Finally, ability to differentiate mortality (n ¼ 8) from survival (n ¼ 42) groups and to predict patient outcome were statistically assessed.Results: PBF was a significantly more accurate parameter than others (P < 0.05). When feasible threshold value was applied, specificity and accuracy of RV/LV diameter ratio and PE Perfusion MRI index were significantly higher than those of PE CT and PE MRA indexes (P < 0.05). Logistic regression analysis demonstrated that each index was a significant predictor (P < 0.05).Conclusion: Dynamic perfusion MRI can be effective for disease extent assessment and outcome prediction for APTE patients.
