“…Recently, similar studies have been performed to evaluate LV function with MSCT [12][13][14]. Juergens et al [12] have evaluated the LV function in 30 patients known to have or suspected of having coronary artery disease.…”

“…Technical progress has made possible prospective and retrospective synchronization of the patient's ECG trace with spiral CT data acquisition. With retrospective ECG synchronisation technique, diastolic and systolic images can easily be produced from the multi-slice spiral CT data sets, which were acquired during the entire cardiac cycle [11][12][13][14]. From diastolic and systolic CT images, right (RV) and left ventricular (LV) volumes such as end-diastolic and end-systolic volumes and consecutively, the assessment of both RV and LV ejection fraction is potentially feasible.…”

This study aimed to assess the feasibility of cardiac global function evaluation during a whole-chest multi-slice CT (MSCT) acquisition in patients referred for suspicion of pulmonary embolism (PE), and to compare the results with planar equilibrium radionuclide ventriculography (ERNA). Ten consecutive haemodynamically stable patients (six female, four male; mean age 69.7 years; heart rate 65-99 bpm) with suspicion of PE underwent an MSCT and ERNA within a 6 h period. CT acquisition was performed after contrast medium injection by using 16x1.5 mm collimation and retrospective ECG gating. Left ventricular (LVEF) and right ventricular (RVEF) ejection fractions were calculated using dedicated three-dimensional software. Relationships between measurements obtained with MSCT and ERNA were assessed using linear regression analysis and reliability of MSCT was assessed with intra-class correlation coefficient. Bland-Altman analysis was performed to calculate limits of agreement between MSCT and ERNA. MSCT was performed successfully in ten patients with a mean acquisition time of 16.5+/-2.8 s. Functional cardiac evaluation was possible on CT for all patients except for one due to poor opacification of right ventricle. Linear regression analysis showed a good correlation between MSCT and ERNA for the LVEF (R=0.91) and the RVEF (R=0.89) measurements. Intra-class correlation was superior for LVEF (0.92) than for the RVEF (0.68). Bland-Altman plots demonstrated that MSCT substantially overestimated the ERNA RVEF. Morphological CT data demonstrated PE in four of ten of patients and alternative diagnoses in five of ten patients. Our study reveals that MSCT with retrospective ECG gating may provide in one modality a morphological and a functional cardiopulmonary evaluation. Comparison with ERNA demonstrated a good correlation for both ventricular ejection fractions.

Background: cardiovascular diseases are among the principal causes of mortality and morbidity worldwide. Prevention, early diagnosis and treatment can play an important role in reducing complication of cardiovascular diseases. Objectives: Considering increasing popularity of cardiac computed tomography CT angiography (CTA) in one side and also magnetic esonance angiography (MRA) as gold standard modality on the other side, we decided to perform this meta-analysis study to compare cardiac CTA and MRA in evaluating left ventricular volumes. Method: this study is a systematic review in which we included all studies with inclusion criteria and without exclusion criteria up to 30 December, 2019. Studies were selected after searching on different databases and articles in bibliography of included studies. Obtained studies were screened for quality. Required data were extracted and were then analyzed via STATA 11 statistical package. Results: among 90 articles obtained in primary search, finally 19 studies entered data extraction and synthesis. Based on our meta-analysis, standardized mean difference was -0.09 (95% CI -0.2, 0.02) for end systolic volume (ESV), -0.10 (95% CI -0.22, 0.01) for end diastolic volume (EDV), 0.10 (95% CI -0.01, 0.22) for ejection fraction (EF) and -0.09 (95% CI -0.23, 0.04) for stroke volume (SV). Conclusion: Results of this systematic review and meta-analysis showed that there is no statistically significant difference between CTA and MRA in evaluating ESV, EDV, EF and SV. Based on our findings, it can be interpreted that CTA has similar accuracy with MRA in evaluating ventricular volumes.
