Methods and materials
Sixty patients who underwent dual energy PCTA were enrolled in this study.
DECT examinations were performed on a DSCT scanner (Somatom Definition Force,
Siemens Medical Solutions,
Germany).
Scan area started from lung apex to diapragma,
and tube voltage were setted as 80 kVp and 140kVp in all patients.In-house software was used to generate iodine maps and lung perfusion was evaluated in axial,
coronal and sagittal planes.
All patients were evaluated by two radiologists in two separate sessions with consensus.
In first session PCTA were evaluated without iodine maps.
2 weeks later,
in second session only iodine maps without PCTA images were evaluated and the lobes which having perfusion defects were noted.
PCTA examinations were used as reference method and the results of iodine map evaluation were compared to PCTA results.
SPSS V.
23 was used for statistical analysis.
Pearson correlation analysis and kappa consistency test was used between two evaluation results.
