Zusammenfassung
Ziele: To assess the image quality of different heart-cycle-synchronized MDCT reconstruction techniques for volume rendered 3D visualization of the bronchial tree. Methode: Non-ECG-gated and retrospectively ECG-gated MDCT was performed in 25 patients. The ECG-gated raw data were reconstructed using absolute reverse delays of 200 to 500 msec. The same raw data were reconstructed using kymogram-gated technique in 10 phases of the cardiac cycle. For both reconstructions the optimal artifact-free diastolic phase was determined. Volume rendered reconstructions of the bronchial tree were generated from these two data…
