Research Abstract |
FPD-CT has a potential to obtain chest image with marked reduction of radiation exposure as 1/30 to 1/50. In comparison of CT images at supine and sitting position, the physiological postural change of ventilation and blood flow was observed. It was proven that the size of the smallest GGO nodule was 5mm and 8mm with -650HU and -800HU respectively in phantom study. In clinical study. FPD-CT was significantly superior to chest x-ray in detecting pulmonary nodule while with identical radiation dose to chest x-ray.
