Suboptimal contrast bolus timing. however, there is no evidence of pulmonary artery embolism. 2.nonspecific bilateral groundglass changes in the lungs, which could represent nonspecific mild interstitial edema. calcified granulomatous in both lungs?

The chest CT angiogram seems abnormal. Pulmonary embolism is likely not present but the parenchymal changes could be the reason for dyspnea (shortness of breath) and the etiology needs to be defined. The presence of calcified granuloma is less likely the reason for this study, just coincidental findings. Take care.

Needs to be co-related with symptoms and physical findings- then repeat imaging to see if the lung findings improve / normalize following appropriate treatment. good luck
