In brief: The list

is long. It can show almost everything that can be seen with a contrast enhanced scan.
It can't diagnose PE however.

In brief: A few things

Interstitial lung disease and bronchiectasis, sometimes areas of emphysema can be shown.
Contrast is usually needed to differentiate lymph nodes from other structures, metastatic disease,, abscess and tumor necrosis as well as pulmonary embolism.
