Dr. Gerald Mandell answered

Different chest CTs: High resolution chest CT usually with out intravenous contrast is used to define interstitial lung disease pattern, whether diffuse or localized process. CT of chest examination with contrast intravenously usually looking for tumors or metastases and acute infection in the lungs.
