Recent publications and our experience suggest role of DECT in thoracic malignancies for differentiating benign versus malignant lesions as well as for assessing treatment response. Teaching points of our educational exhibit are A. Specific scanning protocol and contrast injection delay time are required for evaluation of patients with intrathoracic masses with DECT. B. Use of DECT datasets to generate blended, monoenergetic and perfused blood volume image types C. Differences between the qualitative interpretations of DECT datasets versus single energy chest CT. D. Role of quantitative indexes of contrast uptake in the thoracic masses from DECT datasets in characterization of thoracic masses. E. Role of DECT for assessing treatment response F. Radiation dose with DECT can be similar to single energy routine chest CT protocols.  

1. Scanning protocol and contrast injection techniques 2. Image processing of DECT datasets 3. Qualitative evaluation of processed images 4. Quantitative metrics of DECT in thoracic oncology: Relative contrast enhancement and iodine concentration 5. Advantages and limitations 6. Pictorial depiction of teaching points with series of cases from our institution
