Preliminary Assessment of Added Diagnostic Value of Dual Energy CT Images Using Data Acquired on a Spectral Detector CT

Preliminary Assessment of the Added Diagnostic Value of Dual Energy Computed Tomography (DECT) Images Using Data Acquired on a Spectral Detector Computed Tomography (SDCT)

Study hypothesis: Post-processed SDCT images provide additional diagnostic value over conventional CT datasets.

The CT examination would be a clinically-necessary, standard-of-care CT performed as per the clinical indication. The protocol and scan parameters for the CT exam will be similar to that of an equivalent scan performed with any other CT scanner. There would be no additional scanner of injection of any drug specifically for the study. The conventional CT images generated by the scanner will be used for clinical purposes as routinely practiced.

Inclusion Criteria:

• a patient scheduled for a clinically indicated CT scan for one or more of the following body regions/organ systems:
• head and neck
• body (chest and abdomen/pelvis)
• cardiovascular structures.
• these scans may be without contrast, with contrast enhancement, or CT angiograms.

Exclusion Criteria:

• under the age of 18 years old
• standard exclusion criteria for CT scans
