Tumor in the duodenum

Case Study
Philips CT Clinical Science Philips Healthcare • USA

Clinical history

This elderly patient arrived at the emergency department with a gastrointestinal hemorrhage. The patient underwent an endoscopy, which located the source of the bleed in the duodenum. The clinician ordered a CT scan on the IQon Spectral CT scanner.

The spectral results from the images acquired on the IQon Spectral CT system enabled the clinician to delineate a tumor in the duodenum not previously identified on conventional images.

Clinical significance

Since the IQon Spectral CT scanner gathers spectral data every time a patient is scanned, the clinician was able to utilize spectral results from this scan. This is an excellent example of how spectral results can provide enhanced diagnostic capabilities, even in patients who would not have been pre-selected for dual-energy techniques.


Results from case studies are not predictive of results in other cases. Results in other cases may vary.
