Case Study
Philips CT Clinical Science Philips Healthcare • USA

Clinical history

This 59 year-old female came to the Hennepin County Medical Center complaining of abdominal pain. The technologist used the IQon Spectral CT system to perform an abdomen scan.

The patient's kidneys appeared as normal on conventional CT. However, 40 keV reconstructions showed multiple hypodense areas visible bilaterally (red circle). Diffusion weighted MR imaging confirmed pyelonepritis. Greater than 100,000 organisms/ml Escherichia coli isolated on urine culture.

Clinical significance

Heterogeneity in enhancement of viscera can be much easier to visualize on lower keV monoenergetic reconstructions using the IQon Spectral CT scanner.


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