- •
A new CT technique for identifying ischemia in small bowel obstruction is proposed.
- •
Virtual monoenergetic imaging at 70 keV increases conspicuity of small bowel mucosa.
- •
Contrast resolution is better on VMI at 70 keV when compared to conventional CT.
- •
Equal diagnostic acceptability noted between the VMI at 70 keV and conventional CT.
- •
Increased diagnostic confidence reported on the VMI at 70 keV images.
