Renal lesions made easy!
58 year old male, with a history of >30 prior abdominal surgeries presents with abdominal pain. A routine abdominal CT is obtained which shows a small bowel obstruction. Also noted is a 2.4 cm right kidney lesion.
Most abdominal CT scans in the ED are done in a single portal venous phase, and it can be difficult to definitively characterize renal lesions. No longer! Spectral CT can make renal lesions really easy!
In this case, there is obvious iodine uptake in the kidney lesion, and the lesion shows >90 HU enhancement relative to the virtual non-contrast. All this can be done on PACS itself, without needing any fancy processing. The PACS screenshot below illustrates the point.
MRI confirmed the findings, but was likely superfluous. Patient will follow up to discuss options.
Spectral CT can help us get it right, the first time, and every time!
