Kidney lesion

Case Study
Philips CT Clinical Science Philips Healthcare • USA

Clinical history

An elderly patient was referred to Cliniques Universitaires Saint-Luc UCL from another hospital for a second opinion of a suspicious lesion in the right kidney. The technologist performed the scan on the IQon Spectral CT system. A multi-phase scan protocol included a non-enhanced CT, 60-second and 180-second post-injection phases.

Image scan parameters

  • 7.1 mGy CTDI
  • 193.8 mGy x cm
  • 0.1 mSv

Clinical significance

It was difficult to characterize whether it was a lesion or a cyst on conventional images because of similar Hounsfield Units across different phases. Because the patient was scanned on the IQon Spectral CT, which provides conventional and spectral data 100% of the time in a single scan, spectral data was also available for this case review. Spectral results confirmed the increased enhancement on the kidney lesion, as well as increased iodine uptake in the delayed scan. A follow-up CT scan was scheduled to confirm the diagnosis based on the increased suspicion from spectral results.

In oncology patients, the Philips IQon Spectral CT system can enhance diagnostic confidence by allowing complete (morphological and functional) assessment of lesions.
