Hypothesis

Can delayed phase FDG-PET/CT imaging improve the detection of lesions in patients with primary and metastatic liver disease compared to traditional imaging methods?

Conclusion

Delayed phase FDG-PET/CT improved lesion detectability in primary and metastatic liver disease, revealing new lesions in 17% of the patients.

Supporting Evidence

  • Delayed phase FDG-PET/CT identified new lesions in 5 of the 30 patients.
  • It revealed extrahepatic sites of metastases not appreciated on CECT in 6 patients.
  • There was a significant increase in SUV value of liver lesions between early and delayed acquisition.

Takeaway

Using a special type of scan called delayed phase FDG-PET/CT helps doctors find more cancer spots in the liver that they might miss with regular scans.

Methodology

30 patients underwent delayed phase FDG-PET/CT imaging, and results were compared to triple-phase contrast enhanced CT (CECT).

Limitations

The study was limited to a small sample size of 30 patients.

Participant Demographics

30 patients (13 males and 17 females, mean age 61.1 years, age range 42–86 years).
