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).
