Hypothesis
Can SPECT/CT accurately measure vascularized liver volume for treatment planning in patients with complex hepatic vascularization?
Conclusion
SPECT/CT is an accurate method for measuring vascularized liver volume, which significantly aids in treatment planning for patients with complex liver anatomy.
Supporting Evidence
- SPECT/CT volume measurements had a mean error of less than 6% for volumes greater than 16 cm3.
- Interobserver agreement for SPECT/CT was high at 0.9.
- SPECT/CT identified a larger vascularized liver volume compared to traditional angiography.
Takeaway
Doctors used a special imaging technique called SPECT/CT to see how much of the liver was getting blood, which helped them plan better treatment for a patient with liver cancer.
Methodology
The study involved a phantom study and a case report where SPECT/CT was used to measure liver volumes and dosimetry.
Potential Biases
Potential bias from operator variability in volume measurements.
Limitations
The study primarily focused on a single case and phantom measurements, which may not fully represent all patient scenarios.
Participant Demographics
One 63-year-old patient with hepatocellular carcinoma.
