Summary
Positron Emission Tomography-magnetic resonance (PET-MR) effectively detects prostate cancer bone metastases with 95% sensitivity. The SUVmax/ADCmin ratio shows the best diagnostic efficacy, aiding clinical evaluation.
Area of Science:
- Oncology
- Radiology
- Medical Imaging
Background:
- Prostate cancer (PC) bone metastases pose a diagnostic challenge.
- Positron Emission Tomography-magnetic resonance (PET-MR) offers high contrast imaging for PC diagnosis.
- This study evaluates PET-MR's effectiveness in detecting bone metastases.
Purpose of the Study:
- To assess the diagnostic performance of PET-MR for bone metastases in prostate cancer patients.
- To compare imaging findings with pathological confirmation.
- To identify imaging biomarkers for bone metastasis detection.
Main Methods:
- 212 prostate cancer patients underwent PET-MR imaging.
- Patients were categorized into bone metastasis (n=40) and non-metastasis (n=172) groups.
- Analysis included Gleason score, SUVmax, ADCmin, and ROC curves.
Main Results:
- PET-MR demonstrated 95% sensitivity and 79.72% specificity for bone metastasis detection.
- The SUVmax/ADCmin ratio showed the highest AUC (0.864).
- Elevated Gleason score, tPSA, ALP, SUVmax, and SUVmax/ADCmin were associated with metastasis.
Conclusions:
- PET-MR is a valuable tool for diagnosing prostate cancer bone metastases.
- SUVmax, ADCmin, and their ratio are significant indicators of bone metastasis.
- The SUVmax/ADCmin ratio exhibits superior diagnostic performance.
