To analyze the accuracy and safety of frameless stereotactic biopsies using MRI-only and MRI-CT fusion navigation, emphasizing the importance of histopathological confirmation for treatment planning.
Key Findings:
Frameless stereotactic biopsies demonstrated comparable accuracy and complication rates between MRI-only and MRI-CT fusion navigation, highlighting the need for careful technique selection based on clinical scenarios.
Lesion volume and biopsy trajectory significantly influenced diagnostic yield.
MRI guidance may be affected by geometric distortions, which can be mitigated by CT fusion.
Interpretation:
The study suggests that both MRI-only and MRI-CT fusion navigation are effective for frameless stereotactic biopsies, with the choice depending on specific clinical scenarios and the potential impact on patient outcomes.
Limitations:
Non-randomized group allocation may introduce bias, potentially affecting the reliability of the findings.
Limited data on direct comparisons between MRI-only and MRI-CT fusion navigation in larger cohorts.
Conclusion:
Frameless stereotactic biopsy using either navigation technique is safe and accurate, with MRI-CT fusion potentially offering advantages in specific cases, underscoring the need for tailored approaches in clinical practice.
