*Causes of Mistargeting during Liver Ablation*
Poor tumor conspicuity on imaging (e.g., isoechoic or poorly visible tumors on ultrasound)
Inaccurate image registration or fusion imaging errors
Respiratory motion and inadequate breath control
Patient movement during the procedure
Suboptimal patient positioning
Anatomical distortion due to prior surgery or treatment
Presence of multiple lesions causing confusion in lesion identification
Incorrect interpretation of pre-procedural imaging
Inadequate planning of the electrode trajectory
Limited acoustic window or obscuration by ribs, lung, or bowel gas
Operator inexperience or technical error
Deformation of the liver during electrode insertion
Failure to correlate real-time imaging with pre-procedural images
Tumor margin misinterpretation or satellite lesions not recognized
