• Correct applicator size for electron, superficial or electronic brachytherapy treatment ( ~50% changes applicator size) • Margin size evaluation • Fine-needle aspiration biopsy (FNAB) with ultrasound guidance – good correlation with histology results, specifity 98%,CT 76%,MRI 63% • Monitoring treatment results • Ultrasound limits of depth of evaluation (bone, air)
