Multimodal planning of vacuum-assisted fine-needle aspiration biopsy for focal liver lesions: A single-center comparative diagnostic study
Background: Morphological verification of indeterminate liver lesions is essential to confirm metastasis and guide treatment. The diagnostic yield of standard fine-needle aspiration biopsy (FNAB) depends on suction stability and the choice of target zone. Vacuum-assisted FNAB (v-FNAB) provides controlled negative press...
