image-guided biopsy
A minimally invasive procedure using imaging guidance to obtain tissue samples from suspicious lesions identified during cancer screening.
Full Definition
A diagnostic procedure that uses real-time imaging modalities such as ultrasound, mammography, MRI, or CT to guide needle placement for tissue sampling of suspicious lesions. This technique allows precise targeting of abnormalities that may not be palpable or easily accessible, making it essential for investigating findings detected through cancer screening programs. Image-guided biopsies provide definitive histopathological diagnosis while minimizing patient discomfort and avoiding the need for surgical biopsy in many cases. Different imaging modalities are selected based on lesion characteristics, visibility, and accessibility.
Usage
Usage note: Hyphenate when used as a compound modifier; specify imaging modality when relevant.
