Image Guided Biopsy

Biopsy Needles are sterile, single-use precision medical devices designed to obtain tissue or cellular specimens from internal organs, masses, and lesions for histopathological or cytological diagnosis. Available in core biopsy (automatic spring-loaded, semi-automatic, vacuum-assisted, coaxial) and fine needle aspiration configurations, with gauges ranging from 14G-27G and lengths from 6-25 cm. Core biopsy needles obtain intact tissue cores preserving histological architecture; FNA needles aspirate cellular material for cytological evaluation. Specialized variants include bone marrow biopsy needles (Jamshidi, Illinois), echogenic-tip needles for ultrasound guidance, and MRI-compatible needles (nitinol, titanium). Critical safety requirements include strict image guidance for non-palpable lesions, verification of coagulation status, adherence to single-use protocols, and immediate post-procedure monitoring for complications (hemorrhage, pneumothorax, organ injury). An indispensable tool in interventional radiology, oncology, and minimally invasive diagnosis.
