From Fluoroscopy to Cross Sectional Guidance
Clinicians moved from fluoroscopic needle localization to cross sectional image guidance using CT and ultrasound which allowed precise percutaneous sampling of deep lesions and reduced morbidity compared with open surgical biopsy and these image guided techniques became standard for liver lung and renal sampling
Technique Standardization and Safety
Image guided biopsy required sterile technique needle selection and real time imaging confirmation and teams developed protocols for coagulation assessment and for post procedure monitoring to minimize complications and to ensure diagnostic yield
Impact on Oncology and Diagnosis
Percutaneous image guided biopsy transformed oncologic diagnosis staging and personalized therapy by enabling tissue diagnosis with lower risk and by facilitating molecular testing that guides targeted treatments
