A palpable lump, a suspicious thyroid nodule on scan, an enlarged lymph node, or a breast mass seen on mammography — all of these require tissue sampling for definitive diagnosis. The USG Guided FNAC and Biopsy service at Neurad Diagnostics in Delhi provides the most direct, safe, and accurate route to tissue diagnosis for superficial and ultrasound-visible lesions. Using real-time high-resolution ultrasound to guide needle placement with pinpoint precision, our experienced team delivers highly accurate tissue samples while minimizing patient discomfort and risk. This comprehensive guide explains everything about this procedure and Biopsy in Delhi. According to the American College of Radiology (ACR), ultrasound-guided FNAC and biopsy are the recommended standard for sampling thyroid nodules, lymph nodes, and superficial masses. The American Thyroid Association (ATA) guidelines specifically recommend ultrasound-guided FNAC for all thyroid nodules meeting biopsy criteria. ultrasound guided biopsy at Neurad Diagnostics Delhi — Real-time ultrasound-guided tissue sampling Table of Contents What Is USG Guided FNAC and Biopsy?

Conclusion — Book Your USG Guided FNAC / Biopsy at Neurad Diagnostics Delhi What Is USG Guided FNAC and Biopsy? this test (Ultrasound Guided Fine Needle Aspiration Cytology) and USG Guided Core Needle Biopsy are interventional procedures that use real-time ultrasound imaging to precisely guide a needle to a target lesion for tissue sampling. Ultrasound guidance allows the radiologist to see the needle tip in real time as it approaches the target lesion, ensuring accurate sampling while avoiding blood vessels and critical structures. Compared to CT guidance, ultrasound guidance has the advantage of being completely radiation-free, more cost-effective, and highly efficient for superficial or intra-abdominal lesions that are well-visualized on ultrasound. It is the guidance method of choice for thyroid nodules, lymph nodes, breast masses, liver lesions, and other superficial/ultrasound-visible structures. At Neurad Diagnostics in Delhi, USG guided procedures are performed by highly experienced interventional radiologists using state-of-the-art high-resolution ultrasound systems. USG Guided FNAC vs. Core Needle Biopsy Understanding the difference between these two procedures helps patients and physicians choose the right approach: the FNAC: Uses a very thin needle (22-25 gauge, the size of a standard blood draw needle) to aspirate a small number of cells from the lesion. This is a cytological procedure — the aspirated cells are spread on glass slides and examined by a cytopathologist. FNAC is very quick, minimally invasive, requires no anaesthesia (or minimal local anaesthesia), and has an excellent safety profile. It is ideal for thyroid nodules, superficial lymph nodes, parotid gland, breast masses (especially cysts), and soft tissue lesions. The main limitation is that it provides only cellular material, which may be insufficient for diagnoses requiring tissue architecture assessment or extensive molecular profiling. USG Guided Core Needle Biopsy (CNB): Uses a spring-loaded cutting needle (14-20 gauge) to obtain a small core of tissue that preserves the architecture of the lesion. This is a histopathological procedure — the tissue core is processed, sectioned, and stained for examination. CNB provides material suitable for IHC, receptor profiling (ER/PR/HER2 for breast), molecular mutation testing (EGFR, ALK for lung), and lymphoma subtyping. It requires local anaesthesia but is still an outpatient, day-care procedure. CNB is preferred for breast cancer (ER/PR/HER2 profiling), liver biopsies, lymphoma, and any situation requiring molecular characterization. Why Doctors Recommend USG Guided FNAC and Biopsy Endocrinologists, oncologists, surgeons, and other specialists recommend the procedure and Biopsy in Delhi because ultrasound guidance transforms what would otherwise be a blind or inaccurate sampling attempt into a precise, visualized, and reliable procedure. For thyroid nodules specifically, blind aspiration carries a significantly higher inadequate sample rate than ultrasound guided FNAC — which has become the universal standard of care. For breast lesions, ultrasound guided core biopsy has replaced most open surgical biopsies, reducing patient morbidity dramatically. In modern oncology, the shift toward precision medicine means that tissue diagnosis must provide not just a cancer confirmation but a complete molecular characterization — receptor status, mutation profile, PD-L1 expression — to guide targeted therapy selection. Ultrasound guided core needle biopsy provides the high-quality tissue samples necessary for this comprehensive molecular testing at Neurad Diagnostics in Delhi.
