Investigation of the value of ultrasound-guided core needle biopsy from pathologic lymph nodes to the diagnosis of lymphoma.

Introduction: In recent years, techniques with minimally invasive have been gradually developed and used in the diagnosis of lymphoma. Among minimally invasive techniques, core needle biopsy (CNB) has been widely accepted as an effective tool for the diagnosis of malignant lymphoma, carcinoma and deep tumors that are only accessible via CT or endoscopic-guided. This study was conducted to investigate of diagnostic value of ultrasound guided CNB in the diagnosis of lymphoma in all parts of the body compared to surgical excisional biopsy (SEB).
