Design of an Endoscopic Biopsy Needle With Flexural Members
As a minimally invasive means of extracting a tissue sample from a patient, current endoscopic biopsy needles generally do not preserve tissue histology and often require multiple attempts to obtain a tissue sample. This paper presents an endoscopic biopsy needle with internal flexures that enables tissue to enter the hollow needle and then be severed from the surrounding tissue when the needle...
متن کاملEndoscopic Ultrasound-Guided Fine-Needle Aspiration Vs Fine-Needle Biopsy.
RM The primary goal of fine-needle aspiration is to acquire individual cells as opposed to tissue, which is the aim of fine-needle biopsy. Cells may not necessarily provide the stroma, or the associated architecture, of the surrounding tissue. Thus, if the surrounding architecture is needed to make a diagnosis, a fine-needle biopsy, which typically uses a core biopsy needle, should provide that.

در نمونه برداری سوزنی کبد یا آسپیراسیون کبد، توسط سوزن نمونه برداری می توان نمونه ای از بافت کبدی را جهت تشخیص اکثر اختلالات کبدی، اثبات وجود سرطان کبد، یا ارزیابی اثرات داروهای آسیب رساننده به کبد تهیه کرد. همچنین با انجام نمونه برداری های مکرر روند پیشرفت و پاسخ بیماران به درمان بیماری های کبدی مزمنی چون هپاتیت فعال را می توان مشخص نمود.
متن کاملConcordance Rate between Fine Needle Aspiration Biopsy and Core Needle Biopsy in Breast Lesions
Background and Objectives:Breast cancer is the most common cancer among women worldwide. Fine needle aspiration biopsy (FNAB) is one of the methods of breast biopsy which is fast, easy and cost effective. The aim of this study was to evaluate the concordance rate between pathologic results of sonography or stereotaxy guided FNAB and guided core needle biopsy (CNB) in the evaluation of breast le...
