Liver Biopsy by Needle
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...
متن کاملApplication of Raman spectroscopy to identify microcalcifications and underlying breast lesions at stereotactic core needle biopsy.
Microcalcifications are a feature of diagnostic significance on a mammogram and a target for stereotactic breast needle biopsy. Here, we report development of a Raman spectroscopy technique to simultaneously identify microcalcification status and diagnose the underlying breast lesion, in real-time, during stereotactic core needle biopsy procedures. Raman spectra were obtained ex vivo from 146 t...

Biopsies of thoracic lesions guidance. 22 of the 1 12 lesions were mediastinal and 83 were pleuroparenchymal. A large-bore 14-gauge Tru-cut needle was used in all patients. Adequate specimens for histologic examination were obtained in 98%. The overall accuracy was 91 % with 9% false negative and no false positive diagnoses. Despite the large size of the needle, the total number of complic...
متن کاملRetrieval Rate and Accuracy of Ultrasound-Guided 14-G Semi-Automated Core Needle Biopsy of Breast Microcalcifications
OBJECTIVE To evaluate the retrieval rate and accuracy of ultrasound (US)-guided 14-G semi-automated core needle biopsy (CNB) for microcalcifications in the breast. MATERIALS AND METHODS US-guided 14-G semi-automated CNB procedures and specimen radiography were performed for 33 cases of suspicious microcalcifications apparent on sonography. The accuracy of 14-G semi-automated CNB and radiology...
