A comparative trial of liver biopsy needles.
A sheathed needle (Tru-Cut) was compared with a suction biopsy needle (Menghini) in a randomised prospective trial over 18 months to determine whether the former offered any special advantages in routine percutaneous liver biopsy. Seventy-seven consecutive biopsies were performed by a single operator. Although biopsy fragmentation was commoner with the suction needle, the length and volume of t...
متن کاملComparison of the Trucut and Surecut liver biopsy needles.
The Trucut and Surecut liver biopsy needles have been compared in a prospective randomised study. Although the Surecut specimens were longer and heavier they tended to fragment during processing. Trucut specimens were subject to less artefact and were rated more highly by the histopathologist. However, the majority of biopsies obtained by both needles were satisfactory for diagnostic purposes.
متن کاملCurving Clinical Biopsy Needles: Can We Steer Needles and Still Obtain Core Biopsy Samples?1
Needle-based procedures, such as biopsy, thermal ablation, brachytherapy, and drug delivery, provide a minimally invasive means for diagnosis or treatment. The success of the procedure relies on the needle reaching the physician’s desired target (typically identified on a medical image) accurately. However, due to tissue deformation and the accuracy limits of human hand–eye coordination, the ne...

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 کاملPleural biopsy with Cope and Abrams needles.
The object of this study was to compare the diagnostic yield of Abrams and Cope needles. Pleural biopsies were performed in 24 patients with both needles. In two patients, the procedure was repeated within a few days. All patients had pleural effusion. The biopsies were performed at the same time; the biopsy sites were no more than 5 cm distant from each other. Diagnoses were exclusively pathol...
