Biopsy Needles(活检针)研究综述
Biopsy Needles 活检针 - MR imaging data acquired from several phantoms containing interventional devices such as biopsy needles, stent, and brachytherapy seeds, used for validating the proposed technique. [1] The presented technique minimizes the risk of infectious complications by eliminating the need for biopsy needles to pass through the rectal mucosa. [2] The quality of the specimens obtained, using two different types of biopsy needles, was assessed microscopically. [3] Biopsy needles are standard medical devices for extracting biological tissue with the purpose of diagnosing a specific anomaly such as cancerous masses, or lumps. [4] For a given prostate volume and number of biopsy needles, our rule is to treat if total length of cancer in needle cores exceeds c, the cutoff value, with active surveillance otherwise, provided pathology is favorable. [5] Background: To overcome the limitations of using cytological specimen alone for the diagnosis of challenging pancreatic lesions, biopsy needles have been developed to procure histological specimens during EUS, especially for the discrimination of several specific pancreatic tumors requiring adequate histological samples. [6] Biopsy needles with embedded force sensors can eliminate the needle deflection and the needle targeting failure risks during MRI guided biopsy procedures. [7] Duchenne’s trocar was a forerunner of several types of modern muscle-biopsy needles. [8] Recent studies have reported that EUS-guided LB may have a better safety profile than PC LB or TJ LB without compromising diagnostic yield, and the outcomes are varied with respect to the types of biopsy needles. [9]从包含介入设备(例如活检针、支架和近距离放射治疗种子)的多个模型中获取的 MR 成像数据,用于验证所提出的技术。 [1] 所提出的技术通过消除活检针穿过直肠黏膜的需要,最大限度地降低了感染并发症的风险。 [2] 使用两种不同类型的活检针获得的标本质量在显微镜下进行评估。 [3] 活检针是用于提取生物组织的标准医疗设备,目的是诊断特定异常,例如癌性肿块或肿块。 [4] 对于给定的前列腺体积和活检针数,我们的规则是如果针芯中的癌症总长度超过 c(截止值),则进行治疗,否则进行主动监测,前提是病理学是有利的。 [5] 背景:为了克服单独使用细胞学标本诊断具有挑战性的胰腺病变的局限性,活检针已被开发用于在 EUS 期间获取组织学标本,特别是用于区分需要足够组织学样本的几种特定胰腺肿瘤。 [6] 带有嵌入式力传感器的活检针可以消除 MRI 引导活检过程中的针偏转和针定位失败风险。 [7] Duchenne 的套管针是几种现代肌肉活检针的先驱。 [8] 最近的研究报告称,EUS 引导的 LB 可能比 PC LB 或 TJ LB 具有更好的安全性,而不会影响诊断率,并且结果因活检针的类型而异。 [9]
fine needle biopsy
Background and Objective: EUS-guided fine-needle biopsy (EUS-FNB) with acquisition of tissue core is possible with the use of 19G fine-needle aspiration (FNA) and dedicated biopsy needles. [1] Background Various core biopsy needles have previously been developed for endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB). [2] In recent years, a new generation of biopsy needles (EUSFNB [fine-needle biopsy]) has been developed for acquisition of whole tissue samples [13–15]. [3]背景和目的:通过使用 19G 细针抽吸 (FNA) 和专用活检针,可以获得组织核心的 EUS 引导下的细针活检 (EUS-FNB)。 [1] 背景 先前已经开发了各种芯活检针用于内窥镜超声引导的细针活检 (EUS-FNB)。 [2] nan [3]
Core Biopsy Needles 核心活检针
EUS offers advantages of real-time, image-guided targeting of lesions and use of Pro core biopsy needles, which improves tissue yield while avoiding fluoroscopy. [1] To compare clinical efficacy, subjective radiologist preference, and complication rates for two different core biopsy needles, the Achieve® and Marquee®. [2] Here, we compared the efficacy between 16- and 18-gauge core biopsy needles in US-guided percutaneous transthoracic biopsy for PPLs on histological diagnosis and procedure-related complications. [3] Core biopsy needles are designed to collect a small piece of tissue intended for surgical pathology analysis and can be designed as end-cutting or side-cutting devices. [4] Human kidney biopsy specimens (545 CNB from 102 patients, 5583 spectra for analysis) were analyzed directly on core biopsy needles with a custom-built optical spectroscopy instrument. [5] Background Various core biopsy needles have previously been developed for endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB). [6] Methods This prospective, observational pilot study undertook sampling of brain, lung, and liver tissue using core biopsy needles, blood and cerebrospinal fluid collection, and placental examination. [7]EUS 具有实时、图像引导的病灶定位和 Pro core 活检针的使用优势,可提高组织产量,同时避免透视。 [1] 比较两种不同的核心活检针,Achieve® 和 Marquee® 的临床疗效、主观放射科医生偏好和并发症发生率。 [2] nan [3] nan [4] 使用定制的光谱仪直接在核心活检针上分析人肾活检标本(来自 102 名患者的 545 个 CNB,用于分析的 5583 个光谱)。 [5] 背景 先前已经开发了各种芯活检针用于内窥镜超声引导的细针活检 (EUS-FNB)。 [6] nan [7]
Needle Biopsy Needles 针活检针
EUS-FNA was performed using fine-needle aspiration needles, and EUS-FNB was performed using fine-needle biopsy needles. [1] Recently, several fine-needle biopsy needles are commercially available for endoscopic ultrasound-guided tissue acquisition. [2] Fine needle biopsy needles procure more histologic-grade tissue compared to aspiration needles and may be preferable in the case of solid pancreatic lesions in an era of precision medicine. [3] The aim of this meta-analysis was to provide a pooled estimate of the diagnostic performance and safety profile of Franseen and Fork-tip fine-needle biopsy needles. [4]EUS-FNA 使用细针穿刺针进行,EUS-FNB 使用细针活检针进行。 [1] 最近,一些细针活检针可用于内窥镜超声引导的组织采集。 [2] nan [3] nan [4]
Gauge Biopsy Needles
Tissue acquisition was done with 19- or 22-gauge biopsy needles. [1] The use of 20-gauge biopsy needles and obtaining ≥ 3 samples may be recommended to improve diagnostic outcomes and decrease complication rates. [2]组织采集是用 19 或 22 号活检针完成的。 [1] nan [2]
Cut Biopsy Needles
The Tru-cut biopsy was performed by using 14 gauge disposable Tru-cut biopsy needles (Baxter, made in the USA) by means of two successive insertions with different angulations of the needle into the core of the lesion followed by incisional biopsy. [1] Liver function test with Liver biopsy was performed under ultrasound guidance from right liver lobe, under local xylocaine 2% injection with using 16 gauge co-axial automatic True cut biopsy needles Results: A total of 62 patients had been included in this study, 38 (61. [2]使用 14 号一次性 Tru-cut 活检针(Baxter,美国制造)进行 Tru-cut 活检,方法是通过两次以不同角度将针连续插入病变核心,然后进行切口活检。 [1] nan [2]
Generation Biopsy Needles
The original Trucut biopsy needle had been cumbersome to use, but the recent introduction of newer‐generation biopsy needles has transformed the landscape, such that there is now a greater focus on tissue acquisition for histological assessment. [1] New-generation biopsy needles provide higher histology rates and require less passes. [2]最初的 Trucut 活检针使用起来很麻烦,但最近引入的新一代活检针已经改变了格局,因此现在更加关注组织学评估的组织采集。 [1] nan [2]
biopsy needles provide
Modified Menghini type semi‐automatic aspiration biopsy needles provide small tissue fragments (STFs), as well as cellular smears, and immunohistochemical and molecular studies can be performed using the STFs. [1] New-generation biopsy needles provide higher histology rates and require less passes. [2]改良的 Menghini 型半自动抽吸活检针提供小组织碎片 (STF) 以及细胞涂片,并且可以使用 STF 进行免疫组织化学和分子研究。 [1] nan [2]
