Prospective Study for Comparison of Endoscopic Ultrasound-Guided Tissue Acquisition Using 25- and 22-Gauge Core Biopsy Needles in Solid Pancreatic Masses. [PDF]

PLoS ONE, 2016
BACKGROUND AND AIMS:Although thicker needles theoretically allow more tissue to be collected, their decreased flexibility can cause mechanical damage to the endoscope, technical failure, and sample blood contamination.

Diagnostic yield of percutaneous computed tomography guided core needle biopsy of lung lesion and its complications in tertiary hospital [PDF]

, 2020
Background: Early diagnosis of lung cancer can reduce its mortality and morbidity. Minimally invasive image guided percutaneous core needle biopsy can obtain tissue sample for diagnosis and staging of lung cancer, which is crucial for correct management ...

Core needle biopsy versus incisional biopsy for differentiation of soft‐tissue sarcomas: A systematic review and meta‐analysis

Cancer, 2020
Controversies exist regarding the biopsy technique of choice for the accurate diagnosis of soft‐tissue sarcoma (STS). The objective of this systematic review and meta‐analysis was to compare the diagnostic accuracy of core needle biopsy (CNB) versus ...

Long‐term prognosis is associated with residual disease after neoadjuvant systemic therapy but not with initial nodal status

BJS (British Journal of Surgery), EarlyView., 2020
This long‐term follow‐up study determined survival rates in a Swedish national cohort of 417 patients with breast cancer who all had neoadjuvant systemic therapy (NAST). Sentinel lymph node biopsy (SLNB) was performed before NAST in clinically node‐negative and after NAST in clinically node‐positive patients.

A challenging case of Mesenchymal Chondrosarcoma involving the thyroid and special considerations for diagnosis

Clinical Diabetes and Endocrinology, 2020
Background Thyroid ultrasound is usually used to risk-stratify incidental thyroid nodules. Nodules with high risk sonographic features for malignancy are evaluated by fine-needle aspiration.

Strategising template-guided needle placement for MR-targeted prostate biopsy [PDF]

arXiv, 2022
Clinically significant prostate cancer has a better chance to be sampled during ultrasound-guided biopsy procedures, if suspected lesions found in pre-operative magnetic resonance (MR) images are used as targets. However, the diagnostic accuracy of the biopsy procedure is limited by the operator-dependent skills and experience in sampling the targets ...

2019 Practice guidelines for thyroid core needle biopsy: a report of the Clinical Practice Guidelines Development Committee of the Korean Thyroid Association

Journal of Pathology and Translational Medicine, 2020
Ultrasound-guided core needle biopsy (CNB) has been increasingly used for the pre-operative diagnosis of thyroid nodules. Since the Korean Society of the Thyroid Radiology published the ‘Consensus Statement and Recommendations for Thyroid CNB’ in 2017 ...

TRUSformer: Improving Prostate Cancer Detection from Micro-Ultrasound Using Attention and Self-Supervision [PDF]

arXiv, 2023
A large body of previous machine learning methods for ultrasound-based prostate cancer detection classify small regions of interest (ROIs) of ultrasound signals that lie within a larger needle trace corresponding to a prostate tissue biopsy (called biopsy core).

Synthesizing Strategies for Needle Steering in Gelatin Phantoms [PDF]

EPTCS 316, 2020, pp. 261-274, 2020
In medicine, needles are frequently used to deliver treatments to subsurface targets or to take tissue samples from the inside of an organ. Current clinical practice is to insert needles under image guidance or haptic feedback, although that may involve reinsertions and adjustments since the needle and its interaction with the tissue during insertion ...
