Needle core biopsy of mammographic lesions. [PDF]

American Journal of Roentgenology, 1994
Needle core biopsy and fine-needle aspiration cytology (FNAC) provide histologic diagnoses in a wide variety of clinical settings. In breast disease, surgeons have used these techniques to evaluate palpable masses for many years. In recent years, radiologists have used image-guided adaptations of these two techniques to evaluate mammographically ...

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).

Breast pseudoaneurysm in a woman after core biopsy: Intravascular glue embolization

Journal of Medical Ultrasound, 2023
Core needle biopsy of breast masses is a common procedure for tissue diagnosis of breast lesions. The incidence of complications is low, with pseudoaneurysm (PA) after core biopsy has been described in the literature, and the subsequent need for surgical

Combination of needle aspiration and core needle biopsy: A new technique of stereotactic biopsy

Asian Journal of Neurosurgery, 2016
Aim: The study aims at describing the results of using a new technique to acquire the tissue sample in stereotactic biopsy of brain lesions. Materials and Methods: The study was performed in 19 patients over a period of 5 years in which we used the new technique, i.e., Abrar and Afzal technique (AT) of obtaining tissue biopsy.

Collaborative Robotic Biopsy with Trajectory Guidance and Needle Tip Force Feedback [PDF]

2023 IEEE International Conference on Robotics and Automation (ICRA), London, United Kingdom, 2023, pp. 6893-6900, 2023
The diagnostic value of biopsies is highly dependent on the placement of needles. Robotic trajectory guidance has been shown to improve needle positioning, but feedback for real-time navigation is limited. Haptic display of needle tip forces can provide rich feedback for needle navigation by enabling localization of tissue structures along the ...

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 ...

Postoperative and Recurrent Hematuria after Pretransplant Core Needle Biopsy in Living Donor Kidney Transplant

Case Reports in Transplantation, 2022
Background. Core needle and wedge biopsies are the two main pathologic ways to determine the suitability of a kidney allograft and to have a baseline allograft biopsy in case of future rejection. Case Presentation. A 57-year-old patient developed a renal

The diagnostic value of ultrasound-guided percutaneous core needle biopsy of musculoskeletal soft tissue lesions

Journal of Ultrasonography, 2021
Introduction: Percutaneous ultrasound-guided core needle biopsy is a well-established method in the diagnosis of musculoskeletal tumors. It is unclear which factors contribute the most to a successful biopsy.
