Despite the use of advanced radiological investigations, some liver lesions cannot be definitely diagnosed without a biopsy and histological examination. Laparoscopic Tru-Cut biopsy of the liver lesion is the preferred approach to achieve a good sample for histology. The mechanism of a Tru-Cut biopsy needle needs the use of both hands to load and fire the needle. This restricts the ability of t...
and nonpalpable breast lesions is a safe and effective alternative to fine-needle aspiration and needle-localized breast excisional biopsies (1, 2). It can reduce the need for a two-stage procedure and can improve the surgical and oncological outcomes (3). However, one disadvantage of this technique for sampling breast cancer is the possible seeding of malignant tumor cells along the needle tra...
BACKGROUND The authors evaluated outcomes and treatment costs of stereotactic core needle biopsy (SCNB) and ultrasound core needle biopsy (UCNB), and needle localization biopsy (NLB) in managing patients with mammographic abnormalities presenting to the surgeon. METHODS Data for all patients with mammographic lesions who underwent SCNB or UCNB since their introduction at this institution were...
We describe a side-firing fiber optic sensor based on near-infrared spectroscopy for guiding core needle biopsy diagnosis of breast cancer. The sensor is composed of three side firing optical fibers (two source fibers and one detection fiber), providing two source-detector separations. The entire assembly is inserted into a core biopsy needle, allowing for sampling to occur at the biopsy site. ...
