Ultrasound-Guided Trans-Uterine Cavity Core Needle Biopsy of Uterine Myometrial Tumors to Differentiate Sarcoma from a Benign Lesion—Description of the Method and Review of the Literature

open access: yesDiagnostics, 2022
Uterine sarcomas are rare, aggressive tumors with poor prognosis that can be further negatively affected by inadequate surgical approaches such as morcellation.

World Health Organization (WHO)/International Society of Urological Pathology (ISUP) grading in fine‐needle aspiration biopsies of renal masses [PDF]

open access: yes, 2018
Background Utilization of fine‐needle aspiration (FNA) biopsy for the evaluation of renal masses has been increasing at our institution. At times diagnostic material on direct smears is superior to that in the cell block/core biopsy, therefore assigning

Ultrasonic Actuation of a Fine-Needle Improves Biopsy Yield [PDF]

open access: yesarXiv, 2020
Despite the ubiquitous use over the past 150 years, the functions of the current medical needle are facilitated only by mechanical shear and cutting by the needle tip,i.e.the lancet. In this study, we demonstrate how nonlinear ultrasonics (NLU) extends the functionality of the medical needle far beyond its present capability. The NLU actions were found

EUS-Guided Biopsy with a Novel Puncture Biopsy Forceps Needle—Feasibility Study

open access: yesDiagnostics, 2021
Endoscopic ultrasound (EUS) with fine needle aspiration (FNA) or biopsy (FNB) to diagnose lesions in the gastrointestinal tract is common. Demand for histology sampling to identify treatment-specific targets is increasing. Various core biopsy FNB needles

Comparison of Thyroid Fine-Needle Aspiration and Core Needle Biopsy [PDF]

open access: yesAmerican Journal of Clinical Pathology, 2007
We compared the adequacy and accuracy of fineneedle aspiration (FNA) with core needle aspiration in a total of 377 patients who underwent both tests. The adequacy rate for core needle biopsy (82.2%) was significantly higher than that of FNA (70.3%; P < .001), but the combined adequacy was significantly higher than that for either test alone (88.9%; P <

Prostate biopsies guided by three-dimensional real-time (4-D) transrectal ultrasonography on a phantom: comparative study versus two-dimensional transrectal ultrasound-guided biopsies [PDF]

open access: yesEuropean Urology 52, 4 (2007) 1097-104, 2007
OBJECTIVE: This study evaluated the accuracy in localisation and distribution of real-time three-dimensional (4-D) ultrasound-guided biopsies on a prostate phantom. METHODS: A prostate phantom was created. A three-dimensional real-time ultrasound system with a 5.9MHz probe was used, making it possible to see several reconstructed orthogonal viewing ...

A Pathologist-Informed Workflow for Classification of Prostate Glands in Histopathology [PDF]

open access: yesFirst International Workshop, MOVI 2022, Held in Conjunction with MICCAI 2022, Singapore, September 18, 2022, Proceedings, https://link.springer.com/book/10.1007/978-3-031-16961-8, 2022
Pathologists diagnose and grade prostate cancer by examining tissue from needle biopsies on glass slides. The cancer's severity and risk of metastasis are determined by the Gleason grade, a score based on the organization and morphology of prostate cancer glands.

Avoidable and Unavoidable Repeat Breast Core Needle Biopsies [PDF]

open access: yes, 2022
Background: Breast core needle biopsies are not perfect and could miss cancer. The need for a repeat breast core biopsy is not uncommon and can occur for a multitude of reasons.

Diffusion-weighted MRI-guided needle biopsies permit quantitative tumor heterogeneity assessment and cell load estimation [PDF]

open access: yesarXiv, 2021
Quantitative information on tumor heterogeneity and cell load could assist in designing effective and refined personalized treatment strategies. It was recently shown by us that such information can be inferred from the diffusion parameter D derived from the diffusion-weighted MRI (DWI) if a relation between D and cell density can be established ...
