Ultrasonic actuation of a fine-needle improves biopsy yield [PDF]
, 2021 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

Fine-needle aspiration biopsy of the liver [PDF]
American Journal of Roentgenology, 1980 Percutaneous fine-needle aspiration biopsy of focal liver lesions was performed in 36 patients. Of the biopsies, 83% yielded enough cytologic material for a correct diagnosis, without significant complications. The primary indication for the biopsy was to document the presence of malignancy and avoid a diagnostic laparotomy.

Low‐field MRI: Clinical promise and challenges
Journal of Magnetic Resonance Imaging, Volume 57, Issue 1, Page 25-44, January 2023., 2023 Modern MRI scanners have trended toward higher field strengths to maximize signal and resolution while minimizing scan time. However, high‐field devices remain expensive to install and operate, making them scarce outside of high‐income countries and major population centers.

SlicerPET: A workflow based software module for PET/CT guided needle biopsy [PDF]
, 2015 Biopsy is commonly used to confirm cancer diagnosis when radiologically indicated. Given the ability of PET to localize malignancies in heterogeneous tumors and tumors that do not have a CT correlate, PET/CT guided biopsy may improve the diagnostic yield of biopsies.

Personalized Biopsy Schedules Using an Interval-censored Cause-specific Joint Model [PDF]
arXiv, 2022 Active surveillance (AS), where biopsies are conducted to detect cancer progression, has been acknowledged as an efficient way to reduce the overtreatment of prostate cancer. Most AS cohorts use fixed biopsy schedules for all patients. However, the ideal test frequency remains unknown, and the routine use of such invasive tests burdens the patients. An
