Article Abstract
Background: Cell blocks (CB) are an established technique in non-gynecological cytology, but experience in gynecological cytology is still relatively limited. In this study, we compared the diagnostic agreement between liquid-based cytology (LBC) and CB using whole slide digital imaging (WSI).
Methods: WSI of 82 specimens (41 LBC and 41 CB) were evaluated independently by three observers.
Results: The overall agreement was 0.463 for all 82 cases including both LBC and CB, 0.439 for LBC alone, and 0.484 for CB alone. Agreement was highest for HSIL, NILM, cancers and lower for borderline (ASC-US, ASC-H). There was no significant difference in agreement between LBC and CB.
Conclusions: WSI of CB can be used for the diagnosis of cervical lesions and may be particularly useful in cases with high atypical cellularity or large hyperchromatic cell groups.

Large language models (LLMs) have been successfully used for data extraction from free-text radiology reports. Most current studies were conducted with LLMs accessed via an application programming interface (API). We evaluated the feasibility of using open-source LLMs, deployed on limited local hardware resources for data extraction from free-text mammography reports, using a common data element (CDE)-based structure.

Low-grade non-muscle invasive bladder cancer is a specific category of bladder cancer with a favourable prognosis; however, its management presents several challenges. The risk of stage progression is very low, but approximately half of patients will experience recurrence within the first 5 years after diagnosis. This high propensity for recurrence, coupled with the threat of progression, mandates ongoing surveillance.

Department of Orthopaedic Surgery, NHO Saga Hospital, 1-20-1 Hinode, Saga 849-0923, Japan.
Background: Hounsfield units (HU) on computed tomography (CT) are strongly correlated with bone mineral density (BMD) and may aid in osteoporosis screening. However, there is no standardized method for assessing bone density in displaced femoral head fractures. This study aimed to measure HU values in the femoral head using preoperative post-fracture CT images of patients with intertrochanteric femoral fractures and investigate whether it correlated with BMD measured by dual-energy X-ray absorptiometry (DXA).

Purpose: The ability to accurately detect and characterize intramammary micro- and macrocalcifications without ionized radiation has significant clinical implications for early breast cancer assessment. The aim of this prospective study was to investigate the feasibility of detecting intramammary calcifications using 3D multi-echo gradient echo (ME-GRE) magnitude and true susceptibility-weighted images (tSWI) compared to digital mammography (DM) in patients with different breast sizes and densities of breast parenchyma at 1.5T.
