Objectives: Grading of oral epithelial dysplasia (OED) has been plagued with intra-observer and inter-observer variations. To overcome this subjectivity, a more objective digital image analysis is obligatory using computer-aided software. The use of open-source software like QuPath, which is a new bio-image evaluation software program, may fulfil this growing need in virtual pathology. This study used the QuPath software for automatic analysis of morphometric parameters in hematoxylin and eosin (H and E)-stained digital images of oral epithelial dysplasia.
Methodology: 150 H and E digital images of varying grades of OED captured under 40x magnification were processed using QuPath software for automatic analysis of cellular and nuclear parameters.
Results: The parameters that showed statistical significance included nuclear hematoxylin OD, nuclear eosin OD, cellular hematoxylin OD, cellular eosin OD, cytoplasm hematoxylin OD, and cytoplasmic eosin OD ( < 0.05), while none of the other parameters showed statistically significant differences. A prediction accuracy of 76%, 74%, and 70% for mild, moderate, and severe dysplasia was obtained, respectively.
Conclusion: The quantitative results outlined in this paper are encouraging to indicate that the use of this technique may improve the diagnostic reliability of OED. Morphometric analysis of OED using Qupath software can be fast and reproducible and can be quantitated automatically.

The cervical uncinate process is a unique structure of the cervical spine that undergoes significant changes in its morphological characteristics with age, and these changes may be related to osteoporosis. This study aimed to observe the distribution of cancellous bone in the cervical uncinate process and its morphological features using micro-computed tomography (Micro-CT) to gain a deeper understanding of the morphological characteristics of the uncinate microstructure. We performed Micro-CT scans on 31 sets of C3-C7 vertebrae, a total of 155 intact bone samples, and subsequently used the measurement software with the Micro-CT system to obtain parameters related to the cancellous bone of the uncinate process.

Accurate diagnosis of pancreatic cancer using CT scan images is critical for early detection and treatment, potentially saving numerous lives globally. Manual identification of pancreatic tumors by radiologists is challenging and time-consuming due to the complex nature of CT scan images and variations in tumor shape, size, and location of the pancreatic tumor also make it challenging to detect and classify different types of tumors. Thus, to address this challenge we proposed a four-stage framework of computer-aided diagnosis systems.

Objectives: It is significant to know how much early detection and screening could reduce the proportion of occult metastases and benefit NSCLC patients.
Methods: We used previously designed and validated mathematical models to obtain the characteristics of LC in the population including undetectable metastases at the time of diagnosis. The survival was simulated using the survival functions from Surveillance, Epidemiology and End Results (SEER) data stratified by stage.

Articular malalignment and ulnocarpal impaction can progress to osteoarthritis in the wrist. This may be triggered by tears of the scapholunate ligament (rarely the lunotriquetral ligament) or the foveal lamina of the triangular fibrocartilage complex. In the pre-degenerative stages, radiographic findings are inconclusive, and symptoms may be absent or discrete.

Importance: The phase 3 randomized EMBARK trial evaluated enzalutamide with or without leuprolide in high-risk nonmetastatic hormone-sensitive prostate cancer. Eligibility relied on conventional imaging, which underdetects metastatic disease compared with prostate-specific membrane antigen-positron emission tomography (PSMA-PET).
Objective: To describe the staging information obtained by PSMA-PET/computed tomography (PSMA-PET/CT) in a patient cohort eligible for the EMBARK trial.
