Minimizing bias is critical to adoption and implementation of machine learning (ML) in clinical practice. Systematic mathematical biases produce consistent reproducible differences between the observed expected performance ML systems, resulting suboptimal performance. Such can be traced back various phases development: data handling, model development, evaluation. This report presents 12 practices during handling an study, explains how those lead biases, describes what may done mitigate...

There is a growing demand for high-resolution (HR) medical images both clinical and research applications. Image quality inevitably traded off with acquisition time, which in turn impacts patient comfort, examination costs, dose, motion-induced artifacts. For many image-based tasks, increasing the apparent spatial resolution perpendicular plane to produce multi-planar reformats or 3D commonly used. Single-image super-resolution (SR) promising technique provide HR based on deep learning...

There are increasing concerns about the bias and fairness of artificial intelligence (AI) models as they put into clinical practice. Among steps for implementing machine learning tools workflow, model development is an important stage where different types biases can occur. This report focuses on four aspects such may arise: data augmentation, loss function, optimizers, transfer learning. emphasizes appropriate considerations practices that mitigate in radiology AI studies.

The increasing use of machine learning (ML) algorithms in clinical settings raises concerns about bias ML models. Bias can arise at any step creation, including data handling, model development, and performance evaluation. Potential biases the be minimized by implementing these steps correctly. This report focuses on evaluation discusses fitness, as well a set toolboxes: namely, metrics, interpretation maps, uncertainty quantification. By discussing strengths limitations each toolbox, our...

Background Multiparametric MRI can help identify clinically significant prostate cancer (csPCa) (Gleason score ≥7) but is limited by reader experience and interobserver variability. In contrast, deep learning (DL) produces deterministic outputs. Purpose To develop a DL model to predict the presence of csPCa using patient-level labels without information about tumor location compare its performance with that radiologists. Materials Methods Data from patients known who underwent January 2017...

Background: Establishing imaging registries for large patient cohorts is challenging because manual labeling tedious and relying solely on DICOM (digital communications in medicine) metadata can result errors. We endeavored to establish an automated hip pelvic radiography registry of total arthroplasty (THA) patients by utilizing deep-learning pipelines. The aims the study were (1) utilize these pipelines identify all radiographs with appropriate annotation laterality presence or absence...

To develop a deep learning model that segments intracranial structures on head CT scans.In this retrospective study, primary dataset containing 62 normal noncontrast scans from patients (mean age, 73 years; age range, 27-95 years) acquired between August and December 2018 was used for development. Eleven were manually annotated the axial oblique series. The split into 40 training, 10 validation, 12 testing. After initial eight configurations evaluated validation highest performing test...

Radiographic markers contain protected health information that must be removed before public release. This work presents a deep learning algorithm localizes radiographic and selectively removes them to enable de-identified data sharing. The authors annotated 2000 hip pelvic radiographs train an object detection computer vision model. Data were split into training, validation, test sets at the patient level. Extracted then characterized using image processing algorithm, potentially useful...

Dislocation is the most common reason for early revision following total hip arthroplasty (THA). More than 40 years ago, Lewinnek et al. proposed an acetabular "safe zone" to avoid dislocation. While novel at time, their study was substantially limited according modern standards. The purpose of this determine optimal cup positioning during THA as well effect surgical approach on topography safe zone and hazard dislocation.Primary THAs that had been performed a single institution from 2000...
