To buy or not to buy—evaluating commercial AI solutions in radiology (the ECLAIR guidelines)

Artificial intelligence (AI) has certainly made impressive progress over the past few years. Consequently, many companies have entered the market bombarding radiologists with diagnostic AI tools aiming to help them in their clinical practice. Navigating through this plethora of AI product offerings can be quite challenging at times. How do you know if the marketing claims could hold up in

Development of MR-based preoperative nomograms predicting DNA copy number subtype in lower grade gliomas with prognostic implication

The aim of this study was to determine the value of MR-based preoperative nomograms in predicting DNA copy number (CN) subtype in patients with lower grade glioma (LGG). The authors achieved this by retrospectively analyzing the overall survival (OS) data of 170 subjects. They found that the shortest OS was observed in patients with CN2 subtype. This preliminary radiogenomics analysis

Noise reduction approach in pediatric abdominal CT combining deep learning and dual-energy technique

The authors of this study aimed to evaluate the image quality of low iodine concentration, dual-energy CT (DECT) combined with a deep learning-based noise reduction technique for pediatric abdominal CT, compared with standard iodine concentration single-energy polychromatic CT (SECT). They were able to determine that low iodine concentration DECT, when combined with deep learning in pediatric abdominal CT, can maintain

Combining radiomics with ultrasound-based risk stratification systems for thyroid nodules: an approach for improving performance

In this study, the authors develop a radiomics score using ultrasound images in order to predict thyroid malignancy and to investigate its potential as a complementary tool to improve the performance of risk stratification systems. They found that radiomics was able to help predict malignancy in thyroid nodules in combination with risk stratification systems by improving specificity, accuracy, positive predictive

Bridging the chasm: Education may turn Early Majority into Early Adopters

A while ago we came up with the idea to investigate the intersection between change management and artificial intelligence (AI) in radiology. We wanted to assess independent predictors for being a so-called ‘early adopter’, inspired by Roger’s Innovation Diffusion theory. An early adopter, coming right after the innovator, is someone who wants to take a risk without getting an immediate

Initial chest radiographs and artificial intelligence (AI) predict clinical outcomes in COVID-19 patients: analysis of 697 Italian patients

The purpose of this retrospective study was to evaluate whether initial chest X-ray (CXR) severity assessed by an AI system may have prognostic utility in patients with COVID-19. The authors determined, through AI- and radiologist-assessed disease severity scores on CXRs obtained on emergency department (ED) presentation, that they were independent and comparable predictors of adverse outcomes in patients with COVID-19.

Practical applications of deep learning: classifying the most common categories of plain radiographs in a PACS using a neural network

The purpose of this study was to classify the most common types of plain radiography through the use of a neural network and, subsequently, to validate the network’s performance on internal and external data. The authors used data from a single institution when classifying the most common categories of radiographs. This study resulted in the authors determining that it is

Applications of artificial intelligence (AI) in diagnostic radiology: a technography study

Although a lot of developments are made in the area of artificial intelligence (AI) in radiology and the number of publications is ever-increasing, the adoption in clinical practice still seems to lag behind and is limited to a small number of tools. To analyze this situation, we conducted a so-called technographic study. In this study, we identified 269 AI applications

How can we combat multicenter variability in MR radiomics? Validation of a correction procedure

In this study, the authors extended the ComBat approach to provide a harmonization procedure that is applicable to any radiomic feature. They achieve this by combining image standardization with ComBat realignment, thus demonstrating that this could efficiently remove the scanner/protocol effect while preserving the individual variations in phantom, brain, and prostate MR scans. Key points Radiomic feature values obtained using

The promising possibility of using AI in mammography screening

In two recent publications in European Radiology, we have addressed two, of several, challenges with mammography screening. Firstly, the vast majority of screen exams are normal, which is resource-demanding, especially in the double-reading setting; and secondly, we miss cancer that can be particularly aggressive, later appearing as interval cancer. To understand if artificial intelligence (AI) can identify normal exams, we
