From community-acquired pneumonia to COVID-19: a deep learning–based method for quantitative analysis of COVID-19 on thick-section CT scans

In this retrospective study, the authors aimed to develop a fully automated artificial intelligence (AI) system to quantitatively assess the severity and progression of COVID-19 using thick-section chest CT images. Through their research and work, they were able to determine that a deep learning-based AI system built on thick-section CT imaging can accurately quantify COVID-19-associated abnormalities in the lung and

Artificial Intelligence to Help Radiologists in the Early Detection of Breast Cancer with Mammography and Breast Tomosynthesis

During the COVID-19 pandemic, routine breast cancer screening is largely being put on hold in many countries. Although it is not directly related, Sars-CoV-2 will have an effect on breast cancer screening and care. Having a closer look to Germany for instance, letters inviting women to screening were suspended until April, 30th.* The enormous decline in breast cancer screening is

Automated identification of chest radiographs with referable abnormality with deep learning: need for recalibration

The purpose of this study was to evaluate the calibration of a deep learning (DL) model in a diagnostic cohort, as well as to improve the model’s calibration through recalibration procedures. The authors found that the calibration of the DL algorithm can be augmented through simple recalibration procedures, and improved calibration may enhance the interpretability and credibility of the model

Automated detection of pulmonary embolism in CT pulmonary angiograms using an AI-powered algorithm

The detection of pulmonary embolism (PE) in CT pulmonary angiograms (CTPAs) is a great example of a major challenge radiologists face nowadays: The swift identification and communication of critical findings in times of sharply rising numbers of examinations performed. A potential auxiliary tool helping us to master the flood of information and separate signal (critical findings) from noise (unremarkable examinations)

Improved characterization of sub-centimeter enhancing breast masses on MRI with radiomics and machine learning in BRCA mutation carriers

This retrospective study aimed to investigate whether radiomics features extracted from MRI of BRCA-positive patients with sub-centimeter breast masses can be coupled with machine learning in order to differentiate benign lesions from malignant lesions using model-free parameter maps. The authors determined that radiomics analysis coupled with machine learning does improve the diagnostic accuracy of MRI in characterizing sub-centimeter breast masses

A fully automated software platform for structural mitral valve analysis

There has been great interest in the development and application of artificial intelligence (AI) in the field of medical imaging. AI has the potential to be useful in multiple arenas including the improvement of diagnostic accuracy as well as improving workflow and helping increase human efficiency in study interpretation. Cardiac imaging has been one focus of AI and has yielded

AI in Risk-Based Breast Screening

Artificial intelligence tools and technology are becoming more ingrained in the radiological discipline, but only recently in breast imaging, more specifically mammography and breast screening. Dr. Ritse Mann discussed with us the impact that AI is having on breast screening techniques and workflow, the current role it plays in hospitals and as an assistant to radiologists, and its future in

Emphysema quantification using low-dose computed tomography with deep learning-based kernel conversion comparison

This study used a sample of 131 participants who underwent low-dose computed tomography (LDCT) and standard-dose computed tomography (SDCT) to determine the effect of dose reduction and kernel selection on quantifying emphysema. The authors determined that the deep learning-based CT kernel conversation of sharp kernel in LDCT significantly reduced the variation in emphysema quantification. Key points Low-dose computed tomography with

Clinically significant prostate cancer detection and segmentation in low-risk patients using a convolutional neural network on multi-parametric MRI

The purpose of this study was to develop an automatic method for the identification and segmentation of clinically significant prostate cancer in low-risk patients and evaluate this performance in a routine clinical setting. The authors discovered that the proposed deep learning computer-aided method showed promising results in the previously-mentioned identification and segmentation of clinically significant prostate cancer in patients on

Radiomics nomogram of contrast-enhanced spectral mammography for prediction of axillary lymph node metastasis in breast cancer: a multicenter study

The aim of this retrospective study was to establish and validate a radiomics nomogram that was based on contrast-enhanced spectral mammography (CESM) for the prediction of axillary lymph node (ALN) metastasis in breast cancer. The authors found that the CESM-based radiomics nomogram showed good application prospects in the preoperative prediction of ALN metastasis in breast cancer. Key points The CESM-based
