Article Synopsis
- - This study investigates the effectiveness of an artificial intelligence (AI) algorithm in detecting incidental pulmonary embolisms (iPEs) in chest CT scans, comparing results before and after the AI implementation.
- - It analyzed data from 5,298 CT scans, revealing that prior to AI use, radiologists missed around 50% of iPE cases, with the AI achieving high sensitivity (95%) and specificity (99%) in identifying suspicious iPEs.
- - The study also aimed to assess the anatomical distribution of missed iPE cases and evaluate mortality rates in patients within 90 days following the different detection methods.
In this work, several machine learning (ML) algorithms, both classical ML and modern deep learning, were investigated for their ability to improve the performance of a pipeline for the segmentation and classification of prostate lesions using MRI data. The algorithms were used to perform a binary classification of benign and malignant tissue visible in MRI sequences. The model choices include support vector machines (SVMs), random decision forests (RDFs), and multi-layer perceptrons (MLPs), along with radiomic features that are reduced by applying PCA or mRMR feature selection.

The aim of this study was to investigate whether a U-Net-based deep convolutional neural network (dCNN) may be used to detect surgical clips in follow-up mammograms after BCS.
Methods: 884 mammograms and 517 tomosynthetic images depicting surgical clips and calcifications were manually segmented and classified.
Article Synopsis
- Traumatic abdominal wall hernia (TAWH) is a special kind of hernia caused by big hits or injuries to the stomach area, and it can block the intestines.
- The report talks about a patient who had a delayed problem in their intestines because of TAWH after breaking their hip bone.
- The patient got better after doctors used a special procedure to fix the hernia and then repaired the broken bone, showing how important it is for different doctors to work together quickly in tough cases like this.
Objective: To characterize the use and impact of radiation dose reduction techniques in actual practice for routine abdomen CT.
Methods: We retrospectively analyzed consecutive routine abdomen CT scans in adults from a large dose registry, contributed by 95 hospitals and imaging facilities. Grouping exams into deciles by, first, patient size, and second, size-adjusted dose length product (DLP), we summarized dose and technical parameters and estimated which parameters contributed most to between-protocols dose variation.
