Computer aided detection (CAD) is a technology designed to decrease observational oversights--and thus the false negative rates--of physicians interpreting medical images. Prospective clinical studies have demonstrated an increase in breast cancer detection with CAD assistance. This overview briefly describes the metrics that have been used to define CAD system performance.

Background: Identifying and eliminating health disparities is a public health priority. The goal of this analysis is to determine whether cardiac testing or outcome disparities exist by race or sex in patients with detectable to mildly elevated serum troponin.
Methods: We conducted a secondary analysis of the CMR-IMPACT trial that randomized patients with symptoms suggestive of acute coronary syndrome and a detectable or mildly elevated troponin measure from 4 US hospitals to an early invasive angiography or cardiac MRI strategy.

BACKGROUND Coronary artery ectasia (CAE) is frequently present with coronary artery disease (CAD). However, it is not clear why some patients with CAD progress to CAE while others do not. The pathogenesis of CAE is still poorly elucidated.

Background: Histotripsy is a non-invasive, non-ionizing, non-thermal focused ultrasound technique. High amplitude short acoustic pulses converge to create high negative pressures that cavitate endogenous gas into a bubble cloud leading to mechanical tissue destruction. In the United States, histotripsy is approved to treat liver tumors under diagnostic ultrasound guidance but in initial clinical cases, some areas of the liver have not been treated due to bone or gas obstructing the acoustic window for targeting.

Background: This study aims to identify optimal acceleration factors (AFs) for compressed sensing (CS) technology to enhance its clinical application for suspected coronary artery disease (CAD) in whole-heart non-contrast coronary magnetic resonance angiography (CMRA).
Methods: Two hundred and seventeen individuals with suspected CAD underwent whole-heart non-contrast CMRA on a 1.5-T CMR scanner with CS AFs of 2, 4, and 6 (CS2, CS4, and CS6).

Breast cancer is one of the most aggressive types of cancer, and its early diagnosis is crucial for reducing mortality rates and ensuring timely treatment. Computer-aided diagnosis systems provide automated mammography image processing, interpretation, and grading. However, since the currently existing methods suffer from such issues as overfitting, lack of adaptability, and dependence on massive annotated datasets, the present work introduces a hybrid approach to enhance breast cancer classification accuracy.
