One Sentence Abstract

"This paper reviews over 100 deep learning-based cardiac image segmentation studies across MRI, CT, and US modalities, discusses challenges and limitations, and proposes future research directions to improve interpretability, model generalizability, and address scarcity of labels."

Simplified Abstract

In this study, researchers explored how a popular tool, called deep learning, is used to help identify the heart's different parts in images like MRI scans, CT scans, and ultrasound. They looked at over 100 research papers using this technique and found that it's quite common and useful. They also listed some resources where others can access the images and tools needed to replicate their work.

Deep learning has some challenges, however. Sometimes, there aren't enough examples to learn from, the models don't work well in different situations, and it's hard to understand how the models arrive at their answers. The researchers suggest some ideas for future research to fix these issues.

In simple terms, this study is about using a specific technology to help identify different parts of the heart in images. The researchers analyzed many studies using this technology, listed helpful resources for others to follow suit, and identified some challenges with this technique. They also suggest ways to improve the technology in future studies.
