When a study is compressed using lossy compression, no clinically significant data is lost; however, the original information cannot be completely reconstituted.
The only disadvantage is that it groups very similar colored pixels into a single color, which helps make such a small file size but causes what is known as lossy compression. It loses the original color sequence of pixels, but in most cases this is not noticeable.
