It depends what your ‘medical image’ is. For most radiography (x-ray, ultrasound, MRI, CT, etc.) images, they are in DICOM format and you would read the images with .dcm file extensions (also termed suffixes) with the dicomread (link) function. If you want to save ‘slices’ of a computerized tomographic file as individual images, save them as uncompressed ‘.jpg’ images, since that is what they are in the DICOM file.

I would not save them as .jpg -- far too much chance that someone would not notice they are intentionally uncompressed and will proceed to helpfully compress them, which damages their value for research (makes the algorithms harder.) I would deliberately save them as some image type that does not use lossy compression such as PNG or TIFF.
DICOM does not mandate any one compression algorithm; it makes several available and provides mechanisms to use additional compression algorithms. Some of the compression algorithms tend to get used more often than others, of course.

This is too vague. Basically the answer is "you can use MATLAB." Here is how to learn it:
