I am doing some project on medical image processing and I need some uncompressed medical images especially magnetic resonance angiography, vessel and so on. I have searched a lot but most of the available images are in JPEG format which is not a suitable format due to its lossy compression. Do you know any free dataset which have uncompressed medical images especially those mentioned?
The problem you are most likely having is that you need to search for files in the correct format. DICOM is what you need to look for. A few hits:
You will also need a DICOM viewer.
Image J is free (non-commercial, no restrictions on use) and can be used under Windows, Mac, and Linux - it does require Java.
There are other viewers available, free as well as commercial. Just search for DICOM viewers.
In order to understand this question better, please see the question What are characteristics of different MR images?.

There may be some medical dataset used for salient object segmentation here.
Quora has a label on Medical Information and Data but it is relatively hard to find MR images by it.
You have another famous and important source of information, the so well known DICOM Library. Intending for anonymization, the DICOM Library is sharing and viewing of DICOM Standard online.
For instance, if you want a parser to it you have the DICOM Parser in Go repository. It is a DICOM Parser developed in the Go Programming Language.
