This is a subreddit to discuss the algorithms, physics, hardware, and results of medical imaging. Feel free to ask for advice on algorithms, ask for help in understanding the physics, discuss recent developments, or anything else. Also, discussions of ways to proliferate medical imaging technologies to impoverished nations are very appropriate. Finally, discussions of how to teach medical imaging are welcome!
This subreddit is not a place to submit your images and ask for a diagnosis. We are here to improve medical imaging, not to provide medical advice.

How To Verify Accuracy of FreeSurfer Cortical Reconstructions
I have been working with Freesurfer running reconstructions on Mp2rage MRI data for an internship, and while I think I have been able to figure out how to correctly skullstrip the noisy Mp2Rage image, the professor I am doing the internship with has said that the aseg and aparc results of the reconstruction are not totally accurate. I'm not sure why, although I suspect it's because the skullstrip still has some noise around the edges. I'm going to try brainvoyager or premade matlab scripts to denoise the mp2rage image rather than doing it manually by multiplying the mask generated for the skullstrip of the inversion pulse with the original image.
However, even if I figure out this issue I will still need a way to check my results. I am able to tell that the major structures of the brain are in the right place, but the professor told me this is not enough to verify that the reconstruction is an accurate representation of the original MRI data (which makes sense). I don't know how he's able to tell that the reconstruction is inaccurate by looking at the segmentation, but he wants me to actually run some type of analysis to figure out how to check the data rather than asking him.
He is being intentionally vague because he wants me to figure out how to do this without his help, but I am pretty stuck. He mentioned something about statistical analysis, but it wasn't clear what he meant. I am looking for any tips to mathematically verify that the reconstructions are accurate, and also possibly ways to fix inaccuracies that aren't too extreme.

Dicom viewer for deep learning models clinical validation
hi , we as a team developing AI health care product assisting the radiologist in the workflow. For validatibg our deep models upto now we used manual segregation and hard coded segmentation of anaomaly on jpeg images for the visualization. Now we want move to dicom where the segmentation contours and blues will be dropped onto dicom tags . is there any dicom viewer which can read these dicom tags and display the annotation results with a toggle button . We're interested in the sharing the feedback over the dicom platform which will be embedded into the dicom tags.
please suggest any dicom viewer that are relevant to our requirements.

Parahydrogen MRI
Does anyone know how long it is likely to be before this technology can be used to scan patients? Also, is it likely to be an improvement on current MRI (i.e. higher resolution), or just cheaper?
