Volume 44 of the Journal of Statistical Software was published in October 2011.  The special volume on “Magnetic Resonance Imaging in R” features articles and packages related to a variety of imaging modalities:

• functional MRI
• diffusion-weighted MRI
• dynamic contrast-enhanced MRI
• dynamic susceptibility-contrast MRI
• structural MRI

The papers describe the methodology, software implementation and provide comprehensive examples and data.  A complete list of the issues is:
