imageDatastore function error reading image files

I have dataset with *.mhd data file format and want to read the dataset with imageDatastore the I face the next error

Error using imageDatastore (line 116)

Input folders or files contain non-standard file extensions.

Use FileExtensions Name-Value pair to include the non-standard file extensions.

Are there any help?

Add the option 'FileExtensions', '.mhd'

You will also need to add a ReadFcn property and supply a function handle to a function that reads the mhd file. imageDatastore normally uses imread() to read files, and imread() does not support .mhd files.
