 [MIRT (Michigan Image Reconstruction Toolbox) in Julia](https://github.com/JeffFessler/MIRT.jl)
 
 This code is isolated from the main MIRT.jl toolbox,
-because testing these functions
+because complete tests of these functions
 requires large files
 that are not part of the repo.
-By such isolation,
-the code coverage reported
-over at
-[MIRT.jl](https://github.com/JeffFessler/MIRT.jl)
-is representative of the algorithms there,
-separate from I/O issues.
 
 The primary functions exported are for reading GE MRI kspace data:
 * `loadpfile`
 * `read_rdb_hdr`
 
+Utility functions for reading and writing fixed-length structured headers,
+which are common in legacy medical imaging formats,
+are in `src/ge-mri/header.jl`,
+such as `header_read` and `header_write`.
