DICOM parser in Go 
Usage
package main
import (
"fmt"
"github.com/gillesdemey/go-dicom"
"io/ioutil"
)
func main() {
bytes, err := ioutil.ReadFile("myfile.dcm")
parser, err := dicom.NewParser()
data, err := parser.Parse(bytes)
for _, elem := range data.Elements {
fmt.Printf("%+v\n", &elem)
}
}
Commandline Interface
dicom -file=myfile.dcm
Will print something like:

Acknowledgements
I'd like to thank my friend Seppe Stas for helping me get through the horrific DICOM image specification and some of the harder parts of the parser.
Some more inspiration and helpful resource that brought this library to life (in no particular order):
