If you use the option to append the raw output, you can extract the mime type from there.  I'm not sure what's going on in the background here, but it seems far less useful than the command line identify tool.

The array returned by Imagick::identifyImage():

Array
(
    [imageName] => /some/path/image.jpg
    [format] => JPEG (Joint Photographic Experts Group JFIF format)
    [geometry] => Array
        (
            [width] => 90
            [height] => 90
        )

    [type] => TrueColor
    [colorSpace] => RGB
    [resolution] => Array
        (
            [x] => 300
            [y] => 300
        )

    [units] => PixelsPerInch
    [fileSize] => 1.88672kb
    [compression] => JPEG
    [signature] => 9a6dc8f604f97d0d691c0286176ddf992e188f0bebba98494b2146ee2d7118da
)

Looks like the only way to get the mimetype is getimagesize()...
