alt_dicominfo(img,B​itRange)

Faster and simplest alternative to dicominfo function (only demographic and basic image information)

I made this code aiming to avoid the MATLAB DICOMINFO function into my loops. This function may replace the original dicominfo if you only seek demographic and image basic information (described below) from the header. The MATLAB DICOMINFO is very slow due the amount of data indexed. Comparing to the original DICOMINFO in a large MRI DICOM file (4D file), this function may be 100 times faster.
I am not sure if the code will work for every type of DICOM files and I ask you to use this function with responsibility.
Add a dicom (*.dcm) image in variable img and add or not a bit range to search into your image. The code will try to give an oputput as described:
