The following methods will also help you navigate the Data Set:
A volatile element is an element that can be changed or destroyed in the process of inserting or setting an image. A non-volatile element is an element that must be changed manually; it is not changed or destroyed by inserting or setting an image.
For example, a grayscale image has elements DicomTag.SmallestImagePixelValue, DicomTag.LargestImagePixelValue, etc. If the image is changed to a color image, these elements disappear and the following elements appear: DicomTag.RedPaletteColorLookupTableDescriptor, etc. These are volatile elements since they are changed or destroyed when an image is changed or set.
To retrieve a child element that must be changed manually, i.e., is not volatile, set includeVolatile to false. To retrieve a child element that may be either volatile or non-volatile, set includeVolatile to true.
