The MPR Meta-Data Sheet

This modal sheet displays meta-data extracted from DICOM file meta-data tags. If using a series of image files exported from OsiriX in Raw.nnn file format you may need to manually override the 16-bit pixel representation to the Signed setting. PS uses the value stored in the hexadecimal slice thickness tag (0x0018,0x0050) and the decimal filename tag (.nnn) to calculate the z coordinate of Raw.nnn files. For some image series, you might also need to manually set the slice thickness to instead use the value found in the DICOM slice spacing tag in order to create properly scaled 3D reconstructions.
