Hi User, Use DVTkHighLevelInterface dll as reference and implement following code: public int readDicomFile(string filePath) try { } catch() { ............ } } Through Catch you can see the exception if it's not a DICOM file. Get back to us for any further query. Regards, Piyush

Hi Piyush,
any news/suggestions regarding the issue that "also .gif .exe and even .doc file are read as it was a dicom file"? In my implementation also DVTK dlls are correctly read! Thanks in advance.

Hi Sara,
besides checking for an exception thrown, also look at the following property: dcFile.FileMetaInformation.DicomPrefix. This should be the four bytes "DICM" in case of a DICOM file. Regards, Marco

Hi Marco,
thank you very much for your suggestion. I tried it, but I'm not sure to have correctly understood. In fact: I checked the value of dcFile.FileMetaInformation.DicomPrefix when reading both a DICOM file and a DLL file. In both cases it's a byte array containing the following four byte elements: '68', '73', '67', '77'. Where am I wrong? I thank you in advance for your kind help! Sara.

Hi Sara, But this won't help you right now. What you could also try of course is the following. According to part 10, a valid DICOM file should always start with the following:
A fixed 128 byte field available for Application Profile or implementation specified use. If not used by an Application Profile or a specific implementation all bytes shall be set to 00H.
File-set Readers or Updaters shall not rely on the content of this Preamble to determine that this File is or is not a DICOM File.
Four bytes containing the character string "DICM". This Prefix is intended to be used to recognize that this File is or not a DICOM File.
So if you Open a file using the normal Microsoft .Net classes and you inspect bytes 129-132 if they equal DICM, you can determine whether you're dealing with a DICOM file or not.
Please let me know if this solution works for you. Regards,
