Veterinary Radiology & Ultrasound cannot accept Microsoft Word 2007 documents at this time. The newest version of Word, which saves documents with a .docx file extension, potentially causes problems with journal production because it handles equations edited within Word as images.
Word 2007 documents cannot be opened with a previous version of Word, but Word 2007 will support the ability to save the document in the older format (.doc). Please use Word's "Save As" option to save your document as an older (.doc) file type.
