The minimal spectral analysis methods described by MRS community consensus are not available in manufacturers’ MRS software. MRS data is still transferred off the scanner for advanced analysis leading to more variability in MRS results and impediments for adoption within a clinical DICOM workflow. We describe the Vespa Inline Engine (VIE), a flexible add-in module for the open-source Vespa spectral analysis package. VIE provides equivalent, inline MRS processing on GE, Siemens and Philips platforms. Raw MRS data sent to the VIE analysis returns results to the DICOM workflow as graphical and tabular DICOM images.
