The intended use and indications for use for each of the types of Post-Processing Techniques described in this submission are described below.

ProPak Techniques

The ProPak Package for Picker MR systems or workstations provide supplemental information regarding contrast changes over time for those images extracted from MR temporal datasets. The indications for use for the MR system remain unchanged.

Diffusion Coefficient Mapping

The Picker Diffusion-Weighted MR Imaging Package has been designed to image the diffusive mobility of water or other proton-containing molecules. One important clinical application is to visualize the apparent loss of mobility of water molecules in brain tissue affected by acute stroke. Areas of decreased diffusion, as is observed in acute cerebral infarcts, appear as areas of higher image intensity. Post-processing using ADC mapping produces parametric images with further contrast manipulation.

Diffusion weighted MR pulse sequences are more accurate than conventional MRI pulse sequences in identifying the occurrence of acute stroke during the first 24 hours after onset of symptoms.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
