The University of Pennsylvania has reached an extended agreement with Siemens to disseminate arterial spin labeling (ASL) pulse sequences. Currently, we are providing both pulsed and continuous ASL sequences. The pulsed ASL sequences can be run at 1.5, 3.0 and 4.0T with array coil and parallel imaging. The continuous ASL sequence currently can be run at 3.0 and 4.0T with Transmit/Receive coil (and custom built detunable transmit coil with array receiver). We provide IDEA versions VA21, 23, 25 and VB11, 12, 13. The sequences were written by Jiongjiong Wang, Ph.D. and has been described in several publications. In order to receive the code, you must have a research agreement with Siemens and runs the IDEA platform for sequence programming and compiling. The proper installation and implementation of the sequences require understanding of the underlying concept of ASL as well as the adjustment of several parameters. As a research tool, no formal support is provided at present.
If you want to get a copy of the ASL sequence, please fill out this form. The procedure is that the technology transfer center at the University of Pennsylvania will send you a package of documents to sign (including the extended agreement with Siemens and a material transfer agreement). Once you sign and send them back, the technology transfer center at the University of Pennsylvania will sign and send them to Siemens. We will send you the code after these processes. The paperwork is to protect University of Pennsylvania’s intellectual property over ASL, IDEA of Siemens and any potential adverse events.
