A total of 20 rat skulls with brain intact were sent to the Duke University Center for In Vivo Microscopy for MRI in a 7.0 T Magnex magnet interfaced to an Agilent Direct Drive Console. Specimens where placed in plastic tubes and surrounded with Fomblin, a fluorocarbon used to limit artifacts from susceptibility mismatch between the surface of the brain and air. Data were acquired using a single turn sheet copper solenoid radio frequency coil. Images were acquired using a multi-gradient echo sequence with standard Cartesian encoding. The field of view was 40 mm × 20 mm × 16 mm with an acquisition matrix of 800 × 400 × 320 yielding Nyquist limited isotropic spatial resolution of 50 microns. The acquisition parameters were TR=50 ms, TE1=4.5 ms, and delta TE=9 ms. Four echoes were acquired at TE=4.5, 13.5, 22.5, and 31.5 ms. All four echoes were averaged to yield a single T2* weighted image for analysis. The flip angle was 60 degrees.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
