Welcome to the Protocol Section:
Here is a good place to start if you are looking to get a new scan. Weather it is for personal, medical or legal reasons, a good scan provides a good objective piece of information. Then with a good scan, illustrations, animations, legal exhibits & interactive presentations turn out much better.
I have had the opportunity to collect a variety of DICOM readers over the years. I have also found that sometimes the older DICOM readers work better. For that reason I have a LINK to an old version of ClearCanvas and several versions of OsiriX. I hope you find them useful.
Sample CT Protocol:
“Click Here” to download PDF version of the CT Protocol. You can also see what is possible with a high resolution CT scan by looking below and clicking on the play button.
Sample MRI Protocols:
The Alzheimer’s Disease Neuroimaging Initiative (ADNI) has adapted a wonderful protocol to a variety of scanners. If you “Click Here” you will be directed to ADNI web site where you can download a protocol to suite your system. I am personally fond of the ADNI GO (3T) sequences. With this type of protocols followed, many types of 3D reconstruction and quantification are possible. You can see what I mean by looking below and clicking on the play button.
If you would like to run the program on your computer “Click Here” and you will be directed to a new site where you can download the software from. Be sure to install both programs.
Side by Side comparison of CT & MRI sequences:
These scans are of a normal individual whose images are all co-registered. All scans are in an Axial view meaning you are looking down on top of the brain. The animation starts at the base of the head and then goes up one slice at a time until it reaches the top of the head. The video has several different scan sequences. There is a CT or Computed Tomography scan. There is a is a T1 looking Ultrafast 3D Gradient Echo sequence that is some times called a SPGR or MPRAGE scan. There is also a FLAIR or Fluid Attenuated Inversion Recovery sequence. There is also a PD or Proton density sequence.
DTI MRI sequences:
These scans are of a normal individual. The first video is of a the DTI Tractography and the second is of the same data only showing the 2D colorized FA values. Green, in both videos, shows fibers running front to back. Blue shows fibers running inferior superior. Red shows fibers running left and right.
