Figure 1. Micro CT and X-Ray imaging of cisterna magna injection.

Figure 1

A: micro CT images (HU range −200 to 1200) collected before (control) and immediately after injection of a 1∶1 mixture of blood and the contrast agent Imerone 400 (SAH). The contrast agent is visible in the subarachnoid space and in the entire ventricular system. B: X-ray of before blood-Imerone 400 injection (control). C: X-ray collected immediately after blood-Imerone 400 injection into the cisterna magna. Note the high concentration of contrast agent in the area corresponding to the basal cistern but also quick dispersion into more cranially located regions. D: two exemplary micro images of the SAH group with a high magnification.
