For three-dimensional reconstruction of the MR images, all source data were sent to Philips' clinical workflow solution (Extended Brilliance Workspace V 4.5; Philips Healthcare, Best, the Netherlands). There were 20 images for T2WI and T2*WI, and 40 for the SWI sequence. The single sequence data from each rat was individually processed. First, the MRI data were accessed through the volume mode of the workflow solution. The infarction area and dark signal regions were selected by free hand using the tissue segmentation function on each image. The color yellow was assigned to the high signal areas of the infarction, and the color red to the dark signal regions from the SPIO (Fig. 1 ). Each segmented image was automatically processed using the tissue management function, and three-dimensional images were displayed using the volume-rendering mode. Subsequently, quantitative volumes (mm3) of the infarction and the SPIO were obtained using the calculate-volume tool. Using the three-dimensionally reconstructed image, the relationship between the location of the infarction and the SPIO-labeled hBM-MSCs was observed. In particular, the location differences of the stem cells' homing between the ICA and IV group were qualitatively observed.

The volume of the spleen was calculated using unenhanced CT images of the upper abdomen, acquired on day one (between 24 and 48 hours after stroke) and day seven (between 144 hours and 168 hours after stroke). Spleen images were transferred to a dedicated workstation (AW workstation VolumeShare 7, General Electric Healthcare, Milwaukee USA or Extended Brilliance Workspace V4.5, Royal Philips NV, Amsterdam, The Netherlands) on which spleen volumes were segmented and calculated in volume rendering. The entire volume in cm³ was displayed after acceptance by the operator. Spleen volume reduction was defined as a > 10% decrease in spleen size between days one and seven after stroke onset.

A multidetector spiral CT (Brilliance iCT, Philips Medical Systems, Cleveland, Ohio) was used (65 patients), and CTA was performed with the following parameters: standard modality, gantry rotation 0.4s, pitch 0.915, KV 120, mAs 300, collimation 128*0.625, matrix 512*512, thickness 0.9mm, increment-0.45mm, and Dose Length Product(DLP) 802.3mGy*cm.
A contrast agent (Ultravist, 370mgI/mL was used via the CT high-pressure syringe, with a moderate injection rate(4~5 mL/s) and dose(1.0~1.5 mL/ kg). Arterial, venous, and urographic phases were acquired after a bolus tracking test.
Images were post-processed on an independent workstation (Extended Brilliance Workspace V4.5, Philips Medical Systems, Cleveland, Ohio) to obtain multiplanar reconstructions (MPRs), maximum intensity projections (MIPs), as well as surface and volume renderings (Figure-1 ).
The computed tomography angiography was reviewed carefully by two radiologistes individually who were blinded to this study. Disagreements were resolved by two radiologists in a final consensus reading.

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.
