Results
The CNRs before the administration of SPIO were 3.05 ± 1.12 in the main portal vein, 2.27 ± 1.40 in the right portal vein, 2.25 ± 1.46 in the left portal vein, 2.16 ± 1.24 in the ascending peripheral branch (P8 or P7), and 1.79 ± 1.19 in the descending peripheral branch (P5 or P6). After the administration of SPIO, these values significantly increased to 5.31 ± 1.57, 4.18 ± 1.15, 4.77 ± 1.81, 3.86 ± 1.51, 3.74 ± 1.53, respectively (Table 3). The qualitative scores before the administration of SPIO were as follows: main portal vein, 3.93 ± 0.91; right portal vein, 3.34 ± 1.17; left portal vein, 2.82 ± 1.02; ascending peripheral branch (P8 or P7), 2.51 ± 1.17; and descending peripheral branch (P5 or P6), 1.95 ± 0.91. After the administration of SPIO, these values increased to 4.01 ± 0.66, 3.90 ± 0.78, 3.68 ± 0.98, 3.24 ± 0.95, and 2.86 ± 1.00; the increase was significant for all except the main portal vein (Table 4). Compared to the liver cirrhosis (LC) group, the non-liver cirrhosis (non-LC) group had a higher qualitative imaging score (Tables 5 and 6). These results indicated that spin labeling portography with SPIO was more effective than that without SPIO in depicting the portal vein.
Representative cases are shown in Figs. 2 and 3.
