We found that in Group I (PV), the mean imaging time was 106.34 ± 19.08 s, the mean needling time was 412.36 ± 28.19 s, and hence the mean performance time was 8.64 ± 0.54 min, whereas in Group II (PN), it was 132.83 ± 6.17 s, 739.09 ± 11.31 s, and 14.53 ± 0.20 min, respectively, which was statistically highly significant ( P < 0.0001) [ Table 2 and Graphs 1 – 3 ].
