“…[ 3 ] Compared with CTA and magnetic resonance angiography, fast spin echo (FSE) T2-weighted imaging (T2WI) is more feasible in depicting peripheral nerve. [ 4 , 5 ] However, FSE T2WI does not provide any quantitative parameters correlating with intrinsic characteristics of nerve. [ 6 ] Quantitative magnetic resonance (MR) sequences that are able to objectively assess nerve invasion are still urgently required.…”

To investigate the feasibility of readout-segmented diffusion-weighted (rsDW) magnetic resonance (MR) in assessing nerve invasion of soft tissue tumor. Forty-four patients with soft tissue mass in upper leg suspected of nerve invasion underwent rsDW MR. Nerve invasion by tumor was rated by 2 radiologists, respectively. Sensitivity and specificity of rsDW MR in identifying nerve invasion were calculated, with operation findings as reference of standard. Apparent diffusion coefficient and fraction of anisotropy of nerve were obtained using DW MR, and then were compared between invaded nerves and noninvasion cases. Inter-reader agreement in using rsDW MR to rate nerve invasion was excellent (kappa = 0.891 ± 0.043, P < 0.001). Sensitivity and specificity of rsDW MR in identifying nerve invasion were 89% and 88%, respectively. Apparent diffusion coefficient was significantly higher in invaded nerves versus normal nerves (1.45 ± 0.67 × 10 −3 mm 2 /s vs 1.39 ± 0.46 × 10 −3 mm 2 /s, P < 0.05). Fraction of anisotropy was significantly lower in invaded nerves versus normal nerves (0.22 ± 0.11 vs 0.37 ± 0.13, P < .05). Readout-segmented DW MR was feasible in assessing sciatic nerve invasion by soft tissue tumor in selected patients.

“…3 In recent years, fast spin echo (FSE) T2 weighted imaging (T2WI) was found useful in depicting peripheral nerve. 4,5 However, conventional T2 MR provides no quantitative parameter of nerve besides signal intensity. 6 Quantitative MR parameters are still urgently required to re ect the intrinsic character of nerve.…”

There are few publications regarding feasibility of readout-segmented diffusion tensor imaging (rsDTI) in assessing nerve invasion by soft tissue tumor. 64 patients with soft tissue mass in upper leg suspected of sciatic nerve invasion underwent rsDTI. Nerve invasion was confirmed in 28 cases by operation or electromyogram. The sciatic nerve was better depicted with diffusion weighted map versus b = 0 map of rsDTI. Inter-reader agreement in using rsDTI to rate nerve invasion was excellent. Sensitivity and specificity of rsDTI in identifying nerve invasion were 93% (26/28) and 92% (33/36) respectively. Apparent diffusion coefficient (ADC) was significantly higher in invaded nerves versus normal nerves (1.45 ± 0.67 × 10− 3mm2/s vs. 1.39 ± 0.46 × 10− 3mm2/s, P༜0.05). DTI derived FA was significantly lower in invaded nerves versus normal nerves (0.22 ± 0.11 vs. 0.37 ± 0.13, P༜0.05). Readout-segmented DTI was feasible in assessing sciatic nerve invasion by soft tissue tumor in selected patients.
