Peripheral nerve diffusion tensor imaging: Overview, pitfalls, and future directions

“…Others may branch into multiple divisions or diverge around tumors, fracture callous, or postoperative fluid collections. In the case of a peripheral nerve sheath tumor, when the angle tolerance exceeds the threshold in fiber tracking, fiber tracking can be falsely terminated …”

“…Nerve fiber integrity has been assessed longitudinally with DTT immediately following injury (Fig. c–f) and during the recovery phase . One study reports the ability of DTT to demonstrate nerve regeneration at the injured site prior to EDX recovery .…”

“…Previous DTI studies have not consistently agreed on the optimum number of gradient directions for the periphery. The minimum of six directions has been used at 1.5T and as many as 25 gradient directions at 3.0T, both to evaluate the median nerve . Most 3.0T studies fall in the middle of this range .…”

“…2c-f ) and during the recovery phase. 20,26,49 One study reports the ability of DTT to demonstrate nerve regeneration at the injured site prior to EDX recovery. 3 Furthermore, DTT even changed the course of the surgical strategy in 25% of cases in soft tissue tumors.…”
