Osteoporotic vertebral biconcave-shaped fractures are not commonly seen in clinical practice. Some articles have been published showing the outcome of vertebroplasty (PV) and balloon kyphoplasty (BKP), but few comparative studies have been performed. ⋯ Both PV and BKP achieved similar improvements in pain and functional outcomes for the treatment of osteoporotic vertebral biconcave-shaped fractures. BKP had a significant advantage over PV in terms of the restoration of the middle vertebral height and fewer cement leakages than PV.

The multiple prominent hypointense veins on susceptibility-weighted imaging (SWI) have been found in the ischemic territory of patients with acute ischemic stroke. Venous side is the unknown area in the hemodynamics of brain infarction. ⋯ The prominent hypointense veins on SWI were seen in the half of the acute infarction at 4 days. The prominent hypointense veins on SWI may have good agreement with the increased MTT ratio.

Diffusion tensor imaging (DTI) with fiber tracking (FT) has found clinical applications in the evaluation of the central nervous system and has been extensively used to image white matter tract. The feasibility of FT of the lumbar nerve roots in disc herniation is unclear. ⋯ 3 T magnetic resonance imaging (MRI) DTI and FT of the lumbosacral region nerve is possible. There are significant changes in FA and ADC values in the compressed L4, L5, and S1 nerves.

Deep neck infection is not difficult to diagnose clinically, but correct localization of the involved space for timely incision and drainage is not easy without assistance of imaging. ⋯ CT and MRI play a crucial role in both the diagnosis and correct puncture and incision for drainage of the deep neck space infection.
