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.

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.

Indirect traumatic optic neuropathy (ITON) is a devastating cause of permanent visual loss. Axonal degeneration, the characteristic pathological change of ITON, cannot be assessed by conventional imaging. Diffusion tensor imaging (DTI) has been widely used as a sensitive non-invasive imaging technique to obtain information on axonal integrity. ⋯ DT-MRI parameters could be useful biomarkers in detecting ON changes in ITON patients.

Computed tomography (CT) of the brain is used extensively in the urgent work-up of patients with a suspicion of intracranial pathology, but is often normal. Previously proposed selection criteria aim at limiting the ordering of urgent cranial CT in the non-trauma population, while maintaining high sensitivity for diagnoses demanding immediate attention. ⋯ Although 100% sensitivity was not achieved, our results may contribute to the evidence that in the absence of focal neurologic deficit, headache with vomiting or altered mental status in patients aged <60 years cranial tomography can be refrained from, in the general population as well as in the subgroup defined above. Further research might validate patient history as a parameter.
