Assessing cervical spine stability in obtunded blunt trauma patients: review of medical literature.
To review the current medical literature on dynamic fluoroscopic and magnetic resonance (MR) imaging assessment of cervical spine stability in obtunded patients who sustained blunt trauma. ⋯ Review of the current medical literature provided no clear evidence of the superiority of either MR imaging or dynamic fluoroscopy in the diagnosis of unstable ligamentous injury, although other relative advantages of MR imaging indicate that it is preferred for assessing cervical spine stability in obtunded blunt trauma patients.

To compare cancer yield for screening examinations with recommendation for short-interval follow-up after diagnostic imaging work-up versus after screening mammography only. ⋯ Many first screening examinations include recommendation for short-interval follow-up based on screening mammography alone. Cancer yield for these examinations is low and is lower than that with diagnostic work-up prior to short-interval follow-up recommendation. Absence of diagnostic work-up prior to short-interval follow-up recommendation may result in periodic surveillance of a high proportion of benign lesions.

To prospectively investigate if T2*-weighted dynamic susceptibility-weighted first-pass perfusion magnetic resonance (MR) imaging is feasible at 3.0 T and which dose of contrast agent is suitable for high-field-strength imaging. ⋯ With echo-shifted multishot echo-planar imaging, dynamic susceptibility-weighted perfusion MR imaging at high field strength is feasible without relevant image distortions. Compared with contrast agent dose for 1.5 T imaging, the dose for 3.0 T can be reduced to 0.10 mmol.
