Real-time MR imaging might exert a profound influence on neuroscience in the future by enabling the direct visualization of neuronal interactions. At this time, however, all practical embodiments of MRI require at least some degree of gradient encoding, and this in turn sets a lower limit of about 100 ms for volume acquisition. ⋯ This permits a rate of signal acquisition that is increased hundreds of times compared with existing techniques, with full 3-D imaging in as little as one millisecond. The proposed detector now resembles a holographic recording.

Review Case Reports
Thrombosed dural sinus malformation in a fetus: a case report.
A thrombosed dural sinus malformation (DSM) is a rare condition, the clinical features of which have not yet been completely characterized. Here, we describe the clinical course of a patient with a thrombosed DSM and discuss the outcomes in live birth cases from a review of the literature. ⋯ Although normal cranial circumference is reportedly an essential factor for a favorable prognosis, the patient in this report with a cranial circumference at + 2.0 SD (35.6 cm) had a favorable prognosis. Further studies focused on improving clinical diagnostic accuracy in this rare entity will facilitate appropriate counseling.
