The authors applied peripheral pulse gating, which had been optimized to reduce artifacts in the cisterns attributable to cerebrospinal fluid (CSF) flow.<\/jats:p>\n<jats:p content-type=\"fine-print\"><jats:italic>Methods.<\/jats:italic> The detectability of each cranial nerve was determined in healthy volunteers. The first, second, and third nerves and the seventh\u2014eighth nerve complex were clearly visualized in all participants; the fifth nerve was clearly seen in 80% and the sixth cranial nerve in 50%. The fourth nerve and the ninth through 12th nerves were difficult to identify individually, except in some volunteers.<\/jats:p>\n<jats:p content-type=\"fine-print\">To reduce artifacts caused by fast CSF flow, we determined the delays as a function of the time elapsed between two consecutive peaks of pulse wave in a peripheral pulse gate (P\u2014P interval) at which there was reversal of flow direction to minimize the CSF flow\u2014related artifact. Using peripheral pulse gating and a time delay of 30% of the R\u2014R interval, the authors succeeded in minimizing the CSF flow\u2014related artifacts.<\/jats:p>\n<jats:p content-type=\"fine-print\">Magnetic resonance cisternography appears to be very useful for demonstrating intracisternal fine anatomy and enhancing the contours of the juxtacisternal lesion. A minute amount of CSF interposed between lesions and normal structures such as nerves, vessels, or bone structures can be detected by means of this sequence. In patients with facial spasm, axial images and oblique coronal images obtained in a plane parallel to the seventh\u2014eighth cranial nerve complex demonstrated vascular compression in all 13 patients. The MR cisternography finding of compression was confirmed in all nine patients who underwent microvascular decompression.<\/jats:p>\n<jats:p content-type=\"fine-print\"><jats:italic>Conclusions.<\/jats:italic> Magnetic resonance cisternography appears to show great promise for evaluation of patients with neurovascular compression or tumors in and around the basal cisterns; the procedure adds only a small amount of imaging time.<\/jats:p>","DOI":"10.3171\/jns.1998.88.4.0670","type":"journal-article","created":{"date-parts":[[2009,6,16]],"date-time":"2009-06-16T02:14:27Z","timestamp":1245118467000},"page":"670-678","source":"Crossref","is-referenced-by-count":33,"title":["Magnetic resonance cisternography for visualization of intracisternal fine structures"],"prefix":"10.3171","volume":"88","author":[{"given":"Yoshiaki","family":"Mamata","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Isao","family":"Muro","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mitsunori","family":"Matsumae","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Taizo","family":"Komiya","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroyuki","family":"Toyama","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ryuichi","family":"Tsugane","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Osamu","family":"Sato","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","doi-asserted-by":"crossref","first-page":"425","DOI":"10.1118\/1.595535","volume":"11","author":"Bottomley PA","year":"1984","journal-title":"Med Phys"},{"key":"b2","doi-asserted-by":"crossref","first-page":"443","DOI":"10.1148\/radiology.154.2.3966131","volume":"154","author":"Bradley WG","year":"1985","journal-title":"Radiology"},{"key":"b3","first-page":"1647","volume":"15","author":"El Gammal T","year":"1994","journal-title":"AJNR"},{"key":"b4","doi-asserted-by":"publisher","DOI":"10.1002\/mrm.1910060405"},{"key":"b5","doi-asserted-by":"crossref","first-page":"303","DOI":"10.1002\/mrm.1910030214","volume":"3","author":"Hopkins AL","year":"1986","journal-title":"Magn Reson Med"},{"key":"b6","unstructured":"Lang J:Skull Base and Related Structures: Atlas of Clinical Anatomy.Stuttgart: Schattauer, 1995, p 81"},{"key":"b7","doi-asserted-by":"crossref","unstructured":"Samii M, Draf W, Lang J:Surgery of the Skull Base.
