The intrathecal injection of 0.5 mL of gadopentetate dimeglumine diluted in 3-5 mL of CSF for MR cisternography has been reported to have high sensitivity and specificity for detection of active CSF fistula, exceeding the rate of fistula demonstration by CT, nuclear medicine, or noncontrasted MR cisternography. The lateral lamella of the cribriform plate appears to be involved in approximately 40% of the cases, whereas a defect in the region of the fontal sinus is detected 15% of the time. Another advantage is the ability to more accurately position underlay or overlay grafts. For more information, see the eMedicine topic Nephrogenic Systemic Fibrosis. 110(7):1166-72.

Water Dripping From Nose When Bending Over - A Cerebrospinal Fluid (CSF Preoperative Medical Treatment for Patients With Acromegaly: Yes or No? Liquorrhea - an overview | ScienceDirect Topics ), Leakage of CSF into the epidural space through a defect in the thecal sac has been found to be the underlying cause of almost all cases ofspontaneous intracranial hypotension (SIH). Several texts have suggested that CSF will separate from blood when the mixture is placed on filter paper or other media and will produce a clinically detectable sign, which has been referred to as a ring sign, double ring sign, or halo sign. Surgical repair of spontaneous cerebrospinal fluid (CSF) leaks: A systematic review. and transmitted securely. Blood-tinged fluid can be placed on filter paper to look for a double ring sign of CSF around blood, but this is not a reliable test. Another technique, the injection of intrathecal fluorescein, has been used not only to diagnose CSF rhinorrhea but to localize the site(s) where it occurs. Several surgical options for repair of CSF leaks arising from the anterior skull base exist. Typical imaging parameters include a repetition time of 10,000 ms, an effective echo time of 200 ms, 4 signals acquired, an echo train length of 16, a matrix of 512 X 192, no phase-wrap option, 3-mm sections interleaved contiguously (0-mm gap), and a 16-cm field of view. The image also shows a right-sided meningocele (large arrow) protruding through the cribriform plate, which was not suspected but was surgically repaired at the same time as the left cribriform cerebrospinal fluid leak site.
