“…The criteria for a CSF fistula on a 3D-CISS sequence were as follows [5][6][7]: (i) the presence of a defect between the bone-dura interface and (ii) hyperintense CSF or continuation of CSF towards paranasal sinuses. In addition to this, extracranial extension of brain tissue or meninges or soft-tissue intensity at the paranasal sinuses, representing a sinus tract, were also accepted as signs of a fistula.…”

“…High-resolution CT (HRCT) is helpful for detecting defects in the bony elements, but direct evaluation of the leak is not possible, which is the major limitation of the technique [4,5]. CT cisternography (CTC) can also show the leak localisation, but ionising radiation and the application of iodine-based contrast material are the major disadvantages of this technique [3].…”

“…In the literature, there are a limited number of articles concerning the value of unenhanced MR cisternography (three-dimensional constructive interference in steady state (3D-CISS)) and contrast-enhanced MR cisternography (CE-MRC) obtained with fat-suppressed (FS) T 1 weighted sequences for demonstrating CSF leak [3][4][5][6][7][8]. The aim of this prospective study was to explore the value of unenhanced and enhanced MRC in patients with rhinorrhoea.…”

ABSTRACT. The aim of this prospective study was to evaluate the value of unenhanced (three-dimensional constructive interference in steady state (3D-CISS)) and contrastenhanced MR cisternography (CE-MRC) in detecting the localisation of cerebrospinal fluid (CSF) leak in patients with rhinorrhoea. 17 patients with active or suspected CSF rhinorrhoea were included in the study. 3D-CISS sequences in coronal and sagittal planes and fat-suppressed T 1 -weighted spin-echo sequences in three planes before and after intrathecal contrast media adminstration were obtained. Images were obtained of the cribriform plate and sphenoid sinus. In addition, high-resolution CT (HRCT) was performed in order to evaluate the bony elements. The leak was present in 9/17 patients with 3D-CISS and 10/17 patients with CE-MRC. The leak from the cribriform plate to the nasal cavity in six patients and from the sphenoid sinus in four patients was nicely shown by CE-MRC. Eight of those patients were surgically treated, but spontaneous regression of the symptoms in two precluded any intervention. The leak localisations shown with CE-MRC were fully compatible with surgical results. The sensitivities of HRCT, 3D-CISS and CE-MRC for showing CSF leakage were 88%, 76% and 100%, respectively. In conclusion, 3D-CISS is a non-invasive and reliable technique, and should be the first-choice method to localise CSF leak. CE-MRC is helpful in conditions when there is no leak or in complicated cases with a positive b2-transferrin measurement.

“…This sequence also has a high signal intensity -tonoise ratio, inherent flow compensation, and is suitable for direct 3D imaging. 9,10 Although FIESTA is predominantly used for T2WI, it also enables T1 contrast and portrays contrast enhancement with increased concentration of gadolinium-based contrast reagents. 11 Therefore, previous studies have reported that contrast-enhanced (CE) FIESTA can enable visualization of the boundary between brain tumors and surrounding structures, and CE-FIESTA is effective for preoperative evaluation of skull base tumors.…”

Three-dimensional fast asymmetric spin echo (3D FASE) cisternography provides high spatial resolution and excellent contrast as a water image acquisition technique. It is also useful for the evaluation of various anatomical regions. This study investigated the usefulness and limitations of virtual endoscopic images obtained by 3D FASE MR cisternography in the preoperative evaluation of patients with neurovascular compression. The study included 12 patients with neurovascular compression: 10 with hemifacial spasm and two with trigeminal neuralgia. The diagnosis was surgically conˆrmed in all patients. The virtual endoscopic images obtained were judged to be of acceptable quality for interpretation in all cases. The areas of compression identiˆed in preoperative diagnosis with virtual endoscopic images showed good agreement with those observed from surgery, except in one case in which the common trunk of the anterior inferior cerebellar artery and posterior inferior cerebellar artery (AICA-PICA) bifurcated near the root exit zone of the facial nerve. The veins are displayed in some cases but not in others. The main advantage of generating virtual endoscopic images is that such images can be used for surgical simulation, allowing the neurosurgeon to perform surgical procedures with greater conˆdence.

3D steady-state MR cisternography in CSF rhinorrhoea

Abstract: In clinically suspected CSF rhinorrhoea, MRC is highly accurate in localising the site and extent of CSF fistula and may be used as the first investigation due to its efficacy and non-invasive nature.
