“…Previous studies attempted to segment CSF in LVs using similar methodology with ours in healthy controls and MS patients . CSF in ventricles and subarachnoid space has been measured using computerized tomography in subarachnoid hemorrhage detection, T2‐weighted 3D spin echo sequences in normal pressure hydrocephalus and Alzheimer's disease, T2‐weighted sequence in traumatic brain injury, and 3D SPACE MR in hydrocephalus . Although comparing different methods of CSF segmentation is not in the scope of this study, we showed that DTI‐based wbCSF segmentation is feasible and can be used to monitor clinical symptomatology in patients with MS.…”

“…11,12 With this technique, thinner section images and 3D data (by using < 1-mm 3 voxels) can be acquired with acceptable acquisition time (approximately 5 minutes), minimizing the partial volume effect between small entities and surrounding tissue. 3,12 Our previous studies demonstrated that T2W 3D-SPACE with variant flip-angle mode images may show the flow dynamics of CSF in the ventricular system.…”

“…2,5 With the development of MRI technology, the whole cranium, including CSF-containing spaces (especially the ventricular system), and CSF circulation are better evaluated with 3D isotropic submillimetric data obtained by 3-T MR units. 3,11 By using a relatively new technique called 3D sampling perfection with application-optimized contrasts using different flip-angle evolutions (3D-SPACE) developed by Mugler et al, it has now become possible to scan the whole cranium with < 1-mm 3 voxels within an acceptable time period and without exceeding specific absorption rate limits in 3-T scanners.…”

E ndoscopic third ventriculostomy (ETV) is a minimally invasive, safe, and relatively new CSF diversion method; it is mostly used in aqueductal stenosis, but may also be indicated in the treatment of other causes of hydrocephalus.1 With this procedure the inferior wall of the third ventricle is fenestrated, and CSF in the ventricular system is diverted into the prepontine cisternthereby bypassing the obstruction-and CSF circulation is reestablished. 4,7 It is a more physiological treatment option compared with shunt procedures, and therefore it is being done with increasing frequency. 4,7,10 Clinical, laboratory, and conventional imaging findings may be useful to determine whether the ETV stoma is patent, although advanced radiological methods are mostly required. 2,6 Ventriculography is a gold-standard technique for determination of ETV patency. 4 On the other hand, abbreviatioNs ETV = endoscopic third ventriculostomy; PC = phase-contrast cine; T1W, T2W = T1-, T2-weighted; 3D-SPACE = 3D sampling perfection with application-optimized contrasts using different flip-angle evolutions. obJect The goal of this study was to determine the value of the 3D sampling perfection with application-optimized contrasts using different flip-angle evolutions (3D-SPACE) technique in the evaluation of endoscopic third ventriculostomy (ETV) patency. methods Twenty-six patients with ETV were examined using 3-T MRI units. Sagittal-plane 3D-SPACE with variant flip-angle mode, 3D T1-weighted (T1W), and 3D heavily T2-weighted (T2W) images were obtained with isotropic voxel sizes. Also, sagittal-axial plane phase-contrast cine (PC)-MR images were obtained. The following findings were evaluated: diameters of stoma and third ventricle, flow-void sign on 3D-SPACE and PC-MR images, integrity of the third ventricle on heavily T2W images, and quantitative PC-MRI parameters of the stoma. Obtained sequences were evaluated singly, in combination with one another, and all together. results The mean area, flow, and velocity values measured at the level of stoma in patients with patent stoma were significantly higher than those measured in patients with closed stoma (p < 0.05). There was significant correlation among PC-MRI, 3D-SPACE, and 3D heavily T2W techniques regarding assessment of ETV patency (p < 0.001). The 3D-SPACE technique provided the lowest rate of ambiguous results. coNclusioNs The 3D-SPACE technique seems to be the most efficient one for determination of ETV patency. The authors suggest the use of 3D-SPACE as a stand-alone first-line sequence in addition to routine brain MRI protocols in assessing patients with ETV, thereby decreasing scan time and reserving the use of a combination of additional sequences such as PC-MRI and 3D heavily T2W images in suspicious or complex cases.

“…3D sequences like SPACE (Sampling Perfection with Application optimized Contrasts using different flip angle Evolution) are well established in whole body MR imaging [2] and in selected neuroradiological indications [3]. The 3D approach allows isotropic high-resolution 3D images by using a slab selective, variable excitation pulse.…”
