According to the ACR-ASNR guidelines for myelography and cisternography
, "historical or laboratory evidence of bleeding disorder or coagulopathy" is cited as a relative contraindication (9).
Evaluation of MR cisternography
of the cerebellopontine angle using a balanced fast-field-echo sequence: preliminary findings.
All second-line treatments require leak localization with spinal imaging, such as MRI, CT, myelogram, and nuclear medicine cisternography
Various methods are used for diagnosis such as brain MRI, MR or CT myelography, and radionuclide cisternography
. MRI findings are subdural fluid collections, pachymeningeal enhancement, sagging of the brain structures, and engorgement of venous structures (1).
The diagnostic criteria of traumatic CSF leakage is defined as follows: (1) early vesicular radioisotope cisternography
(RIC) accumulation (EVA); (2) promoted radioisotope (RI) clearance from the spinal cavity; (3) presence of abnormal paraspinal RI accumulation (PSA) .

Contrast-enhanced CT (CECT) scan with cisternography
revealed a large lobulated mass of size 81 x 53 x 82 mm in the left zygomatic and masseteric region with intracranial extension (Figure 1(a)).
Surgical repair and detection of cerebrospinal fluid rhinorrhea using magnetic resonance cisternography
and skull base coronal thin-section computed tomography scan.
and radionuclide cisternography
can be used if a defect is not detected on CT.
There are data to support the use of either high-resolution CT scan, MRI, or CT/MRI cisternography
for diagnosis of the basilar skull defects in CSF rhinorrhea .
including FIESTA is useful in evaluations of the cystic wall because of the higher contrast-to-noise ratio and brain tissue/CSF contrast  but lacks contrast between soft tissues and even between soft tissues and bone .
