Review
CT myelography is an important imaging modality that combines the advantages of myelography and the high resolution of CT. It provides a detailed delineation of pathologic spine conditions, especially those involving the thecal sac and its contents. However, the role of CT myelography has dramatically and appropriately decreased with the advent of MRI, which provides a noninvasive method to demonstrate pathologic spine conditions with high signal intensity in soft tissues. At the present time, CT myelography is often performed in patients who require evaluation of the thecal sac but have a contraindication to undergoing MRI. However, there remain many situations in which CT myelography is indicated and plays a critical role in patient treatment. The authors review common and uncommon indications for CT myelography and demonstrate various pathologic conditions in which CT myelography plays a vital role in patient treatment in this modern era of MRI.RSNA, 2020.

Review
In this article, we commemorate the centenary of myelography, a neuroradiological procedure that, despite certain disadvantages, significantly contributed to the diagnosis and localization of spinal cord lesions during the 20th century. From the start, the use of myelography was characterized by different views regarding the potential dangers associated with the prolonged exposure of a "foreign body" to the central nervous system. Such differences in attitude resulted in divergent myelography practices; its precise indications, technical performance, and adopted contrast material remaining subject to variability until the procedure were eventually replaced by MRI at the close of the 20th century.

Review
Despite recent trends toward evaluation of back and neck pain with magnetic resonance imaging, myelography and postmyelography computed tomography continue to play an important role in the workup of many patients with spinal pathology. We present techniques for the safe and efficient performance of myelography, lumbar, and cervical puncture, which remain important skills to be mastered by radiology residents and fellows.

Review
To summarize the points discussed in this article, Small animal myelography can be performed competently and safely without specialized equipment. The newer myelographic contrast media (iohexol, iopamidol) have less neurotoxic potential than those media previously used. Myelography is necessary for the diagnosis of many neurologic disorders in small animals. Metrizamide is no longer recommended for myelography in dogs and cats. Iohexol (Isovue) in concentration of 180 mg I/mL to 300 mg I/mL is recommended for small animal myelography. Some patients with serious spinal cord disease can exhibit normal myelograms. Recognizing abnormal myelographic patterns is the hallmark of myelographic interpretation. Anticonvulsive drugs (diazepam, pentobarbital, and phenobarbital) should be available for therapy of postmyelographic seizures. Epidurography is an effective diagnostic technique in the evaluation of canine lumbosacral compressive disease. Abnormalities identified with epidurography correlate well with surgically confirmed lesions.

Review
Myelographic contrast media of various types have been used over the past 100 years. Many of the early contrast agents had significant toxicities. Gas myelography was tried, but the contrast between gas and soft tissue is poor. Pantopaque, an oil-based iodinated medium was successfully used for decades, but was not compatible with computed tomography (CT) scanning because it was viscous, insoluble, and caused streak artifact. The development of water-soluble agents allowed even distribution in the subarachnoid space and excellent depiction of spinal anatomy on post-myelographic CT scanning. Although invasive, myelography will remain a useful tool for the foreseeable future.

Review
Digital subtraction myelography is a valuable diagnostic technique to detect the exact location of CSF leaks in the spine to facilitate appropriate diagnosis and treatment of spontaneous spinal CSF leaks. Digital subtraction myelography is an excellent diagnostic tool for assessment of various types of CSF leaks, and lateral decubitus digital subtraction myelography is increasingly being used to diagnose CSF-venous fistulas. Lateral decubitus digital subtraction myelography differs from typical CT and fluoroscopy-guided myelograms in many ways, including equipment, supplies, and injection and image-acquisition techniques. Operators should be familiar with techniques, common pitfalls, and artifacts to improve diagnostic yield and prevent nondiagnostic examinations.

Review
BACKGROUND AND PURPOSE
CSF-venous fistula can be diagnosed with multiple myelographic techniques; however, no prior work has characterized the time to contrast opacification and the duration of visualization. The purpose of our study was to evaluate the temporal characteristics of CSF-venous fistula on digital subtraction myelography.
MATERIALS AND METHODS
We reviewed the digital subtraction myelography images of 26 patients with CSF-venous fistulas. We evaluated how long the CSF-venous fistula took to opacify after contrast reached the spinal level of interest and how long it remained opacified. Patient demographics, CSF-venous fistula treatment, brain MR imaging findings, CSF-venous fistula spinal level, and CSF-venous fistula laterality were recorded.
RESULTS
Eight of the 26 CSF-venous fistulas were seen on both the upper- and lower-FOV digital subtraction myelography, for a total of 34 CSF-venous fistula views evaluated on digital subtraction myelography. The mean time to appearance was 9.1 seconds (range, 0-30 seconds). Twenty-two (84.6%) of the CSF-venous fistulas were on the right. The highest fistula level was C7, while the lowest was T13 (13 rib-bearing vertebral bodies). The most common CSF-venous fistula levels were T6 (4 patients) followed by T8, T10, and T11 (3 patients each). The mean age was 58.3 years (range, 31.7-87.6 years). Sixteen patients were women (61.5%).
CONCLUSIONS
This is the first study to report the temporal characteristics of CSF-venous fistulas using digital subtraction myelography. We found that on average, the CSF-venous fistula appeared 9.1 seconds (range, 0-30 seconds) after intrathecal contrast reached the spinal level.

Review
The Current Procedural Terminology of the American Medical Association has recently introduced coding changes for myelography with the introduction of new bundled codes. The aim of this review was to help neuroradiologists understand these code changes and their unintended consequences and to discuss various scenarios in which permutations of various codes could occur in clinical practice.
