Trotz der unbestreitbaren Vorteile der MRT bleibt die CT-Myelografie eine wichtige
diagnostische Methode zur Darstellung der Wirbelsäule, etwa bei Lokalisation einer
Erkrankung im intraduralen extramedullären Raum oder wenn aus patientenbezogenen Gründen
die MRT nicht eingesetzt werden kann. Deshalb gehen die Autoren auf einige Indikationen
der CT-Myelografie ein und zeigen ihren Nutzen bei verschiedenen Wirbelsäulenerkrankungen.
Abstract
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 MRT, 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.
