Safety and Technical Performance of Bilateral Decubitus CT Myelography Using Standard versus Increased Intrathecal Iodinated Contrast Volume.

ABSTRACT:

Background and purpose

Lateral decubitus CT myelography (LDCTM) is one of the main studies for the detection of CSF-venous fistulas, but detection of CSF-venous fistulas is dependent on intrathecal contrast attenuation. The purpose of this investigation was to assess the tolerability and technical performance of increased intrathecal doses of myelographic contrast compared with standard doses.

Materials and methods

This is a retrospective series of 24 patients who underwent LDCTM following administration of either 10 or 20 mL of intrathecal iodinated contrast media (300 or 320 mg/mL of iodine content). Patients were scanned in the initial lateral decubitus position and then turned to the contralateral side and re-scanned in the same session. The safety and tolerability of th
