A Novel Patient-Positioning Device for Dynamic CT Myelography

Area of Science:

• Medical Imaging
• Neurosurgery
• Radiology

Background:

• Dynamic CT myelography requires specific patient positioning to optimize contrast distribution within the thecal sac.
• Current methods for achieving spinal angulation can be challenging, impacting procedure efficiency and safety.

Purpose of the Study:

• To introduce and describe a novel patient-positioning device specifically designed for dynamic CT myelography.
• To evaluate the device's capability in controlling spinal angle and contrast flow.

Main Methods:

• Development of a novel patient-positioning device using a low-density reinforced polymer frame.
• Incorporation of a hand-operated mechanism for precise height adjustment and spinal angulation.
• Utilizing the device during dynamic CT myelography procedures.

Main Results:

• The device allows for precise adjustment of the spinal angle, facilitating controlled distribution of contrast agent.
• Demonstrated ability to manage the contrast bolus effectively along the dependent thecal sac.
• Reported increases in the safety, reproducibility, and sensitivity of dynamic CT myelography.

Conclusions:

• The novel patient-positioning device offers significant advantages for dynamic CT myelography.
• Precise control over spinal angulation and contrast flow enhances procedural outcomes.
• This innovation has the potential to improve the clinical utility of dynamic CT myelography.
