ExamCard purpose

This ExamCard uses CIA (Combined Image Aquisition) Panoramic imaging for the lumbar spine and the SI joint with Flex L+ and Flex M+ coils. The Panoramic method was introduced in R6.1 and CIA features were introduced in R6.2. This ExamCard requires both Panoramic and CIA licenses.

 

This ExamCard is used to image the SI joint, primarily for suspected ankylosing spondylitis. Increased signal on STIR images and after i.v. gadolinium increased signal in post-contrast fat sat T1w images suggest an active spondylitis.

 

SENSE is used in the sagittal plane to shorten the acquisition times.

 

Examination time is about 22 minutes in addition to patient preparation and positioning times.

Patient positioning

CIA (Combined Image Aquisition) Panoramic imaging combines the two Flex coils M+ and L+ (using both coils at the same time is CIA Imaging).

 

  • The patient is firmly positioned sideways using the vacuum mattress, looking outside (Panoramic imaging). 
  • Two special Flex M+ and L+ coils are positioned in the same-plane way behind the back of the patient.
  • Position the patient on the vacuum cushion sideways.
  • If needed, place the pad between the knees for the patient comfort.
  • If needed, use thinner mattress under the patient.
  • Place the Flex M+ and Flex L+ coil on the same plane behind the patient´s back.
  • Support the coils with the coil holders, pads or sandbags and pump the air out of the vacuum cushion.
  • Use the "low" tabletop height setting.
