ExamCard description

This Release 5.1.7 ExamCard was created on Multiva 1.5T by the Bay-Tuna Radiology Center at the Beyhekim Devlet (MOH) Hospital in Konya, optimized for resolution and scan duration to image the peripheral arteries with the built-in quadrature body coil (QBC).

 

Three 3D imaging stacks at different anatomical levels (stations) are acquired before and after contrast administration.

 

A 2D BolusTrak scan is inserted between the pre- and post-contrast scans to enable the visual determination of contrast arrival in the anatomy of interest. 

 

SmartLine ImageAlgebra, PicturePlus and VolumeView steps are added to automatically reconstruct data for visualisation of the complete vascular tree from the aortic arch down to the pedal arch in the feet. The MobiView SmartLine step has a manual start to enable the windowing of images prior to fusing the datasets and the generation of the new image series.

MIPs (maximum intensity projections) from subtracted datasets

MIP of abdomen station The subtracted and enhanced images of the abdomen station are post-processed in the VolumeView package. A MIP with 35 images is generated as a radial stack.MIP of pelvis station The subtracted and enhanced images of the pelvis station are post-processed in the VolumeView package. A MIP with 35 images is generated as a radial stack.MIP of tibia station The subtracted and enhanced images of the tibia station are post-processed in the VolumeView package. A MIP with 35 images is generated as a radial stack.

Peripheral arterial CE MR angiography MobiView MIP projections

The MIPs of the three stations are ready to be fused in the MobiView package. In the following you see a selection of images fused in MobiView and a movie of the complete MobiView data.

Patient preparation and positioning

Position the patient feet first on the patient support equipped with the Tabletop Extender. 

For the contrast injection a venous access needs to be available.

Before the patient is placed in the isocenter of the magnet, the arms are raised and fixated beside the head. 

Provide the patient with the hearing protection and the nurse call.

Lightvisor on the middle of the lower leg.

Contrast agent

Refer to the contrast agent manufacturer for information on dose and indications for use. 

It is used for the BolusTrak and the following MobiFlex 3D scans.

Postprocessing

Automated SmartLine postprocessing steps are added to the different scans:

  • Surveys, VolumeView MIP
  • Pre- and post-contrast stations, ImageAlgebra subtraction
  • Post-contrast stations, VolumeView MIP
  • Post-contrast MIPs of different stations, PicturePlus

In addition, MobiView SmartLine steps are added with a manual start to fuse the MIPs of the surveys and the enhanced MIPs of the different stations. Herewith, user interaction is enabled to allow for adaption of the WW and WL of the different stations before image series are fused and a new image series is generated.
