Patient preparation

Prepare the patient according to the PI-RADS version 2 recommendations.

 

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

 

Position the patient head or feet first in the 32ch SENSE Cardiac coil under consideration of the patient height and the requirement that the region of interest (pelvis/prostate) must reach isocenter.

 

Before positioning the patient in isocenter, raise the arms above the head. 

Provide the patient with hearing protection and the nurse call.

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 eTHRIVE dynamic scans.

Postprocessing

SmartLine postprocessing steps,

 

  • PicturePlus, have been added to the T2W TSE VISTA and T2W_TSE scans to enhance the image contrasts.
  • Diffusion Registration and Diffusion ADC have been added to the DWI_SSh.

The SmartLine steps start automatically without user interaction after the reconstruction of the original image series.
