Description

The ExamCard describes a fast knee imaging protocol that offers a routine knee protocol in a scan time of just 7:00 minutes. Using 3-mm slices and a FOV of 15 to 16 cm with a 256 acquisition matrix, spatial resolution is equal to that obtained routinely at 1.5 T but with significantly shorter imaging times.

 

The fast imaging times can be particularly useful in patients that are in pain and have problems with keeping motionless for a long time.

 

The examination includes sagittal T1- and T2-weighted series and sagittal and coronal fat suppressed proton density examinations. Fat suppression is achieved using the SPAIR prepulse that is insensitive to variations in the B1-field, and gives a homogeneous low fat signal in the entire field-of-view.

 

All sagittal scans share the same geoname. The planning of the first sagittal series is therefore automatically propagated to the other sagittal sequences.

Patient preparation

The patient is imaged in supine position and enters the magnet feet first. Protocols are meant for use with the 8-channel SENSE-Knee coil.
