This Multiva 1.5T Release 5.1.7 ExamCard, created by the Bay-Tuna Radiology Center at the Beyhekim Devlet (MOH) Hospital in Konya, is used for femur or tibia imaging. Coronal, transverse and sagittal scans have been optimized for large coverage in short scan times realized by using SENSE. The SENSE Torso 16ch coil in combination with the SENSE HeadSpine 16ch coil is used for scanning.
The coronal scans make use of a large field of view (FOV) to cover both legs including two joints. For femur imaging, the FOV in head feet direction has been defined to cover the anatomy from the hip joint to the knee joint, shown in the images below. For tibia imaging the coverage of the FOV in head feet direction includes the knee joint down to the ankle joint. The transverse scans are positioned over both legs in left right direction and from joint to joint in head feet direction. The sagittal scan covers one leg only from left to right and joint to joint coverage in head feet direction.

Position the patient feet first on the HeadSpine-16ch coil. In addition, the SENSE Torso-16ch coil is placed on top of the legs:
- For femur imaging make sure that the SENSE Torso-16ch coil is positioned to cover both the hip and knee joints.
- For tibia imaging make sure that the knee and ankle joints are covered by the SENSE Torso-16ch coil.
To reduce potential movement of the patients legs make use of wedges and straps delivered with the system. Provide the patient with hearing protection and the nurse call.
The light visor position:
- For femur imaging is on the middle of the upper leg.
- For tibia imaging is on the middle of the lower leg.
