Tips for quick and easy whole body scanning with Ingenia

Application Tip
Stout, Jeroen Philips Healthcare

Philips' digital broadband MR system Ingenia facilitates outstanding whole body imaging. The Xtend imaging space delivers outstanding homogeneity on a 70 cm bore. The dStream architecture and coils enable high image quality, faster scanning and improved workflow.

Tip 1: Patient positioning and coil choice

Patient positioning has become faster and easier with dStream's FlexCoverage posterior coil covering from "neck to toe" for feet-first or head-first imaging without any coil manipulation. By adding the dS HeadNeck coil solution and a single FlexCoverage anterior coil "eyes to thighs" oncology coverage is achieved. To obtain total body "head to toe" coverage just add one additional FlexCoverage anterior coil.

Positioning the wireless VCG/respiratory belt does not require connector and cable handling. No tabletop extender is needed, so whole body scanning can be performed faster and can easily be added to an exam. The table stroke is over 2 meters (6.6 feet).

The FlexCoverage anterior coils are easy to handle as they are lightweight and very flexible thanks to the use of fiber optic cables. The dStream coils enable easy one-hand connector plug-in. The coil is designed for strap-free use. However, strapping may be done to prevent unwanted coil movement.

Tip 2: SmartSelect automatic coil element selection for best SNR

Manual coil selection is not needed. Ingenia's SmartSelect automatically selects the coils and coil elements which contribute to the highest SNR. So, no matter what coils are connected or what size the patient is, the system determines per station what the best coil elements are.

This is designed for enhanced ease of use and improved reproducibility and consistency between scans.

Tip 3: Planning a full whole body exam in only 5 stations

ExamCards already ensured a smooth workflow, but this is now further optimized since reference scans and coil survey scans are automatically performed by the system.

The large FOV in FH direction enabled by Ingenia allows acquisition of a full high quality whole body scan in only 5 stations. Compared to the 7 or 8 stations that were usually required on older systems, this considerably reduces exam time because it involves fewer table movements and thus decreased scan times.

Tip 4: Use higher parallel imaging factors to optimize resolution per station

The use of digital RF coils - with signal digitization in the coil - improves SNR and thus enables parallel imaging with higher dS-SENSE factors. This speeds up whole body scans and helps to sharpen images. For instance, a SENSE factor of 4 in LR direction is now achieved.

In addition, it is possible to tailor the spatial resolution per station in whole body imaging. The dStream architecture makes use of higher parallel imaging factors practical, enabling flexible optimization of the resolution per station to obtain improved diagnostic image quality in all stations.

Tip 5: A 15-minute Ingenia 1.5T whole body exam

This example shows a high resolution whole body exam including single shot T2-weighted TSE and free breathing whole body DWI (DWIBS). Reconstructed voxel sizes are 1 x 1 x 6 mm in the whole body scan. In DWIBS voxels are 5 x 5 x 6 mm. The total exam time is 15 minutes.
