Tips for fast and easy acute brain imaging on Ingenia system

Application Tip
Nijenhuis, Marco Philips Healthcare Philips Global
Heinlein, Jeremy, R.T. Philips Healthcare Philips Global

The Ingenia MR scanner is designed for image clarity and simplified, fast workflow - just what is needed in acute brain exams. When patients can't lie still for long and results are urgently needed, patient comfort should be optimized, scans should be fast and robust, and image quality needs to be consistent and reliable.

Tip 1: Very easy patient preparation with dS HeadNeckSpine coil solution

Use the new dS HeadNeckSpine coil solution. It offers a more comfortable, open experience for patients, often important in acute brain scans, as many of these patients are restless and anxious and sometimes very confused.

Connect the dS HeadNeckSpine coil solution on the table. Only one hand is needed for this as the connector is small and lightweight, since it only contains one digitizer supply cable and a fiber optic cable for fast and undisturbed data transfer. The FlexCoverage posterior coil is integrated under the table and does not need manipulation.

The flexible, open coil design enhances patient comfort with a visual field and extra space, so the nose doesn't touch the coil. The coil's anterior flap can be raised or lowered to increase comfort and proximity of elements to the patient leading to clearly better SNR in the area underneath of the neck.

If a FlexTrak patient transport system is used, the technologist can easier focus on the patient, as the auto-eject functionality does not require a manual unplugging of coil connectors when lowering the tabletop using FlexTrak.

Tip 2: Trade higher SNR to speed up

Ingenia features dStream RF architecture and dStream coils. The direct digital sampling in the coil provides higher SNR and signal fidelity. In acute brain exams, this gain in SNR can be traded in for higher scan speed. A scan time of less than eight minutes can be achieved by reducing NSA and using SENSE. With current parallel imaging techniques noise breakthrough can be seen with high factors. Now with Ingenia, the new dS-SENSE allows high factors with excellent results.

Tip 3: SmartSelect automatic coil element selection

Coil selection is no longer necessary during scan setup. When the FOV is planned, the system automatically selects the coil elements in the dS HeadNeckSpine coil solution delivering the best possible SNR for the scans.

Tip 4: Setting up the ExamCard

In an ExamCard for an acute brain, scan time should be reduced as much as possible without sacrificing image quality. The increased SNR realized by Ingenia allows the use of higher parallel imaging factors due to the new dS-SENSE algorithm. The Ingenia fast brain ExamCard makes use of higher parallel imaging factors to minimize scan time while maintaining good image quality. It includes:
 FLAIR DWI b=1000
DWI b=1000
 MRA transverse MIP Dynamic
MRA transverse MIP

Tip 5: Higher SENSE factors can be used

Use of a dS-SENSE factor will accelerate a scan by that factor. If SENSE factors are too high, noise will become too high. Ingenia with dStream allows for use of higher factors while still preserving SNR. These multislice T2 TSE images with increasing SENSE factors from 1 to 3 illustrate this.

Tip 6: 3D BrainView

The 3D BrainView high resolution acquisition enables reformatting of any other orientations after the scan. The scan has no slice gap, so a FLAIR series is ideal to visualize, for instance, small white matter lesions in any desired plane.

The image example below shows a comparison between multislice FLAIR and 3D BrainView FLAIR.
