Spine imaging of challenging patients using Ingenia

Application Tip
van Loon, Lars, R.T. Philips Healthcare • Netherlands
Hopkins, Wendy, R.T. Philips Healthcare • Netherlands

Ingenia is designed for simplified, fast workflow. Ingenia makes it easy to scan challenging patients, especially in the clinical area of the spine. Not everyone is able to lie completely flat in the MR for a study. For patients with kyphosis or those who have difficulty swallowing or breathing when lying flat, it can be very challenging to lie still for the time it takes to achieve a high quality exam. That’s why we need a solution to image these patients without a significant trade-off in resolution and/or scan time.

Tip 1: Spine imaging with tilted dS HeadNeckSpine coil solution

The FlexTilt coil tilting device is designed for patients who do not like to be closed in, such as patients suffering from claustrophobia, and for patients who just can’t lie flat. FlexTilt provides an alternative way to image these challenging patients with easy, fast positioning and scanning. The tilting device works with either the dS HeadSpine or dS HeadNeckSpine coil solutions. It allows tilting the dS HeadNeckSpine coil in increments from 0-20 degrees. FlexTilt is designed to accommodate claustrophobic patients and patients with kyphotic spines for instance, who could not comfortably tolerate imaging previously.

Tip 2: Use SmartExam with tilted dS HeadNeckSpine solution

It is possible to use SmartExam with the tilted dS HeadNeckSpine solution to obtain excellent automatic planning and automatic numbering of vertebrae.

Tip 3: Fast Cervical Spine imaging in 8 minutes

dStream digitizes the signal directly in the coil at the patient, which provides higher SNR and signal fidelity than a (partly) analog pathway. This increase in SNR can be used for faster scanning, while still maintaining superb resolution. A full, high-resolution cervical spine study can be completed within 8 minutes. A transverse cervical spine (C2-T1) is included in this protocol. The fast cervical spine ExamCards are available in the scanner database for Ingenia 1.5T and 3.0T.

Tip 4: Fast imaging of the complete spine in two stations

Because of the Xtend imaging space there is outstanding magnet homogeneity delivering a homogenous field of view up to 55 x 55 x 50 cm, making it possible to perform 2-station total spine exams instead of 3-station total spine exams, both on 1.5T and 3.0T. On Ingenia, this

procedure does not require any coil or cable handling; the patient simply needs to lie down on the table and positioning is done, fast and easy.


In addition, with SmartSelect the technologist no longer needs to select coil elements; it is done automatically. SmartSelect picks the most optimal channels needed to provide the best SNR in the chosen FOV of the exam, to help get a first-time-right exam and may reduce re-scans. The 2-station total spine ExamCards are available in the scanner database for Ingenia 1.5T and 3.0T.
