oZTEo for MR bone imaging

With this new application for imaging cortical bone surfaces, based on the radial Zero TE (ZTE) application, you can be a one-stop shop for bone imaging and add considerable clinical value to your orthopedic exams.

Symposium about oZTEo clinical experience

In our experience, the routine use of ZTE has made it possible to highlight bone pathologies or the presence of calcifications. Our MR exams have become more efficient since they now combine the usual soft tissue differentiation of conventional MR with the almost CT-like appearance of ZTE.

Cortical bone information perfectly co-registered with the soft tissue series

oZTEo enables a sharp contrast between cortical bone and surrounding soft tissue.

Glenoid fracture

With minimal effort, MR oZTEo bone images can be thresholded and 3D rendered to show a striking resemblance to CT.

Ossification of Longitudinal Ligament

In this clinical MR case, the soft tissue images showed apparent disc bulges and protrusions at multiple levels. However, the oZTEo images showed something significantly different – massive ossification of the posterior longitudinal ligament and osteophyte formation. The results impacted the choice of surgical approach.

Geometric measurements with oZTEo

oZTEo images can be used for geometric and morphologic measurements,such as in routine FAI in the hip. These results have been published in The American Journal of Sports Medicine, 2019: 47(14): 3460-3468. https://doi.org/10.1177/0363546519878170

3D oZTEo for MR bone imaging

Images can be viewed in 2D reformats or 3D volume rendered with Volume Illumination

oZTEo complements the MR soft tissue exam

With a few additional minutes, oZTEo can dramatically increase the clinical value of the MR exam.

oZTEo for rheumatology

In this clinical case, oZTEo shows a characteristic “punch out” erosion (yellow arrow) with sclerotic margins that is indicative of gout. Also, calcification within the soft-tissue mass (blue arrows) which represents tophaceous deposit or urate crystals seen in chronic gout.

Product benefits

Powerful bone imaging for all anatomies

Available for all anatomies without ionizing radiation, oZTEo delivers images of bone morphology, calcification, ossification and fractures. oZTEo complements conventional MR soft tissue exams with perfect co-registration and provides 3D isotropic imaging using a radial ZTE acquisition, with inherent motion insensitivity. Use oZTEo with Volume Illumination for realistic 3D rendering.

One-stop orthopedic shop

When oZTEo is included in an MR exam, cortical bone information is perfectly co-registered with the soft tissue series, making it a one-stop imaging shop for most routine MSK needs.

Sharp contrast

CT-like image contrast without ionizing radiation

MR bone imaging provides a CT-like image contrast without ionizing radiation, making it an attractive alternative for pediatric and pregnant patients where ionizing radiation is a concern. In addition, it provides a welcome alternative when longitudinal CTs are required, particularly when low-dose CT systems are unavailable.

Ease patient burden

Save time and costs

Imaging facilities can prioritize their use of CT for more emergent cases. Having both soft tissue assessment and bone imaging within the same exam can lessen the burden on the patient to attend two separate imaging modality appointments and may also lead to reduced healthcare costs.

In many cases, using oZTEo will spare the patient the time, radiation exposure, multiple visits and cost.
