SpaceOAR Vue Hydrogel 3D Model
SpaceOAR Vue is a radiopaque hydrogel spacer that offers enhanced visiblitiy via CT scan, potentially helping physicians improve contouring accuracy and consistently position patients receiving prostate cancer radiation.1

What is the benefit of hydrogel spacing and a radiopaque perirectal spacer?
SpaceOAR Hydrogel is an absorbable hydrogel that temporarily creates space between the prostate and rectum, designed to reduce the radiation dose delivered to the rectum during prostate cancer radiation therapy.
The enhanced visibility on a CT scan is designed to help physicians improve contouring accuracy of the prostate and rectum, potentially leading to more accurate treatment plan creations when compared to SpaceOAR™ Hydrogel. This may reduce the overall treatment costs per patient, time required to fuse CT and MRI images, and the hospital staff’s time spent in obtaining MRI reimbursement authorisation. 

Potential Operational Benefits

With the improved visibility of SpaceOAR Vue Hydrogel on a CT scan, adepartment’s clinical workflow may be improved as the patient will not need a post-procedural MRI for treatment planning.

Potential Clinical Benefits

For CT planning, physician-delineated prostate volume can be on average 15% smaller (under contouring) or 30% larger (over contouring) than the “true” prostate volume. With SpaceOAR Vue Hydrogel, you may be able to contour the prostate and rectum without the need for an additional MRI. This may also reduce any contouring inaccuracies, potentially leading to more accurate treatment plan creations. Accurate and consistent positioning of the patient from one fraction to the next is important to physicians, to ensure that treatment is delivered according to plan. CT radiopacity may provide an effective imaging option to MRI for patients with implanted metallic devices so you can care for a broader population of prostate cancer patients.

SpaceOAR and SpaceOAR Vue Hydrogels are intended to temporarily position the anterior rectal wall away from the prostate during radiotherapy for prostate cancer and in creating this space it is the intent of SpaceOAR and SpaceOAR Vue Hydrogels to reduce the radiation dose delivered to the anterior rectum. As with any medical treatment, there are some risks involved with the use of SpaceOAR and SpaceOAR Vue Hydrogels. Potential complications associated with SpaceOAR and SpaceOAR Vue Hydrogels include, but are not limited to: pain associated with SpaceOAR and SpaceOAR Vue Hydrogels injection; pain or discomfort associated with SpaceOAR and SpaceOAR Vue Hydrogels; needle penetration of the bladder, prostate, rectal wall, rectum or urethra; injection of SpaceOAR and SpaceOAR Vue Hydrogels into the bladder, prostate, rectal wall, rectum or urethra; local inflammatory reactions; infection; injection of air, fluid or SpaceOAR and SpaceOAR Vue Hydrogels intravascularly; urinary retention; rectal mucosal damage, ulcers, necrosis; bleeding; and rectal urgency.
