Now we can really deliver ablative doses in those complex cases of multiple metastases from renal cell carcinoma in the pancreas, which is not possible on conventional treatment machines.
MR-guided radiation therapy for oligometastatic disease treatment
Treat small targets with certainty
Local ablative therapy for hard-to-treat targets
Oligometastases are metastatic tumors, limited in number and location, for which local ablative therapy could be curative. These small, often mobile, soft tissue tumors can be hard to see at the time of treatment with conventional imaging techniques, making them difficult to target accurately. As a result, they are often treated using systemic therapy with its many associated side effects.
MR-guided radiation therapy allows you to see small oligometastases and surrounding anatomy as you treat, enabling you to deliver ablative doses to hard-to-treat oligometastases accurately and with small margins. With Elekta Unity you can:
See clearly to make precise local ablative therapy possible for hard-to-treat oligometastases.
Clinical benefits
Elekta Unity MR-guided radiation therapy for oligometastatic disease treatment
With exquisite soft tissue visualization, online plan adaptation and comprehensive motion management, Elekta Unity allows you to:
- Deliver highly conformal ablative doses with extreme accuracy
- Spare healthy tissue and reduce side effects
- Increase patient eligibility for radiation therapy
- Avoid surgery and reduce systemic therapy for small targets
- Deliver SBRT–even single fraction RT–with certainty
See the difference for patients with oligometastatic disease
Enhance small target visibility
Optimized MRI sequences on Elekta Unity enable you to see otherwise difficult-to-visualize structures, such as small lymph node oligometastases, before and during treatment, allowing you to treat them with certainty.

Account for motion
Comprehensive Motion Management accounts for motion and daily anatomical changes, allowing you to deliver SBRT with certainty to oligometastases in the upper abdomen. The ability to reduce margins to just 2 mm (see this case) spares healthy tissue and reduces side effects.

Protect nearby organs
Steep modulated dose gradients protect nearby organs at risk while exquisite target visualization and online plan adaptation ensure optimal PTV coverage for SBRT to oligometastases.

Adapt to changes in anatomy
Elekta Unity maximizes patient eligibility for radiation therapy. Online plan adaptation accounts for daily changes in anatomy, such as bladder or bowel filling, and allows the use of smaller margins to protect healthy tissue.
