MRI-Assisted Radiosurgery—the Most Advanced Form of Brachytherapy1

MRI-assisted radiosurgery (MARS) represents an exciting new horizon in prostate brachytherapy. The high-resolution images produced by magnetic resonance imaging (MRI) allow for unprecedented accuracy of implant planning and post-implant evaluation.

Pair Cesium Blu (Cs-131), Isoray’s high-energy isotope, with Sirius®, the only positive-signal MRI Marker for quality assurance in high-precision brachytherapy. This FDA-cleared pairing gives you a clear picture of every implant, delivering the accuracy you need, and the high-quality treatment your patients deserve.

Blu Tray

Isoray’s Blu Tray delivery system empowers clinicians by organizing and measuring Cesium Blu Strands while in the OR. 

Surgical

With higher energy and a shorter half-life than competitors, Cesium Blu has been used in the treatment of brain, colorectal, gynecological, and head and neck cancers.

Modern brachytherapy starts here.

Not all brachytherapy radioisotopes are the same. Cesium Blu, Cs-131, offers you a powerful option for treating prostate and other cancers throughout the body.

Higher Energy

Isoray’s proprietary isotope, Cesium Blu, has a higher energy allowing for a more uniform dose distribution with less overdosing than other permanent isotopes. (1)

Shorter Half-Life

Isoray’s proprietary isotope, Cesium Blu, has a shorter half-life than other commonly used isotopes for the treatment of cancer throughout the body, resulting in a shorter duration of radiation which contributes to a rapid resolution of patient side effects. (2)

Improved Coverage of the Prostate

Isoray’s Cesium Blu proprietary permanent prostate cancer brachytherapy seeds allow for better dose homogeneity and the sparing of the urethra and rectum while providing comparable prostate coverage compared to other seeds with comparable or fewer seeds and needles. (3, 4, 5, 6)

Rapid Resolution of Side effects

Isoray’s proprietary isotope, Cesium Blu, has a shorter half-life than other commonly used isotopes for the treatment of cancer throughout the body, resulting in a shorter duration of radiation which contributes to a rapid resolution of patient side effects. (7, 8, 9, 10)

Higher Biologically Effective Dose

Isoray’s Cesium Blu also delivers a higher “biological effective dose” or BED compared to I-125 or Pd-103 across a wide range of tumor types. (11)

PSA Control

Isoray along with investigators tracking PSA in both single arm and randomized prostate cancer treatment trials have concluded that Cesium Blu’s PSA response rates have similar early tumor control to I-125, which was previously considered the gold standard in permanent seed brachytherapy. (8, 12, 13)
