Map the blood supply
Angiography and a simulation study show the liver’s arterial anatomy and help estimate where treatment particles may travel.
Y-90 Radioembolization · Los Angeles
Internal radiation, planned around your liver and cancer care.
EVSLA reviews your diagnosis, imaging, liver function, prior treatment, and oncology plan to determine whether Y-90 may belong in your care.
Y-90 is for selected patients and tumors. An evaluation does not guarantee candidacy, response, or a specific treatment outcome.

Microspheres travel through selected liver arteries.
Anatomy and particle flow are evaluated first.
Treatment should support the broader oncology plan.
The answer depends on more than the scan. A specialist weighs the tumor, the liver, and the full cancer-care strategy before recommending treatment.
Y-90 may be discussed for selected primary liver cancers or cancer that has spread to the liver.
Number, size, location, distribution, and arterial anatomy all shape what is technically possible.
Blood tests, cirrhosis, prior liver treatment, and how much healthy liver would be exposed matter.
The team considers disease outside the liver, other treatment options, timing, health, and your goals.
The procedure delivers microscopic beads containing yttrium-90 through the arteries that feed selected tumors. The radiation acts over a short distance around each microsphere.
Angiography and a simulation study show the liver’s arterial anatomy and help estimate where treatment particles may travel.
Using live X-ray imaging, the specialist advances a thin catheter into the selected artery supplying the treatment area.
Y-90 microspheres flow into the selected tumor territory and release radiation locally while treatment is planned to limit exposure elsewhere.
Y-90 usually begins with a planning procedure, followed by treatment. Some patients need more than one treatment session, and timing varies.
The team reviews imaging and labs, maps the arteries, and performs a simulation to help plan the treatment area and dose.
If mapping supports treatment, the physician returns to the selected artery and delivers the prescribed Y-90 microspheres.
Follow-up covers symptoms, liver tests, individualized radiation-safety instructions, and imaging to assess the treated area.
Your specialist evaluates the imaging, arterial anatomy, liver function, and treatment goal before recommending Y-90 or another next step.

Clear answers about treatment, mapping, recovery, and how Y-90 fits cancer care.
Y-90 is an image-guided internal radiation treatment. An interventional radiologist advances a thin catheter into selected liver arteries and delivers microscopic beads containing yttrium-90 to the tumor’s blood supply. The radiation acts over a short distance around the beads.
Y-90 may be considered for selected primary liver cancers and selected cancers that have spread to the liver. Eligibility depends on the diagnosis, tumor number and location, liver function, arterial anatomy, overall disease burden, prior treatment, health, and goals of care.
Mapping defines the liver’s arterial anatomy and helps estimate where treatment particles may travel, including whether too much could reach the lungs or another organ. The result guides dose and catheter planning and may show that Y-90 is not appropriate.
No. Y-90 uses internal radiation carried by microspheres. TACE delivers chemotherapy through liver arteries. Both are liver-directed treatments, but they work differently and are not interchangeable.
Fatigue, nausea, reduced appetite, fever, or abdominal discomfort can occur. Other risks include access-site bleeding or bruising, vessel injury, infection, contrast or medication reaction, liver injury, and rare non-target radiation injury involving the stomach, bowel, gallbladder, or lungs. Discharge timing, activity limits, and radiation-safety instructions are individualized.
Sometimes. Y-90 may be one part of a plan that also involves systemic therapy, surgery, transplant evaluation, ablation, external radiation, another embolization treatment, or observation. The sequence depends on the tumor, liver function, overall disease, and treatment goal.
Share your current imaging, diagnosis, recent lab results, and oncology plan. EVSLA can review the full picture and explain whether Y-90—or another liver-directed option—makes sense to discuss.
