MR-guided stereotactic body radiation therapy for primary cardiac sarcomas
Abstract Background Primary cardiac tumors are an extremely rare disease with limited prognosis. The treatment of choice is surgery. Other treatment options include chemotherapy and radiation therapy, which historically represented a palliative approach in patients who were not eligible for surgery....
