Radiation Therapy Radiation
Therapy & Imaging Center Many patients receive radiation therapy - a high-energy x-ray - to slow, stop or destroy cancer cells so they are unable to grow and multiply. It can be used for delicate locations such as the vocal cords and to control early cancers without surgery. It can also be used to shrink a tumor before surgery or after surgery to destroy any remaining cancer cells in the area. It is frequently used in conjunction with chemotherapy to make both forms of treatment more effective. The goal of radiation treatment of tumors is to deliver a lethal dose of radiation to the tumor while sparing nearby healthy structures. After the completion of the treatment, most patients can resume their daily normal life. Computed Tomography (CT) CT scanning is a computerized X-ray technique that enables radiologists to identify blockages, abnormal growths or other disease processes. Intensity Modulated Radiation Therapy (IMRT) CRMC is the only medical facility in Jefferson City to offer Intensity Modulated Radiation Therapy (IMRT). In fact, this ultra-sophisticated technique is only offered by 36 percent of the radiation therapy programs in the United States. This new technology allows radiation oncologists to match the radiation dose to the shape and location of the tumor, thus avoiding damage to the surrounding healthy tissue and organs. According to "The Oncologist Online," IMRT holds the promise in radiation oncology in the new century.
Magnetic Resonance Imaging (MRI) Magnetic resonance imaging (MRI) is an advanced imaging technique that uses a powerful magnet and a highly advanced computer system to produce an image similar to a 'slice' through the human body. The result is very accurate diagnostic pictures that assist your physician in developing your personalized treatment plan. Positron Emission Tomography (PET) PET has revolutionized the way tissue function is studied. PET scans pick up faster growing cells and display them as abnormal areas on the image. It is the most accurate tool available in showing the presence or spread of many cancers. This test enables your doctor to develop an appropriate treatment plan. PET/CT PET/CT combines the fastest and most sophisticated CT scanner with the most advanced PET system. Together a PET/CT scan allows doctors to view metabolic activity and pinpoint where abnormal lesions are located so they can target the disease. Radiofrequency Ablation (RFA) RFA is a minimally invasive procedure, used in conjunction
with chemotherapy, in which the interventional radiologist places a slender
probe directly into the tumor. This ensures that treatment will focus on the
diseased area. Once the probe is in position, a bouquet of very thin, flexible
electrodes are extended from the end of the probe into the tissue. Using a radiofrequency
generator, the physician then allows a carefully controlled amount of energy
to flow through the electrodes into the tissue. When all cells within the lesion,
as well as a margin around it, are heated for a predetermined length of time,
the procedure is complete. This results in a reduction of the size or elimination
of the tumor. RFA can be considered as a treatment option for most patients
with liver cancer, colorectal cancer and bone metastases.
