Iodine-131 (I-131) is a radioactive substance produced in nuclear reactors that provides the medical isotope for nuclear medicine procedures. At high therapeutic doses, radioisotopes can be injected intravenously to effectively penetrate and destroy tumor tissue through localized radiation. Your healthcare provider will take steps to protect your thyroid from medication. Radioactive isotopes also release gamma particles, which can be captured by specialized gamma cameras during a molecular imaging process called scintigraphy. I-131 can be combined with molecular compounds to further personalize treatment and isolate radiotherapy to specific cells and their physiological functions. I-131 radiation therapy is a treatment for hyperthyroidism and thyroid cancer. For thyroid cancer, I-131 radiation therapy is usually given after thyroid removal surgery to destroy any remaining cancerous or healthy thyroid tissue. In I-131 radiation therapy, the radioactive substance used is radioactive iodine I-131. Patients swallow r

Physical Therapist Ultrasound Machine Physical therapist ultrasound machine is commonly used in physical therapy to aid in the treatment of musculoskeletal conditions. Ultrasound therapy is a non-invasive treatment that utilizes sound waves to generate heat within the body's tissues, promoting healing and reducing pain and inflammation. Physical therapist ultrasound machine is particularly beneficial for physical therapists, as they allow for the treatment to be performed in the patient's home or office, rather than requiring them to come into a clinical setting. This can make therapy more convenient and accessible for patients, and may also help to reduce healthcare costs. Physical therapist ultrasound machine is one of the most common methods used by clinicians and uses high frequency acoustic vibrations to produce thermal (increased local blood flow, cellular metabolism, connective tissue malleability and pain relief) and non-thermal (tissue regeneration and wound healing - protein and collagen synthesis, cell membrane changes) effects on body tissues. Targeted sound waves can produce deep tissue heating for soft tissue malleability, injury repair and pain relief.
