Médecine Nucléaire et Radiothérapie

Radiation therapy stands as a cornerstone in the arsenal against cancer, offering a potent tool in the fight for healing. Its ability to target and
eradicate cancerous cells while sparing healthy tissue has revolutionized oncology treatment. This article delves into the profound impact of
radiation therapy, exploring its mechanisms, advancements, and transformative role in unlocking healing for patients worldwide. Radiation therapy,
also known as radiotherapy, utilizes high-energy rays or particles to damage cancer cells' DNA, impeding their ability to multiply and survive. Unlike
chemotherapy, which circulates throughout the body, radiation therapy precisely targets tumors, minimizing collateral damage to surrounding
healthy tissue. This precision is crucial in mitigating side effects and enhancing treatment efficacy. One of radiation therapy's defining features
is its precision. Advanced imaging technologies such as MRI, CT scans, and PET scans enable oncologists to precisely locate tumors and tailor
treatment plans accordingly. Techniques like intensity-modulated radiation therapy stereotactic radiosurgery and proton therapy further enhance
precision, allowing for highly localized delivery of radiation while sparing nearby organs and tissues.

The Marine-Lenhart syndrome is a rare disorder defined by the association or successive occurrence of Basedow's disease and autonomous thyroid nodules. This form is responsible for persistent hyperthyroidism requiring special treatment. Nuclear medicine contributes to the detection of this syndrome by means of thyroid scintigraphy, which allows its diagnosis by showing a hyperfixing parenchyma that is not inhibited by the presence of toxic nodules. Additionally, radioactive therapy is generally administered at higher doses, as this form is particularly resistant to standard treatment.
