Планирование лучевой терапии на основе магнитно-резонансной томографии: первые шаги

Планирование лучевой терапии – сложный процесс, который включает использование современных трехмерных диагностических методик – компьютерной томографии (КТ) и магнитнорезонансной томографии (МРТ). При создании лечебного плана обязательно используют КТ, которая позволяет собрать данные об электронной плотности облучаемого объема и применить их в расчетах дозного распределения. Более точно определить границы многих опухолей позволяет МРТ. В статье представлена методика получения псевдо-КТ-изображений для планирования лучевой терапии на основе МРТ без использования КТ. В исследование вошло 7 пациентов с диагнозом «медуллобластома», которые перед лучевой терапией проходили диагностику на МРТ с идентичными параметрами сканирования и КТ. Первые результаты, полученные при использовании данной методики, показывают перспективность применения исключительно МРТ при планировании лучевой терапии.
