Aktueller Stand der MR-gesteuerten Prostata-Interventionen

Zusammenfassung

In den letzen Jahren spielt die MRT in der Diagnostik und Therapie des Prostatakarzinoms eine immer wichtigere Rolle. Die MRT erlaubt neben der Abgrenzung der anatomischen Strukturen auch die Lokalisation möglicher Tumoren durch die Verwendung von T 2-gewichteten Sequenzen, der Spektroskopie sowie dynamischer Untersuchungen. Die gute Abgrenzbarkeit der Tumoren erlaubt eine sichere Durchführung von Prostatainterventionen, wie Biopsien, Brachytherapie oder verschiedenen lokalen Thermotherapien. Durch den zusätzlichen Einsatz von Robotersystemen kann die Genauigkeit der Interventionen erhöht werden. Aufgrund der Vorteile der MR-Bildgebung ist zu erwarten, dass MR-gesteuerte Prostatainterventionen in der Zukunft eine zunehmende Rolle spielen werden.

Abstract

In recent years MR imaging has played an increasingly important role in the diagnosis and treatment of prostate cancer. MR imaging of the prostate allows clear delineation of the anatomic structures and prostate tumors using T 2-weighted images combined with spectroscopy and dynamic examinations. The advantages of MRI make it possible to perform interventions, like biopsies, brachytherapy or different local therapies of the prostate gland. MRI robotic assistance will improve the accuracy of the interventions. Due to the advantages of MR imaging, MR-guided prostate interventions will play a greater role in the future.
