Advances in radiotherapy planning reduced the volumes of irradiated normal tissue and allowed safe dose escalation in prostate cancer. Image-guided radiotherapy solutions to prostate and bladder cancer offer further improvements. The initial process is understanding the causes and extent of internal organ motion, followed by development of equipment and protocols to minimise geographical miss. ...

It is important to monitor tumor movement during radiotherapy. Respiration-induced motion affects tumors in the thorax and abdomen (in particular, those located in the lung region). For image-guided radiotherapy (IGRT) systems, it is desirable to minimize imaging dose, so external surrogates are used to infer the internal tumor motion between image acquisitions. This process relies on consisten...

Background. In patients with hepatocellular carcinoma, selection criteria for transarterial hepatic selective internal radiotherapy are imprecise. Additionally, radiographic parameters to predict outcome of transarterial hepatic selective internal radiotherapy have not been fully characterized. Patients and methods. Computed tomography (CT) scans of 23 patients with unresectable primary hepatoc...

Current progress in nanomedicine has exploited the possibility of designing tumor-targeted nanocarriers being able to deliver radionuclide payloads in a site or molecular selective manner to improve the efficacy and safety of cancer imaging and therapy. Radionuclides of auger electron-, alpha-, beta-, and gamma-radiation emitters have been surface-bioconjugated or after-loaded in nanoparticles ...
