3D tumour spheroids for the prediction of the effects of radiation and hyperthermia treatments.
Brüningk, SC; Rivens, I; Box, C; Oelfke, U; Ter Haar, G (NATURE PUBLISHING GROUP, 2020-02-03)For multimodality therapies such as the combination of hyperthermia and radiation, quantification of biological effects is key for dose prescription and response prediction. Tumour spheroids have a microenvironment that ... -
A Polyvinyl Alcohol-Based Thermochromic Material for Ultrasound Therapy Phantoms.
Ambrogio, S; Baêsso, RDM; Gomis, A; Rivens, I; Haar, GT; et al. (ELSEVIER SCIENCE INC, 2020-11-01)Temperature estimation is a fundamental step in assessment of the efficacy of thermal therapy. A thermochromic material sensitive within the temperature range 52.5°C-75°C has been developed. The material is based on polyvinyl ... -
A study of thermal dose-induced autophagy, apoptosis and necroptosis in colon cancer cells.
Mouratidis, PXE; Rivens, I; Ter Haar, G (TAYLOR & FRANCIS LTD, 2015-07-04)PURPOSE: The pleiotropic effects of heat on cancer cells have been well documented. The biological effects seen depend on the temperature applied, and the heating duration. In this study we investigate the cytotoxic effects ... -
Combining radiation with hyperthermia: a multiscale model informed by in vitro experiments.
Brüningk, S; Powathil, G; Ziegenhein, P; Ijaz, J; Rivens, I; et al. (ROYAL SOC, 2018-01-01)Combined radiotherapy and hyperthermia offer great potential for the successful treatment of radio-resistant tumours through thermo-radiosensitization. Tumour response heterogeneity, due to intrinsic, or micro-environmentally ... -
Comparison of Imaging Changes and Pain Responses in Patients with Intra- or Extraosseous Bone Metastases Treated Palliatively with Magnetic Resonance-Guided High-Intensity-Focused Ultrasound.
Giles, SL; Brown, MRD; Rivens, I; Deppe, M; Huisman, M; et al. (ELSEVIER SCIENCE INC, 2019-02-21)PURPOSE: This study compared changes in imaging and in pain relief between patients with intraosseous, as opposed to extraosseous bone metastases. Both groups were treated palliatively with magnetic resonance-guided ... -
Equivalence of cell survival data for radiation dose and thermal dose in ablative treatments: analysis applied to essential tremor thalamotomy by focused ultrasound and gamma knife.
Schlesinger, D; Lee, M; Ter Haar, G; Sela, B; Eames, M; et al. (TAYLOR & FRANCIS LTD, 2017-01-31)Thermal dose and absorbed radiation dose have historically been difficult to compare because different biological mechanisms are at work. Thermal dose denatures proteins and the radiation dose causes DNA damage in order ... -
Feasibility of palliating recurrent gynecological tumors with MRGHIFU: comparison of symptom, quality-of-life, and imaging response in intra and extra-pelvic disease.
Imseeh, G; Giles, SL; Taylor, A; Brown, MRD; Rivens, I; et al. (TAYLOR & FRANCIS LTD, 2021-01-01)OBJECTIVE: To document longitudinal symptom, quality-of-life and imaging response in patients with recurrent gynecological tumors treated with magnetic resonance guided high intensity focused ultrasound (MRgHIFU), and ... -
Latest Advances in the Use of Therapeutic Focused Ultrasound in the Treatment of Pancreatic Cancer.
Mouratidis, PXE; Ter Haar, G (MDPI, 2022-01-27)Traditional oncological interventions have failed to improve survival for pancreatic cancer patients significantly. Novel treatment modalities able to release cancer-specific antigens, render immunologically "cold" pancreatic ... -
Maternal and fetal cardiometabolic recovery following ultrasound-guided high-intensity focused ultrasound placental vascular occlusion.
Shaw, CJ; Rivens, I; Civale, J; Botting, KJ; Allison, BJ; et al. (ROYAL SOC, 2019-05-31)High-intensity focused ultrasound (HIFU) is a non-invasive method of selective placental vascular occlusion, providing a potential therapy for conditions such as twin-twin transfusion syndrome. In order to translate this ... -
Pulsed focused ultrasound can improve the anti-cancer effects of immune checkpoint inhibitors in murine pancreatic cancer.
Mouratidis, PXE; Costa, M; Rivens, I; Repasky, EE; Ter Haar, G (ROYAL SOC, 2021-07-07)Pulsed high-intensity focused ultrasound (pHIFU) uses acoustic pressure to physically disrupt tumours. The aim of this study was to investigate whether pHIFU can be used in combination with immune checkpoint inhibitors ... -
Quantitative photoacoustic imaging study of tumours in vivo: Baseline variations in quantitative measurements.
Martinho Costa, M; Shah, A; Rivens, I; Box, C; O'Shea, T; et al. (ELSEVIER GMBH, 2019-03-01)Photoacoustic imaging (PAI) provides information on haemoglobin levels and blood oxygenation (sO2). To facilitate assessment of the variability in sO2 and haemoglobin in tumours, for example in response to therapies, the ... -
Response to comment by G. Borasi.

(SPRINGERNATURE, 2018-05-10)BACKGROUND: Magnetic resonance (MR)-guided high-intensity focused ultrasound (HIFU) can palliate metastatic bone pain by periosteal neurolysis. We investigated the value of diffusion-weighted imaging (DWI) for monitoring ...
