UK Consensus on Normal Tissue Dose Constraints for Stereotactic Radiotherapy.
(2018-01)Six UK studies investigating stereotactic ablative radiotherapy (SABR) are currently open. Many of these involve the treatment of oligometastatic disease at different locations in the body. Members of all the trial management ... -
UKCGG Consensus Group guidelines for the management of patients with constitutional TP53 pathogenic variants.
(BMJ PUBLISHING GROUP, 2020-06-22)Constitutional pathogenic variants in TP53 are associated with Li-Fraumeni syndrome or the more recently described heritable TP53-related cancer syndrome and are associated with increased lifetime risks of a wide spectrum ... -
Ultrahigh Dose-rate Radiotherapy: Next Steps for FLASH-RT.
(2019-01)A new way of delivering radiotherapy at very high dose rates is described and compared with conventional radiotherapy. The ultrahigh dose-rate therapy reduces damage to normal pig skin and exerts potent activity against ... -
Ultrasonic Sound Speed Estimation for Liver Fat Quantification: A Review by the AIUM-RSNA QIBA Pulse-Echo Quantitative Ultrasound Initiative.
(ELSEVIER SCIENCE INC, 2023-08-05)Non-alcoholic fatty liver disease (NAFLD) is a significant cause of diffuse liver disease, morbidity and mortality worldwide. Early and accurate diagnosis of NALFD is critical to identify patients at risk of disease ... -
Ultrasound Measurement of Local Deformation in the Human Free Achilles Tendon Produced by Dynamic Muscle-Induced Loading: A Systematic Review.
(ELSEVIER SCIENCE INC, 2023-07-01)Achilles tendinopathy is the most prevalent lower limb tendinopathy, yet it remains poorly understood, with mismatches between observed structure and reported function. Recent studies have hypothesised that Achilles tendon ... -
Ultrasound Tomography Evaluation of Breast Density: A Comparison With Noncontrast Magnetic Resonance Imaging.
(LIPPINCOTT WILLIAMS & WILKINS, 2017-06-01)OBJECTIVES: Ultrasound tomography (UST) is an emerging whole-breast 3-dimensional imaging technique that obtains quantitative tomograms of speed of sound of the entire breast. The imaged parameter is the speed of sound ... -
Ultrasound-guided High Intensity Focused Ultrasound (HIFU) ablation of placental vasculature
(WILEY-BLACKWELL, 2015-04-01) -
Uncertainty analysis of tumour absorbed dose calculations in molecular radiotherapy.
(SPRINGER, 2020-10-12)BACKGROUND: Internal dosimetry evaluation consists of a multi-step process ranging from imaging acquisition to absorbed dose calculations. Assessment of uncertainty is complicated and, for that reason, it is commonly ignored ... -
Understanding the Benefit of Magnetic Resonance-guided Adaptive Radiotherapy in Rectal Cancer Patients: a Single-centre Study.
(ELSEVIER SCIENCE LONDON, 2022-11-03)AIMS: Neoadjuvant chemoradiotherapy followed by surgery is the mainstay of treatment for patients with rectal cancer. Standard clinical target volume (CTV) to planning target volume (PTV) margins of 10 mm are used to ... -
Updates in Prostate Cancer Research and Screening in Men at Genetically Higher Risk.
(SPRINGERNATURE, 2021-01-01)PURPOSE OF REVIEW: Prostate cancer (PrCa) is the most common cancer in men in the western world and is a major source of morbidity and mortality. Currently, general population PrCa screening is not recommended due to the ... -
Upfront Docetaxel in the Post-STAMPEDE World: Lessons from an Early Evaluation of Non-trial Usage in Hormone-Sensitive Prostate Cancer.

US Backscatter for Liver Fat Quantification: An AIUM-RSNA QIBA Pulse-Echo Quantitative Ultrasound Initiative.
(RADIOLOGICAL SOC NORTH AMERICA (RSNA), 2022-12-01)Nonalcoholic fatty liver disease (NAFLD) is believed to affect one-third of American adults. Noninvasive methods that enable detection and monitoring of NAFLD have the potential for great public health benefits. Because ... -
Use of a Novel Nonparametric Version of DEPTH to Identify Genomic Regions Associated with Prostate Cancer Risk.
(AMER ASSOC CANCER RESEARCH, 2016-12-01)BACKGROUND: We have developed a genome-wide association study analysis method called DEPTH (DEPendency of association on the number of Top Hits) to identify genomic regions potentially associated with disease by considering ... -
Use of Medications for Treating Anxiety or Depression among Testicular Cancer Survivors: A Multi-Institutional Study.
(AMER ASSOC CANCER RESEARCH, 2021-06-01)BACKGROUND: This study examined sociodemographic factors, cisplatin-related adverse health outcomes (AHO), and cumulative burden of morbidity (CBMPt) scores associated with medication use for anxiety and/or depression in ... -
Using dual-energy x-ray imaging to enhance automated lung tumor tracking during real-time adaptive radiotherapy.
(WILEY, 2015-12-01)PURPOSE: Real-time, markerless localization of lung tumors with kV imaging is often inhibited by ribs obscuring the tumor and poor soft-tissue contrast. This study investigates the use of dual-energy imaging, which can ... -
Uterine Cancer After Risk-Reducing Salpingo-oophorectomy Without Hysterectomy in Women With BRCA Mutations.
(AMER MEDICAL ASSOC, 2016-11-01)IMPORTANCE: The link between BRCA mutations and uterine cancer is unclear. Therefore, although risk-reducing salpingo-oophorectomy (RRSO) is standard treatment among women with BRCA mutations (BRCA+ women), the role of ... -
