CT imaging doses in radiotherapy-a single centre audit
: Purpose or Objective: There is a growing awareness of dose delivered to parts the body outside the target volume during external beam radiotherapy. This concomitant dose could arise from external linac head leakage and ...
Modelling the radiobiological effect of intraoperative X-ray brachytherapy for breast cancer using an air-filled spherical applicator.
PURPOSE: We present a framework, in which we compare a conventional standard dose of 50 Gy in 25 fractions with accelerated partial breast irradiation (APBI) using electronic brachytherapy (eBT). We discuss how radiobiological ...
The accuracy of breast volume measurement methods: A systematic review.
Breast volume is a key metric in breast surgery and there are a number of different methods which measure it. However, a lack of knowledge regarding a method's accuracy and comparability has made it difficult to establish ...
Accuracy of GE digital breast tomosynthesis vs supplementary mammographic views for diagnosis of screen-detected soft-tissue breast lesions.
OBJECTIVE: To compare the accuracy of standard supplementary views and GE digital breast tomosynthesis (DBT) for assessment of soft-tissue mammographic abnormalities. METHODS: Women recalled for further assessment of ...
Factors influencing local control in patients undergoing breast conservation surgery for ductal carcinoma in situ.
BACKGROUND: The aim of our study was to assess various predictors for local recurrence (LR) in patients undergoing breast conservation surgery (BCS) for ductal carcinoma in situ (DCIS). MATERIALS AND METHODS: An audit was ...
Non-invasive assessment of Portal Hypertension Using Quantitative Magnetic Resonance Imaging.
BACKGROUND & AIMS: Hepatic venous pressure gradient (HVPG) measurement is currently the only validated technique to accurately evaluate changes in portal pressure. In this study, we evaluate the use of non-contrast ...
Do we need to follow up an early normal ultrasound with a later plain radiograph in children with a family history of developmental dysplasia of the hip?
BACKGROUND: We routinely perform a pelvic radiograph between 6 and 12 months of age for children with a family history of developmental dysplasia of hip (DDH). We conducted this study to determine whether children with a ...
Quality assurance and its impact on ovarian visualization rates in the multicenter United Kingdom Collaborative Trial of Ovarian Cancer Screening (UKCTOCS).
OBJECTIVE: To describe the quality assurance (QA) processes and their impact on visualization of postmenopausal ovaries in the ultrasound arm of a multicentre screening trial for ovarian cancer. METHODS: In the United ...
