Assessment of aggressiveness of prostate cancer: correlation of apparent diffusion coefficient with histologic grade after radical prostatectomy.
TLDR
The results show that ADC values might help to predict prostate cancer, especially for tumors in the peripheral zone, as well as the addition of other MR parameters, such as volumetry, and technical improvements in diffusion-weighted imaging might improve accuracy in the stratification of patients.
An improved methodology for modeling neurobehavioral late‐effects of radiotherapy in pediatric brain tumors
Technical advances in radiation oncology provide new opportunities to study neurobehavioral outcomes of radiation therapy (RT) in children treated for brain tumors.
Measurement of low‐energy backscatter factors using GAFCHROMIC film and OSLDs
TLDR
The scope of this project included making three different backscatter measurements with an Xstrahl‐D3100 X‐ray unit on the Grenz ray and superficial settings, with various measurement methods including OSLDs, GAFCHROMIC EBT2 film, and a PTW ionization chamber.
Measuring the photon depth dose distribution produced by a medical linear accelerator in a water-equivalent radio-fluorogenic gel
TLDR
Results support continued development of radio-fluorogenic gel dosimetry systems for quality assurance of clinical photon beams and show agreement was within 3 % of published values in most areas of electronic equilibrium.
Respiratory motion effects on whole breast helical tomotherapy.
TLDR
This phantom-based study specifically addressed the effects of intrafraction respiratory motion on whole breast helical tomotherapy with results representative of extreme deviations between planned and delivered dose with respect to sinusoidal motion of clinically relevant magnitudes and frequencies.
Axillary lymph node coverage of tangent radiotherapy: Comparison of supine versus prone positioning.
TLDR
Delivery of radiotherapy using simple tangent fields inadequately covers all axillary nodal levels and coverage is greater in the supine position with very little inadvertent coverage in the prone position.
Radio-Fluorogenic Gel Dosimetry with Coumarin
TLDR
Increased photo-yield with high pH and the utility of gelatin-RFG for phantom studies of radiation dosimetry are demonstrated and a linear dose response relationship independent of energy and type, with a dose-rate dependency is shared.
The volume of PET-defined, active bone marrow spared predicts acute hematologic toxicities in anal cancer patients receiving concurrent chemoradiotherapy
In 2016, anal cancer (AC) incidence was estimated to be 8080 which represented 0.5% of all cancer cases [1]. Despite advancing technology, the overall treatment paradigm has not changed since Nigro...
