Results of a National Study Examining the Prevalence and Potential for Developing Compassion Fatigue and Burnout in Radiation Therapists
Caring is a fundamental tenet of healthcare. Caring “too much” can result in compassion fatigue syndrome (CFS) and is often linked to burnout and low morale. Anecdotal reports from Radiation Therapists (RTTs) demonstrate empathy towards patients and sometimes RTTs have difficulty coping with these emotions. Our study examines the empathic sensitivity of RTTs in their therapeutic relationships to examine the prevalence and potential for developing CFS and burnout.

What Do You Hope For? The Role of Hope in Palliative Cancer Patients
Palliative care and hope have both been known to improve the quality of life (QoL) in palliative cancer patients. Hope is a complex, multidimensional concept that is influenced by a variety of factors and is considered to be an effective coping strategy when dealing with serious illness.

The Grey Area: Defining Scope of Practice for Nurses and Radiation Therapists within the Radiation Oncology Program Focusing on Role Clarity; Enhanced Communication and Improved Collaboration
Interprofessional care is the provision of comprehensive health services to patients by multiple health caregivers who work collaboratively to deliver quality care within and across settings. However, differing philosophical and theoretical backgrounds, lack of understanding of professional roles and responsibilities, and role blurring can lead to interprofessional tension, protection of scope of practice, underutilization of professional expertise, and decreased satisfaction. At the Odette Cancer Centre (OCC), Radiation Therapists (RT) and Nurses (RN) provide care to patients who are receiving radiation therapy along a co...

Time for An Upgrade: Should the Treatment Process Evolve as Technology Grows?
The Odette Cancer Centre (OCC) is currently undergoing a treatment delivery quality improvement project to review radiation treatment delivery that occurs on a daily basis within the department. Treatment delivery has become increasingly complex with the introduction of IMRT, IGRT, SBRT and VMAT and the work performed by the Radiation Therapists (RT) has been radically transformed. However, department structure, scheduling (both staff and patient) and workflow have remained largely unchanged for forty years. Through a structured and formalized process review, the project team would like to investigate if there are any pote...

Dosimetric Benefits of Patient-Specific Planning Target Volume Margins for Bladder Cancer Radiotherapy
Precision during bladder cancer radiotherapy delivery is particularly challenging due to large daily variations in bladder position and volume, despite attempts to control for this during simulation and treatment. The literature suggests that the optimal approach to margin calculation is a patient specific one, because the magnitude and direction of bladder changes varies significantly between patients. By employing patient-specific techniques, planning target volume (PTV) margins sizes can be greatly reduced as compared to standard population-based (popPTV) margins. However, there is little information about whether this ...

Randomized Intra-Patient Controlled Trial of Mepilexlite Dressings vs. Aqueous Cream in Managing Radiation-Induced Skin Reactions Post-Mastectomy
Severe acute radiation-induced skin reactions occur in a significant proportion of women who receive radiation therapy for breast cancer.

Development and Implementation of an Electronic Education Tool for Volumetric Image Guided Radiation Therapy
Image-guided radiation therapy (IGRT) through daily cone-beam computed tomography (CBCT) has significantly impacted the role of the Radiation Therapist at our institution; continuing education is crucial to ensure safe practice of technology in the clinical environment. The purpose of this work was to develop an electronic refresher module for CBCT-practicing Radiation Therapists, with an aim to equip staff with the critical thinking skills and clinical judgment required to operate in a CBCT-IGRT environment.

Communicating with Emotional Patients: Thoughts, Skills and Influencing Factors for Ontario Radiation Therapists
Patients receiving radiation therapy are subject to very high anxiety levels. Therapists are uniquely positioned to support patients as they progress through treatment, but little is known about therapists’ ability to perform this important task. Therefore, this research was designed to describe radiation therapists’ ability to communicate with cancer patients during emotional interactions and to determine what intrinsic and extrinsic factors influence that ability.

4D Dark Blood Arterial Wall Magnetic Resonance Imaging: Methodology and Demonstration in the Carotid Arteries.
CONCLUSION: 4D blood suppressed MRI of the human vascular system with submillimeter isotropic spatial resolution is feasible in a clinically reasonable scan time, and data obtained in the carotid arteries show good agreement with established MRI techniques. Future efforts will examine the constellation of data provided by the method and investigate its utility for assessing cardiovascular risk. Magn Reson Med, 2013. © 2013 Wiley Periodicals, Inc.

Imaging of Endogenous Exchangeable Proton Signals in the Human Brain Using Frequency Labeled Exchange Transfer Imaging.
CONCLUSIONS: FLEX MRI in the human brain preferentially detects more rapidly exchanging amide/amine protons compared to traditional CEST experiments, thereby changing the information content of the exchangeable proton spectrum. This has the potential to open up different types of endogenous applications as well as more easy detection of rapidly exchanging protons in diaCEST agents or fast exchanging units such as water molecules in paracest agents without interference of conventional magnetization transfer contrast.

Improved slice-selective adiabatic excitation.
CONCLUSIONS: STABLE-2 achieves B(1) -insensitive slice-selective excitation while providing greater off-resonance immunity and a shorter pulse duration, when compared to the original STABLE pulse. In particular, the 9.8-ms STABLE-2 pulse provides slice selectivity over 120 Hz whereas the 21-ms STABLE pulse is limited to 80 Hz off-resonance. B(1) -Insensitive fat-suppressed excitation may also be achieved by using a variant of this pulse. Magn Reson Med, 2013. © 2013 Wiley Periodicals, Inc.

Electrical Properties Tomography in the Human Brain at 1.5, 3, and 7T: A Comparison Study.
CONCLUSION: The transceive phase assumption is most accurate for low-field strengths and low permittivity and in symmetric objects. The phase-only conductivity reconstruction is only applicable at 1.5 and 3T for the investigated geometries. The measurement precision was found to benefit from a higher field strength, which is related to increased signal-to-noise ratio (SNR) and increased curvature of the B(1) (+) field.

Characterization of a chip-based bioreactor for three-dimensional cell cultivation via magnetic resonance imaging.
We describe the characterization of a chip-based platform (3(D)-KITChip) for the three-dimensional cultivation of cells under perfusion conditions via magnetic resonance imaging (MRI). Besides the chip, the microfluidic system is comprised of a bioreactor housing, a medium supply, a pump for generating active flow conditions as well as a gas mixing station. The closed circulation loop is ideally suited for a characterization via MRI since the small bioreactor setup with active perfusion, driven by the pump from outside the coils, not only is completely MRI-compatible but also can be transferred into the magnetic coil of an...

Perfusion MRI at rest in subacute and chronic myocardial infarct.
ConclusionPerfusion is decreased in subacute reperfused infarct tissue compared to normal tissue. K(trans) is not decreased, consistent with increased surface area of the vascular bed of the subacute infarct. Infarct tissue v(e) is increased, and decreases with scarring. The presence of persistent MO correlates to more pronounced perfusion reduction and results in delayed contrast arrival, indicating microvascular collateral circulation.

A dual‐tuned transceive resonator for 13C{1H} MRS: two open coils in one
Proton‐decoupled, 13C nuclear MRS experiments require a RF coil that operates at the Larmor frequencies of both 13C and 1H. In this work, we designed, built and tested a single‐unit, dual‐tuned coil based on a half‐birdcage open coil design. It was constructed as a low‐pass network with a resonant trap in series with each leg. Traps are tuned in alternate legs such that the two resonant modes arise from currents on alternate legs. The coil performance was compared with that of a dual‐tuned coil consisting of two proton surface coils operating in quadrature and a single surface coil for 13C transmission and rece...
