Imaging is essential in successfully executing radiation therapy (RT) in oncology clinical trials. As technically sophisticated diagnostic imaging and RT were incorporated into trials, quality assurance in the National Clinical Trials Network groups entered a new era promoting image acquisition and review. Most trials involving RT require pre- and ...
The current practice of radiation oncology now requires a strong relationship with all radiology subspecialists and is embedded with a variety of imaging modalities and formats for both treatment planning and treatment execution. Unlike technology in the past, modern treatment technology delivery systems include kilovoltage imaging and cone beam co...

BackgroundRadiology is an important aspect of medicine to which medical students often do not receive sufficient exposure. The aim of this project was to determine whether the integration of an innovative e-learning module on chest x-ray interpretation of the heart would enhance the radiological interpretive skills, and improve the confidence, of f...
Behcet’s disease is inflammatory vasculitis that has a high incidence of mortality in patients with pulmonary artery aneurysm (PAA) formation. Traditionally, patients with Behcet’s disease and PAA rupture undergo invasive surgical management. Surgical intervention; however, has been shown to have high complication, failure, and mortality rates. It ...
PURPOSE: Single-photon emission computed tomography (SPECT) is a noninvasive imaging modality, used in myocardial perfusion imaging. The challenges facing the majority of clinical SPECT systems are low sensitivity, poor resolution, and the relatively high radiation dose to the patient. New generation systems (GE Discovery, DSPECT) dedicated to card...
BACKGROUND: We previously optimized several reconstruction strategies in SPECT myocardial perfusion imaging (MPI) with low dose for perfusion-defect detection. Here we investigate whether reducing the administered activity can also maintain the diagnostic accuracy in evaluating cardiac function. METHODS: We quantified the myocardial motion in cardi...

A 35-year-old lactating woman with pre-existing polyacrylamide gel (PAAG) implants for 10 years presented on numerous occasions following both her pregnancies with bilateral recurrent breast infection, pain and finally massive breast enlargement with a ruptured galactocoele necessitating surgical intervention. As the safety of PAAG for the breastfe...

ObjectiveSignificant geographical variations in the use of diagnostic imaging have been demonstrated in Norway and elsewhere. Non-traumatic musculoskeletal conditions is one area where this has been demonstrated. A national musculoskeletal guideline was implemented in response by online publishing and postal dissemination in Norway in 2014 by natio...
Endovascular aortobifemoral bypass repair with aortic bifurcation reconstruction is a well-established option with mortality benefits compared to conventional surgical management. The same theory, formulas, and techniques can be applied to the central venous system as long as there are commercially available devices. Using mathematically derived cr...
Mesenteric ischemia is an uncommon condition resulting from decreased blood flow to the small or large bowel in an acute or chronic setting. Acute ischemia is associated with high rates of morbidity and mortality; however, it is difficult to diagnose clinically. Therefore, a high degree of suspicion and prompt imaging evaluation are necessary. Chro...
