BACKGROUND The National Lung Screening Trial showed a reduction in overall and cancer-specific mortality for patients screened with low-dose computed tomography (LDCT) versus chest radiograph. Some question whether this can be achieved in community healthcare settings. Our aim was to analyze lung cancer screening outcomes and administered radiation dose(More)
PURPOSE To determine the dose-length product (DLP)-effective dose (ED) (DLP/ED) conversion coefficient (k) tables for the lower extremities that can be used for calculating ED. MATERIALS AND METHODS Dose calculations were performed on standard phantoms using a validated Monte Carlo calculation tool. Calculations were performed to obtain ED values for tube(More)
BACKGROUND Computed tomography (CT) plays an integral role in the evaluation and management of trauma patients. As the number of referring hospital (RH)-based CT scanners increased, so has their utilization in trauma patients before transfer. We hypothesized that this has resulted in increased time at RH, image duplication, and radiation dose. METHODS A(More)
In November 2007, the Wisconsin Division of Public Health Hospital Disaster Preparedness Program State Expert Panel on Radiation Emergencies issued a report titled The Management of Patients in a Radiological Incident. Gundersen Lutheran Health System was selected to conduct a demonstration project to implement the recommendations in that report. A(More)
I was born in Beaver Dam, Wisconsin, and grew up on a farm north of Madison, Wisconsin (see a portrait of Ms. Jafari in Fig. 1). I earned a Bachelor of Science degree in physics and a Master of Science degree in medical physics, both from the University of Wisconsin-Madison. In 1992, I was certified by the American Board of Radiology in medical nuclear(More)
Although computed tomography (CT) scan radiation dose has drawn much attention, radiation dose from nuclear medicine procedures should not be overlooked. An estimated 19.7 million nuclear medicine procedures are done annually in the United States, with patient radiation dose comparable to that from CT scans. Nuclear medicine departments should implement(More)
