BACKGROUND AND PURPOSE Contrast-enhanced spiral CT studies of the head and neck are performed frequently using contrast material volumes of approximately 30 g iodine and a scan delay of 30-45 seconds. Because little is known about the effects of contrast material injection rates on tissue enhancement, this was prospectively investigated in our study. (More)
BACKGROUND Patients with breast carcinomas 1 cm or smaller are known to have the highest long term survival rates. This pathologic measurement was used as a quality indicator of the performance of different reporting radiologists. METHODS A total of 26,711 diagnostic breast imaging studies were performed over a period of 5 years. Within the first 18(More)
We investigated a method for a fully automatic identification and interpretation process for clustered microcalcifications in mammograms. Mammographic films of 100 patients containing microcalcifications with known histology were digitized and preprocessed using standard techniques. Microcalcifications detected by an artificial neural network (ANN) were(More)
Teaching the skills needed to animate in current 3D software is difficult. Learning it may be more so. Being the only totally digital art form, it does not fall neatly into computer science or art. It does share an abundance of the complexities and consternations of both. Current applications can feel like a hodge-podge of ideas from drafting, particle and(More)
Neuromyelitis optica (NMO, also known as Devic syndrome or Devic disease) is a rare clinical entity. Early recognition and prompt treatment can save patients from long-term disability, especially in themonophasic variant of disease. A 24-year-old African American female presented with high-grade fever for 1 day associated with frontal headache, photophobia,(More)
Today mammography represents the only imaging modality that decreases with the help of screening programs the mortality rate of breast cancer patients. This becomes increasingly necessary because already every tenth woman in Austria will get this tumor during her lifetime. There is conclusive evidence that the patients chance for survival depends on the(More)
