A new approach to contrast enhancement in MAGICA gel dosimeter image with MRI technique
parameters that have to be measured in gel dosimetry. However, the resolution in gel is strongly dependant on gel composition. Selection of optimum method in dose response readout and proper values of parameters can result in noise reduction as well as improvement of contrast, and spatial resolution considerably. Materials and Methods: MAGICA polymer gel dosimeters were manufactured and irradia...
متن کاملElimination of non-ionic contrast medium by hemodialysis in patients with impaired renal function.
The elimination rate of iohexol, a non-ionic contrast medium, from the blood by hemodialysis, and the elimination rate of iohexol by a dialyzer were studied in 15 patients with chronic renal dysfunction who required angiography or enhanced CT. The elimination rate of iohexol was 19.8% at 15 min after the start of hemodialysis, 30.6% after 30 min, 44.2% after 1 hour, 62.1% after 2 hours and 72.9...
متن کاملDeveloping a PC-based portal image contrast enhancement program
ABSTRACTBackground: Delivering the radiation dose to the target volume and minimizing the dose to normal tissues are the main objectives in radiotherapy. The aim of our study is to enhance the contrast of the portal image to increase the accuracy of delineation of the organs in the irradiation field. Methods: The software was written based on local enhancement of the pixel values in image ma...
متن کاملContrast Induced Nephropathy After Brain and Cervical CT Angiography in Stroke Patients: A Prospective Study
Background: Contrast-induced nephropathy (CIN) is a major side effect of intravenous iodinated contrast and causes both short- and long-term adverse effects. While diagnostic and interventional procedures of brain ischemia are recently advanced, it is necessary to be cautious about its major side effect. Objectives: To evaluate CIN and its risk factors in neurology patients after brain and cer...
متن کاملContrast Enhancement of Mammograms for Rapid Detection of Microcalcification Clusters
Introduction Breast cancer is one of the most common types of cancer among women. Early detection of breast cancer is the key to reducing the associated mortality rate. The presence of microcalcifications clusters (MCCs) is one of the earliest signs of breast cancer. Due to poor imaging contrast of mammograms and noise contamination, radiologists may overlook some diagnostic signs, specially t...
