For years, equine surgeons have found equine skull radiography to be a valuable tool in the diagnosis and management of dental disease. The excellent contrast between air, bone, soft tissue, and tooth substance make the head an ideal area for radiographic evaluation. Conventional or standard radiographic projections adequately image the reserve crown apices, lamina dura denta, alveolar space, a...

Background Gastrointestinal (GI) obstruction is one of the most important surgical emergencies in neonates. Surgeons should select between conservative and invasive strategies. Imaging modalities are important in proper diagnosis. This study evaluates the sensitivity of abdominal radiographies (with or without contrast) in detection of neonatal GI obstruction. Materials and Methods A cross-sect...

objectives : optimum viewing conditions facilitate identification of radiographic details and decrease the need for retakes, patients’ costs and radiation dose. this study sought to evaluate the effects of different viewing conditions on radiographic interpretation. materials and methods: this diagnostic study was performed by evaluating radiograph of a 7mm-thick aluminum block, in which 10 hol...

abstract background: the radiographic image accuracy depends on the x-ray film information visibility. good visibility is found by good contrast. radiation exposure parameters (kvp, mas) and film processing conditions have impact on contrast. in dentistry radiography machines, exposure time and processing procedure are set by radiographer. no optimized exposure time and processing conditions ma...

During the last two decades the development of contrast agents for myelography, angiography, computed tomography (CT) and magnetic resonance imaging (MR) has been remarkable. What follows is a review of contrast agents used in neuroradiology-specifically, the ionic and nonionic contrast agents for radiographic/CT procedures, and the paramagnetic contrast agents used in MR studies. Topics covere...

Objectives: The author demonstrates a variation of the transforaminal injection technique. The radiographic spread of contrast is described using a more oblique and ventral caudad approach in the epidural space “retrodiscal.” It is suggested that the radiographic findings of this technique for discogenic causes of induced radiculitis and/or back pain may yield more precise targeting of putative...

PURPOSE To study the role of Gd-DTPA in cranial MR of patients with Sturge-Weber syndrome. METHODS AND MATERIALS Seven patients with Sturge-Weber syndrome, ages 3 months to 36 years, were evaluated with unenhanced and contrast-enhanced (Gd-DTPA) MR imaging. Correlation was made to cranial CT in five patients. RESULTS MR findings included (in decreasing frequency): pial angiomatosis, cerebra...

In the 1930s and 1940s the radioactive contrast material colloidal thorium dioxide (Thorotrast) was frequently used in radiographic examinations. The agent was used mainly for angiography and to a lesser extent for myelography, ventriculography, pyelography, and hepatolienography. The late clinical complications and conventional radiographic manifestations of thorium administration have been we...

conclusion dt-sfp can improve the detection of relatively early bone abnormalities in acetabular and proximal femur compared with conventional radiography. dt-sfp can also observe the abnormal impact between acetabular and proximal femur. patients and methods ninety-four consecutive patients with discomfort around the hip joint underwent dt-sfp and conventional radiography. the imaging features...
