introduction: in cases of blunt abdominal traumas, predicting the possible intra-abdominal injuries is still a challenge for the physicians involved with these patients. therefore, this study was designed, to evaluate the accuracy of urinalysis in predicting intra-abdominal injuries. methods: patients aged 15 to 65 years with blunt abdominal trauma who were admitted to emergency departments wer...
Objective: A commercially available dual energy X-ray absorptiometry scanner normally provides more than 1 scan mode. The differences between scan modes affect scan time, received radiation dose, and quality of the scan image. A phantom study was performed to evaluate the performance of different scan modes for anteriorposterior spine scan. Patients and Methods: To measure the entrance skin exp...
ct image quality has been affected by many factors such as kvp, ma, exposure time, alogorithm and section thickness. gantry tilt has the main role in visualization of the temporal bone anatomic structures. in this study, we tried to optimize these factors to determine the best gantry tilt. this study was performed on the human skull phantom and then extended to 15 patients. the phantom was made...
BACKGROUND AND PURPOSE CTP imaging in the interventional suite could reduce delays to the start of image-guided interventions and help determine the treatment progress and end point. However, C-arms rotate slower than clinical CT scanners, making CTP challenging. We developed a cerebral CTP protocol for C-arm CBCT and evaluated it in an animal study. MATERIALS AND METHODS Five anesthetized sw...
