[ 1 ] - Ultrasonographic Evaluation of the Sacrococcyx and Spinal Canal in Children with Constipation
Background The occult neurological disorders are an important cause of constipation in children. This study aimed to evaluate the spinal canal and lumbosacral by ultrasound in pediatric constipation to better identifying neurological causes of constipation. Materials and Methods In this case-control study, 100 children with constipation (age range 1 to 14 years) without previously known chronic...
[ 2 ] - Assessment of Diagnostic Value of Single View Dynamic Technique in Diagnosis of Developmental Dysplasia of Hip: A Comparison with Static and Dynamic Ultrasond Techniques
Background: Developmental dysplasia of hip (DDH) is a common childhood disorder, and ultrasonography examination is routinely used for screening purposes. In this study, we aimed to evaluate a modified combined static and dynamic ultrasound technique for the detection of DDH and to compare with the results of static and dynamic ultrasound techniques. Methods:In this cross-sectional study...
[ 3 ] - New Method of Quality Control Test for Light and Radiation Field Coincidence in Medical Linear Accelerators
Introduction: The evaluation of X-ray and light field coincidence in linear accelerators as a quality control test is often performed subjectively, involving the manual marking of films and their visual inspection following the irradiation. Therefore, the present study aimed to develop an objective method for the performance of this test leading to the increased levels...
[ 4 ] - New electrical device for field coincidence quality control test in linear accelerators
Testing of the coincidence of a linear accelerators X-ray field and the light field as a quality control test is often done in a subjective method, involving the manual marking of pieces of film and the visual inspection of the film after irradiation. The purpose of this study was to develop an objective method for performing this test, while also increasing the accuracy, precision and the spee...
[ 5 ] - Specific Ultrasound Pattern of Perinatal Torsioned Ovarian Cysts: Sonographic-pathologic Correlation
Background: The accurate differentiation of perinatal torsioned ovarian cysts (PTOCs) in neonates is of utmost importance. This importance is due to the fact that if PTOCs are diagnosed properly, minimally invasive or conservative management approaches can be offered. The present study aimed to describe the ultrasound findings of PTOCs and compare the results with pathological findings.Me...
