Diagnostic peritoneal lavage (DPL) is a highly accurate test for evaluating intraperitoneal hemorrhage or a ruptured hollow viscus, but is performed less frequently today due to the increased use of focused abdominal sonography for trauma (FAST) and helical computed tomography (CT). All three of these exams have advantages and disadvantages and thus each still play unique roles in the evaluatio...

Computed tomography (CT) of the temporal bone is used routinely in otology clinics. The development of multi-slice helical CT (MSCT) has improved the quality of images of the temporal bone and enhanced diagnostic competence significantly . However, MSCT images of minute bony structures in the temporal bone are not always clear enough to allow an accurate diagnosis and images of metal implants a...

INTRODUCTION Radiotherapy is a standard treatment for prostate cancer, and image-guided radiotherapy is increasingly being used to aid precision of dose delivery to targeted tissues. However, precision during radiotherapy cannot be maintained when unexpected intrafraction organ motion occurs. CASE PRESENTATION We report our experience of internal organ motion caused by persistent gas producti...

We investigated the usefulness of helical computed tomography(CT)in the morphological diagnosis of pulmonary vein stenosis, particularly that in infants and small children. In total, 20 helical CT examinations were performed in 10 post-operative cases of Total Anomalous Pulmonary Venous Drainage(TAPVD), 3 cases of single right ventricle, and 1 case of single left ventricle. In all cases, distin...

Background: Computed tomographic (CT) colonography, also known as "virtual colonoscopy," is an imaging technique of the colon involving helical computed tomography and computer software to generate high-resolution 2-dimensional and 3-dimensional images of the inner surface of the colon. These images are then interpreted by a radiologist to determine the presence of several types of abnormalitie...
