A prospective study involving 87 patients was carried out to evaluate the necessity for a high dose of contrast material in addition to delayed computed tomographic (CT) scanning for optimal detection of the lesions of multiple sclerosis in the brain. In patients with either clinically definite multiple sclerosis or laboratory-supported definite multiple sclerosis, CT scans were obtained with a...

Background LGE requires appropriate TI setting to null viable myocardium, which can be challenging and time consuming. Phase sensitive inversion recovery (PSIR) makes the TI choice less crucial for 2D imaging. However, for 3D PSIR navigator gating is required for both IR and reference data significantly increasing scan time. Additionally using a fixed single TI for a 3D scan while contrast wash...

The “Things We Do for No Reason” (TWDFNR) series reviews practices which have become common parts of hospital care but which may provide little value to our patients. Practices reviewed in the TWDFNR series do not represent “black and white” conclusions or clinical practice standards, but are meant as a starting place for research and active discussions among hospitalists and patients. We invit...

BACKGROUND Attempted nonsurgical reduction of ileocolic intussusceptions after 48 hours is controversial because of the low probability of reduction and an increased risk of perforation. We sought to retrospectively identify computed tomography (CT) criteria that may help to predict bowel viability and successful enema reduction in children with ileocolic intussusception. METHODS Unanticipate...

Objective: To determine common presenting symptoms, age, disease extent; and the efficacy of different surgical approaches in the diagnosis and treatment of Angiofibroma of nasopharynx. Design: All prepubertal and adolescent patients presenting with nasal obstruction, recurrent epistaxis, denasal speech, conductive deafness and anaemic look, reporting to our dept for consultancy were evaluated....

Parapelvic cysts are uncommon conditions that are usually found during autopsy. Their ultrasonographic appearance is similar to hydronephrosis. We report the case of a 46-year-old female with a 4-year history of vague flank pain and a previous history of bilateral moderate hydronephrosis. The patient was investigated by ultrasonography and non-enhanced CT scan, and finally diagnosed as bilatera...

Magnetic resonance imaging (MRI) is a powerful clinical imaging technique that allows for non-invasive tomographic visualization of anatomic structures with high spatial resolution and soft tissue contrast. However, its application in molecular imaging of cancer has been limited due to the lack of sensitivity and detection accuracy in identifying the biological processes of this disease. Recent...

introduction: contrast sensitivity is one of the most important psychophysical tests that may be used for the evaluation of refractive state of eye and retinal image quality. yellow vs. blue color contrast sensitivity may be more suitable in this regard. materials and methods: thirty myopic eyes were considered in this study. yellow vs. blue color contrast sensitivity was evaluated under the sa...
