Giant cell arteritis often affects extra-cranial vessels and may not present as a classical cranial arteritis. It must be considered in patients over 50 with constitutional symptoms and raised inflammatory markers. Initial investigations are usually non-specific, but positron emission tomography–computed tomography is normally diagnostic. Prompt treatment with corticosteroids is required for th...

conclusions the automatic bolus-tracking method, results in higher contrast enhancement of the aorta and spleen at the portal phase, but has no effect on liver enhancement. however, bolus tracking is associated with reduced variability for liver enhancement among different patients. results forty-eight patients (23 male, 25 female, mean age=56.4±13.5 years) were included. the contrast enhanceme...

In 29 children with mental retardation and infantile spasms, cranial computed tomography findings were abnormal in 75% and this finding may lead to modification of treatment or influence genetic counseling. In 41 children with mental retardation and other forms of epilepsy abnormal computed tomography findings were much less frequent and were not relevant to treatment.

In three patients with histologically confirmed, acute demyelinating disease (multiple sclerosis), serial cranial computed tomography revealed unusual findings. Computed tomography showed contrast-enhancing lesions with mass effect, which suggested brain tumors and the need for surgical biopsy. Steroids were administered to each patients; in two, the large mass lesions resolved dramatically. Th...

Background: One of the means of assessing dose to patients from Computed tomography (CT) procedure is through the determination of the skin entrance dose (ESD) with the appreciation of the concern that ocular exposure effects from CT scan includes possible induction of cancer and cataract. Due to the relatively more recent introduction of CT scans, little work has been done in this area in the ...
