Cranial computed tomography has been performed in adults for the past 2 years but relatively few children have undergone this procedure. The specific uses in children are in detecting intracranial mass lesions and identifying the character of the lesion, and evaluating congenital cranial diseases such as cerebral dysplasia, tuberous sclerosis and leukodystrophies. This safe, rapid, noninvasive ...

Two hundred seventy-five cranial computed tomography (CT) scans performed on 179 patients with malignant melanoma were reviewed. Of the 101 patients with confirmed cerebral metastases, CT demonstrated lesions in 93. In 72% of these, areas of increased attenuation were present in the precontrast scan. These lesions also enhanced after contrast infusion. There was a direct correlation between the...

Computed tomographic (CT) scann ing is very accurate in the recog nition of intracerebral hemorrhage. However, when radiographic contrast material has been administered, there may be confus ion between an unsuspected hematoma and an enhancing brain lesion . We recently encountered two cases of spontaneous hemorrhage occurring during the enhancement phase of the CT examination immediately after ...

Recent software additions to a CT scanner with a continuously rotating tube-detector system allow uninterrupted data collection after rapid intravenous contrast material injection. The highly flexible computer program can accommodate as many as 16 consecutive 3 sec scans, or various time intervals can be inserted between individual scans. A variety of intracranial lesions was studied in 35 pati...

OBJECTIVE Head injury in children is a common problem presenting to emergency departments, and cranial computed tomography scanning is the diagnostic standard for these patients. Several decision rules are used to determine whether computed tomography scans should be used; however, the use of computed tomography scans is often influenced by guardians' preference toward the scans. The objective ...

neurolymphomatosis is a rare manifestation of non-hodgkin lymphoma characterized by infiltration of peripheral nerves, nerve roots, plexus and cranial nerves by malignant lymphocytes. this report presents positron emission tomography/computed tomography (pet/ct)imaging with 2-deoxy-2-18f-fluoro-d-glucose (18f-fdg) in 3 cases of non-hodgkin lymphoma with nerve infiltration, including one newly d...

isolated third nerve palsy develops in numerous intracranial pathologies such as closed head trauma, tumor, and aneurysm. this report describes a 61 years old female with an abrasion on the left forehead and ptosis of the left eye. initial computed tomography did not reveal any causative cerebral and vascular lesions or orbital and cranial fractures. high-resolution and multi-axial enhanced mag...

Of 564 consecutive patients with transient ischemic attack, 350 (62%) had cranial computed tomography performed. Except for date of admission and smoking history, there were few differences between the patients evaluated with computed tomography and the 214 who were not. Cerebral infarcts were found in 59 (17%) of the 350 tomographic evaluations. Previous clinically diagnosed stroke, older age,...

OBJECTIVES A recent American study identified clinical factors which effectively predicted those patients who would have significant findings on cranial computed tomography. It was proposed to apply these criteria in a UK setting and to determine whether modifications could be made to improve their efficiency. METHODS A prospective observational study was conducted over a four month period in...
