A comparative evaluation of rare earth screen-film systems. Free-response operating characteristic analysis and anatomic criteria analysis.

Diagnostic accuracy was evaluated in a signal detection experiment that used low-contrast acute lesions in a living dog model. At the high levels of certainty normally used by radiologists, rare earth screen-film systems provided accuracy comparable to that of a reference calcium tungstate screen-film system. Additionally subjective image quality evaluation for a given imaging task (clinical pediatric anterior-posterior chest films) based on visualization of anatomic landmarks and physical parameters has been conducted for several rare earth and one calcium tungstate screen-film system. The correspondence of subjective physical ranking with physical and psychophysical measurements was investigated. Evaluating the visualization of anatomic parameters can provide a clear and objective distinction among systems with comparable physical and psychophysical properties.

Computed tomography in the evaluation and management of patients with spina bifida.

Computed tomography (CT) has fundamentally altered our approach to the initial evaluation and follow-up of patients with spina bifida. This safe and simple, non-invasive diagnostic technique has doubtlessly encouraged earlier diagnosis of clinically significant problems associated with spina bifida and has greatly facilitated the day-to-day management of those patients with documented disorders. CT is now effectively employed as a screening measure for both intraspinal and intracranial problems and can be relied upon to objectively guide and monitor elected modes of therapy.

Computerized tomography in the evaluation of isosexual precocity.

Clinical and laboratory observations were made in three children with isosexual precocity. None of the patients showed abnormalities in neurological or visual-field examinations although one patient had arrested hydrocephalus and a head circumference greater than the 98th percentile for her age and another patient had a history of seizures. Roentgenograms of the skull were normal in all patients. Cranial computerized tomography (CT) identified a lesion in each patient. We believe that craniel CT should be performed in any patient with isosexual precocity in whom a specific cause is not evident or in whom a cerebral cause is suggested even though the patient may be otherwise normal. Cranial CT is a safe, accurate, and noninvasive technique.
