Computerized axial tomography in clinical pediatrics.

Computerized axial tomography (CAT), a noninvasive radiologie method, provides a new dimension in screening and diagnosis of intracranial pathology. Evaluation of 725 scans in infants and children demonstrates that CAT may be performed with negligible risk, although sedation and restraint are essential to the successful performance of studies in children under 6 years of age. CAT is the preferred initial diagnostic method in suspected hydrocephalls and is accurate in the detection and precise localization of brain tumors. The management of hydrocephalus and brain tumors has been significantly altered by the availability of CAT. Few invasive neuroradiologic procedures are required and pneumography is especially curtailed. Serial scanning is the best available method of monitoring ventricular alterations in hydrocephalus, tumor size during radiotherapy or chemotherapy, and postoperative recurrence of benign neoplasms. Complex intracranial anomalies are detectable with computerized tomography, but complete definition of pathology often requires angiography and air studies. Limited clinical experience in detecting neonatal intraventricular hemorrhage suggests that CAT will be a valuable tool for futlre investigations of that problem.

An analysis of the first one thousand cerebral ACTA scans.

The first 1000 ACTA Scans of the brain are analyzed. ACTA Scanning is ideal for evaluating the ventricular system and other CSF containing spaces. High density lesions, such as intracerebral hematomas are depicted with great consistency. The method is less reliable for detecting subdural hematomas. For brain tumor screening, intravenously applied contrast agents are mandatory, so that tumors with subtle density changes can be identified more positively.

Computed tomographic evaluation of aortic aneurysms.

Applications of computed tomography are being extended from the brain to other body parts. This report describes CT scanning of abdominal and thoracic aortic aneurysms in 30 patients. CT shows greatest promise in abdominal aortic scanning, where reliable identification of the aorta can be achieved even in the absence of enlargement or calcification. However, current limitations prevent visualization of internal detail such as intimal plaques or mural thrombi. Technical advances are described which should have an important bearing on this.

Computerized axial tomography in syringomyelia.

The ACTA-scanner, a device for computerized axial tomography, permits cross-sectional radiographic study of the entire human body, including the spine. In the ACTA-scan, the spinal cord appears as a roundish formation surrounded by the less dense subarachnoidal cerebrospinal fluid. The spines of 18 patients with verified (nine cases) or suspected (nine cases) syringomyelia were studied by ACTA-scanning. In seven of the verified and in four of the nonverified cases, some evidence of cord cavitation was shown. The cystic part of a cervical-cord ependymoma was also demonstrated. ACTA-scanning is an easily performed, noninvasive, innocuous procedure. This technic, which complements other radiographic methods of evaluating the spinal cord, is particularly suitable for screening and follow-up study of patients with syringomyelia. The easily accomplished recognition of a possible associated hydrocephalus is an added advantage of ACTA-scanning.

Early clinical experience with the ACTA scanner.

An alternative method of computed tomography has been devised employing a new instrument, the ACTA scanner. This is a total-body scanner which permits study of virtually all body parts, since a water medium is not employed. Early clinical experience with this new method is discussed, and normal and pathological scans are presented.
