Noninvasive visualization of coronary arteriosclerosis by computed tomography.

I report a new, extremely rapid, noninvasive technique for the diagnosis of coronary artery occlusion. An ultrafast x-ray cine-computed tomographic scanner (cine-CT) allows visualization of the coronary arteries without injection of contrast material. The arteries can be seen because of the CT contrast between blood in the arteries and the pericardial fat. This theory is supported by a study of 200 patients followed up for 5 years. This examination is extremely short and noninvasive, so it is a potentially efficient method of mass screening for coronary arteriosclerosis.

Cervical disk degeneration and herniation: diagnosis by computerized tomography.

Computerized tomography (CT), which has revolutionized the diagnosis of intracranial disease in less than a decade, has made substantial progress in spinal diagnosis in the last few years. It is rapidly becoming the preferred technique for the diagnosis of lumbar disk herniation and is applicable to cervical disk diagnosis, although there are some important technical differences. Over a three-year period my group has performed 468 cervical CT studies. A comparison between the myelographic and the CT findings in 144 of these cases indicates that CT equals the accuracy and exceeds the sensitivity of myelography in the diagnosis of cervical disk herniations.

Computed-tomographically guided percutaneous transmastoid drainage of a cerebellar abscess.

Computed-tomographic scanning demonstrated a cerebellar abscess in a patient with suppurative mastoiditis. Following radical mastoidectomy, computed-tomographically guided percutaneous drainage of the abscess resulted in substantial improvement in the patient's deteriorating neurologic condition. Because of the prior mastoidectomy, burr holes were not required for the drainage, permitting a percutaneous approach to a cerebellar lesion.

The use of three-dimensional computer display in the study of disk disease.

We have developed a software system for three-dimensional dynamic display of organs from computed tomograms (CT). We are now beginning to evaluate the clinical usefulness of this software system. We have chosen the spine in general, and disk disease in particular, as the first step in this evaluation. The choice was to a large extent influenced by our belief that surgical planning can be improved if three-dimensional displays of the diseased disk and its surroundings are available. Patients who have been referred to us for CT evaluation were examined in the routine manner. In those cases in which the ordinary CT scans indicated potential usefulness, the softwar system was applied, and movies were produced showing the appearance of appropriate parts of the spine as if they were rotating in front of the user. It appears that the size and relative location of disk herniations are well represented by such displays. Proof of efficacy in surgical planning awaits a more thorough evaluation, but our initial study indicates that the method has great promise.

Evidence of CSF enhancement in the spinal subarachnoid space after intravenous contrast medium administration: is intravenous computer assisted myelography possible?

Following intravenous injection of iodinated contrast medium, peripheral enhancement of the area inside the spinal canal, is frequently observed by computed tomography. This may be due, at least in part, to enhancement of the cerebrospinal fluid in the spinal subarachnoid space. Our preliminary observations in human patients and in animal experiments are reported. The goal of intravenous computer assisted myelography is worth pursuing.

Cerebral computed tomography in Reye syndrome.

The computed tomography (CT) findings in a case of Reye syndrome are presented. A striking discrepancy between the CT attenuation of infratentorial (elevated values) and supratentorial structures is observed.

Diving-type injury of the cervical spine: contribution of computed tomography to management.

We have utilized computed tomography (CT) in addition to conventional radiography for evaluation and as a guide to management of serious diving injuries to the cervical spine. This technique has proven to be invaluable in the initial assessment and further clinical management of this type of injury. A classification of these injuries and associated fractures is presented based on CT appearance. Representative cases are presented comparing standard radiography and CT.

Computed tomographic arteriography.

Computed tomographic arteriography is the technique of contrast enhancement by arterial perfusion during computed tomography. This technique appears to have significant advantages over conventional intravenous contrast enhancement in selected cases.

Computer assisted myelography in disk disease.

Computer assisted myelography (CAM) is a technique to examine the spinal subarachnoid space. Adjacent structures that may impinge on this space, such as the intervertebral disks, as well as structures contained in this space, such as the spinal cord, spinal roots, and vascular formation, may also be appraised by this method. At present, CAM is performed by subarachnoid introduction of water soluble contrast material followed by computed tomography in the axial transverse plane. The authors present their technique and their results with representative cases of intervertebral disk disease.

Contrast enhancement by arterial perfusion during computerized tomography.

Contrast enhancement of computerized tomography is usually performed by means of intravenous injection of iodinated contrast materials. The authors have utilized a technique of direct arterial infusion of iodinated contrast material supplying intracranial arteries during computerized axial tomography. A representative case is presented with comparison scans which were obtained without contrast enhancement and with conventional intravenous infusion of contrast. Marked improvement of the enhancement was clearly demonstrated in this case, with abnormalities readily defined that were not seen with the conventional intravenous enhancement procedure.
