Computed tomography-guided biopsy. I. Overview.

The authors are preparing a series of communications on CT-guided biopsy procedures to be published in future issues of this journal. The present article, which previously appeared in the Cleveland Clinic Quarterly, is intended to serve as an introduction to the concept of CT-guided biopsies. Because the principles of the biopsy procedure remain the same, we do not believe that a "rewrite" of the previously published article would be required. We hope that by presenting this article and subsequent articles concerning the use of CT-guided biopsies, the reader will acquire an appreciation of the proper role of this exciting new technique in comparison to the available imaging modalities. We believe that as individuals become more experienced with the imaging capabilities of these CT devices, they will want to develop the technique of obtaining biopsy confirmation of the imaging diagnosis.

Body computed tomography: a clinically important and efficacious radiologic procedure.

In the institutions represented by the authors, more than 7,500 body CT examinations have been performed. Body CT has been found to be particularly useful in solving specific problems, especially when other diagnostic procedures yield confusiing results. Radiologists and their collegues, and not governmental agencies and insurance companies, should define the experimental, research and clinical usefulness of computed tomography.

Definitive role of CT scanning of the pancreas. The second year's experience.

In a group of 188 patients, 192 computed tomographic (CT) scans of the pancreas were done, and the diagnostic accuracy of CT determined relative to other modalities. CT was the most effective method of detecting neoplastic and inflammatory diseases. The full extent of the disease process, including involvement of the retroperitoneum and metastasis to the liver, was visualized with one examination. Calcification and cystic collections associated with pancreatitis were also clearly seen.

CT detection and aspiration of abdominal abscesses.

Computed tomography (CT) is effective in detecting intraabdominal abscesses. Loculations of fluid and extraluminal gas are clearly localized in relation to other organs. Of 22 abscess in this series, CT successfully detected 20; comparative information with gallium, techneticum, and ultrasound scans is presented. In addition to localizing these collections, CT can be used to guide needle aspiration and drainage procedures. Three sizes of needles were used to aspirate specimens and/or provide drainage. This was accomplished successfully in 12 of 14 CT-guided procedures.

Computed tomography in the detection of juxtasellar lesions.

One thousand consecutive computed tomograms were reviewed to determine the accuracy of the procedure in the detection of juxtasellar lesions. The detection rate was compared to those of plain skull films, radionuclide studies, angiography, and pneumoencephalography. Computed tomography was slightly superior to angiography and was surpassed only by pneumoencephalography, both of which are invasive procedures which carry a definite risk. The data indicate that computed tomography is the screening method of choice in the detection of juxtasellar masses.

On cats and the territorial imperative.

Of all the medical innovationes of our era, computed tomography is undoubtedly one of the most fascinating, and many nonradiologists are seeking entry into the field. If CT is to remain a radiological specialty, we must act to ensure that our training and experience are adequate to meet this new challenge.

Determination of bone mineral content using CT scanning.

The usefulness and accuracy of CT scanning in the determination of bone mineral content is studied. The radius in 31 patients of both sexes and varying ages was examined using both the Norland-Cameron bone mineral analyzer and the CT scanner. There was reasonably good correlation (r=.72). Ten cadaver bones were then examined with CT scanning and were sent to the laboratory for calcium determination. These results indicate excellent correlation (r=.97). It is concluded that CT scanning represents the only practical and accurate in vivo method of bone mineral content determination.

Computed tomography of the thorax and abdomen; a preliminary report.

The utility of computed tomography (CT) in the study of the anatomy, physiology, and pathology of the human body has been the subject of considerable interest since the introduction of CT scanning. The advent of a new prototype scanning device has made it possible to examine a variety of abnormalities in the abdomen and thorax in a manner not previously possible. This development permits a remarkable insight into the study of human disease in vivo.
