Aspiration Biopsies of Chest Lesions

1223 patients underwent aspiration biopsy with a diagnostic yield of 86.4%; 24.2% of the patients had a small pneumothorax, but only 4.4% required treatment; one patient developed a moderate hemothorax. The method, problems, and complications including morbidity and mortality are discussed. The relative success of aspiration biopsy with different lesions of the lung and mediastinum is identified.

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.

The floating aorta in computerized tomography: A sign of retroperitoneal pathology

Abstract The diagnosis of retroperitoneal disease including mass lesions has been a difficult one to make in the past and many conventional radiologic modes, including arteriography, ultrasonography, excretory urography and lymphangiography, have been used. A reliable sign of retroperitoneal pathology is anterior displacement of the abdominal aorta which was previously described utilizing lateral roentgenology (1), arteriography, (2) and ultrasonography (3).

Pseudocyst of the pancreas with perirenal extension: Demonstration by computed tomography

Abstract An uncommon case of a patient with a pseudocyst of the pancreas clinically mimicking a renal mass is demonstrated by CT including the extent of dissection. Once the cyst in the pancreas was known, other radiographic methods helped to confirm the diagnosis. A review of the literature concerning pseudocyst extension to the kidney is also presented.

Computerized tomography-guided percutaneous transhepatic biliary drainage

Abstract With the introduction of computed tomography (CT) of the body, an excellent cross-sectional image display of the various organ systems within the abdomen became available. As a result, it soon became apparent that with the use of computed tomography percutaneous aspiration biopsies could be facilitated (1). Using computed tomography guidance it is now possible to accurately place a biopsy instrument within virtually any organ in the abdomen. CT-guided needle procedures are useful not only for the purpose of diagnosis, but are valuable as a therapeutic tool in selective patients. We wish to describe a method of computed tomography-guided percutaneous transhepatic biliary drainage which we have utilized in five patients to accomplish definitive relief of obstructed biliary systems. Each of our patients had an inoperable carcinoma either in the head of the pancreas or in the region of the porta hepatis which resulted in obstruction of the biliary system.

In vivo Determination of Bone Density âàA Comparative Study

Two in vivo methods for the determination of bone mineral content are compared. It is concluded that computed tomography represents the only accurate in vivo method capable of determining bone mineral content per volume of bone. In addition, it has the distinct advantage of being able to determine the bone mineral content of virtually any bone of the skeleton.
