Computed Tomography of the Adrenal Gland

Computed tomography (CT) easily and accurately demonstrates both the normal and abnormal adrenal gland. The normal adrenal gland can be seen in almost 95% of patients. With this technique, 29 of 29 proved adrenal masses were demonstrated; one case of bilateral adrenal hyperplasia could not be recognized, another showed equivocal enlargement. CT is an excellent screening and often definitive radiologic test of evaluating the adrenal gland.

Efficacy of Routine Screening and Lateral Chest Radiographs in a Hospital-Based Population

Abstract A prospective study of chest roentgenographic examinations was conducted to determine if the elimination of some examinations or films often routinely obtained might be medically and econo...

Computed tomography of the kidney.

Computed tomography is an extremely accurate method of obtaining more definitive diagnostic information about a renal mass discovered on a urogram. Benign renal cysts are readily distinguished from solid renal neoplasms, and CT is often valuable in characterizing possible juxtarenal masses. The cause of a nonfunctioning kidney(s) on a urogram can often be discerned, and hydronephrosis is easily detected.

Percutaneous Transthoracic Aspiration Needle Biopsy

An experience based on 1,211 patients has shown aspiration needle biopsy to be a valuable technique for diagnosing bronchogenic carcinoma and other localized intrathoracic lesions that are beyond the reach of the fiberoptic bronchoscope. In 896 patients with malignant intrathoracic neoplasm, the aspirate demonstrated malignant cells in 96%. A false cytological diagnosis of carcinoma occured in 2 patients, for a true positive rate of 99%. However, the true negative rate was only 87%. In 77% of 31 immunosuppressed patients, the causative agent of a focal infectious process was diagnosed. Pneumothorax was the only notable complication, occuring in 24% of patients, with 14% requiring chest tube drainage. The procedure is relatively simple and rapid, generally causes little patient discomfort, and can be performed in virtually any hospital.

Accuracy of computed tomography of the liver and biliary tract.

Computed tomography (CT) is a highly accurate method of detecting and clarifying the nature of space-occupying lesions within the liver. Obstructive (surgical) jaundice can be differentiated from nonobstructive (medical) jaundice very accurately using CT scanning; when obstruction is present, its level and cause can often be diagnosed. CT is not a sensitive method of detecting hepatocellular disease. Sources of error in CT scan interpretation are analyzed.

Early Clinical Experience with Motionless Whole-Body Computed Tomography

A new computed tomographic body scanner, capable of completing a scan in 18 sec., produces dramatically clearer and more precise pictures of the abdomen and thorax than heretofore possible. Other technical improvements result in increased clarity in areas of the body not affected by motion, including the brain. Potential clinical uses are illustrated.

Computed Tomographic Evaluation of the Pancreas

Computed tomography (CT) was used to assess possible pancreatic disease in 352 patients. It was found to be a reliable, often specific, and noninvasive method for detecting pancreatic neoplasms and pseudocysts. The use of CT has resulted in the diminished use of pancreatic angiography; effects of CT on patterns of utilization of other diagnostic methods are described.

Computed tomography in the staging of testicular neoplasms.

Twenty-six patients with primary testicular tumor were evaluated by computed tomography. It was highly accurate in differentiating lymph node metastases from testicular tumors. CT scanning may reveal tumor in lymph nodes not normally opacified during bipedal lymphangiography. It can also be used in treatment planning, follow-up, and in localizing sites of recurrence when serum tumor markers become positive. Some pitfalls of CT are also discussed.

High resolution computed tomography in the staging of carcinoma of the larynx

The normal anatomy of the larynx as displayed on computed tomography is illustrated. Pathological alterations in patients with carcinoma of the larynx are depicted and discussed.
