Bolus nephrotomography in diagnosis of lesions of kidney.

Bolus nephrotomography was employed in the study of 100 patients with renal adenocarcinoma and 100 patients with renal cyst. A retrospective review of the vascular and nephrographic phases of this study was made. A diagnosis of renal adenocarcinoma could be made with confidence by bolus nephrotomography in 82 per cent of cases with the remaining cases indeterminate and requiring further investigation; the vascular phase was of greater diagnostic value than the nephrographic phase. A diagnosis of renal cyst could be made with confidence by bolus nephrotomography in 85 per cent of cases with the remaining cases indeterminate and requiring further investigation; the nephrographic phase was of greater diagnostic value than the vascular phase.

Computed tomography of the body: initial clinical trial with the EMI prototype.

A review of the first 400 cases examined on one of three prototype EMI body scanners is presented. During the initial evaluation phases, it became obvious that computed tomography of the body has tremendous potential in the evaluation of various organs and disease states. The technique has been most useful in evaluating patients with known or suspected abdominal neoplasm, particularly lesions of liver, pancreas, retroperitoneum, and kidney. Too few cases have been studied to realistically quantitate its impact on the total field of medical diagnostic imaging.

Genitourinary involvement in chronic granulomatous disease of childhood.

A second case of symptomatic renal involvement of chronic granulomatous disease of childhood is reported, and all previous cases of documented genitourinary lesions in this disease are reviewed. Although frequent infections of other organ systems are a well recognized part of chronic granulomatous disease, involvement of the urinary tract has been rarely reported. The nature of the few cases described suggests that extensive insidious destruction occurs before urinary tract involvement is clinically suspected.

Initial clinical experience with computerized tomography of the body.

Computerized tomography of the body, now possible with an instrument that can complete a scan rapidly enough to permit patients to suspend respiration, adds an important new dimension to radiologic diagnosis. Cross-sectional antomy is uniquely reconstructed to provide accurate diagnostic information for various disorders throughout the body.

Urinary tract tomography.

The application of the priniciples of linear tomography to enhance the visualization of the kidneys during excretory urography represents a major advancement in the quality of excretory urography. The ability to visualize the renal parenchyma and renal outlines on tomograms has resulted in a significant increase in the detection of renal masses, parenchymal scars, and adrenal tumors. The use of tomography may also contribute significantly to the evaluation of patients with various other urinary tract diseases. It has been our practice during the past 5 years to obtain linear tomograms as a routine procedure during excretory urography in all adults and in selected pediatric patients. We believe that tomograms of the kidneys represent an important part of the excretory urogram and should be done as a routine procedure.

Excretory urographic localization of adrenal cortical tumors and pheochromocytomas.

An excretory urographic evaluation of 124 surgically proved adrenal tumors comprising 65 pheochromocytomas, 36 cortical adenomas and 23 cortical carcinomas is reported. The addition of linear tomography improved the diagnostic accuracy over conventional excretory urography. All types of tomographic examinations demonstrated at least 70% of adrenal tumors. Excretory urographic procedures are relatively safe, simple and economical and should be used as the initial step in attempting to localize clinically suspected and chemically diagnosed adrenal tumors.

Vesicoureteral reflux in adults.

Vesicoureteral reflux was detected in 200 adults seen in a 4 year period. In group 1 (no history of urinary tract infection and negative urine cultures), all patients had abnormalities on excretory urograms that were suggestive of reflux. In patients with a history of recurrent urinary tract infection (groups 2 and 3), the excretory urograms showed an abnormality in 79 per cent of those with negative cultures and in 83 per cent of those with positive cultures. Thus, reflux should be suspected in patients with a history of recurrent urinary tract infection even if infection cannot be documented with urine culture. Urographic evidence of renal parenchymal scarring, ureteral dilatation, or mucosal striations should also suggest the possibility of vesicoureteral reflux even when the patient may have no urinary tract symptoms. Voiding cystourethrography should be performed in all adults with these findings to exclude the possibility of vesicoureteral reflux.
