To determine the reliability of gray scale ultrasound in detecting urinary tract obstruction, a prospective study of 67 patients examined by both excretory urography and ultrasound was undertaken. The degree of hydronephrosis was defined by urographic criteria, and the corresponding echograms were analyzed without knowledge of the urographic results.… (More)
A gray scale ultrasound evaluation of a case of adult intussusception is presented. The observed "target-like" abdominal mass, with central dense echoes and peripheral sonolucency, may be characteristic of this entity. A primary bowel or intestinal loop process should be considered when a lesion with this appearance is encountered.
Twenty cases of sonographically visualized thickening of the gallbladder wall were reviewed and the clinical diagnoses compiled. In only eight of these patients was cholecystitis considered responsible for the finding. The rest had hepatitis, alcoholic liver disease with hypoproteinemia, heart failure, renal disease, and multiple myeloma; however, all… (More)
Spinal dysraphism refers to incomplete embryologic development of the dorsal midline. Frequently it is not clinically obvious, and lack of treatment can lead to progressive neurological damage. Early diagnosis of occult defects can allow appropriate surgical intervention and prevent neurological deficits. The authors have used high-resolution real-time… (More)
Athletes often exhibit ECG findings which are considered to be abnormal. Therefore, we used noninvasive graphic methods to study 42 active professional male basketball players, ranging in age from 21 to 31 years, without clinically evident heart disease. Of the 42, 11 (25%) met the Romhilt-Estes ECG voltage criteria for left ventricular hypertrophy, and 12… (More)
Because of the limited resolution of conventional ultrasonic B-scanning units, visualization of normal vascular anatomy in the upper abdomen has been largely restricted to the aorta. By utilizing the newer "gray scale" equipment, it is now routinely possible to demonstrate the inferior vena cava and portal veins as well as several smaller epigastric… (More)
Sonography, disappointing as a primary screening method, has emerged as the single most helpful adjunct to mammography in evaluation of the clinically and/or mammographically abnormal breast. Sonography can reliably diagnose simple cysts presenting as palpable masses or as indeterminate, nonpalpable lesions on mammography. However, differentiation of benign… (More)
