We retrospectively evaluated 21 patients with Budd-Chiari syndrome who underwent liver transplant. The pathological findings were correlated with imaging studies that included computed tomography (CT) in all cases, sonography in 20, and magnetic resonance (MR) in 15. Pathological features of Budd-Chiari syndrome in subacute or chronic form, such as(More)
Over a 7-month period, from a total of 417 transrectal ultrasound (US) studies, 45 transperineal biopsies of the prostate were performed in the radiology department. Transrectal US guidance and local anesthesia were used. Twenty-two of 32 hypoechoic lesions, located within the peripheral zone tissue of the gland, were proved by histologic study to be(More)
Adenocarcinoma of the prostate produces specific ultrasonic findings that can be used in diagnosis. We have examined 211 patients using transrectal ultrasound in both the sagittal and axial planes. Thirty-three carcinomas were detected, and 31 histologically confirmed; 24 by needle biopsy, six by transurethral resection, one by total prostatectomy, and two(More)
We studied the efficiency with which clinicians were able to obtain the results of radiologic studies during visits to the radiology department in an effort to determine how often delays occurred and, if so, how they were perceived to have influenced patient care. We monitored 322 physician's visits to four locations within the radiology department in(More)
Leukemic involvement of ovary has been found in up to 30% of patients with acute lymphocytic leukemia (ALL) at autopsy, but is rarely found clinically. Since the ovary may be a sanctuary for ALL to reseed the marrow, early clinical detection of ovarian involvement is important. The use of sonography in evaluating the ovary is suggested as part of the(More)
OBJECTIVE The purpose of this study was to compare observer performance in interpreting high-quality, digitally acquired computed radiographs of the chest displayed on either laser-printed radiographs or a workstation with observer performance in interpreting conventional chest radiographs. SUBJECTS AND METHODS We performed a(More)
BACKGROUND The aim of the present study was to measure the influence of a defined period of standardised voluntary hyperventilation on the levels of glucose, free fatty acids and several glucose regulating hormones in healthy volunteers. STUDY DESIGN Eight healthy male subjects were submitted to 20 minutes of controlled hyperventilation and blood levels(More)
