PURPOSE The aims of this study were to determine the value of chest radiography in diagnosing lung parenchymal injury in patients with thoracic trauma, and to evaluate the frequency of lung parenchymal injury by using thoracic computed tomography (CT). MATERIALS AND METHODS Between January 2005 and June 2006, we retrospectively evaluated the(More)
OBJECTIVE To evaluate the efficacy of digital rectal examination (DRE), transrectal ultrasonography (TRUS), prostate-specific antigen (PSA) and PSA density (PSAD) in the diagnosis of prostate cancer (CaP). PATIENTS AND METHODS Retrospective data were analysed from a selected population of 159 patients (mean age 66.7 years, range 50-83), 56 with(More)
Cerebral occurrence of Echinococcus multilocularis is very rare and there is no widely accepted therapeutical method. In this report we present a case with an intracranial mass lesion and a palpable hepatic mass, which appeared to be due to Echinococcus multilocularis in the histopathological examination.
Objective: Strong relationships have been demonstrated between the presence of occlusive coronary artery disease and coronary artery calcifications detected at autopsy, fluoroscopy, or computed tomography (CT). The aim of our study was to evaluate the frequency of incidental coronary artery calcifications during thoracic CT examinations and to correlate(More)
Findings on transrectal ultrasonography (TRUS), computerized tomography (CT), and magnetic resonance imaging (MRI) in local staging of prostatic carcinoma (PCa) were compared with the final pathological staging in 30 patients who underwent radical prostatectomy. We found TRUS and MRI to have the same accuracy rate (53%) in local staging, whereas CT revealed(More)
Although the etiology of syringomyelia is not clearly understood, many surgical methods have been proposed for its treatment. One widely used technique in cases of communicating syringomyelia is that of posterior fossa decompression and plugging of the obex (Gardner's Operation). In this paper we present five cases of syringomyelia which were investigated(More)
PURPOSE The purpose of this study was to evaluate the feasibility of diffusion-weighted imaging in the diagnosis of the urinary bladder and prostate carcinomas. The apparent diffusion coefficient (ADC) values of the malignant and normal tissues were correlated. MATERIALS AND METHODS A total of 23 patients with 14 urinary bladder carcinomas and 9 prostate(More)
PURPOSE To determine the utility of diffusion tensor imaging for the differentiation of adrenal adenomas and metastases. MATERIALS AND METHODS Thirty-three patients with a mean age of 59 years were included in this study. Each subject presented with a single adrenal lesion (19 adenomas, 14 metastases). Magnetic resonance imaging (MRI) was performed in the(More)
The effect of pirenzepine on cholecystokinin (CCK)-stimulated gallbladder contraction in man was compared with that of atropine. Following pretreatment with atropine, pirenzepine or physiological saline in a random order, 6 healthy male volunteers were infused for 75 min with CCK-octapeptide in doses that are reported to mimic physiological plasma(More)
