The ultrasound microdubble contrast in the diagnosis and the decisional iter of the treatment of the traumatic spleen lesions
To estimate our 3-year experience on the diagnosis and monitoring of the spleen traumatic lesions with the employment of ultrasound microbubbles contrast. From the 174 patients who were joints to our department in regimen of urgency for abdominal traumatic lesions, we have estimated 24 patiens including our criteria. The selected patients have been subordinate to the echographic examination with microbubbles contrast and to TC multi-detector (MDCT) with contrast with multiphasic technique. The echographic examination has evidenced 4 patients with abdominal fluid deposit without spleen parenchimal damage and 8 patients with morphofunctional alterations of the spleen. After the introduction o…
Sonografic examination of epiaortic vessels in patients with peripheral vertigo
Abstract Introduction: To evaluate the utility of echo-color-Doppler ultrasonography (CDU) of extracranial brain-supplying vessels in patients with peripheral vertigo of unknown origin. Materials and methods: One-hundred-fifty-six patients (study group; 42 male and 114 female; mean age 61.86 14.14) and 161 patients (control group; 80 male and 81 female; mean age 62.31 13.69) were prospectively evaluated with CDU of extracranial brain-supplying vessels. Plaques in common and/or internal carotid artery (CA), arterial wall intima-media thickness (IMT) of common CA and peak systolic velocity (PSV) and resistive index (RI) of vertebral arteries (VA) were evaluated. Parametric (t-test) and non-pa…
Heterogeneous delayed enhancement of hepatic parenchyma after intravenous infusion of sonographic contrast agent: a new hypothesis
Purpose. The aim of this paper was to report a heterogeneous latephase hepatic enhancement pattern observed after administration of a sonographic contrast agent and to present an aetiological hypothesis for the phenomenon. Materials and methods. A total of 1,729 (1,012 women and 717 men; age range 28–82; mean age 51) patients underwent contrastenhanced sonography of the liver. The examination was performed with a low mechanical index (MI <0.09) after injection of sulphur-hexafluoride-filled microbubbles, using different fonographic equipment and different contrast-specific algorithms. Results. Heterogeneous delayed liver enhancement was observed in six patients in the late phase (180 s), wi…

Bladder tumor staging: comparison of contrast-enhanced and gray-scale ultrasound
OBJECTIVE. The purpose of this study was to evaluate the effectiveness of contrast-enhanced sonography in comparison with conventional sonography in differentiating muscle- infiltrating and superficial neoplasms of the urinary bladder. SUBJECTS AND METHODS. Conventional and contrast-enhanced sonography were performed on 34 consecutively registered patients with bladder tumors. All examinations were reviewed by two independent sonologists. At gray-scale sonography, interruption of the hyperechoic bladder wall was considered the main diagnostic criterion for differentiating superficial and infiltrating tumors. At contrast-enhanced sonography, a tumor was considered superficial when the hypoen…

Evaluation of post-treatment response of epatocellular carcinoma: comparison of ultrasonography with second generation ultrasound contrast agent and dynamic CT.
Evaluation of posttreatment response of hepatocellular carcinoma: comparison of ultrasonography with second-generation ultrasound contrast agent and multidetector CT
We evaluated the ability of one-month follow-up contrast-enhanced ultrasound (CEUS) with second-generation contrast agent in monitoring radio frequency ablation (RFA) and transcatheter arterial chemoembolization (TACE) treatments of hepatocellular carcinoma (HCC). One-hundred forty-eight HCCs were studied using CEUS: 110 nodules were treated with RFA [41/110 RFA were performed using a pretreatment and an immediate postablation evaluation using CEUS (group 1); 69/110 using only US guidance (group 2)] and 38 nodules treated with TACE. For statistical analysis, McNemar test was used. Overall complete response was observed in 107/148 nodules (92/110 treated with RFA and 15/38 with TACE). A bett…

Are pancreatic calcifications specific for the diagnosis of chronic pancreatitis? A multidetector-row CT analysis.
AIM: To retrospectively establish the most frequently encountered diagnoses in patients with pancreatic calcifications and to investigate whether the association of certain findings could be helpful for diagnosis. MATERIALS AND METHODS: One hundred and three patients were included in the study. The location and distribution of calcifications; presence, nature, and enhancement pattern of pancreatic lesions; pancreatic atrophy and ductal dilatation were recorded. Differences between patients with chronic pancreatitis and patients with other entities were compared by using Fisher's exact test. RESULTS: Patients had chronic pancreatitis (n=70), neuroendocrine tumours (n=14), intraductal papilla…
