OBJECTIVE Combined use of low-mechanical-index technologies and non-air-filled contrast media allows real-time sonographic assessment of the spleen. This pictorial essay focuses on several aspects of contrast-enhanced sonography of the spleen, including examination technique, clinical indications, normal findings obtained through all vascular phases,(More)
Transient non-obstructing intussusception is known to occur in adults. While the CT findings in small bowel intussusception have been described in detail, few reports concerning transient cases have been published. We evaluated five patients with non-obstructive jejuno-jejunal invagination. All CT studies showed a target pattern with an intraluminal soft(More)
Using data collected at the Pierre Auger Observatory during the past 3.7 years, we demonstrated a correlation between the arrival directions of cosmic rays with energy above 6 x 10(19) electron volts and the positions of active galactic nuclei (AGN) lying within approximately 75 megaparsecs. We rejected the hypothesis of an isotropic distribution of these(More)
OBJECTIVE To report our experience in the assessment of splenic trauma with contrast-coded sonography and a second-generation contrast medium. METHODS From January to May 2002, 120 patients were studied with sonography for suspected splenic trauma. Twenty-five were selected for further imaging because of sonographic findings positive for splenic injury,(More)
OBJECTIVE The purpose of this study was to compare the accuracy of unenhanced helical CT with combined sonography and unenhanced radiography in patients with acute flank pain suggestive of ureteral colic. SUBJECTS AND METHODS From January 1997 to December 1999, 181 consecutive patients with acute flank pain underwent unenhanced radiography, sonography,(More)
OBJECTIVE We describe the contrast-specific sonography features of ruptured abdominal aortic aneurysm, and we hypothesize that this technique would be useful for emergency imaging of patients with suspected aneurysm rupture. CONCLUSION We used contrast-specific sonography to assess eight patients with ruptured abdominal aortic aneurysm. Five of these(More)
PURPOSE To report our preliminary experience in the evaluation of the spleen using a real-time contrast-specific ultrasound module in combination with a second-generation contrast agent. MATERIALS AND METHODS In a 7-month period, 55 patients (34 males and 21 females, aged 5-77 years) with spleen disorders were evaluated by means of contrast-enhanced(More)
PURPOSE To report our pilot experience in the evaluation of traumatic and nontraumatic emergencies with contrast-specific, continuous-mode sonography (US) and a second-generation contrast medium. MATERIALS AND METHODS Between January 2002 and December 2003 we evaluated 126 acute patients by using real-time contrast-specific US: blunt abdominal trauma (76(More)
The objective of this study was to evaluate the concordance of US and contrast-enhanced US (CEUS) with CT in the assessment of solid organ injury following blunt trauma. Patients underwent complete US examination, including free fluid search and solid organ analysis. CEUS followed, using low-mechanical index techniques and SonoVue. CT was performed within 1(More)
BACKGROUND & AIMS The aim of this study was to prospectively compare the diagnostic yield of wireless capsule endoscopy (WCE) and enteroclysis in evaluating the extent of small-bowel involvement in Crohn's disease (CD). METHODS Thirty-one patients (20 men; mean age, 43 y) with endoscopically and histologically proven CD underwent enteroclysis as their(More)
