OBJECTIVE The purpose of this study was to compare the efficacy of noninvasive multidetector CT (virtual bronchoscopic images, axial CT slices, coronal reformatted images, and sagittal reformatted images) in depicting and allowing accurate grading of tracheobronchial stenosis with that of flexible bronchoscopy. MATERIALS AND METHODS Multidetector CT and(More)
OBJECTIVE To assess the sensitivity of noninvasive virtual bronchoscopy based on multirow detector CT scanning in detecting and grading central and segmental airway stenosis using flexible bronchoscopic findings as the reference standard. MATERIALS AND METHODS In a blinded controlled trial, multirow detector CT virtual bronchoscopy and flexible(More)
OBJECTIVE We assessed the value of sonography in predicting intraoperative difficulties for patients undergoing laparoscopic cholecystectomy and in identifying indicators for conversion to conventional cholecystectomy. SUBJECTS AND METHODS Upper abdominal sonography was performed (according to a checklist) in 75 consecutive patients before laparoscopic(More)
PURPOSE To report our experience with unilateral versus bilateral stent placement in the treatment of malignant superior vena cava syndrome (SVCS). METHODS The records and films of 84 consecutive patients (69 men; mean age 64+/-10 years, range 39-79) referred for stent placement in malignant SVCS were reviewed for venous compromise, technical and clinical(More)
To compare the clinical importance of extracolonic findings at intravenous (IV) contrast-enhanced CT colonography versus those at non-enhanced CT colonography. IV contrast medium-enhanced (n=72) and non-enhanced (n=30) multidetector CT colonography was performed in 102 symptomatic patients followed by conventional colonoscopy on the same day. The impact of(More)
The purpose was to identify features of malignant and non-malignant neoplastic breast disease on galactography and to estimate their predictive value. This is the largest reported study correlating galactographic morphological patterns with histopathology and the only blinded study. The study included 351 consecutive galactograms and 161 breast biopsies(More)
OBJECTIVE The aim of this study was to determine whether a new virtual colon dissection 3D visualization technique for CT colonography has a shorter analysis time and better sensitivity for detection of colonic polyps than interpretation of axial CT images. SUBJECTS AND METHODS. CT colonography was performed in 22 patients using 4-MDCT followed by(More)
PURPOSE To evaluate superselective embolization therapy for the management of arterial damage in patients with severe renal trauma. MATERIALS AND METHODS Nine consecutive patients with renovascular injuries after blunt trauma underwent superselective embolization. Six patients had pseudoaneurysms or traumatic arteriovenous fistulas. Three patients had(More)
PURPOSE To assess the value of superselective embolotherapy of pulmonary arteriovenous malformations (PAVMs) with coaxial microcatheters and 0.018-inch microcoils and to evaluate the technique of filling the venous sac with Guglielmi detachable coils (GDCs). MATERIALS AND METHODS Six consecutive patients (three men, three women; mean age, 46 years, age(More)
BACKGROUND Renal artery stenosis (RAS) is a cause of end-stage renal failure. We studied the effect of percutaneous renal artery intervention (PRI) in patients with advanced, progressive disease at risk for renal failure, hypothesizing a beneficial effect. METHODS Thirty-nine primary and 14 secondary PRIs were performed on 28 patients with atherosclerotic(More)
