OBJECTIVE The objective of our study was to prospectively compare the diagnostic value of sonography and contrast-enhanced sonography with CT for the detection of solid organ injuries in blunt abdominal trauma patients. SUBJECTS AND METHODS Sonography, contrast-enhanced sonography, and CT were performed to assess possible abdominal organ injuries in 69(More)
PURPOSE To prospectively compare the sensitivity and specificity of ultrasonography (US) with those of contrast material-enhanced US in the depiction of solid organ injuries in children with blunt abdominal trauma, with contrast-enhanced computed tomography (CT) as the reference standard. MATERIALS AND METHODS The study protocol was approved by the ethics(More)
Sacroiliitis is an indispensable condition for the diagnosis of ankylosing spondylitis according to the present criteria and is usually diagnosed on standard anteroposterior radiographs of the pelvis. In cases with suspicious abnormalities (grade 1 of the New York criteria) CT permits the diagnosis since it shows a higher degree of sacroiliitis. MRI is(More)
The aim of the study was to evaluate the diagnostic capability of contrast-enhanced ultrasonography (CEUS) in a large series of patients with blunt abdominal trauma. We studied 133 haemodynamically stable patients with blunt abdominal trauma. Patients were assessed by ultrasonography (US), CEUS and multislice computed tomography (MSCT) with and without(More)
The scrotum is a superficial structure and clinical examination is frequently not enough for making a specific diagnosis. In acute scrotal pain US can confirm the presumptive clinical diagnosis and provide additional relevant information. In testicular torsion, color-Doppler imaging has a central role since it has become possible to identify it at early(More)
Sonography is widely used in the initial diagnostic assessment of blunt abdominal trauma in adults and children. It has been formally incorporated worldwide into the routine armamentarium available for emergency diagnosis and treatment as a means of rapid detection of free abdominal fluid, normally referred to as FAST (Focused Assessment with Sonography in(More)
Sixty-three hypertensive patients with probability of obstructive renal artery disease underwent both Captopril renal scintigraphy (CRS) and echo-Doppler flowmetry (EDF) before undergoing renal angiography. Angiography revealed renal artery stenosis (RAS) in 42 patients (unilaterally in 26 and bilaterally in 16). The sensitivity and specificity in the(More)
BACKGROUND The cause of musculoskeletal symptoms in the proximal extremities of patients who have polymyalgia rheumatica is not completely understood. The diffuse and severe discomfort can only be partially explained by the mild joint synovitis that is observed in these patients. OBJECTIVE To determine the involvement of the synovial structures of the(More)
The male urethral imaging and pathology is not widespread in the radiology literature because this part of the urinary tract is easily studied by urologists with clinical or endoscopic examinations. Ultrasonography and MR imaging are increasingly being used in association with voiding cystourethrography and retrograde urethrography. The posterior urethra is(More)
OBJECTIVE To evaluate the frequency and the clinical characteristics of distal extremity swelling with pitting edema in patients with psoriatic arthritis (PsA). METHODS This was a case-control study of consecutive outpatients with PsA (old and new diagnosis) observed over a 3-month period in three secondary referral centers in Italy. As controls we used(More)
