Computed tomography coronary angiography in asymptomatic patients
This study assessed the accuracy of computed tomography coronary angiography (CT-CA) for detecting significant coronary artery disease (CAD; a parts per thousand yen50% lumen reduction) in intermediate/high-risk asymptomatic patients. A total of 183 consecutive asymptomatic individuals (92 men; mean age 54 +/- 11 years) with more than one major risk factor (obesity, hypertension, diabetes, hypercholesterolaemia, family history, smoking) and an inconclusive or nonfeasible noninvasive stress test result (stress electrocardiography, stress echocardiography, nuclear stress scintigraphy) underwent CT-CA in an outpatient setting. All patients underwent conventional coronary angiography (CAG) with…
Use of sulesomab in the diagnosis of brucellar spondylitis.
ABSTRACT Twenty-two patients with suspected brucellar spondylitis were investigated to evaluate the possible diagnostic role of Sulesomab, a 99m Tc-antigranulocyte antibody Fab' fragment. Sensitivity and specificity were compared with those of magnetic resonance imaging (MRI). Skeletal involvement was detected by MRI in 11 cases, while leukoscintigraphy indicated normal vertebral uptake in seven of these patients, increased uptake in two patients, and decreased uptake in two patients. Leukoscintigraphy of the 11 patients negative by MRI demonstrated increased uptake in two cases. The sensitivity and specificity of leukoscintigraphy were 27.2% and 81.1%, respectively. Based on these results,…
Contrast-enhanced second-harmonic sonography in the detection of pseudocapsule in renal cell carcinoma.
“OBJECTIVE. Our purpose was to assess the capacity of contrast-enhanced second-harmonic sonography to detect a pseudocapsule in renal masses compared with conventional gray-scale sonography. SUBJECTS AND METHODS. Thirty-two patients with 40 renal masses suspicious for renal cancer (mean diameter, 3.1 cm) were prospectively studied with contrast-enhanced second-harmonic sonography during IV administration of a second-generation sonographic contrast agent. The sonographic criteria for the presence of a pseudocapsule were a peritumoral hypoanechoic halo on conventional gray-scale imaging and a rim of perilesional enhancement, increasing in the tardive phase of the examination, on contrast-enha…
Computed tomography coronary angiography plaque burden in patients with suspected coronary artery disease.
Purpose To determine the relationship between established cardiovascular risk factors, clinical presentation and the extent of coronary artery disease (CAD), as described with computed tomography coronary angiography. Material and methods In this cross-sectional study, we included 567 symptomatic individuals without a history of CAD who consecutively underwent 64-slice computed tomography coronary angiography for evaluation of suspected CAD. We analyzed the prevalence of CAD depending on sex, age, symptoms and risk factors. Results A total of 8542 segments were analyzed. No evidence of CAD was observed in 225 patients (40%), nonsignificant CAD in 221 patients (39%) and significant CAD (lumi…
