BACKGROUND AND PURPOSE Semiautomatic measurement of ICA stenosis potentially increases observer reproducibility. In this study, we assessed the diagnostic accuracy and interobserver reproducibility of a commercially available semiautomatic ICA stenosis measurement on CTA and estimated the agreement among different software packages. MATERIALS AND METHODS We analyzed 141 arteries from 90 patie...

AIMS Because the classification of congenital bicuspid aortic valve (BAV) is of importance to predict a possible valvular dysfunction, we sought to assess the feasibility, the reproducibility, and the accuracy of three-dimensional transthoracic echocardiography (3D-TTE) to accurately depict the morphology of the leaflets in a BAV. METHODS AND RESULTS Seventy-two consecutive children, who were...

BACKGROUND Atrial fibrillation (AF) is a common supraventricular arrhythmia. ECG-gated MDCT seems to be currently a method of choice for pre-ablation anatomical mapping due to an excellent resolution and truly isotropic three-dimensional nature. The aim of this study was to establish the between-subject variability and inter-observer reproducibility of anatomical evaluation of the pulmonary vei...

Despite the many studies on venous haemodynamics using duplex, only a few evaluated the normal values, variability and reproducibility. Therefore, the range and variability of venous diameter, compressibility, flow and reflux were measured. To obtain normal values, 42 healthy individuals (42 limbs, 714 vein segments) with no history of venous disease were scanned by duplex. To determine the rep...

OBJECTIVE Contemporary free-breathing non contrast enhanced cardiovascular magnetic resonance angiography (CMRA) was qualitatively and quantitatively evaluated to ascertain the reproducibility of the method for coronary artery luminal dimension measurements. SUBJECTS AND METHODS Twenty-two healthy volunteers (mean age 32 +/- 7 years, 12 males) without coronary artery disease were imaged at 2 ...

BACKGROUND The presence and extent of late gadolinium enhancement (LGE) has been associated with adverse events in patients with hypertrophic cardiomyopathy (HCM). Signal intensity (SI) threshold techniques are routinely employed for quantification; Full-Width at Half-Maximum (FWHM) techniques are suggested to provide greater reproducibility than Signal Threshold versus Reference Mean (STRM) te...

AIM To assess the reproducibility of pelvic floor biometric parameters by translabial three-dimensional ultrasound compared with the OmniView® reformatting technique. MATERIAL AND METHODS We performed a cross-sectional study involving 47 nulliparous women without symptoms of pelvic floor dysfunction. The hiatal area and right pubovisceral muscle width measurements were performed in the axial ...

PURPOSE To assess the effect of applying a protocol for image selection and the number of images required for adequate quantification of corneal nerve pathology using in vivo corneal confocal microscopy (IVCCM). METHODS IVCCM was performed in 35 participants by a single examiner. For each participant, 4 observers used a standardized protocol to select 6 central corneal nerve images to assess ...

OBJECTIVE The objective of this study was to compare inter- and intra-observer agreement using the Garnavos and AO/ASIF systems for classifying humeral diaphysis fractures . METHODS Eighty X-ray images taken of humeral diaphysis fractures in adult patients (age≥18 years) between January 2013 and September 2015 in the Radiology Department of Hospital São Paulo were selected for subsequent clas...
