We studied the reproducibility of ultrasonographic screening examination of the hip when read by diagnostic radiographers. In order to determine interobserver variability, 200 ultrasonograms were classified according to Graf's method by five observers (four radiographers and one radiologist). The kappa values for interobserver variability indicated moderate agreement (kappa 0.47) for the exact ...

BACKGROUND Fine-needle aspiration biopsy (FNA) of the abdominal fat pad is a minimally invasive procedure to demonstrate tissue deposits of amyloid. However, protocols to evaluate amyloid in fat pad aspirates are not standardized, especially for detecting scant amyloid in early disease. MATERIALS AND METHODS We studied abdominal fat pad aspirates from 33 randomly selected patients in whom sub...

AIM The aim of this preliminary study was to test the reliability of radiographic evaluation of features of endodontic interest using a newly devised data collection system. METHODOLOGY Twelve endodontic MSc postgraduate students and one specialist endodontist examined sample radiographs derived from a random selection of 42 patients seen previously on an Endodontic New Patient Clinic (EDI). ...

PURPOSE To assess the reproducibility and agreement of anterior chamber measurements between the Pentacam (PTC) and the Anterior segment optical coherence tomography (AOCT) in normal healthy eyes with open angle. METHODS Prospective cross-sectional comparative case series. A total of 162 eyes of 81 healthy volunteers with normal open angle were included in this study. Anterior chamber angle (...

BACKGROUND Measurements of range of motion play a key role in shoulder research. The purpose of this study is to investigate intra-observer reproducibility of measurements of active and passive range of motion in patients with adhesive capsulitis. METHODS The study was carried out in a population consisting of 32 patients with clinical signs of adhesive capsulitis. A specified measurement pro...

An interactive computer system has been developed for evaluating cytologic features derived directly from a digital scan of breast ne needle aspirate (FNA) slides. The system uses computer vision techniques to analyze cell nuclei and classi es them using an inductive method based on linear programming. A digital scan of selected areas of the aspirate slide is done by a trained observer, while t...

BACKGROUND Although echocardiography is a useful and cost-effective technique for the detection of morphological and functional cardiac abnormalities, it has a main limitation in its subjectivity. Therefore the aim of the present study was to assess the intra-observer reproducibility and validity of 2-dimensional guided M-mode echo measurements at a Nigerian metropolitan Hospital. METHODS Sta...

INTRODUCTION There is limited evidence regarding intra-observer and inter-observer variations in echocardiographic measurements of diastolic function. This study aimed to assess this reproducibly within a population-based cohort study. METHODS Sixty subjects in sinus rhythm were randomly selected among 4th visit participants of the STANISLAS Cohort (Lorraine region, France). This 4th examinat...

BACKGROUND Parameters of myocardial deformation have been suggested to be superior to conventional measures of ventricular function in patients with tetralogy of Fallot (ToF), but have required non-routine, tagged cardiovascular magnetic resonance (CMR) techniques. We assessed biventricular myocardial function using CMR cine-based feature tracking (FT) and compared it to speckle tracking echoca...

The gold standard for measuring knee alignment is mechanical axis determined using full-limb radiographs (FLR). Measurement of joint alignment using antero-posterior (AP) knee radiographs is more accessible, economical and involves less radiation exposure to the patient compared with using full-limb radiographs. The aim of this study was to compare and assess the reproducibility of knee joint a...
