Abstract Background Accurate repeat assessment of the diameter an abdominal aortic aneurysm (AAA) is important. This study investigated reproducibility different methods measuring AAA from ultrasound images. Methods Fifty patients were assessed by ultrasound. Maximum was measured independently three trained observers on two separate occasions using a standardised protocol. Five diameters each s...

Aims-To arrive at a reproducible sampling technique for counting apoptotic cells in tissue sections of invasive breast cancer that can serve as a protocol for further clinical studies.Methods-In 4 mum thick haematoxylin and eosin stained tissue sections of 12 breast cancers, apoptotic cells, recognised by strict morphological criteria, were counted in consecutive fields of vision at x1000 magni...

Introduction: Advances in image quality from modern Dual Energy X-ray absorptiometry (DXA) scanners now allow near radiograph-like quality images at a low radiation dose. This opens potential new applications for the use of DXA scanners to study other musculoskeletal conditions, such as osteoarthritis which is often investigated by visual assessment of radiographs. Together, osteoporosis and os...

Intraobserver and interobserver reproducibility of the FAB classification was assessed for two independent observers whose decisions are acted on for treatment of patients with acute leukemia in the Hamilton region. Intraobserver reproducibility was assessed for Wright-stained preparations that were examined independently on two consecutive occasions at least 2 weeks apart. A third reading was ...

BACKGROUND The first sign of plantar sensory impairment due to aging and peripheral neuropathies are manifested on the soles of the feet and can result in postural control and balance deficits. The aim of cutaneous sensitivity tests is to assess the skin sensory innervation density such as those of the distal segments. In some studies the two-point discrimination test (TPD) have been applied on...

BACKGROUND Central obesity poses a significant risk for cardiovascular diseases, but the reproducibility of manual measurements of waist and hip circumferences has been questioned. An automated 3D body scanner that uses white light rays could potentially increase the reliability of these anthropometric measurements. METHODS We assessed the reproducibility of anthropometric measurements perfor...

OBJECTIVE To evaluate the reproducibility of the calculation of breast density with DM-Scan software, which is based on the semiautomatic segmentation of fibroglandular tissue, and to compare it with the reproducibility of estimation by visual inspection. MATERIAL AND METHODS The study included 655 direct digital mammograms acquired using craniocaudal projections. Three experienced radiologis...

INTRODUCTION Glenoid component loosening is the main complication of total shoulder arthroplasty. Better knowledge of the arthritic glenoid cavity anatomy can help in developing new implants and techniques. The goal of this study was to describe and validate the reproducibility of a CT scan-based, 3D measurement method used to describe various parameters characterizing arthritic glenoid cavity ...

BACKGROUND We sought to determine the intra- and inter-radiation therapist reproducibility of a previously established matching technique for daily verification and correction of isocenter position relative to intraprostatic fiducial markers (FM). MATERIALS AND METHODS With the patient in the treatment position, anterior-posterior and left lateral electronic images are acquired on an amorphou...
