BACKGROUND: The Canadian C-Spine (cervical-spine) Rule (CCR) and the National Emergency X-Radiography Utilization Study (NEXUS) Low-Risk Criteria (NLC) are decision rules to guide the use of cervical-spine radiography in patients with trauma. It is unclear how the two decision rules compare in terms...

BACKGROUND: Although radiological pneumonia is used as an outcome measure in epidemiological studies, there is considerable variability in the interpretation of chest radiographs. A standardized method for identifying radiological pneumonia would facilitate comparison of the results of vaccine trial...

The characteristics of loop-mediated isothermal amplification (LAMP) make it a promising platform for the molecular detection of tuberculosis (TB) in developing countries. Here, we report on the first clinical evaluation of LAMP for the detection of pulmonary TB in microscopy centers in Peru, Bangla...

BACKGROUND AND PURPOSE: The purposes of this study were to find the role of diffusion-weighted MR imaging in characterizing intracerebral masses and to find a correlation, if any, between the different parameters of diffusion-weighted imaging and histologic analysis of tumors. The usefulness of diff...

We used a CT program "density mask" outlining areas with attenuation values less than -910 HU, to indicate areas of emphysema on a chest CT and to provide an overall percentage of lung involvement by emphysema. The "density mask" quantitation of emphysema was previously shown to correlate well with ...

A series of nine cases of radiation myelopathy seen at the University of California, San Francisco (UCSF) is reviewed, and their treatment data converted into nominal single doses (NSD) and equivalent single doses (ED). The 1% incidence level of myelopathy in the thoracic cord is 1015 rets (ED), and...

BACKGROUND AND PURPOSE: Synthetic MR imaging enables reconstruction of various image contrasts from 1 scan, reducing scan times and potentially providing novel information. This study is the first large, prospective comparison of synthetic-versus-conventional MR imaging for routine neuroimaging. MAT...

The concentrations of primordial radionuclides (226Ra, 232Th and 40K) in commonly used building materials (brick, cement and sand), the raw materials of cement and the by-products of coal-fired power plants (fly ash) collected from various manufacturers and suppliers in Bangladesh were determined vi...

Prognosis and therapeutic decisions are often based on left ventricular ejection fraction (LVEF), which means the LVEF needs to be accurately measured. Many imaging modalities can measure LVEF. Each of these modalities is subject to measurement errors that can lead to the inaccurate calculation of L...

INTRODUCTION: Measurement of optic nerve sheath diameter (ONSD) by ultrasound is increasingly used as a marker to detect raised intracranial pressure (ICP). ONSD varies with age and there is no clear consensus between studies for an upper limit of normal. Knowledge of normal ONSD in a healthy popula...

Aducanumab is a novel disease-modifying anti-amyloid-beta (Aβ) human monoclonal antibody specifically targeted to the pathophysiology of Alzheimer's disease (AD). It was granted for treating AD in June 2021 by the United States Food and Drug Administration. We systematically analyzed available trial...

Abstract Coal-fly-ash is one of the major byproducts of coal-based power plant in which naturally occurring radioactive materials (NORMs) are drastically enriched compared to those of feed coals. Thus, improper management of fly-ash may introduce additional radioactivity to the surrounding environme...

Objective To determine the accuracy of gradient recalled echo magnetic resonance imaging in assessing deep venous thrombosis. Design This is a retrospective review of a prospective clinical experience in 216 consecutive patients studied using gradient recalled echo magnetic resonance imaging. Sixtee...

The specific activity of 222Rn, 226Ra, 232Th and 40K in drinking water of the Chittagong region of Bangladesh was measured using high resolution ? spectrometry. The specific activity of 222Rn in the drinking water ranged from 2.04 ± 0.51 to 9.39 ± 2.06 Bq.1-1 and the mean activity was 4.46 ± 1.95 Bq...

The motivation for this study was to reduce physics workload relating to patient- specific quality assurance (QA). VMAT plan delivery accuracy was determined from analysis of pre- and on-treatment trajectory log files and phantom-based ionization chamber array measurements. The correlation in this c...
