It was a cold Saturday morning, snowing slightly, when I slipped into the sheriff’s office in the Boone County Courthouse, my news beat for the Columbia Daily Missourian . There were no trials, and...

Rationale and Objectives We sought to evaluate the diagnostic performance of an artificial neural network (ANN) and binary logistic regression (BLR) in differentiating malignant from benign thyroi...

Rationale and Objectives We conducted an observer study to investigate whether radiologists can judge similarities in pairs of breast masses and lung nodules consistently and reproducibly. Materi...

The following abstracts of diagnostic radiology research and training grants funded by the National Institutes of Health (NIH) were awarded to principal investigators (PIs) whose primary appointmen...

Rationale and Objectives The hyperpolarized 3 He long-range diffusion coefficient (LRDC) in lungs is sensitive to changes in lung structure due to emphysema, reflecting the increase in collateral...

In the preface, the author clearly states his objectives for this text—to teach the fundamentals of musculoskeletal ultrasound in an efficient and concise manner. The author states that emphasis sh...

Rationale and Objectives The human lung and its functions are extremely sensitive to orientation and posture, and debate continues as to the role of gravity and the surrounding anatomy in determin...

Rationale and Objectives Dynamic positron emission tomographic imaging of the radiotracer 2-deoxy-2-[ 18 F]fluoro- d -glucose ( 18 F-FDG) is increasingly used to assess metabolic activity of lu...

Rational and Objectives Pulmonary partial pressure of oxygen ( p O 2 ) and oxygen depletion rate ( R ) are two important parameters of lung function. The dependence of hyperpolarized 3 He (HP 3...

Rationale and Objectives Hyperpolarized gases such as 129 Xe and 3 He have high potential as imaging agents for functional lung magnetic resonance imaging (MRI). We present new technology offeri...
