Rationale and Objectives Diffraction-enhanced imaging (DEI) is a new x-ray imaging modality that differs from conventional radiography in its use of three physical mechanisms to generate contrast....

Rationale and Objectives To evaluate and compare the accuracy of cross-sectional imaging using an intravascular antenna in the context of vascular morphological measurements performed during a mag...

Rationale and Objectives Most studies of computer-aided detection (CAD) for pulmonary nodules have focused on solid nodule detection. The aim of this study was to evaluate the performance of a com...

Rationale and Objectives A phantom set was devised to evaluate capability of independent component analysis (ICA) as an image filter for magnetic resonance (MR) images to segregate components. Ma...

Rationale and Objectives To determine whether angled gantry acquisition might be used to image the heart with a shorter scan length and reduced breast exposure during coronary computed tomography ...

For the past several years in our dotage, we have had two homes. For many Americans, what was a delight has become a dilemma since the crash in investments and the rise in unemployment. So far, we ...

Computed tomographic colonography (CTC), also known as virtual colonoscopy, is entering a new era. With the recent publication of the successful American College of Radiology Imaging Network Nation...

Rationale and Objectives Although spin-echo (SE) sequence has some advantages over gradient-echo sequence in brain imaging, gradient-echo sequence is commonly used for T1-weighted imaging (T1WI) a...

Rationale and Objectives Sodium magnetic resonance imaging (MRI) of the kidneys has been used to spatially map areas of sodium-concentrating activity and to quantify the corticomedullary sodium gr...

Rationale and Objectives It is well known that synchronous cancers (incidence, 2%–11%) and polyps (incidence, 12%–58%) occur in patients with colorectal cancer. Magnetic resonance colonography (MR...
