Abdominal Radiology > 2016 > 41 > 11 > 2218-2226

Purpose To compare image quality (IQ) and patient discomfort during prostate MRI using a pelvic phased array (PPA) coil and an endorectal (ER) coil. Materials and methods Ninety-eight patients (median age, 65.7; range 42.1–78.1) underwent prostate MRI on a 3T scanner including T2w and DWI acquired with PPA and an ER coil within the same exam. Acquisition time was kept similar for both acquisitions...

Fibular nerve palsy after hip replacement: Not only surgeon responsibility. Hereditary neuropathy with liability to pressure palsies (HNPP) a rare cause of nerve liability

G. Logroscino, F. Del Tedesco, C. Cambise, D. Coraci, more

Orthopaedics & Traumatology: Surgery & Research > 2016 > 102 > 4 > 529-531

Mononeuropathy after surgery may occur and hereditary neuropathy with liability to pressure palsies is a possible pathological condition related to paresis after hip surgery. We present a case of 66-year-old man presenting severe weakness at inferior limb muscles after hip prosthesis revision. Clinic and electrophysiology showed severe right fibular nerve damage and ultrasound found a marked enlargement...

Imaging the Magnetic Topologies of Cool Active Stars

J. -F. Donati

Lecture Notes in Physics > Astrotomography > 207-231

In the last decade, new indirect imaging techniques have been proposed to unveil the surface magnetic topologies of rapidly rotating active stars, which are found to be vastly different from that of the Sun. After a quick recall of how direct magnetic field (i.e. spectropolarimetric) signatures can be detected in such stars, I describe in detail to which extent surface magnetic field topologies can...

Towards magnetic images of rapidly rotating late-type stars

J. -F. Donati, M. Semel

Lecture Notes in Physics > The Sun and Cool Stars: activity, magnetism, dynamos > 326-329

We present the first magnetic detections using Zeeman-Doppler Imaging (ZDI) in the two bright rapidly rotating RS CVn systems HR 1099 and σ ² CrB, and discuss their compatibility with various recent results on magnetic activity in cool stars.

Differential Rotation of Close Binary Stars: Application to HR 1099

P. Petit, J. -F. Donati, G. A. Wade, J. D. Landstreet, more

Lecture Notes in Physics > Astrotomography > 232-237

We propose a new method for estimating differentialrotation in binary stars, for which only moderate to poor phase coverage can be obtained (rotation period of order of a few days), preventing the use of conventionalcross-correl ation methods. Assuming a solar-like differential rotation law with two independent parameters (equatorialrotation rate Ω_eq and rotationalshear between pole and equator dΩ),...

Medical Radiology

Magnetic resonance angiography (MRA) continues to undergo exciting technological advances that are rapidly being translated into clinical practice. It also has evident advantages over other imaging modalities, including better patient safety compared with CT angiography and superior accuracy and contrast resolution compared with ultrasonography. With the aid of numerous high-quality illustrations,...

Association Between Penile Dynamic Contrast‐Enhanced MRI‐Derived Quantitative Parameters and Self‐Reported Sexual Function in Patients with Newly Diagnosed Prostate Cancer

Hebert Alberto Vargas, Olivio F. Donati, Andreas Wibmer, Debra A. Goldman, more

The Journal of Sexual Medicine > 11 > 10 > 2581 - 2588

IntroductionThe high incidence of prostate cancer, coupled with excellent prostate cancer control rates, has resulted in growing interest in nononcological survivorship issues such as sexual function. Multiparametric magnetic resonance imaging (MRI) is increasingly being performed for local staging of prostate cancer, and due to the close anatomical relationship to the prostate, penile enhancement...
