Induction-coil magnetometers are among the most common devices for measuring both static and transient magnetic fields in accelerator spectrometer magnets. Recent developments have included an induction-coil array mounted on a sledge, which is translated mid-plane of normal-conducting This device, subsequently denoted as moving fluxmeter, used to derive field homogeneity magnet center, well gra...

Coil migration is an extremely rare but hazardous complication of aneurysmal coil embolization. Only 1 case report has described coil migration following endovascular exclusion to gastrointestinal (GI) tract. We report the experience of a case of colon penetration caused by embolization coil placed for internal iliac aneurysm. A 66-year-old man visited the Emergency Department for hematochezia ...

The α-helical coiled-coil domain is a protein structure motif with a characteristic repeat pattern well suited for computer-based prediction. Long coiled-coil proteins play an important role in organizational and regulatory processes within cells and have been implicated in a number of human diseases. Knowledge about plant or prokaryotic long coiled-coil proteins however has been limited to a f...

Objective. To describe asymptomatic delayed migration of a coil loop in a patient following successful coil embolization of an anterior communicating artery saccular aneurysm. Methods. A 24-year-old man with a ruptured anterior communicating artery saccular aneurysm underwent coil embolization with one helical ultrasoft coil. Results. A followup CT scan head and a cerebral angiogram one month f...

The coiled-coil protein domain is a widespread structural motif known to be involved in a wealth of key interactions in cells and organisms. Coiled-coil recognition and prediction of their location in a protein sequence are important steps for modeling protein structure and function. Nowadays, thanks to the increasing number of experimentally determined protein structures, a significant number ...

BACKGROUND AND PURPOSE Guglielmi detachable coils (GDCs) are effective in preventing rebleeding of ruptured aneurysms. To better understand the mechanism underlying this protective effect, we evaluated blood flow in aneurysms and their parent arteries before and after GDC coil placement. METHODS An 0.14-inch guidewire containing a combined pressure and thermistor sensor was inserted through a...

BACKGROUND AND PURPOSE In recurrent cerebral aneurysms treated by coil embolization, coil compaction is regarded as the presumptive mechanism. We test the hypothesis that aneurysm growth is the primary recurrence mechanism. We also test the hypothesis that the coil mass will translate a measurable extent when recurrence occurs. METHODS An objective, quantitative image analysis protocol was de...

Introduction The growing availability of high-field whole body scanners has generated increasing interest in non-proton in vivo spectroscopy, and with it, multinuclear RF coil design. In most non-proton applications, simultaneous or sequential operation at the proton frequency is required as well; proton decoupling, scout imaging, and polarization transfer methods are cases where transmission/r...

PURPOSE Several studies have demonstrated the superiority of endorectal coil magnetic resonance imaging (MRI) over pelvic phased-array coil MRI at 1.5 Tesla for local staging of prostate cancer. However, few have studied which evaluation is more accurate at 3 Tesla MRI. In this study, we compared the accuracy of local staging of prostate cancer using pelvic phased-array coil or endorectal coil ...
