Diagnosing pancreatic disease generally requires many different imaging procedures. Ultrasound and CT are most commonly used to evaluate the pancreatic ducts, parenchyma, and adjacent soft tissues. CT-based assessment of pancreatic pathology has been greatly aided by the advent of multislice technology.
MRI will continue to evolve and will remain the dominant imaging technology in medicine, according to a leading world expert on the modality.
In late November, nearly 300 doctors and imaging center managers paid $325 each for a day-long seminar sponsored by the law firm McDermott Will & Emery. They packed a large ballroom in the swank Ritz-Carlton Hotel at Water Tower Place in Chicago to learn how to turn referrals to imaging facilities into lucrative income streams.
Peripheral MR angiography (far right) is improved on first-pass imaging due to the high relaxivity of the MR blood pool agent Vasovist. The extended imaging window provided by the agent supports steady-state imaging not possible with other MR contrast media, producing ultrahigh spatial resolution MRA (second pass) demonstrating both arteries and veins in detail.
Whole-body MR imaging could complement-and, in some cases, even replace-traditional bone scanning techniques. Researchers across Europe have found that whole-body MRI has a significant impact on patient management compared with x-ray and nuclear medicine.
Striking the right balance between quality and throughput is never easy, especially when the queue of referrals seems never to end. Shorter scan times mean that another patient or two could be squeezed onto the day's work list.
Europeans are advised to follow steps outlined in the U.S. to prevent a life-threatening skin condition linked with gadolinium-enhanced MRI or MR angiography, according to a new editorial in European Radiology. The article stresses the importance of caution in high-risk patients for all gadolinium agents, not just the ones that have been associated with reactions, because the condition’s causes are still unclear.
Technical advances in MRI have paved the way for functional imaging of the abdomen, moving beyond simple morphological evaluation of disease and in some cases proving superior to multislice CT.
Multislice CT has steamed into our radiology departments like a nuclear-powered aircraft carrier. In its wake, an entire support industry has sprung up to help us quench our ever-increasing thirst for more and better slices.
MRI has proven to be a reliable, fast, noninvasive means for assessing deep fat in adults. It can also be effective in high-risk pre-adolescents and adolescents, according to a study in the March issue of Radiology.
So what do you use your 3T system for?Five years ago, that question would have been a good opening for a detailed discussion onthe strengths and weaknesses of high-field MRI.
Advances in coil technology and the development of tailored sequences have made 3T a versatile alternative to 1.5T. But it will be a long time until it displaces 1.5T as the workhorse of MR.
Recently published studies reflect the versatility of cardiac MR, multislice CT, rubidium-82 PET/CT, and stress echocardiography for shedding diagnostic light on various aspects of coronary artery disease and other cardiac conditions.
The American College of Radiology has added cardiac MRI to its growing menu of facility accreditation programs.
The current fiasco over the European Union Directive on electromagnetic fields illustrates exactly why the newly formed European Society of Radiology (ESR) is so urgently needed.
Over the last several years, imagers and patients have witnessed passionate debate, sometimes even legal action, involving breast MR imaging. Dissent has finally given way to consensus over a few key points: Breast MRI is meant to complement, not replace, mammography or sonography, and it's a handy tool to guide biopsies, assess disease before surgery, and evaluate treatment response.
Heart failure is a common disorder with high morbidity and mortality. It is the only major cardiovascular disease whose prevalence and incidence are not only on the increase but predicted to reach epidemic proportions.
European legislation aimed at protecting workers from harmful effects of electromagnetic radiation, such as that emitted by mobile phones and electrical power lines, could unwittingly change the course of MR imaging if efforts to amend the law fail, according to Prof. Gabriel Krestin, who spoke in March at a press conference at the European Congress of Radiology.
A multicenter prospective trial involving 1210 patients in Europe has found that the odds of a favorable clinical outcome were one-third higher for acute stroke patients who received diffusion/perfusion MRI to determine the appropriateness of tPA thrombolysis than for patients assessed with conventional noncontrast CT.
The feasibility of 3T MR as a general-purpose clinical imaging modality is an ongoing controversy. Although whole-body 3T MRI has been available for several years, most systems to date have been sold to university hospitals and research facilities.
Dr. Harald Ostensen, a radiologist from Norway whose reach extends all over the world, has received the European Magnetic Resonance Forum Foundation's inaugural Humanitarian Award.
Female infertility accounts for two-thirds of all infertility problems, and it can be due to tubal, ovarian, and/or uterine factors. Tuboperitoneal disease is thought to be a contributing factor to infertility for up to 40% of infertile couples.
High-intensity focused ultrasound (HIFU) has shown promise as a pain management strategy in patients with bone metastases for whom other treatments are ineffective, according to researchers at the Sheba Medical Center in Israel (Ann Oncol 2007;18:163-167).
Dr. Harald Ostensen, a radiologist from Norway whose reach extends all over the world, has received the European Magnetic Resonance Forum Foundation's inaugural Humanitarian Award. The award will be presented to him next month at a private ceremony in Potsdam, Germany.
For the first time, data accrued over a decade show that the involvement of the pharmaceutical industry in clinical breast cancer research may have significantly influenced study design, focus, and results, according to a study published in the April 1 issue of Cancer.
