Monitoring water mobility offers an approach to cancer imaging that complements anatomy-based techniques

Any fluid-filled cavity or sac that is lined by an epithelium is a cyst, and intracranial cystic lesions are a common finding on CT and MR imaging of the brain.1,2 These lesions contain either cerebrospinal fluid, fluid that is similar to CSF, mucus, or proteinaceous fluid. They are lined by epithelial cells, inflammatory cells, or glial cells. The attenuation characteristics of the cyst on CT and MRI and the contrast enhancement patterns depend on the cyst's contents and the composition of the wall.

Results from two clinical trials demonstrate that cryoablation of renal cell carcinomas is effective at least a year after treatment in nearly all patients with lesions 4 cm or smaller. The studies suggest that cryotherapy could serve as an alternative to surgery.

The discovery process for more than 60 federal lawsuits alleging a connection between cases of nephrogenic systemic fibrosis and gadolinium-based MR contrast agents will be consolidated at a single district court in Ohio, according to a U.S. judicial panel. Centralization will accelerate the discovery process and give plaintiffs access to a wider pool of pretrial information.

Give me a good gadget and I’m happy. I think a lot of people in radiology would say the same thing. It’s the reason crowds gathered 15 years ago to see 3D reconstructions revolving aimlessly in space. It’s why MR was a hit in the early 1980s.

Cardiac MR imaging with delayed gadolinium enhancement can detect silent myocardial fibrosis and other cardiac abnormalities in patients with systemic sclerosis, German researchers told attendees of a cardiac session in Vienna.

Whole-body MRI is more sensitive but less specific than FDG-PET/CT for cancer detection, according to researchers from China and Europe. Findings suggest a complementary rather than exclusive role in oncologic imaging for both modalities and validate recent studies suggesting close follow-up since either test can miss metastases.

Marathon runners 50 years or older may face a higher than expected risk of sudden cardiovascular accidents. MR imaging with late gadolinium enhancement may help identify these athletes in time to keep them from potentially deadly episodes, according to German researchers reporting at the 2008 European Congress of Radiology in Vienna.

The relationship between gadolinium-based contrast media for MRI and nephrogenic systemic fibrosis may be more nuanced than previously thought, according to several studies presented Friday at the 2008 ECR.

Radiologists must develop strategies for participating in the new age of imaging-based research. They need to join interdisciplinary teams, develop core imaging facilities for host institutions, involve themselves in small-animal imaging facilities, enter clinical research programs, and learn about PET and molecular imaging, which are at the core of pharmaceutical development.

Delegates caught a glimpse of the future of radiological technology at Sunday’s “ESR meets Israel” session.Israel may be relatively a small nation, with a population of just seven million, but it is making important contributions to innovation. About 900 companies are developing new pharmaceuticals, medical devices, and healthcare IT products. The majority of these businesses are relatively young and are supported by venture capital funding.

Interest in multimodality imaging shows no sign of abating. New tracers are opening up the range of clinical applications, while novel technological solutions are paving the way for yet more modality marriages, according to speakers at Sunday’s special focus session on hybrid imaging.

Days spent sitting in lecture theatres and seminar rooms, long hikes from scientific sessions to the exhibition hall with a briefcase under one arm and a weighty conference bag on the other shoulder, evenings hunched over a laptop putting the final touches to the next day’s presentation… It could be argued that attending ECR is a recipe for backache.

The controversial topic of nephrogenic systemic fibrosis drew a large crowd to a special focus session at the ECR. Delegates queued to quiz speakers about their recommendations for avoidance of the condition, ensuring a lively panel discussion.

Novel concepts and approaches are essential to speed up MRI examinations. Furthermore, pushing speed limits does not just mean doing the same things quicker -- new application areas must also be found.

Cardiac imaging is at a crossroads, according to next year’s ECR president. He’s not alone in holding such an opinion.

Marathon runners 50 years or older may face a higher than expected risk of sudden cardiovascular accidents. MR imaging with late gadolinium enhancement may help identify these athletes in time to keep them from potentially deadly episodes, according to German researchers.

Some tantalizing glimpses into future clinical applications of functional MR and PET imaging were provided at Friday’s New Horizons session.

The relationship between gadolinium-based contrast media for MRI and nephrogenic systemic fibrosis may be more nuanced than previously thought, according to several studies presented Friday at the 2008 ECR.

To the listener, jazz improvisation is an aural flight of fancy, borne aloft by a musician’s on-the-spot skill and imagination. But functional MRI results show the brain actually follows a grounded process of activation and deactivation during these spontaneous musical riffs, according to researchers from the National Institutes of Health and Johns Hopkins University.

A keen sense of anticipation is building up among ECR 08 delegates, as the deadline approaches for the grand opening of the Technical Exhibition on Friday afternoon.
