Multislice SPECT/CT gains wider clinical acceptanceMultimodality imaging is rapidly becoming an essential tool, particularly in oncology, where many publications have focused on a role for PET/CT.

SPECT/CT dramatically cuts radiation dose in some breast cancer patientsDose reduction at one time played second fiddle to image quality, but today it enjoys top billing. New algorithms are coming into play in CT, radiography, and fluoroscopy to maintain image quality at traditional levels by processing out the noise that sneaks in during low-dose exams. In some cases, fear of radiation has gotten so bad that patients forego CT and other sources of ionizing radiation all together.

PACS focus shifts from radiology to the enterprisePACS already enjoys success in the healthcare marketplace and provides numerous benefits to institutions where it has been implemented. Now the focus is shifting from departmental to enterprise-wide systems. The enterprise is a different place, more intimidating than the safe confines of a radiology department. An enterprise network makes its way to many more locations; in some cases, to every location. Users are everywhere. Some have valid reasons to access imaging information, and others do not.

PET/CT need not become a medical battlegroundThe number of PET/CT systems in Europe is limited but growing rapidly. The world market was estimated at around $1.2 billion in 2004, which translates into 600 to 700 systems sold. Approxi-mately 90% of European PET sales, whether new installations or replacement, now involve PET/CT scanners. This figure shows the tremendous need for education in PET/CT.

Animal imaging emerges onto the research agendaData collected by the European Association of Radiology in 2005 revealed that more than 60 centers in Europe have facilities for animal imaging research. Of these, 12 are in Germany, 10 in France, six in the U.K., and five each in the Netherlands and Belgium.

PACS images can be treated byte by byteOur PACS project at the University Hospitals Leuven in Belgium radically follows from an overall IT perspective. The emphasis on image flow throughout the entire hospital supersedes operations within the image-generating departments. Image management outside the radiology department is not an afterthought, but rather an integral part in, and even a driving factor for, decisions that the department makes. Although images have specific characteristics and requirements, we often consider them yet another type of data or a collection of bytes.

The ISR presidential pen writes, and having writ, moves onAfter 12 years on the board of the International Society of Radiology (ISR), it is with complex feelings I have entered the last stage as the organization’s immediate past president. On one hand, it is relaxing to know that new and powerful forces have taken over. On the other, it is a little bit sad to know that there was a lot left to do, issues that I should have fixed-or at least tackled to start a resolving process.

MRI proves clinical value in lung cancerNon-small cell lung cancer is the leading cause of cancer-related deaths in women and men in the Western Hemisphere. Surgical resection remains the mainstay of therapy in disease at stages I and II, and this treatment has an acceptable morbidity and mortality rate. Imaging is needed for effective treatment planning and accurate diagnosis, including preoperative assessment of resectability.

Varicose veins may be setting of next turf warIt's quick, safe, and relatively painless, and if interventional radiologists want to own it, they'd better step up quickly: Endovenous laser treatment of varicose veins is poised to take off, according to researchers at Cornell University. A two-year follow-up of 97 treated limbs showed a 6% recurrence rate, compared with 10% or higher recurrence that was reported for surgery, radio-frequency ablation, and transcatheter sclerotherapy.

Techs need advanced postprocessing skillsPostprocessing software vendors sell their software based on the "push of a button" fantasy: Simply by pressing several buttons, the user completes the entire case. Although software interfaces are becoming increasingly more user-friendly, postprocessing volumetric data still requires an advanced skill set.
