Modern-day management means accepting changeFour megatrends affect the way we live and work today. These are globalization, technological advancement, the move from production- to service-based industries, and demographic change. Changes caused by these trends will pose challenges, but these challenges can be managed.

Intervention: Needle biopsy, ablation score high in tumorsOver the past 15 years, improvements in biopsy needle design, sampling technique, and expertise of radiologists and cytopathologists have developed in concert with imaging technologies to make percutaneous needle biopsy (PNB) the most common interventional radiologic procedure. With skills refined from performing PNB, radiologists can now use a new and promising outgrowth of this technique-percutaneous tumor ablation-to safely and accurately place needles into a variety of malignant lesions to deliver local treatment.

MR contributes to evaluation of pediatric Crohn's diseaseCrohn's disease can involve any part of the gastroenteric tract but most often affects the distal ileum and colon. It is characterized by chronic inflammation that extends through all layers of the intestinal wall and involves both mesentery and regional lymph nodes.

Sinonasal tumors require team-based approachA variety of neoplasms, derived from a multitude of tissue types, can develop in the sinonasal tract. Sinonasal neoplasms are classified as epithelial or mesenchymal. Epithelial tumors occur in the epithelial lining of the nasal and sinus cavities, accessory salivary tissue, neuroendocrine tissue, and the olfactory mucosa. Mesenchymal tumors are found in supporting tissues.

64-slice scanners build case for coronary CTAResearch focused on the causes, diagnosis, treatment, and prevention of cardiovascular disease is progressing rapidly.1 Radiology has always played a central diagnostic role, particularly in the coronary vessels. A technique for selectively catheterizing the coronary arteries was developed in 1959, and conventional x-ray coronary angiography is still considered the gold standard for detecting coronary artery disease.2

Three-T breast MR imaging moves into clinical arenaBreast MRI has been available for over a decade. It is only now, however, that the examination is becoming recognized as an indispensable adjunct to mammography and ultrasound. Several key factors contribute to this acceptance of clinical breast MRI.

FDG-PET imaging tackles large arteries with atherosclerosisA noninvasive technique to detect vulnerable atherosclerotic plaque is critically needed. Formation of atherosclerotic plaque is a dynamic inflammatory process that involves interactions between atherogenic lipoproteins and macrophages. As vulnerable plaques are usually numerous, extending beyond the culprit plaque and involving multiple vessels, targeting a single plaque underestimates the complexity and extent of disease. Thus, an ideal imaging modality should be able to identify the vulnerable arterial bed and, therefore, the vulnerable patient, to prevent the serious complications of atherosclerosis.

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.

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.
