Prostate imaging goals shift as therapeutic options expandMany of the emerging imaging modalities for prostate cancer were first developed for breast cancer patients and then adapted to the prostate. Clearly, almost all aspects of prostate cancer care and diagnosis lag behind those of breast cancer. Breast cancer researchers have successfully carried out a number of groundbreaking randomized controlled trials to define the best treatment approaches, but prostate cancer has yet to see a successful trial comparing even the major forms of prostate cancer treatment: radical prostatectomy and radiation therapy. Adding to the frustration that prostate patients face when no one can tell them the best approach for treating their cancer, two new primary therapies have been sanctioned by the American Urologic Association: cryotherapy and watchful waiting.

Cardiology PACS basics: With large studies and growing volume, cardiology can benefit from PACSPACS are electronic medical image management systems. They consist of image display systems, archiving systems, networks, and interfaces, presenting one unified system to the user. They have been in development since 1982 and have predominantly been used in radiology, transforming manual film operations to a filmless environment. Radiology PACS has evolved from an emerging technology to a mature, billion dollar North American market.

CT spurs concern over thyroid cancerA truism about any rapidly adopted technology, no matter what its specifics, is that the benefits are readily apparent soon after its introduction, and the untoward effects are inevitable but delayed. The initial wave of enthusiasm about a new test or a new technique's virtues drowns out, at least for a while, any discussion about its putative ill effects. This truism is especially apparent when the innovation inspires a metamorphosis in practice and perception that alters the allocation of resources, the focus of training, and the nature of work.

MR finds widespread clinical use in MS diagnosis, managementMR imaging has provided important insights into the pathophysiology of multiple sclerosis.1 Conventional MR scans afford only gross estimates of the extent and nature of tissue damage associated with MS,2 however, and the data correlate poorly with measures of concurrent disability in patients. Advances in MRI technology have improved the correlation of its findings with clinical status and increased the utility of MRI data as surrogate markers in monitoring disease progression and response to therapy.3 Newer techniques, such as magnetization transfer (MT), diffusion-weighted, and functional MRI, as well as proton MR spectroscopy and measures of brain and spinal cord atrophy, may help further elucidate MS pathology2 and provide opportunities for new treatment approaches.4

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.

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

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.
