Contrast gives the edge to digital breast scansThe clinical importance of tumor angiogenesis in primary breast cancer is well known. Studies have shown that intratumoral microvessel density is an independent prognostic indicator that correlates with a higher incidence of metastases.1,2

Lung ablation shows promising results in safety and efficacyLung carcinoma remains the leading cause of cancer death in the U.S. Over the past decade, lung cancer death rates have more than quadrupled, from 5.4 to 29.4 per 100,000.1 The American Cancer Society estimates that in 2005 the number of lung cancer deaths will rise to 163,510-90,490 men and 73,020 women-accounting for 28% of all cancer-related deaths. The number of newly diagnosed lung cancers will rise to 172,570, or 93,010 new cases in men and 79,560 in women.2 Nearly 60% of those diagnosed with lung cancer die within one year of their diagnosis and nearly 75% within two years.2

MR, CT imaging offer answers to questions about renal massThe widespread use of cross-sectional imaging techniques means that renal masses are now a common incidental finding. The term renal mass covers a diverse group of pathologic entities, including inflammatory, vascular, and benign tumors and neoplastic lesions. Most renal masses are simple cysts that can be characterized easily and require no treatment or follow-up. But approximately 25% to 40% of all renal cell carcinomas are diagnosed after the unexpected discovery of a renal mass.1 Around 85% of these renal cancers will be adenocarcinomas. Most of the others will be transitional cell carcinomas of the renal pelvis.

MSCT provides first- line colon assessmentColorectal carcinoma is believed to be the third most common malignancy and the third leading cause of cancer-related deaths for men and women in Western countries. It is curable if detected at an early stage and preventable if precursor adenomatous polyps are detected and removed promptly.

Carotid stenting offers new interventional practice optionAs carotid artery stenting becomes an accepted tool for stroke prevention in appropriate patients, interventional radiologists and neuroradiologists are determining where this procedure fits into their practice. Some have already developed an active carotid artery stenting practice, but others are looking for resources to help them begin to offer this service. Consideration of many elements is required to offer a high-quality service.

Kidney tumor ablation treats nonsurgical candidatesOver 35,000 new cases of renal cell carcinoma occurred in the U.S. in 2001,1 most of them detected as incidental imaging findings on CT, MR, or ultrasound.2,3 Since most of these tumors are relatively small when detected, the classic clinical triad of flank pain, hematuria, and palpable mass is now rarely encountered. Many of these incidentally discovered RCCs are also slow growing. Bosniak et al showed that RCCs smaller than or equal to 3.5 cm grow at an average rate of 0 to 1.1 cm/year (mean 0.36 cm/year).4

Analysis teases out true value of outsourcing anytime readsThe need for nighttime coverage relief was the initial driver of commercially viable teleradiology. For several years, however, the local in-house radiology group gained no economic value for outsourcing its nighttime work, because its members had to reread the cases the next day to formally convert the reports to primary reads. The group also had to pay a premium for nighttime services.
