SCIENCE TO PRACTICE:

S. Nahum Goldberg: Can Tumor Growth Be Further Inhibited by Combining Drugs Such as Bortezomib with Image-guided Interventional Oncologic Procedures?
Although Poff et al were able to demonstrate delayed tumor growth of murine squamous cell carcinoma in an orthotopic C3H murine tumor model when adding pulsed high-intensity focused ultrasound as an adjunctive pretreatment to Bortezomib, further study of this combined therapy paradigm is needed.

Controversies:

C. Douglas Maynard: Radiologists: Physicians or Expert Image Interpreters?
Are we going to be physician radiologists, or are we going to be content with reading high-resolution images off the beaten path of health care?

William G. Bradley, Jr: Off-site Teleradiology: The Pros
While I agree with Dr Maynard that off-site teleradiology is going to lead to commoditization, I would argue that commoditization started many years ago and that this is just another step in the progression.

Perspectives:

Daniel C. Sullivan: Imaging as a Quantitative Science
This new era of health care carries with it three imperatives for radiology: Clinical imaging must increasingly provide (a) biochemical information that is (b) as quantitative as reasonably achievable and information that is (c) relevant to the therapeutic options available to the treating physicians.

Imaging of the isovolumic contraction and relaxation phases of the cardiac cycle is feasible with cine MR imaging by using high frame rates through echo sharing and parallel acquisition; these MR-derived indexes may serve as surrogates for cardiac systolic function in the theoretic load-independent phases and can help distinguish between normal and severe systolic cardiac dysfunction.

High-spatial-resolution contrast-enhanced MR angiography of the entire lower extremity arterial tree at 3.0 T can be performed with a contrast agent dose at least as low as 0.1 mmol/kg, without compromising image quality, as compared with 0.2 mmol/kg and 0.3 mmol/kg.

SIGNS IN IMAGING:

Kok Chye Tan: Enlargement of the Hilar Periportal Space
Enlargement of the hilar periportal space on MR images is a useful sign for identifying early cirrhotic livers in patients without other conventional findings of cirrhosis, thus allowing early intervention and prompt disease management.

Ana M. Ferreira, Ana Vaz, Morgado Viana, Paulo Gil-Agostinho, and Filipe Caseiro-Alves: Case 136: Intraductal Papillary Mucinous Tumor (Main Duct Type) of the Pancreas
Imaging of intraductal papillary mucinous tumors is important not only to identify the tumor but also to determine the appropriate treatment strategy in relation to the site and size of the lesion.
