MR Tumor Staging for Treatment Decision in Case of Wilms Tumor

Nephroblastoma – also known as Wilms tumor – is the most frequent renal malignancy in childhood with the highest incidence of this tumor within the fourth year of life. 80% of patients are less than 5 years old, however it is a rare condition in neonates ([...]

Advantages of MSK Imaging at 3 Tesla with special focus on Spine and Tumor Imaging.

The clinical advantages of upgrading to higher field strength (3T) magnets, improving coil technology, and using larger bore-sizes are proving to be significant. Through 10 case studies, it is suggested that the use of 3T open bore system with TrueForm technology can improve the diagnostic potential, as well as widen the indications, of MRI. The cases illustrate advantages of musculoskeletal imaging with a special focus on spine and tumor imaging. [...]

How Breast MRI Changed the Operative Management

MR diffusion-weighted imaging (DWI) is no longer just for brain applications. Whole body DWI is becoming a standard application in routine imaging. Whole body DWI has become as valuable as T2 contrast in tumor imaging and it allows characterization of tissue properties. This article provides responses to some of the more frequently asked questions including the background, application, and interpretation of whole body DWI and its calculated Apparent Diffusion Coefficient (ADC) images.
