Dr. Gerry Rivera co-authors Interventional Radiology Book in Spanish!

September 16, 2014

Dr. Rivera-Sanfeliz, a Clinical Professor of Radiology and member of our Division of Vascular and Interventional Radiology, has co-authored an Interventional Radiology book written in the Spanish language in collaboration with Cuban Radiologists from Hospital Hermanos Ameijeiras in Havana, Cuba. The completion of this book is the result of years of close collaboration between Dr. Rivera-Sanfeliz and his fellow Cuban colleagues.

Dr. David Karow and Anders Dale, PhD revolutionize prostate cancer diagnosis with MR Technology

August 12, 2014

MRI technology was used to identify and locate a probably tumor (outlined in yellow) during a targeted prostate biopsy for a patient who had previously had multiple negative biopsies but had persistently high PSA levels. Resulting biospy confirmed presence of high-grade cancer. [read more]

UCSD Radiology Masters PROMO Imaging

August 19, 2014

PROMO is a revolutionary prospective motion-artifact reducing MRI technique developed by Anders Dale and his team. It works by monitoring head position every second or so and adjusting the gradients so the head is always centered relative to the gradients.

UCSD Radiology uses RSI Imaging to Hunt Down the Extent of Tumors

August 20, 2014

Restriction Spectrum Imaging (RSI), an advanced diffusion-weighted imaging technique developed at the Multimodal Imaging Laboratory by Dr. Anders Dale and Dr. Nathan White, overcomes many of the known limitations of standard DWI by separating different components of the diffusion signal, allowing one to disambiguate the slow (restricted) diffusion associated with tumor cellularity and axons from the fast (hindered) diffusion that is often influenced by edema and other non-tumor tissue in the extracellular matrix.

Isolating this slow, restricted diffusion component with RSI can significantly 1) improve tumor conspicuity in patients with high-grade primary and metastatic brain tumors, 2) improve fiber tracking through regions of peritumoral edema and 3) facilitate the interpretation of tumor response on imaging following treatment with antiangiogenic agents, compared to standard DWI and DTI.

Dr. David Karow, working with Dr. Dale, has developed RSI techniques for the evaluation of prostate cancer, providing the urologists with the first-ever ability to perform image-guided MR biopsies of the prostate, directly targeting the areas worrisome for prostate cancer.
