ContextVision Enters Interventional Radiology Market
BOSTON, Mass. and CHICAGO, Illinois and STOCKHOLM, Sweden – November 30, 2008 – At RSNA today, ContextVision, the software imaging partner for the most recognized medical imaging manufacturers worldwide, will introduce GOPView® iRVPlus, a new image enhancement and dose reduction software package for interventional radiology.
Clinical teams rely on this type of tool during fluoroscopy procedures, such as angioplasty or stent replacement, during which real-time images are used to guide catheters to the target location. GOPView iRVPlus relies on a continuous adaptive filtration method to analyze every pixel in an image, giving every structure in the image the same level of analysis. This rotationally invariant process guarantees that all objects, independent of position and orientation, receive the highest level of image enhancement possible. This eliminates the risk of critical information being overlooked during a procedure, leading to higher clinical value.

Nearly Three-Quarters of Symptomatic Women Are Candidates for Focused Ultrasound Fibroid Therapy: Presented at RSNA
Ed Susman
CHICAGO -- December 1, 2008 -- Approximately 73% of women who present with uterine fibroid symptomatology are eligible candidates for treatment using magnetic resonance imaging (MRI)-guided focused ultrasound (MRgFUS), researchers reported here at the Radiological Society of North America (RSNA) 94th Annual Meeting.
The most frequent reason for disqualification from the procedure was a finding of adenomyosis, a condition that is not amenable to current ablation procedures.
"The ability for physicians to be able to advise patients of their suitability for magnetic resonance focus ultrasound is critical to the success of the procedure," said Suzanne LeBlang, MD, University MRI & Diagnostic Imaging, affiliated with Florida Atlantic University, Boca Raton, Florida.

New Model Developed to Estimate Radiation Skin Doses during CT Guided Interventional Procedures
A new model that would allow interventional radiologists (radiologists who specialize in fine needle aspiration, fine needle biopsy and radiofrequency ablation) to better estimate patient radiation skin doses during CT guided interventional procedures has been developed according to a study performed at the Agios Savvas and Konstantopoulio Hospitals in Athens, Greece.
“It is clear that skin doses in CT guided interventional procedures can become very high. Even for skin doses around 1 Gy, the prospect of repeating a procedure makes the determination of peak skin dose crucial for avoiding radiation injuries,” said Ioannis A. Tsalafoutas, PhD, Virginia Tsapaki, PhD, Charikleia Triantopoulou, MD, John Papailiou MD, Christina Pouli, MD, Virginia Kouridou, MSc, and Ioanna Fagadaki, MD, authors of the study.
The theoretical model that was developed “considers the skin dose resulting from each CT slice, utilizing data that is already stored along with CT images. The skin doses calculated with this model were compared with those measured using films positioned under patients that underwent CT guided interventional procedures.

Core Needle Breast Biopsy Safe for Patients Taking Blood Thinners
It is safe to take anticoagulants (blood thinners) before core needle breast biopsies, according to a study performed at the Elizabeth Wende Breast Clinic in Rochester, NY. Core needle biopsies are offered as an alternative to surgical biopsy when a tissue sample of an irregular area in the breast is found by mammogram or sonogram. “They are safer than surgical procedures, require fewer anesthetics, and are accurate,” according to Patricia Somerville, MD, lead author of the study.
The study included 200 women who were taking anticoagulants (blood thinners) and 855 women who were not. Adverse reactions, lumps and bruises, after a woman’s core needle biopsy were recorded. Results showed that lumps or bruising occurred in 34% of women who were taking blood thinners and 26.5% of women who were not taking them.

Endoscopic ultrasound can offer safer and more effective cancer therapy
Washington, September 13 (ANI): American scientists are studying the efficacy of a therapeutic technique that can allow doctors to directly inject tumours with cancer fighting agents from inside the body.
The technique called curvilinear EUS uses a flexible gastrointestinal endoscope with a miniature ultrasound transducer on the tip to guide a small needle directly into a tumour.
Dr. Robert Hawes, Professor of Medicine and Peter Cotton Chair for Endoscopic Innovation at the Medical University of South Carolina, says that the new technique can prove to be a safer and more effective approach to administering chemotherapy, as it allows doctors to deliver therapy right to the tumour and avoid damaging normal surrounding tissues.

Stent Grafts: A Better Way To Treat Blunt Trauma Injuries
Endovascular repair-fixing an injury in a blood vessel from inside that vessel-is a better option for individuals who receive highly lethal injuries from high-speed collisions or falls (together referred to as blunt trauma) and is shown to save more lives and nearly eliminate paraplegia (the loss of the ability to move and/or feel both legs), a complication of surgical repair for thoracic aortic aneurysms.
"Analysis of the available data provides unequivocal support for endovascular repair to replace open surgery as the procedure of choice for repair of the most common traumatic aortic injury," said Eric K. Hoffer, the director of vascular and interventional radiology at Dartmouth Medical School. "This minimally invasive interventional radiology technique can decrease the death rate by half and diminish the risk of paraplegia by 75 percent as compared to open surgical repair," he added.

Foam For Varicose Veins Found To Be Safe In Preliminary Results From Phase 2 Trial
A small group of patients with a common heart defect who were treated for varicose veins with an injectable microfoam experienced no neurological, visual or cardiac changes as a result of the treatment, according to preliminary results from a phase II trial. The results were presented in Washington, D.C., at the annual scientific meeting of the Society of Interventional Radiology (SIR).
Injectable foams are usually made by mixing a sclerosant, an irritant that causes damage to the vein wall and subsequent scarring, with room air. Sclerosant foams have been a standard treatment since 1997 for spider veins and small varicose veins. Varisolve®, a foam made with carbon dioxide, is relatively painless compared to other sclerosants, which can cause burning, said John D.

Treatment Gives Lung Cancer Patients With Inoperable Tumors Two Years Or More
Radiofrequency ablation (RFA) -- an interventional treatment that "cooks" and kills lung cancer tumors with heat -- greatly improves survival time from primary or metastatic inoperable lung tumors, according to a study released at the Society of Interventional Radiology's 33rd Annual Scientific Meeting. Of the 244 patients suffering from lung metastases (195 patients) or primary non-small cell lung cancer (49 patients), 70 percent were still alive at two years, including 72 percent for lung metastases and 64 percent for primary lung cancer.
These survival results are similar to surgical results from other studies, but the interventional treatment is less invasive and has far fewer side effects and less recovery time. The researchers found that RFA often can completely destroy the primary tumor and, therefore, extend a patient's survival and greatly improve his or her quality of life. Survival thus becomes dependent on the extent of disease elsewhere in the body.

New Interventional Radiology Treatment Shows Hope for People With Complications from Bone Marrow, Stem Cell Tranplants
Newswise — The standard treatment to treat graft-versus-host disease (GVHD) after bone marrow or cord blood transplant is intravenous (IV) steroids that alter the immune response; however, it is not always effective and failure results in very high mortality. In a study released today, 15 patients who failed standard treatment were given a high dose of steroids directly to the affected organ. By delivering the steroids via catheter to the arteries that are supplying the organs affected by GVHD, a much higher, more effective dose can be given because the rest of the body is spared from the steroid’s side effects.
“Overall, fewer than 30 percent of patients with steroid-resistant GVHD respond completely or partially to the standard IV treatment, and their chance of living one year is 15 percent or less. This interventional radiology treatment can be life-saving for these people,” said Joshua L. Weintraub, M.D., chief of the Division of Vascular and Interventional Radiology at Mount Sinai Medical Center in New York City.

Breakthrough Treatment For Severe Frostbite Saves Limbs
Using imaging to visualize areas lacking blood flow and deliver drugs via catheter, interventional radiologists are reopening recently frozen, clotted arteries with clot-busting and anti-spasmodic drugs. The people in a recent prospective trial had severely frostbitten hands and feet (with tissue frozen to the bone and damage occurring deep in muscles, tendons, nerves and blood vessels). Typically this leads to gangrene and loss of limbs. In severe frostbite, the blood vessels are affected and blood flow is blocked. After thawing and re-warming, small clots form. Spasm of the injured arteries further impedes flow to the smallest vessels of the limbs.
The standard treatment for frostbite -- typically involving re-warming the affected area and, in severe cases, amputation -- hasn't changed for decades. Interventional radiologists used angiography, an X-ray exam of the arteries and veins, to confirm loss of blood flow to a patients hand or toes, then intra-arterial catheters to directly deliver drugs to dissolve the blood clots and relax the arteries' muscular walls. This treatment was significantly successful in preventing amputation and saving limbs, according to a study released at the Society of Interventional Radiology's 33rd Annual Scientific Meeting.
