New ACR MR Safety Guidelines
According to new American College of Radiology (ACR) guidelines
published in the June issue of the American Journal of
Roentgenology, restricting MR machine access and improving
education would help reduce the number of accidents that occur
during MR examinations.
Created partly in response to the 2001 death of a New York child
who was killed when an oxygen tank was pulled into an MR gantry,
the guidelines are the work of an ACR panel chaired by Emmanuel
Kanal, MD. The report was prepared under the guidance of a special
ACR task force on safety, chaired by James P. Borgstede, MD.
The document, according to the panel, "is intended to be used as
a template for MR facilities to follow in the development of an MR
safety program."
The new MR Safe Practice Guidelines address topics including:
static magnetic field-related issues such as translational and
rotational forces on ferromagnetic materials; time varying magnetic
field-related issues such as induced voltage, auditory
considerations, and thermal issues; personnel qualifications and
training; site access restrictions; pregnancy-related issues;
contrast agent safety; and claustrophobia, anxiety, sedation,
analgesia, and anesthesia.

Patient Web Site Recognized
RadiologyInfo.org, a Web site for radiology patients that is
jointly produced by the ACR and the Radiological Society of North
America (RSNA), has received an award from the American Society of
Association Executives. The award recognizes associations that
produce programs in citizenship and community service, business and
social innovation, knowledge creation, education, skills training,
and standard setting.
The site, which was launched this spring, features extensive
information on diagnostic radiology, radiation therapy, and
interventional radiology. It explains how procedures are performed
and what patients can expect during those procedures, and also
offers a glossary of terms.
Pettigrew Named NIBIB Director
Roderic I. Pettigrew, MD, PhD, has been appointed the first
director of the National Institutes of Health's National Institute
of Biomedical Imaging and Bioengineering (NIBIB). Pettigrew is
currently the director of the Emory Center for MR Research at Emory
University School of Medicine, Atlanta, and is expected to begin
his appointment in late August or early September. He is known for
his work in dynamic three-dimensional cardiac MRI at Emory.
NIBIB was founded on December 29, 2000, as part of the NIBIB
Establishment Act signed into law by then-president Clinton. The
organization's budget for 2002 is $112,022,000, while the budget
for 2003 is $121,378,000.
According to the NIBIB Web site, its mission is "to improve
health by promoting fundamental discoveries, design, development
and translation, and assessment of technological capabilities in
biomedical imaging/bioengineering." The organization plans,
conducts, and supports an integrated program of research and
research training.
Contrast-Enhanced Breast MRI
A new study published in the June issue of the British Journal
of Surgery suggests that dynamic contrast-enhanced MR imaging
(DCE-MRI) improves the surgical management of invasive lobular
breast cancer.
The study, which included data from 21 women with infiltrating
lobular carcinoma (ILC), compared the effectiveness of mammography
and ultrasound against DCE-MRI. The results showed that DCE-MRI was
more effective in evaluating ILC in the breast.
The study, conducted jointly by the academic surgical unit at
Castle Hill Hospital, Hull, and the Centre for MR Investigations,
Hull Royal Infirmary, United Kingdom, concluded that DCE-MRI is
more accurate than conventional imaging in terms of delineating
multifocal disease.
GAO Releases Mammography Access Data
The General Accounting Office (GAO) has issued a report on the
nation's ability to provide timely mammography services. The
report, "Mammography: Capacity Generally Exists to Deliver
Services," concludes that there is sufficient equipment to handle
the demand for mammography services, though there are certain areas
of the country where women must still wait for up to 3 months to
receive services, such as the Baltimore metropolitan area.
In addition, Houston and Los AngelesĀ officials report that
large patient loads at public health facilities that serve
low-income women lead to long waits, while no delays existed at
other facilities. However, women who needed follow-up mammograms
were able to get appointments at other facilities.
A 15% increase in the use of mammography services between 1998
and 2000, as measured by the number of mammograms provided to women
40 and older, was also reported.
However, the GAO cautions that there is the potential for
reduced access in relation to the growing shortage of personnel
able to perform and interpret mammography services. Report data
were collected only through October 2001, and does not factor in
the continuing downturn in the number of mammography facilities.
Since October 2001, 118 facilities have been closed, according to
American College of Radiology statistics.
