Automated breast volume sonography improves screening and diagnosis of breast cancer for Asian women
2012-04-30
(Press-News.org) A new study from researchers at the Bangkok Breast Center shows significant improvement in the detection of breast cancer in Asian women using automated breast volume sonography (ABVS) as compared to hand-held ultrasound (HHUS).
In their study on 504 findings in 212 patients at the Bangkok Breast Center, researchers found that ABVS agreed with HHUS in detecting 15 suspicious lesions, uncovered 12 additional suspicious lesions, and excluded 3 suspicious lesions in these cases. A coordinating five-year retrospective study on 26,741 mammograms with ultrasound also revealed that ultrasound helped identify 141 new breast cancers in mammographically negative cases.
Dr. Wilaiporn Bhothisuwan, lead author for this study, said "Although there have been improvements from dedicated mammography to digital mammography, we still have limitations because 75% of our Thai breasts are mammography difficult breasts. ABVS has helped us overcome some of the known technical limitations of US, which include a limited field of view (FOV) and scans that require high skill, experience, and time. With ABVS, the FOV is large enough to cover most of Asian breasts."
With the advances of ABVS, Dr. Bhothisuwan and her co-author Ms. Pramaporn Kimhamanon saw immediate improvements in the quality of their images. She added, "The images from this scan come in multi-slices and multi-planes and can be displayed, manipulated, archived, and restored in the same way as CT volume scan. This helps solve the problem of operator dependency and gives more reproducible and standardized imaging."
The study will be presented at the 2012 ARRS Annual Meeting in Vancouver, Canada.

About ARRS
The American Roentgen Ray Society (ARRS) was founded in 1900 and is the oldest radiology society in the United States. Its monthly journal, the American Journal of Roentgenology, began publication in 1906. Radiologists from all over the world attend the ARRS Annual Meeting to take part in instructional courses, scientific paper presentations and scientific and commercial exhibits related to the field of radiology. The Society is named after the first Nobel Laureate in Physics, Wilhelm Röentgen, who discovered the X-ray in 1895.

As skiing and snowboarding continue to be the most popular winter sports, they also carry a significant risk of injury. One new exhibit will show how radiologists can meet these injuries head on with proper patient management and the latest imaging techniques.
"It is important for radiologists to understand these injuries patterns," said Dr. Hillary Boortz, lead author for this exhibit. "When a patient presents with the appropriate history, the radiologist can properly protocol the study and alter their search algorithms to assure that an injury isn't overlooked." She ...

As more patients are referred to tertiary care center with previous images, a new study from researchers at the Westchester Medical Center shows how radiologists are tackling the challenges of interpreting outside studies and reviewing discordance opinions.
"Outside studies were becoming a problem in our institution," said Dr. Zvi Lefkovitz, co-lead for this study. "We were receiving a lot of disjointed, fly-by-night examinations, and we had no formalized policy for reviewing these exams." Lefkovitz and his team began a comprehensive process of overhauling their procedures, ...

Shoulder injuries are among the most frequently encountered musculoskeletal injuries treated in emergency departments. One new study shows how radiologists can more effectively identify these injuries and improve patient outcomes.
"The severity of shoulder injuries are often underestimated," said Dr. Scott Sheehan, lead author for the study. "Subtle injuries can have significant consequences if not recognized and treated promptly." Sheehan and his co-authors began studying the effects of traumatic shoulder injuries after one of his radiology mentors suffered a shoulder ...

A new study from UCLA shows how magnetic resonance angiography (MRA) and computed tomography angiography (CTA) are equivalent in delineating anatomy in living renal donors.
In a study that examined 30 patients and 60 kidneys, both modalities were "excellent" in detecting the number of renal arteries and veins. Dr. Mittul Gulati, lead author for the study noted, "either MRA or CTA are great tools for helping surgeons remove kidneys safely, identifying donor and recipient veins and vessels, and identifying incidental findings."
The results could potentially reduce radiation ...

With the increase of obesity in the last 50 years, bariatric surgeries are becoming a common solution for tackling this epidemic. A new exhibit shows how radiologists play a key role in ensuring the success of these procedures.
"Although complications are generally rare with Roux-en-Y gastric bypass and gastric banding procedures, it's critical for radiologists to be familiar with both the normal presentations and possible complications for these surgeries," said Dr. Mariam Moshiri, lead author for this presentation.
Dr. Moshiri and her co-authors at the University ...

BOSTON – More than 1 million youths ages 15-24 have sexually transmitted infections (STIs) caused by Chlamydia trachomatis and Neisseria gonorrhea. Many others, however, are unaware they are infected because they have not been tested.
Technology can change that, according to preliminary data from a study to be presented Saturday, April 28, at the Pediatric ...

BOSTON – Although children are more likely than adults to suffer from many diseases, few clinical trials are being conducted to test drugs in pediatric patients, according to a study to be presented Saturday, April 28, at the Pediatric Academic Societies (PAS) annual meeting in Boston.
Drug studies in children are important because children often respond differently to medications than adults. However, there is widespread concern about the lack of clinical evidence available to guide physicians in prescribing pharmaceuticals to children.

BOSTON – Contrary to what many trauma teams believe, the presence of family members does not impede the care of injured children in the emergency department, according to a study to be presented Saturday, April 28, at the Pediatric Academic Societies (PAS) annual meeting in Boston.
Professional medical societies, including the American Academy of Pediatrics and the American College of Emergency Physicians, support family presence during resuscitations and invasive procedures. The degree of family member involvement ranges from observation to participation, depending ...

BOSTON – Black children are less likely than white children to receive medication for abdominal pain in the emergency department (ED) even when they report severe pain, according to a study to be presented Saturday, April 28, at the Pediatric Academic Societies (PAS) annual meeting in Boston.
"The emergency department serves as our nation's health care safety net, where all children can receive care regardless of their insurance status, ability to pay or race," said lead author Tiffani J. Johnson, MD, pediatric emergency medicine fellow at Children's Hospital of Pittsburgh ...

BOSTON – While eating too much food can cause obesity, the fear of not having enough food may lead to the same result, according to a study to be presented Saturday, April 28, at the Pediatric Academic Societies (PAS) annual meeting in Boston.
Being worried about not having enough food to feed one's family, a situation called food insecurity, is common in low-income families. These families often are overweight, too.
"Understanding the reasons why poverty puts families at greater risk of obesity is essential to addressing the epidemic," said study lead author Rachel ...
