Rising service costs prompt hospitals to examine new options
May 6, 2010 -- Cash-strapped hospital administrators are turning to in-house solutions with help from original equipment manufacturers to keep their imaging equipment in good working order, according to a new survey of the diagnostic imaging equipment service industry.
Preoperative MRI preserves erectile function after RALP
May 6, 2010 -- Preoperative prostate MRI can help urologic surgeons spare the neurovascular bundle during robotic-assisted laparoscopic prostatectomy (RALP) in treating prostate cancer, according to a study presented at the American Roentgen Ray Society meeting this week in San Diego.
VC shows high diagnostic yield after failed colonoscopy
May 6, 2010 -- Virtual colonoscopy finds significant pathology in patients referred after failed colonoscopy, according to a study presented at the Digestive Disease Week meeting in New Orleans. The results show the need for a complete colon exam and highlight VC's strengths in detecting extracolonic abnormalities.
More frequent follow-up helps breast conservation patients
May 5, 2010 -- SAN DIEGO - Women treated with breast conservation therapy may do better with mammography follow-up twice a year rather than annual surveillance, according to research presented at this week's American Roentgen Ray Society meeting.
FDG-PET/CT detects recurrence of colorectal cancer
May 5, 2010 -- FDG-PET/CT has a "significant role" in characterizing suspected colorectal cancer recurrence at an early stage, according to a study presented by U.K. researchers at the American Roentgen Ray Society meeting this week in San Diego.
Researchers eye dual-energy DR as calcium-scoring option
May 5, 2010 -- Could digital radiography (DR) become an alternative to CT for coronary artery calcium scoring? Some U.S. researchers think so -- they've developed a DR-based dual-energy subtraction algorithm that with further refinement could provide calcium scores at a lower cost and radiation dose than CT.
GAO numbers overstate growth in medical imaging
May 4, 2010 -- SAN DIEGO - Imaging growth in the U.S. hasn't risen nearly as dramatically as the government says it has; in fact, it's been pretty flat, according to researchers who presented a study on the topic on Monday at the American Roentgen Ray Society meeting.
HDCT with ASIR recon sharpens low-dose abdominal images
May 4, 2010 -- High-definition CT (HDCT) combined with adaptive statistical iterative reconstruction (ASIR) is a good way to diagnose abdominal conditions at very low radiation doses, according to researchers from Hong Kong.
Flexible sigmoidoscopy of dubious value after VC
May 4, 2010 -- The yield of additional pathological findings was quite low in a group of symptomatic patients who underwent flexible sigmoidoscopy after virtual colonoscopy screening, according to a poster presentation at this week's Digestive Disease Week meeting in New Orleans.
Young adults face higher CT radiation risk than seniors
May 4, 2010 -- Age has a lot to do with the estimated radiation risk of developing cancer as a result of having an abdominal or pelvic CT scan. Senior citizens have half the risk of young adults, a research team told attendees at the American Roentgen Ray Society annual meeting being held in San Diego this week.
Radiologists may be prone to work-related injuries
May 3, 2010 -- Thanks to a lack of attention paid to developing comfortable and ergonomic work spaces, radiologists appear susceptible to work-related musculoskeletal symptoms, according to research presented Monday at the American Roentgen Ray Society meeting in San Diego.
Breast MRI improves cancer staging for newly diagnosed women
May 3, 2010 -- Contrast-enhanced breast MRI finds breast lesions missed on mammography and ultrasound, and can help surgeons plan the best surgical treatment, improving patient outcomes, according to a study presented at the American Roentgen Ray Society meeting this week in San Diego.
Valkyrie software rides to rescue of CT radiation dose dilemma
May 3, 2010 -- An automated software algorithm called Valkyrie that extracts radiation dose information from CT exams and tracks it automatically may help imaging sites better follow patient radiation exposure and avoid overdoses, according to a study presented this week at the American Roentgen Ray Society meeting in San Diego.
