Radiological Society of North America meeting abstracts.
1. Having an annual MRI or ultrasound in addition to mammography is beneficial for women with dense breasts who are at an elevated risk for breast cancer. In a large multicenter trial, these more sensitive technologies increased cancer detection in this group (Wendie A. Berg, MD, PhD, of Johns Hopkins University)
2. Decompressing a herniated disc via a minimally invasive needle procedure may keep pain at bay longer than standard treatment with medication and physiotherapy. Patients who had percutaneous disc decompression had significantly lower (P=0.01) pain scores after two years than did patients who were managed conservatively (Dr Alexios Kelekis, of the University of Athens in Greece).
3. Using ultrasound to examine lumps and suspicious areas of the breast may be an effective alternative to biopsy for women under 40. In two analyses, targeted ultrasound correctly distinguished between cancerous and benign lesions in the majority of cases (Constance Lehman, MD, of the University of Washington)
4. Radiologists here have rejected revised mammography guidelines from the U.S. Preventive Services Task Force (USPSTF), arguing that they are not backed by scientific evidence and will lead to unnecessary deaths. Under the revised guidelines, screening will begin too late and its effects will be too little, said Dr Stephen A. Feig, of the University of California Irvine and president elect of the American Society of Breast Disease. We will save money but lose lives.
5. A fifth of patients who have narrowing of the leg arteries also have narrowing of the arteries in the heart, but they don't know it. In a randomized controlled trial in the Netherlands, 19% of patients with peripheral arterial disease also had coronary artery disease. (Dr Rozemarijn Vliegenthart Proenca, of the University Medical Center Groningen in the Netherlands).
6. Some women already at high risk of breast cancer should be cautious about having mammography or chest x rays before the age of 30 because the imaging may increase the risk of developing the disease. Five or more x rays, or any exposure to ionizing radiation before age 20, increased the likelihood of breast cancer two and a half times in this high risk group (Marijke C. Jansen van der Weide, PhD, of the University Medical Center Groningen in the Netherlands).
7. More than half of patients who have abdominal computed tomography (CT) scans may be getting extra series of tests that aren't necessary and that lead to increased radiation exposure. In a retrospective analysis, 52.2% of patients had an unindicated series of scans most often delayed phase imaging, which involves a contrast agent diffusing through blood, tissues, and subsequently organs. (Dr Kristie Guite, of the University of Wisconsin in Madison).
8. Adding elastography to breast ultrasound may help distinguish between cancerous and benign results, potentially decreasing the need for biopsies. The imaging test, which looks at the stiffness of tissue, correctly identified 98% of cancerous lesions and 78% of those that weren't cancerous in a trial of about 200 patients. ( Dr Stamatia V. Destounis of Elizabeth Wende Breast Care in Rochester)
9. Pop top tabs are supposed to stay on soda cans, but they may still end up in children's stomachs. So called stay tabs were introduced in the 1970s as an alternative to pop tops that completely severed from aluminum cans. But researchers at the Radiological Society of North America meeting say the prevalence of swallowed stay tabs may be more common than previously thought because they're harder to spot on radiographs than other objects that kids ingest such as pennies.
10. For years, the pager and cell phone have summoned on call radiologists to the emergency room. Now this leap in technology: an iPhone App that lets radiologists diagnose a patient remotely, wherever they may be. Using an iPhone application radiologists made correct diagnoses of appendicitis in 124 of 125 computed tomography (CT) scans. (Dr Asim Choudhri, of Johns Hopkins University in Baltimore).

Funny clinical notes (Dr. Minakshi)
Patient has left white blood cells at another hospital.
Mistake: A 40 year old mild hypertensive complained of ED after a beta blocker
Reaction: Oh my god! What was the need of starting the drug so early?
Make sure that all mild hypertensives are first advised lifestyle modifications like exercise, low salt diet, high fiber diet, decreasing stress, etc. before advising anti hypertensive medications.

Situation: an elderly came with low back pain after a minor trauma
Dr Bad: Take this pain killer
Dr Good: Get x ray spine done
Lesson: A history of even minor trauma in an elderly patient presenting with back pain raises the red flag of suspicion for fracture and is sufficient reason to order plain radiograph of the spine.
£500 million spent on Tamiflu but experts say it doesn't work
Tamiflu does not work on healthy patients who get swine flu, experts have claimed. An investigation by the British Medical Journal has found no robust data to prove the anti viral medication prevents swine flu from becoming a serious condition. The research, published in the BMJ online, reviewed a number of studies looking at how well Tamiflu works in otherwise healthy patients. Dr Vivek Chhabra, 9899 79 8737
