Radiosurgery advised for postpneumonectomy recurrent lung cancer
February 13, 2009 -- A large study of patients who developed contralateral lung cancer after having a pneumonectomy suggests that stereotactic radiation therapy is a curative option with minimal toxicity, even for high-risk patients with chronic obstructive pulmonary disease.
Hospital boss slams new NHS computer system
February 13, 2009 -- LONDON (Reuters), Feb 13 - An NHS hospital boss criticized the new computerized medical records system on Friday, saying it has cost an extra 10 million pounds to implement and is slowing the rate at which patients are seen.
Multislice CT can help guide surgery for infective endocarditis
February 13, 2009 -- NEW YORK (Reuters Health), Feb 13 - In patients with infective endocarditis, the accuracy of multislice CT for detecting valvular abnormalities is close to that of transesophageal echocardiography, and the newer technique could help in surgical planning, according to a report in the February 3 Journal of the American College of Cardiology.
320-detector-row CT cuts dose in triple rule-out exams
February 12, 2009 -- Image quality is high and radiation dose is low when the so-called triple rule-out protocol is used with 320-detector-row CT to scan patients with chest pain, according to researchers from Berlin.
Virtual colonoscopy beginners do better with 3D data
February 5, 2009 -- Novice virtual colonoscopy readers detect more polyps reading 3D endoluminal datasets of electronically cleansed data compared to 2D images. But experienced readers aren't daunted by either 2D datasets or fecal residues, turning in a similar performance regardless of the reading environment.
JAMA study finds wide variation in cardiac CTA dose
February 3, 2009 -- Coronary CT angiography (CTA) providers are failing to protect their patients from high radiation dose -- with dose levels varying widely between facilities, according to a new multinational study in the Journal of the American Medical Association.
CAD can boost double-reading detection rate
January 22, 2009 -- Computer-aided detection (CAD) technology may yield breast cancer detection improvements in an independent double-reading mammography screening practice, according to a research team led by Dr. Per Skaane, Ph.D., of Ullevål University Hospital in Oslo, Norway.
Adding delayed CT aids some trauma diagnoses
January 21, 2009 -- In the emergency setting, would the routine acquisition of a delayed scan five minutes after contrast lead to better diagnoses of trauma patients? It pays sometimes but not always to acquire the extra scan, say researchers from Italy, who reviewed images from hundreds of cases of organ injuries.
Thrombectomy a useful adjunct to primary PCI in STEMI: study
January 21, 2009 -- NEW YORK (Reuters Health), Jan 21 - Manual thrombus aspiration during primary percutaneous coronary intervention (PCI) improves myocardial reperfusion and reduces final infarct size in patients with ST-segment elevation myocardial infarction (STEMI), results of a European study indicate.
Ultrasound screens for pancreatic cancer in high-risk populations
January 19, 2009 -- SAN FRANCISCO - Ultrasound detected small pancreatic cancers even CT and MRI couldn't visualize in a novel Dutch screening program aimed at high-risk patients with a family history of the disease. The researchers hope to transform their pilot study into a multicenter trial aimed at finding pancreatic cancer in high-risk patients while it's still resectable.
