Eric Barnes[email protected]CTIncidental findings on CT spark disagreementMany radiologists disagree on the management of incidental findings detected at body CT scans, according to a study published in the November issue of the Journal of the American College of Radiology.November 1, 2011CTTechnology brings new opportunities in VC screeningCAMBRIDGE, MA - Technology is affecting virtual colonoscopy in ways that will improve the patient experience and increase the technique's detection accuracy, according to presentations at the 2011 International Symposium on Virtual Colonoscopy.October 26, 2011CTVirtual colonoscopy advocates press on for reimbursementCAMBRIDGE, MA - Virtual colonoscopy screening advocates were upbeat about their quest for reimbursement of the exam at this week's 2011 International Symposium on Virtual Colonoscopy. Which is not to say that getting doctors paid to perform virtual colonoscopy has been an easy struggle, or a particularly quick one.October 25, 2011CTLow-kV DECT finds more pathology with less radiation, contrastLow-kV dual-energy CT (DECT) of the abdomen is gaining currency as a CT technique that can reveal pathology hidden on traditional imaging techniques, using less radiation and less contrast media. It can also be performed using a variety of methods, each with its own strengths and weaknesses.October 17, 2011CTVC shows mostly advantages in postcolostomy surveillanceVirtual colonoscopy is technically feasible and less invasive than conventional colonoscopy for surveillance after sigmoid colostomy, according to a study in the October American Journal of Roentgenology. But better techniques are needed before it can be used routinely, the researchers said.October 13, 2011CT'Rapid prototyping' puts CT images in doctors' handsThese days, multidetector-row CT is producing vast quantities of 3D and 4D data for diagnostic and interventional use. But for all its multidimensionality, most of the output is still served up on a flat screen. That could be changing with a process called "rapid prototyping" that creates physical models from imaging data.October 11, 2011CT320-row scanner cuts contrast dose in coronary CTAContrast media dose can be reduced in coronary CT angiography (CCTA) scans acquired with a 320-detector-row scanner without significantly affecting image quality, according to a study in the October edition of the American Journal of Roentgenology.October 9, 2011CTJACC: CT calcium screening cost-effective only in menCT-based coronary artery calcium screening in individuals at intermediate risk of heart disease is probably cost-effective for men but not women, according to a new analysis in the October 11 edition of the Journal of the American College of Cardiology.October 5, 2011CTCT radiation may pose lower cancer risk for sicker patientsPatients with shorter life expectancies are at far less risk relative to those with a good prognosis when it comes to radiation dangers from medical imaging, conclude researchers in a new study in Radiology. The results may bring some relief to radiologists who feel that radiation risk has been overemphasized at the expense of clinical need.September 27, 2011CTJAMA: Men may require earlier colorectal cancer screeningA new analysis of colorectal adenomas found that men have significantly more advanced adenomas and colorectal cancers than women at all age groups, prompting the authors of the study in the Journal of the American Medical Association to recommend that men be screened earlier than women.September 27, 2011Previous PagePage 97 of 258Next PageTop StoriesMolecular ImagingPET links brain receptor to emotional numbing in PTSDTo date, only a single study has investigated CB1R availability in humans exposed to trauma.Womens ImagingCEM, DBT show promise for preoperative breast cancer stagingMRIMRI illumines how the brain maintains 'representation' of phantom limbsDigital X-Ray3D DEXA reveals lower bone density in diabetes patientsMRIGadolinium in ... beer?
