Eric Barnes[email protected]Nuclear MedicineLung PET rules when CT is equivocal, discordantAlthough PET's high cost ensures that CT and radiography will remain the first-line lung cancer detection modalities for at least the near future, PET can be very useful adjunctively in patients whose diagnosis remains uncertain in the light of available radiographic and clinical evidence.July 11, 2005CTPart I: Simple steps ease cardiac CTA workflow in private practiceAuntMinnie.com is pleased to present the first installment of our two-part series on building a community-based CT angiography practice in an imaging center, based on discussions by radiologist Dr. David Dowe of Atlantic Medical Imaging in Galloway, NJ. Part I covers workflow and patient selection.July 7, 2005CTAuntMinnie.com CT Radiology InsiderJuly 4, 2005CTCT nips at MRI's heels in LV function studyThe results of an animal study by German researchers show that multidetector-row CT is largely equivalent to the gold standard MRI for determining left ventricular volumes and assessing wall motion in the setting of acute myocardial infarction.June 28, 2005CTVC CAD matches prone and supine imaging dataRewriting a page from standard clinical practice, CAD developers are using automated matching of prone and supine virtual colonoscopy datasets as their primary method of reducing false-positive candidates. And the nascent technique worked reasonably well, so long as the data were relatively free of collapsed segments and residual fecal matter.June 27, 2005Image-Guided SurgeryInterventionalists see safer RFA with coregistered laparoscopic US, CTBERLIN - Percutaneous radiofrequency ablation (RFA) and other minimally invasive interventions have become increasingly popular. But the interventionalists who perform them often end up working in the dark, as the CT or MR image they've placed across the room bears little resemblance to the laparoscopic ultrasound images used to guide the RFA needle. Researchers may have found a solution, according to a presentation at the Computer Assisted Radiology and Surgery (CARS) meeting.June 26, 2005CT3D diminution index spots lung nodules attached to blood vesselsBERLIN - A principal limitation of lung cancer imaging is the difficulty of distinguishing lung nodules attached to blood vessels from normal blood vessels, especially in CT data. But researchers from Japan have developed a 3D feature called the diminution index, which scans the CT pulmonary blood vessel data for signs of rapidly expanding shapes that can indicate a nodule rather than a blood vessel.June 26, 2005MRI4D MRI enables blood-velocity measurement in mitral valve insufficiencyBERLIN - Mitral valve insufficiency is a fairly common heart problem that lacks ideal imaging solutions. The problem lies in assessing regurgitant blood flow to determine the need for intervention. A presentation Thursday at the Computer Assisted Radiology and Surgery (CARS) meeting discussed the limitations in assessing blood flow, and highlighted a new measurement approach using time-resolved MRI vector fields.June 23, 2005Image-Guided SurgeryCARS suite of the future sees key role for image-guided interventionBERLIN - In Wednesday's opening session of the 19th International Congress of Computer Assisted Radiology and Surgery (CARS), Dr. Michael Vannier set forth his vision of the interventional suite of the future, and touched on the powerful forces shaping its development.June 22, 2005CTMDCT, MRI competitive in some bone lesion applicationsSAN FRANCISCO - Some facilities, and even a few researchers, have begun to favor the growing diagnostic capabilities of multidetector-row CT over MRI for assessing bone lesions. And they are daring to ask if CT might have advanced enough to take on MRI's robust characterization of many musculoskeletal pathologies.June 19, 2005Previous PagePage 206 of 258Next PageTop StoriesMolecular ImagingPET predicts faster cognitive decline in women than menWomen initially outperformed men at low brain tau levels, but the advantage diminished as tau levels increased over time.MRIUnclear explanations of contrast MRI exams heighten patient anxietyWomens ImagingMammography screening improves survival for late-stage cancersUltrasoundUltrasound MinnieCast, Episode 2: Body imaging with RUS-PATSponsor ContentHow Agentic AI Is Transforming Radiology Ops
