Shalmali Pal[email protected]CTStudies support breast CT's ability to heighten tissue contrast, resolutionThe search for an alternative to mammography continues with two recent studies that evaluated the role of CT in breast imaging. First, a group from the M. D. Anderson Cancer Center in Houston sought to determine how conebeam CT fared for breast tissue contrast and overall exam results. Then, researchers from the University of California, Davis, updated their ongoing investigation with the modality, looking specifically at improving image quality.January 24, 2008MRIStudy offers more evidence that multiple factors up NSF riskGadolinium-based contrast agents may not be the only culprit in the development of nephrogenic systemic fibrosis (NSF), and a new case report from the University of Texas in Galveston supports that theory. This multispecialty group reviewed a decade's worth of data, taking into consideration contrast-enhanced MR studies as well as a broad range of other risk factors.January 23, 2008MRI'Uniquely higher' relaxivity rates give gadobenate an edgeNot all gadolinium-based agents are created equal, and those agents with a higher relaxivity point offer a number of advantages in clinical MRI, according to a study in the American Journal of Neuroradiology. In this in vitro study, the investigators from the University of Pittsburgh in Pennsylvania demonstrated differences among various gadolinium-based contrast agents.January 22, 2008Womens ImagingAuntMinnie.com Women's Imaging InsiderJanuary 20, 2008Clinical NewsAnterior knee puncture approach technically on-target, well-toleratedKnee arthrography is generally used as the first-line imaging study before patients move on to MR or CT arthrography. The lateral patellofemoral approach is most commonly used for knee puncture, but it is a painful procedure and not always technically successful. Instead, French musculoskeletal radiologists have used an anterior approach for knee arthrography to good effect.January 13, 2008Digital X-RayStudies outline techniques for ramping up MR in renal artery imagingNephrogenic systemic fibrosis (NSF) continues to puzzle the MR imaging community, but patients with renal disorders must still undergo imaging exams and MRI remains the best option for detecting and grading kidney disease. Two recent studies offer advanced techniques for MR angiography (MRA) and MRI in the renal arteries. In both cases, gadolinium-based agents were used successfully without any serious side effects. AuntMinnie.com takes a look at the studies and discusses the role of gadolinium-enhanced MRA in this patient population with the authors.January 9, 2008MRIGadolinium release linked to overall stability of contrast agent, may trigger NSFGerman researchers believe they have found a qualitative correlation between nephrogenic systemic fibrosis (NSF)-like symptoms and the release of free gadolinium in an experimental study. In this animal model, a multiple-injection scheme was used to replicate the prolonged systemic exposure to contrast media that is experienced after repeated gadolinium administration in patients with severe renal impairment.January 8, 2008Radiation Oncology/TherapySuspicious findings by rad oncs at CT simulation merit look by radiologistRadiation oncologists who come across previously undetected findings during CT simulation have a responsibility to ensure that those images are reviewed by a diagnostic radiologist, according to researchers from the Henry Ford Health System in Detroit. While the group acknowledged that CT simulation images are not of the highest diagnostic quality, they can still yield clinically relevant information.January 3, 2008Radiation Oncology/TherapyAuntMinnie.com Radiation Oncology InsiderDecember 25, 2007Image Processing3D CT planning organizes acetabular fracture fragments into a surgical frameworkInternational orthopedic surgeons and trauma specialists have teamed up to develop a CT-based virtual 2D planning system for acetabular fracture reduction. The team tested a 2D CT data-driven virtual software application for more accurate planning in acetabular fracture operative reduction and internal fixation.December 23, 2007Previous PagePage 2 of 100Next PageTop StoriesISMRM 2024ISRMM: MRI useful in predicting tumor response in breast cancer patientsIntegrating MR elastography (MRE) in a routine MRI scanner could predict complete pathological response in breast cancer patients.ISMRM 2024ISMRM: PET/MRI shows promise identifying musculoskeletal ‘pain generators’ISMRM 2024ISMRM: What's next for MRI applications for MSK trauma?Radiology EducationARRS: Consistent disparities found in radiology residency matchSponsor ContentJourney to the Cloud: A Snapshot of Market Progress - May 22 @ 1pm EDT
