Shalmali Pal[email protected]MRIMRI depicts small lesions, predicts malignancy in lung cancerCT plays a major role in lung cancer imaging, with support from molecular imaging, sonography, and angiography. MRI also contributes to a greater understanding of small nodules, particularly with the recent introduction of improved protocols. Two new studies suggest that dynamic MRI and 3-tesla MRI can depict clinically significant small nodules, and also distinguish between benign and malignant lesions. In a related paper, Japanese nuclear medicine specialists looked at the value of MR for assessing cerebral lesions from metastatic lung cancer.August 2, 2007MRIAuntMinnie.com MRI InsiderJuly 29, 2007MRIMR adds value to urodynamics for imaging stress urinary incontinenceThe spectrum of abnormalities detected at MRI in women with stress urinary incontinence can be classified into two categories: findings related to urethral sphincter deficiency (ISD) and/or urethral hypermobility (UH). Researchers from Baltimore-based Johns Hopkins Medical Institutions assessed if MR findings could predict whether a patient had ISD or UH, and if those results could be correlated with urodynamics.July 26, 2007Radiation Oncology/TherapyBreast cancer radiotherapy parameters, patient age up chances of radiogenic lung damageLast month Philadelphia-based researchers confirmed that the risk of cardiotoxicity in women undergoing breast radiotherapy was quite low. Unfortunately, the same can't be said for potential damage to the lungs. In a new paper, Hungarian oncotherapists found connections between patient age -- and other factors -- with the risk of early and late lung sequelae after conformal radiation treatment of breast cancer.July 23, 2007Womens ImagingAuntMinnie.com Women's Imaging InsiderJuly 22, 2007MRIGadolinium-enhanced MR monitors postradiotherapy cancer cell deathThe accumulation of a gadolinium-based formulation in tumors can be used to map pre-existing necrosis and evaluate early tumor response, according to an experimental study done at the Houston-based University of Texas M. D. Anderson Cancer Center.July 18, 2007MRIMR parameters divulge depth of acute hamstring injuriesProfessional athletes and dancers are as familiar with hamstring strains as they are with the bench press and barre, respectively. Two studies affirmed MR's major role in defining these injuries. Australian and British researchers used the modality on football players for reinjury risk stratification, while Swedish sports medicine specialists looked at hamstring strains in dancers during slow-speed stretching. While the MR results didn't hold all the answers, the imaging exam was still worth performing, according to the experts.July 12, 2007MRIMR shows broad spectrum of findings in pregnant women with suspected appendicitisAlthough acute appendicitis is not terribly common in pregnant women, it does pose a diagnostic challenge because of anatomic and histologic changes that occur in these patients. CT carries a radiation risk while ultrasound, which is the established modality in this population, doesn't always deliver the whole story. Instead, Boston-based imagers have found success with MRI for evaluating the appendix, and more, in the gravid patient.July 2, 2007MRIParallel sequence plus high-field MR improves ankle imagingA technique called generalized autocalibrating partially parallel acquisition, or GRAPPA, offers images with "excellent" diagnostic quality and scan time reduction when paired with 3-tesla MR, according to researchers from two California-based institutions. They experimented with this protocol in symptomatic, cadaveric ankle specimens and healthy volunteers.June 28, 2007Musculoskeletal RadiologyAuntMinnie.com Orthopedic Imaging InsiderJune 17, 2007Previous PagePage 8 of 100Next PageTop StoriesUltrasoundCEUS impacts 2D shear-wave elastography liver assessmentContrast-enhanced ultrasound (CEUS) performed after 2D elastography could impact liver assessment.AIHow accurate are AI-generated depictions of radiologists?Molecular ImagingExtravasations rare in Lu-177 DOTATATE therapyPractice ManagementNew MR safety codes provide additional reimbursement for radiologistsCTCT, MRI reveal hidden brain changes linked to increased fall risk
