Eric Barnes[email protected]CTNo problems after discharge for negative coronary CTAMonday, November 30 | 3:10 p.m.-3:20 p.m. | SSE03-02 | Room S502ABA negative coronary CT angiography (CTA) exam allows hospitals to send chest pain patients home and clear the backlog in the ER. But is it really safe? How do patients do over time? Researchers from the University of Washington School of Medicine in Seattle wanted to find out.November 15, 2009CTExperiment validates use of CT for in-stent stenosis assessmentMonday, November 30 | 11:50 a.m.-12:00 p.m. | SSC02-09 | Room S503ABInvestigators from Brigham and Women's Hospital in Boston scanned a series of phantom coronary artery stenoses to validate CT assessment of coronary artery stenoses. They will discuss their results in this Monday scientific session presentation.November 15, 2009CTLack of risk factors, D-dimer results rule out PEMonday, November 30 | 11:35 a.m.-11:45 a.m. | VC21-15 | Room S103CDWhile CT angiography (CTA) is the modality of choice for pulmonary embolism (PE), it is over-ordered, costly, and produces high radiation exposure. California researchers sought to determine the positivity rate of CTA, and whether thromboembolic risk factors can accurately indicate pretest PE probability.November 15, 2009CTHigh-pitch imaging cuts cardiac CT dose, improves image qualityTuesday, December 1 | 11:10 a.m.-11:20 a.m. | SSG18-05 | Room S403ABPhase-correlated imaging procedures represent the state of the art for cardiac CT angiography; however, the technique requires low pitch factors that increase the applied dose. In this study to be presented on Tuesday, researchers from Germany evaluated the potential benefits of high-pitch acquisition schemes.November 15, 2009CTProspectively triggered CT angiography takes on patients with arrhythmiasMonday, November 30 | 11:10 a.m.-11:20 a.m. | SSC01-05 | Room S502ABWhile prospective electrocardiogram (ECG)-triggering typically applies just a fraction of radiation exposure used in retrospective ECG gating, it also comes with two historical disadvantages -- solutions for which will be discussed in this scientific session presentation.November 15, 2009CTDose-length product more accurate for measuring cardiac CT doseMonday, November 30 | 10:40 a.m.-10:50 a.m. | SSC02-02 | Room S503ABGlobal chest CT conversion factors, which are often used to calculate effective dose at cardiac CT, do not account for the variability of dose distribution with the procedure, according to radiation physicist Walter Huda, Ph.D., from the Medical University of South Carolina in Charleston.November 15, 2009CTUltralow-dose 256-detector-row VC maintains sensitivitySunday, November 29 | 12:05 p.m.-12:15 p.m. | SSA08-09 | Room E353AData indicate that virtual colonoscopy is safe, and the standard low radiation dose is not likely to be important in the ≥ 50-year-old population who may undergo the exam for screening. Nevertheless, using the lowest possible dose is desirable, and results from this study indicate image quality can be maintained with 256-detector-row VC while dose is reduced.November 15, 2009CTContrast exposure in utero shows little effect on thyroid functionSunday, November 29 | 11:15 a.m.-11:25 a.m. | SSA09-04 | Room E351Citing concerns about the risk of thyroid dysfunction in newborns after they are exposed in utero to iodinated contrast media, researchers from Warren Alpert Medical School of Brown University in Providence, RI, tested contrast-exposed neonates for answers.November 15, 2009CTRoad to RSNA 2009: CT PreviewNovember 15, 2009CTCedars-Sinai raises tally of radiation overdose casesMore patients received excessive radiation doses during brain perfusion CT scans than previously thought, according officials from Cedars-Sinai Medical Center in Los Angeles. The medical center also said that it has offered free medical care for patients who are affected.November 12, 2009Previous PagePage 138 of 258Next PageTop StoriesNuclear MedicineLLMs rapidly evolving in nuclear medicineLarge language models (LLMs) are widely used to handle the large volume of text data generated in nuclear medicine.MRIDWI with fat correction identifies liver scarring in MASLD patientsUltrasoundGhost scans problematic in POCUS trauma examsMolecular ImagingPSMA-PET may require selective use to be cost-effectiveSponsor ContentJoin Us!
