Cynthia E. Keen[email protected]ISHealthcare IT saves lives, cuts costs, study findsHealthcare information technology produces tangible benefits in terms of fewer patient complications, lower mortality rates, and lower costs, according to a new study published this week by researchers from Johns Hopkins University in Baltimore. For every 1,000 patients, five fewer will die at hospitals that have the highest levels of computerization, according to the researchers.January 26, 2009ISRFID system automates conference attendance records of radiology residentsStanford University has found a high-tech way to maintain compliance with rules covering continuing medical education for residents: an automated attendance monitoring system using radiofrequency identification (RFID) technology. Based on the institution's experience, the system can help relieve paperwork headaches for residency program directors.January 25, 2009ISRadiologists underestimate overlooked SR report errorsThe accuracy of speech recognition (SR) software has improved dramatically since the first products were introduced for radiology reporting, but dictation errors still occur. A recent study at one institution found that radiologists underestimated the number of errors occurring in report generation via speech recognition.January 22, 2009Radiation Oncology/TherapyIMRT reduces risk of hearing loss in pediatric medulloblastoma patientsA study from Houston researchers confirmed that most pediatric medulloblastoma patients can be treated with intensity-modulated radiation therapy (IMRT) without the risk of severe hearing loss. The newer study produced results nearly identical to those from a smaller 2002 trial.January 18, 2009ISAuntMinnie.com Healthcare IT InsiderJanuary 18, 2009CTCT coronal reconstructions aid pediatric appendicitis diagnosisAdding coronal reformatted images to axial images in MDCT exams can improve the diagnosis of appendicitis in children, radiologists from Gachon University Gil Medical Center in Incheon, South Korea, have determined.January 11, 2009Clinical NewsStudy calculates radiation dose risk for infants in Belgian NICUA Belgian study has shed additional light on the amount of radiation dose delivered to infants in neonatal intensive care units (NICUs). The research provides reference values for NICU radiation dose, and also offers guidance on collecting dose measurements and converting them into organ-dose values.January 7, 2009Radiation Oncology/TherapyStereotactic radiosurgery adequate for treating brain metastasesU.S. researchers have found that adding whole-brain radiation therapy to stereotactic radiosurgery isn't necessary for treating patients with brain metastases. In fact, adding whole-brain radiation more than doubles a patient's risk of cognitive decline compared to those who receive only stereotactic radiosurgery.January 6, 2009Radiation Oncology/TherapyInternal mammary node biopsies needed for better RT planningA large study of breast cancer patients reveals that only 5% of patients with cancer-positive internal mammary nodes who receive radiation therapy (RT) will die of breast cancer recurrence within five years. This survival rate is comparable to patients with positive axillary lymph nodes who receive radiation therapy.December 30, 2008Radiation Oncology/TherapyLawsuit hits Canadian cancer center for radiation therapy errorsA Canadian cancer center has been hit with a class action lawsuit claiming that hundreds of patients received improper levels of radiation during radiation therapy treatments over a three-year period.December 29, 2008Previous PagePage 76 of 88Next PageTop StoriesCTMachine learning plus CT helps assess severity of COPDA machine-learning model based on chest CT images accurately predicts lung function, which can help clinicians diagnose and assess COPD.UltrasoundActive thyroid surveillance effective, beneficial for older patientsMolecular ImagingFES-PET shows promise staging women with invasive lobular cancerCTStructured CT reporting tool may aid hernia detection after bariatric surgeryMRIHigher ventricular and atrial heart volumes boost cardiac disease risk
![Pittsburgh Compound B (PiB) PET distribution volume ratio (DVR) images were projected onto fsaverage surfaces from FreeSurfer and surface smoothed, with PiB (amyloid) slope maps created using ordinary least squares regression (time as only factor) and mixed effects models for 154 participants run at each vertex (P < .01; model: longitudinal Geriatric Depression Scale score estimated by amyloid slope × time + [sex + education + age] × time). This map visualizes the results of the linear mixed-effects models (t score of the main variable, amyloid slope × time) such that regions with a greater t score (red) represent areas in which greater depressive symptoms are associated with greater amyloid accumulation (amyloid slope).
