Siemens puts new spin on PET/CT with advanced hybrid scanner
December 3rd 2008Siemens Healthcare showcased at RSNA 2008 a PET/CT designed with radiologists in mind. It emphasizes CT performance and casts PET as the “smart contrast” that enhances the dynamic information delivered by CT. Siemens is pitching the CT component of its new Biograph mCT (molecular CT) as the most important part of the scanner and the PET component as delivering complementary information.
CT bests ultrasound for diagnosing ER patients with abdominal pain
The news was mixed for CT in the emergency department in research presented Wednesday at the RSNA meeting. CT was found to be better than ultrasound for diagnosing ER patients with abdominal pain, but radiation dose can be drastically reduced for patients suspected of appendicitis, according to authors of several studies.
Gamma imaging picks up cancer unseen by mammograms
December 3rd 2008Out of every 10 women whose mammogram or physical exam reveals potentially cancerous cells in their breasts, approximately three of them will have additional dangerous clusters the examinations missed, according to a recent study presented at the RSNA conference Wednesday.
Greater surgical precision possible with fMRI requires team approach
A neuroradiologist, a neurosurgeon, and a radiological technologist explained to an RSNA audience how working together to analyze fMR scans has significantly helped them pinpoint hard-to-reach brain tumors and plan delicate surgery, resulting in improved surgical outcomes.
Toshiba extends ultrasound reach in breast imaging
December 2nd 2008Toshiba America Medical Systems has positioned its MicroPure ultrasound technology as a way to better characterize microcalcifications. The new technology, showcased at RSNA 2008 on Toshiba’s Aplio XG ultrasound scanner, improves the detection of small calcifications that otherwise may evade detection with ultrasound.
Philips showcases value-priced ultrasound
December 2nd 2008Philips Healthcare showcased its new value-oriented HD15 ultrasound system at RSNA 2008. The latest addition to Philips’ HD product line, commercially released in summer, is designed for use in small hospitals, clinics, and private practices.
Core64, Core320 coronary CTA trials cross paths at meeting
The 2008 RSNA meeting serves as a reference point of sorts for two important trials testing the clinical efficacy of multislice cardiac CT. Results from the Core64 trials of 64-slice coronary CTA were published Nov. 28 while plans for a Core320 trial were announced in Chicago at the RSNA show.
Radiologists remain unaware of radiation reduction strategies
Most radiologists know about the medical risks associated with patient exposure to ionizing radiation, but many are still in the dark about basic steps they can take to reduce patient exposure. A University of Michigan survey presented at the RSNA meeting found that a surprising percentage were unaware of methods to adjust mA and kVp during CT procedures.
Critical results findings: Prototype system tells you whom to call
December 2nd 2008A prototype system developed by the University of Maryland was able, for a time at least, to dramatically boost and document the communication of critical results findings, according to a presentation Tuesday. It’s since been sent back to the drawing board for more work, but points to a solution to a problem that vexes radiologists nationwide.
Gymnastic complaints extend beyond common growth plate injuries
December 2nd 2008Adolescent gymnasts are developing a wider variety of arm, wrist, and hand injuries than previously described in gymnast-related medical literature, according to a retrospective review presented Monday at the RSNA meeting.
Database mining shows CT scans stable in children, climbing in adults
December 2nd 2008Researchers using a massive database of radiology reports to identify 10-year trends in scanning practices found mixed results. The good news: CT scans of children increased only slightly. In adults, however, they increased more than 50%, with abdominal and chest scans leading the way.
