As an experienced journalist but a neophyte to radiology, I went to Chicago with a healthy mixture of curiosity and trepidation. I had prepared for the RSNA sessions I was assigned to cover but wondered if the megatechnical presentations would be over my head.

The California Department of PublicHealth has determined that excessiveradiation exposure to a two-year-oldboy who was allegedly subjected to151 CT scans while in the machinefor 65 minutes, leaving him with radiationburns on his face and head, wasdue to “operator error” by the radiologictechnologist.

Multislice CT coronary angiography is becoming a practical alternative to conventionalangiography.

Motivated by a $5000 bonus, radiologistsat Massachusetts GeneralHospital completed scan signoffs in afraction of the usual time.

As percutaneous transluminal angioplasty and stent placement replace bypass surgery in the treatment of peripheral arterial disease, cardiologists and surgeons now are performing far more of the procedures than radiologists

As percutaneous transluminal angioplasty and stent placement replaces bypass surgery in the treatment of peripheral arterial disease, cardiologists and surgeons now are performing far more of the procedures than radiologists, according to research presented Thursday at the RSNA meeting.

Computer-aided detection systems show high potential for detecting inconspicuous colonic polyps but provide little help in locating nonpolypoid colorectal lesions, according to research presented Wednesday at the RSNA meeting.

Stroke victims get faster “door-to-CT” time when departments communicate effectively, especially when emergency medical staff is called while the patient is en route to the hospital.

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.

More stringent criteria to evaluate emergency room patients under 40 years of age with suspected pulmonary embolism could decrease radiation exposure while also saving time and money, according to research presented at the RSNA meeting.

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.

Physicians who are experienced in performing multislice coronary CT angiography can diagnose better, but acquiring the expertise is a time-consuming effort.

When offered $5000 bonuses, motivated residents at Massachusetts General Hospital completed scan signoffs in a fraction of the usual time.

More stringent criteria to evaluate emergency room patients under 40 years of age with suspected pulmonary embolism could decrease radiation exposure while also saving time and money, according to research presented at the RSNA meeting.

During the annual meeting of the American College ofRadiology in May, several radiologists peppered thegroup's leadership with concerns over controversialplans for a sweeping overhaul of the certification examinationprocess.

Lifelong learning in an era of globalized healthcare science and practice is essential, according to Sunday’s opening session of RSNA 2008, which also stressed the need for standardization in training and certification.

A new technique may help characterize diffusion anisotropy in the spinal cord in a clinical setting. Researchers have determined that using 3D single-shot diffusion-weighted stimulated echo-planar imaging in the cervical spinal cord results in higher resolution and less distortion than 2D single-shot diffusion-weighted echo-planar imaging.

Highlights of the 2008 RSNA meeting include discussions about the use of CT angiography as a noninvasive technique for diagnosing coronary artery disease and the replacement of standard optical colonoscopy with CT colonography to screen for colon cancer.

Computer-aided detection significantly improves the sensitivity of pulmonary embolism imaging, according to a study that will be presented at the 2008 RSNA meeting. Other studies show that specially developed CAD schemes can detect flat lesions that are often missed in CT colonography.

Parents of a two-year-old boy are suing a California hospital after their son allegedly was subjected to more than 65 minutes of intermittent scanning in a CT machine, leaving him with radiation burns on his face and head.
