MDCT imaging delivers higher organ doses than SDCT equivalent
CHICAGO - The use of multi-detector CT (MDCT) generates image sets of unparalleled diagnostic quality; however, obtaining these images using protocols equivalent to those used in single-detector CT (SDCT) acquisitions may be exposing patients to much higher radiation doses.

Digital radiography trumps film screen in chest imaging
CHICAGO - Personal preference as a metric of usability may sometimes seem arbitrary and contrived. However, researchers at M.D. Anderson Cancer Center in Houston, TX designed a study to measure radiologists' preference for film-screen x-rays vs. images acquired via digital x-ray that removed the capability for capriciousness.

Capitation caveats yield contract creativity
CHICAGO - According to recent estimates by the American College of Radiology, the demand for radiological services in the U.S. will increase by 6% annually over the next five years. The needs of an aging population, new technologies and services, and the capacity constraints of capital equipment, technologists and radiologists will all contribute to the growth of radiology.

Contrast-enhanced CT proves highly predictive of aortic injuries
CHICAGO - A differential diagnosis of acute thoracic aortic injuries (ATAI) must be based on many factors. At the department of diagnostic imaging in Naples, Italy, Dr. Mariano Scaglione and his colleagues have achieved a 100% positive predictive value in assessing ATAI with contrast-enhanced helical CT. Scaglione presented their results at the RSNA meeting on Sunday.

Fluoroscopy safety demands a plan
As the use of high-dose fluoroscopy for image-guided procedures increases, so does the potential for radiation-induced injuries. Hospitals and administrators should proactively require training and certification in radiation management, according to a Baylor College of Medicine physicist.

An intradecidual sign depicts transvaginal sagittal grayscale ultrasound imaging in a 34-year-old pregnant patient, which shows a 4-mm empty gestational sac (solid arrow) in the anterior endometrium. The location of the sac to one side of the central hyperechoic line (dotted arrows) representing the opposed innermost layers of decidualized endometrium confirms it is within the endometrium and not the endometrial cavity, hence the name intradecidual sign. This sign is helpful when seen to diagnose a probable intrauterine pregnancy before visualization of the yolk sac. Three days later, the yolk sac was visualized (not shown), allowing for the diagnosis of a definite intrauterine pregnancy.
