Low-dose CT detects kidney stones as well as high-dose
CT protocols used by researchers at Loma Linda University decreased radiation dose up to 95% when de-tecting distal ureteral calculi.
CT protocols used by researchers at Loma Linda University decreased radiation dose up to 95% when detecting distal ureteral calculi. The researchers used ultralow-dose CT as opposed to unenhanced multidetector CT.
A total of 85 calcium oxalate stones 3 to 7 mm long were prospectively placed in 14 human cadaveric distal ureters in 56 random configurations. The intact kidneys, ureters, and bladders were placed in the cadavers and CT was performed at 140, 100, 60, 30, 15, and 7.5 mA sec (J Urol 2009;182[6]:2762-2767).
Overall sensitivity and specificity were 98% and 83%. Imaging using 7.5 mA sec settings resulted in 97% sensitivity. Specificity was 84%.
Can Short-Term Measures Provide Some Relief with the Radiologist Shortage?
April 4th 2024In an attempt to navigate the imbalance between rising imaging volume and a shortage of radiologists, researchers proposed a variety of measures that may provide additional resources, bolster productivity, and help mitigate burnout.
