PURPOSE To evaluate a focused, helical computed tomographic (CT) technique for imaging the appendix in patients suspected of having appendicitis. MATERIALS AND METHODS One hundred patients prospectively underwent appendix CT examination, with use of oral and colon contrast media and contiguous, thin-collimation, helical CT imaging of the right lower(More)
Today, a wide range of traumatic and nontraumatic emergency conditions are quickly and accurately diagnosed with helical computed tomography (CT). Many traditional emergency imaging procedures have been replaced with newer helical CT techniques that can be performed in less time and with greater accuracy, less patient discomfort, and decreased cost. The(More)
PURPOSE Our goal was to determine the sensitivity, specificity, and diagnostic value of individual signs at helical appendiceal CT. METHOD Two hundred helical appendiceal CT scans (100 appendicitis and 100 normal appendix cases) were interpreted for individual signs of appendicitis. Scan findings were correlated with appendectomy or clinical follow-up(More)
OBJECTIVE We prospectively evaluated a helical CT technique in which contrast material is administered only through the colon for the imaging of suspected diverticulitis. SUBJECTS AND METHODS One hundred fifty consecutive patients who presented to our emergency department with clinically suspected diverticulitis underwent helical abdominal CT after(More)
PURPOSE To determine the changes in the computed tomographic (CT) appearance of primary epiploic appendagitis. MATERIALS AND METHODS Clinical records and CT scans were reviewed in 10 patients who were initially suspected of having diverticulitis or appendicitis but were later determined to have primary epiploic appendagitis. The scans were obtained at the(More)
UNLABELLED OBJECTIVE To evaluate the impact of appendiceal computed tomography (CT) availability on negative appendectomy and appendiceal perforation rates. SUMMARY BACKGROUND DATA Appendiceal CT is 98% accurate. However, its impact on negative appendectomy and appendiceal perforation rates has not been reported. METHODS The authors reviewed the medical(More)
BACKGROUND In patients with clinically suspected appendicitis, computed tomography (CT) is diagnostically accurate. However, the effect of routine CT of the appendix on the treatment of such patients and the use of hospital resources is unknown. METHODS We performed appendiceal CT on 100 consecutive patients in the emergency department who, on the basis(More)
BACKGROUND The authors determined the radiological misdiagnosis rate of primary epiploic appendagitis (PEA) and its impact on patient management and hospital resource use. METHODS A total of 660 computed tomography scans performed for clinically suspected diverticulitis (348 cases) or appendicitis (312 cases) were reviewed for cases meeting strict(More)
