Liver T2-weighted MR imaging: assessment of a three-dimensional fast spin-echo with extended echo train acquisition sequence at 1.5 Tesla.

Purpose: To retrospectively compare image quality and lesion detectability with two T2-weighted sequences at 1.5 Tesla (T): respiratory-triggered three-dimensional fat sat fast-spin-echo with extended echo-train acquisition (3D FSE-XETA) and respiratory-triggered two-dimensional fat-sat fast recovery fast-spin-echo (2D FRFSE).

Materials And Methods: MR was performed at 1.

Accuracy of multidetector computed tomography in differentiating primary epiploic appendagitis from left acute colonic diverticulitis associated with secondary epiploic appendagitis.

The objectives of this study are to evaluate the prevalence of left acute colonic diverticulitis (LACD) associated with secondary epiploic appendagitis (SEA) detected by computed tomography (CT); to describe CT features that distinguish LACD associated with SEA from primary epiploic appendagitis (PEA); and to assess the accuracy of CT in diagnosing LACD associated with SEA versus PEA. Institutional review board approval was obtained. We retrospectively identified 46 consecutive patients with LACD between July 2004 and July 2005 and 26 patients with PEA between 2000 and 2005 investigated using multidetector CT.

Location of the transition zone in CT of small-bowel obstruction: added value of multiplanar reformations.

Purpose: To assess the additional value of multiplanar reformations (MPR) in comparison with axial images alone for location of the transition zone in CT of mechanical small-bowel obstruction (SBO).

Materials And Methods: Sixty-nine consecutive patients with mechanical SBO underwent 16-slice multi detector row CT (MDCT). The gold standard for the precise location of the transition zone was established by two experienced abdominal radiologists, unblinded to clinical and surgical reports, reviewing all CT examinations.
