[Retracted] Diagnostic Value of CT Window Technique for Primary Omentum Infarction

Figure 1

(A) Female, 30-year-old, primary omental infarction: 1 day of pain in the left lower quadrant of the patient, (a-d) the window width being 135HU, 250HU, 350HU, and 500HU, respectively. (a) There is no obvious abnormal performance. (b) A little blurry shadow around the descending colon. (c and d) The small piece of high-density shadow near the descending colon, and the surrounding fat gap is cloudy. (B) Male, 54 years old, primary omental infarction: 2 days of right lower quadrant pain, (a-d) the window widths 135HU, 250HU, 350HU, 500HU, respectively; no obvious abnormalities in (a and b), (c and d) image can clearly show a large flake blur shadow around the ascending colon, accompanied by turbidity around the fat gap. (C) Female, 22 years old, primary omental infarction: the patient’s left lower quadrant pain for 2 days, the image of the window width of 350HU and the changes after the enhancement. (a) Adjacent descending colon shown the density increased, the peripheral fat gap was blurred. (b-d) Were the arterial phase, the venous phase, and the delayed phase shown the lesions no enhancement.
