Ascitic fluid may be differentiated from blood on CT on the basis of Hounsfield units (HU) and other radiographic characteristics (water: 0 HU; acute blood: 30-45 HU; clotted blood: 50-60 HU; extravasating blood: >85 HU).
However, the lesion in our patient was mistakenly believed to be a vascular malformation because the precontrast scan showed a homogeneous, well-defined soft-tissue attenuation of 40 Hounsfield units (HU) with intense postcontrast enhancement of 80 to 100 HU.
1) Owing to infiltration of the submucosa by fat, the inner layer mucosa are separated from the outer layer of muscularis propria/serosa (both being of soft tissue density) by a layer of fat (of low attenuation) measuring between-18 to-64 Hounsfield units.
In the algorithms positive calcification required a minimum density threshold of 130 Hounsfield Units and a minimum area threshold of 3 adjacent pixels of at least 130 Hounsfield Units.
Calibrated Hounsfield unit values were determined, using 3D-Doctor (Able Software Corp, Lexington, Massachusetts) and bone density was calculated from these values using a linear approximation.
The contrast media was a solution of polyethylene glycol (PEG 200, Scharer and Schlapfer AG, Rothrist, Switzerland) and iopentol (Imagopaque 300, GE Healthcare, Basel, Switzerland) in a mixture ratio of 10:1 (mean radiodensity, 600 Hounsfield units [HU]).
The detection of bone tissue has been obtained by using the optimal grey value, established between minimum value of 1628 and maximum value of 3056 Hounsfield units (HU) .
