Color Doppler sonography of focal gastrointestinal lesions: initial clinical experience

Graded compression color Doppler sonography was used to evaluate
gastrointestinal blood flow in 20 normal fasting subjects and 32 patients
with focal gastrointestinal lesions. Imaging was optimized for color
sensitivity using a 5 MHz linear array transducer. Criteria were
established for normal mural blood flow based on findings in normal
controls. Two reviewers blinded to the final diagnosis compared patterns of
mural vascularity in normal and abnormal patients. Increased mural blood
flow was demonstrated in all 32 patients with gastrointestinal inflammatory
disorders and in seven of nine patients with neoplasms. No mural flow was
demonstrated in four patients with small bowel infarction. The greatest
overall degree of flow was noted in patients with Crohn's disease and
cytomegalovirus colitis. Flow in tumors was variable, ranging from
strikingly increased flow in a giant villoglandular polyp to absent flow in
a metastasis from lung carcinoma. Our preliminary experience suggests that
the presence of considerable overlap in the color Doppler patterns of mural
blood flow in inflammatory and neoplastic lesions. Color Doppler sonography
alone without spectral waveform analysis may not distinguish focal
inflammatory from neoplastic disorders of the gastrointestinal tract
reliably. However, this technique potentially may be useful in diagnosing
small bowel ischemia when thickened segments of small bowel are identified
with absent flow.
