Sensitivity and Positive Predictive Value for Lesion Detection Using Multiphase Computed Tomographic Enterography Among Patients With a Definitive Diagnosis of Small Bowel Bleedinga,b
| Type of lesion | Sensitivity | Positive predictive value |
|---|---|---|
| SB inflammation | 55.4% (31/56) | 93.9% (31/33) |
| SB mass | 90.2% (55/61) | 98.2% (55/56) |
| SB vascular | 41.9% (44/105) | 83.0% (44/53) |
| SB hemorrhage | 80.0% (4/5) | 100% (4/4) |
| Other lesions | 54.4% (31/57) | 75.6% (31/41) |
| Overall | 58.1% (165/284) | 88.2% (165/187) |
a
SB = small bowel.
b
Reference standard is a definitive diagnosis of small bowel bleeding through surgical, endoscopic, angiographic, or pathologic findings.
