Dual energy spectral CT imaging of insulinoma—Value in preoperative diagnosis compared with conventional multi-detector CT

The Value of Nonenhanced Single-Source Dual-Energy CT for Differentiating Metastases From Adenoma in Adrenal Glands

“…However, DECT generates VMS images at energy levels ranging from 40 to 140 keV, which eliminates the averaging attenuation effects (23). This would increase contrast resolution.…”

Spectral CT imaging in the differential diagnosis of necrotic hepatocellular carcinoma and hepatic abscess

“…2,10 This imaging method has also found use in several clinical applications including preoperative detection of insulinomas, 10 diagnosis of pulmonary embolism, 11 and differentiating hypervascular hepatic lesions. 2,12,13 LV et al 13 reported use of spectral CT with fast tube voltage switching might increase the sensitivity for differentiating small haemangioma from small HCC in two-phase imaging.…”

Isoattenuating insulinomas at biphasic contrast-enhanced CT: frequency, clinicopathologic features and perfusion characteristics

“…According to previous reports, MDCT had a sensitivity of 63.3 to 94.4 % for detection and localization of insulinomas [9,10,19,20]. However, most previous studies are based on small patient groups, and the frequency of isoattenuating tumours were rarely mentioned.…”
