Focal form of congenital hyperinsulinism clearly detectable by contrast-enhanced computed tomography imaging

Focal form of congenital hyperinsulinism clearly detectable by contrast-enhanced computed tomography imaging

The focal form of congenital hyperinsulinism (CHI) is characterized by a cluster of abnormal insulin-oversecreting β cells within a restricted area of the pancreas. Although identification of the focal lesion is very important in the management of CHI, it has been reported that imaging studies, including computed tomography (CT), magnetic resonance imaging (MRI) scans, or angiography, are not h...

Contrast Enhanced Computed Tomography

Contrast-enhanced cranial computed tomography in magnetic resonance imaging era.

OBJECTIVE To evaluate the usefulness of intravenous contrast administration in cranial computed tomography (CT) in a general hospital with a magnetic resonance imaging (MRI) facility, and to establish a protocol to determine which patients would benefit most from using contrast-enhanced cranial CT. SUBJECTS AND METHODS Five hundred and forty-seven patients who underwent routine nonenhanced CT...

congenital external carotid-external jugular arteriovenous fistula: diagnosis with contrast-enhanced computed tomography

the possibility of abnormal avf was considered and it was confirmed on contrast-enhanced computed tomography (ct), inferring that this modality is not only fast and non-invasive, but also accurate in detecting vascular abnormalities. herein, we report a 42-year-old woman with congenital avf between the external carotid artery and external jugular vein, presenting with palpitation and dyspnea. t...

Characteristics of focal liver lesions in arterial phase on contrast-enhanced ultrasound and contrast--enhanced computed tomography - comparative study.

BACKGROUND To compare the features of focal liver lesions in the arterial phase on contrast-enhanced ultrasonography (CEUS) and contrast-enhanced computed tomography (CECT). MATERIAL AND METHODS A total of 38 lesions in 29 patients with focal liver lesions (FLL) were examined with CEUS and CECT. The characteristics of the enhancement were determined, especially in the early arterial phase (0~...
