Multiple pancreatic insulinomas: multislice CTEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We present a case of a patient who had three abdominal CT scans over 10 years for the detection of pancreatic insulinomas. The first was made on an incremental CT and showed no lesion, the second on a single-slice helical CT which revealed a single centimetric tumor of the head of the pancreas, and the third on 64-slice CT which revealed 5 infracentimetric tumors. We do not know if all were present at the first scan but it is possible that these small tumors could have been missed on thick CT scan slices with overlap. The ideal imaging technique for the detection of endocrine pancreatic tumor is not known yet. Th...

Endovascular intervention for renal artery stenosisEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract Renovascular diseases are common conditions with important implications on cardiovascular morbidity and mortality. Renal artery stenosis (RAS) is present in 1–5% of patients with hypertension (HTN) in the US with the vast majority of caused by atherosclerosis. Atheroscelortic RAS is related not only to uncontrolled HTN, but also to renal dysfunction. Atherosclerotic RAS in the USA has been reported to account for approximately 14–16% of new patients requiring dialysis each year. Hence a concerted effort was made in the last decade to treat renovascular stenosis using newly developed endovascular...

Abstract Our aim is to compare the radiation dose associated with a low-dose CT colonography (CTC) protocol for colorectal cancer screening with that delivered by double-contrast barium enema (DCBE). CTC of twenty asymptomatic individuals (M:F = 10:10) participating to a colorectal cancer screening program and DCBE of fifteen patients (M:F = 6:9) were evaluated. For CTC, absorbed dose was determined by calculating the dose-length product for each CTC examination from measurements on a CT dose phantom equipped with a CT ion chamber. For DCBE, the free-in-air Kerma at the patient’s X-ray ...

Flat lesions in CT colonographyEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract Flat lesions have been a source of controversy because of concerns that CT colonography (CTC) is insensitive in detecting these lesions, yet they may harbor a high incidence of advanced neoplasia. The wide variation in the reported incidence of flat lesions may in part be due to the lack of a uniform definition of “flat”, and in fact in many prior reports the inclusion criteria for flat are not even clearly specified. Emphasis on the more recent CTC literature suggests that when limited the target lesion to neoplasia (adenomas or adenocarcinoma), the incidence of flat lesions is low and most can...

Colonic Crohn’s disease: value of magnetic resonance colonography for detection and quantification of disease activityEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract Conventional colonoscopy combined by histological examination, represents the standard for the evaluation of colorectal pathologies and usually is the first examination for the evaluation of patients with suspected or established diagnosis of Crohn’s disease (CD). However, information provided by colonoscopy is limited to mucosal alterations since the technique is unable to evaluate transmural changes or presence of extraluminal complications such as abscesses or fistula. Technological advances in magnetic resonance (MR) raised expectations on the potential role of this imaging modality for evalua...

Surgical resectability of pancreatic adenocarcinoma: CTAEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Abstract Imaging studies play an important role in the diagnosis and management of patients with pancreatic adenocarcinoma. Computed tomography (CT) is the most widely available and best validated modality for imaging these patients. Meticulous technique following a well-designed pancreas protocol is essential for maximizing the diagnostic efficacy of CT. After the diagnosis of pancreatic adenocarcinoma is made, the key to management is staging to determine resectability. In practice, staging often entails predicting the presence or absence of vascular invasion by tumor, for which several radiologic grading ...
