Dual Energy CT of the Pancreas
This article explores the technical background of dual-energy CT (DECT) imaging along with its basic principles, before turning to a review of the various DECT applications specific to pancreatic imaging. In light of the most recent literature, we will review the constellation of DECT applications available for pancreatic imaging in both oncologic and non-oncologic applications. We emphasize the increased lesion conspicuity and the improved tissue characterization available with DECT post-processing tools. Finally, future clinical applications and opportunities for research will be overviewed. (Source: Seminars in Ultrasound, CT and MRI)

Nonovarian Mimics of Ovarian Malignancy
Publication date: Available online 18 April 2019Source: Seminars in Ultrasound, CT and MRIAuthor(s): Mahesh ShettyOnce a pelvic mass is identified on an ultrasound examination, the first step in the differential diagnostic work up is to determine its origin. Most lateral pelvic masses in women are ovarian in origin, and the distinction between ovarian and nonovarian mimics of ovarian cancer is critical for appropriate clinical and surgical management. Adnexal masses detected on ultrasound can be further characterized by magnetic resonance imaging (MRI) when needed. Superior contrast resolution, multiplanar imaging, charact...

The role of PET/CT in the imaging of pancreatic neoplasms
Publication date: Available online 25 April 2019Source: Seminars in Ultrasound, CT and MRIAuthor(s): H. Duan, L. Baratto, A. IagaruABSTRACTPancreas cancer is a complex disease and its prognosis is related to the origin of the tumor cell as well as the stage of disease at the time of diagnosis. Pancreatic adenocarcinomas derive from the exocrine pancreas and are the fourth leading cause of cancer-related deaths in the US, while well-differentiated pancreatic neuroendocrine tumors (pNETs) derived from the endocrine part of the pancreas are rare and characterized by a slow growth and good life expectancy. Surgery is the only ...

Despite advances in cancer control and healthcare in general, mortality from ovarian cancer remains unacceptably high due to diagnosis at an advanced stage of the disease. The 5-year survival rate is only 47.4% because a majority of ovarian cancers are diagnosed when advanced. Only 14.9% of ovarian cancers are diagnosed when localized where the survival rate is 92.3%. Mortality rate reduction by screening has not been proven in women at a...

Adenomyosis as a Confounder to Accurate Endometrial Cancer Staging
This article aims to raise awareness of these staging issues and lists some of the relevant practical approaches. Adenomyosis reduces the accuracy of MRI in assessing the depth of invasion as it reduces the contrast between the endometrial cancer adenomyosis-involved myometrium. The article also offers an alternate argument for staging cancers where myoinvasion is found deep in the myometrium, arising from cancer-positive adenomyotic foci when the surface tumor is either limited to the endometrium or to the inner half of myometrium.
