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 ...

Imaging and differential diagnosis of ovarian cancer
Publication date: Available online 25 April 2019Source: Seminars in Ultrasound, CT and MRIAuthor(s): Mahesh ShettyABSTRACTOvarian cancer is the seventh most common cancer affecting women. 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...

Rare solid tumor of the exocrine pancreas: a pictorial review
Publication date: Available online 25 April 2019Source: Seminars in Ultrasound, CT and MRIAuthor(s): Marco Dioguardi Burgio, Maxime Ronot, Valérie VilgrainAbstractNumerous other solid primary neoplasms may arise from the pancreas besides primary ductal adenocarcinomas and neuroendocrine tumors. Although diagnosis can be difficult because of the very low incidence of these tumors, knowledge of several, typical, epidemiological, biological and imaging features can help obtain a correct diagnosis. This pictorial review describes the features of solid rare primary pancreatic neoplasms on CT and MR imaging focusing on characte...

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.

Imaging and Staging of Endometrial cancer
Publication date: Available online 18 April 2019Source: Seminars in Ultrasound, CT and MRIAuthor(s): S.C. Faria, C.E. Devine, B. Rao, T. Sagebiel, P. BhosaleAbstractEndometrial carcinoma is the most common female pelvic malignancy in the United States. Although endometrial cancer is staged according to the International Federation of Gynecology and Obstetrics (FIGO) surgical system, early and accurate diagnostic assessment of disease status of gynecologic malignancies is important for optimal treatment planning and outcome prediction. Preoperative imaging may assist in evaluation of local extent and detection of distant me...

Nontraumatic Orbital Emergencies
Publication date: Available online 27 February 2019Source: Seminars in Ultrasound, CT and MRIAuthor(s): Prachi Dubey, Gaurav Jindal, Peter Lee, Gul MoonisNon-traumatic orbital pathology can often have overlapping imaging features and challenging timely diagnosis. Prompt recognition is necessary due to potential risk of permanent visual loss. In this article we present systematic evaluation of non-traumatic orbital pathology with attention to key imaging features, pathogenesis and potential complications.
