MRI classification and characterization of complex ovarian masses:
Ovarian neoplasms range from benign to malignant and may be primary or secondary. Usually, they are classified by tissue of origin (surface epithelial, germ cell and sex-cord stromal) and metastatic (one secondary) (Table 1).In this article, ovarian masses are classified into three main MR imaging categories: Cystic neoplasms (with septations), Complex neoplasms (solid-cystic) and Solid neoplasms (predominantly solid). These three categories are further subdivided according to specific MR imaging features, such as the presence of calcifications, fat, blood, proteinaceous content and signal intensities.
Imaging of the Porta Hepatis: Spectrum of Disease
Offers a detailed overview of the anatomy of the liver’s hilum and the various diseases that can affect this complex region. It emphasizes the crucial role of different imaging techniques, such as ultrasound, CT, and MRI, in diagnosing and managing both vascular and nonvascular conditions. The document further elaborates on specific diseases like portal vein thrombosis, hepatic artery stenosis, and hilar cholangiocarcinoma, including their characteristic imaging findings. Finally, it highlights the porta hepatis as a significant pathway for the spread of abdominal malignancies.
MR Enterography in inflammatory bowel disease
This article explains the role of magnetic resonance enterography (MRE) in diagnosing and assessing inflammatory bowel disease (IBD), which includes Crohn’s disease and ulcerative colitis. The authors detail how MRE, a medical imaging technique, can visualize the small and large intestines to identify inflammation, structural changes, and complications associated with IBD. The piece compares MRE with other diagnostic methods like endoscopy, CT enterography, and ultrasound, highlighting its advantages in depicting submucosal pathology and differentiating between inflammation and fibrosis without using ionizing radiation. Furthermore, the article discusses patient preparation, MRE acquisition techniques, and image interpretation for both Crohn’s disease and ulcerative colitis, along with mentioning MRE’s potential in monitoring disease activity and guiding treatment strategies.
