Sonographic Evaluation of the Yolk Sac

Sonographic Evaluation of the Yolk Sac

Abstract

This pictorial essay aims to inform related clinicians by summarizing the normal and abnormal sonographic findings of the yolk sac in the first trimester of pregnancy. An abnormality in the sonographic appearance of a yolk sac can predict subsequent embryonic death or abnormalities. Therefore, the accurate recognition of normal and abnormal sonographic findings concerning the yolk sac can be used to anticipate the course of pregnancy.

The secondary yolk sac is the first extraembryonic structure that becomes sonographically visible within the gestational sac. During embryonic development, the yolk sac is the primary route of exchange between the embryo and the mother. The yolk sac also provides nutritional, immunologic, metabolic, endocrine, and hematopoietic functions until the placental circulation is established.1 Therefore, the yolk sac is crucial in early embryonic life.

The yolk sac is one of the most important conceptional structures evaluated sonographically in the first trimester. At present, the most important benefit of sonographic evaluation of the yolk sac is confirmation of an intrauterine pregnancy.1,2 It has been hypothesized that sonographic features related to the shape, size, and internal structure of the yolk sac can be associated with the gestational outcome.1,3

This pictorial essay aims to inform related clinicians by summarizing the normal and abnormal sonographic findings of the yolk sac during the first trimester of pregnancy.

Sonography of Gastrointestinal Tract Diseases

Sonography of Gastrointestinal Tract Diseases

Abstract
Sonographic evaluation of the gastrointestinal (GI) tract may be difficult because of overlying intraluminal bowel gas and gas-related artifacts. However, in the absence of these factors and with the development of high-resolution scanners and the technical experience of radiologists, sonography can become a powerful tool for GI tract assessment. This pictorial essay focuses on sonographic findings of GI tract lesions compared with endoscopic, computed tomographic, and magnetic resonance imaging findings. Neoplastic and non-neoplastic diseases and postoperative complications are illustrated, and the distinctive sonographic characteristics of these entities are highlighted.

Sonography of Abdominal Wall Masses and Masslike Lesions

Abstract

Sonography is usually regarded as a first-line imaging modality for masses and masslike lesions in the abdominal wall. A dynamic study focusing on a painful area or palpable mass and the possibility of ultrasound-guided aspiration or biopsy are the major advantages of sonography. On the other hand, cross-sectional imaging clearly shows anatomy of the abdominal wall; thereby, it is valuable for diagnosing and evaluating the extent of diseases. Cross-sectional imaging can help differentiate neoplastic lesions from non-neoplastic lesions. This pictorial essay focuses on sonographic findings of abdominal wall lesions compared with computed tomographic and magnetic resonance imaging findings.

Thyroid image reporting and data system (TIRADS) | Radiology Reference Article | Radiopaedia.org

TIRADS is a risk stratification system for classifying thyroid lesions and was recently recognized in an American College of Radiology (ACR) white paper 1. Its use is being advocated similar to BIRADScategory for breast lesions. 

In 2017, a white paper 2 was released by the ACR committee on thyroid imaging with a standardised scoring system, with guidance on fine needle aspiration (FNA) and follow-up.
