This study aimed to assess ultrasonography (US) features of normal submandibular parenchyma (NSP) and incidental diffuse submandibular disease (DSD). From January 2013 to December 2017, 39 patients underwent preoperative US of the submandibular gland before submandibular surgery in our hospital. Among them, 9 were excluded because of inadequate histopathologic data (n = 7) or poor US image quality (n = 2). The US features of the resected submandibular glands were retrospectively investigated by a single radiologist, blinded to clinicoserological information and the histopathologic result, using a picture archiving and communication system...

Ultrasound is an essential tool in evaluating the underlying etiology of scrotal lesions, which range from traumatic, infectious, inflammatory, congenital, and neoplastic conditions. Understanding the sonographic characteristics of benign scrotal masses is essential for a radiologist to determine whether conservative management is appropriate or if more aggressive follow-up or treatment is necessary. While surgical intervention may sometimes be necessary, combining the clinical presentation and imaging appearance can sometimes lead to a confident radiologic diagnosis that spares the patient from surgery...

Patients with type 2 diabetes mellitus (DM) have been shown to have increased liver fibrosis (LF) as determined by liver elastography. However, the data on LF incidence in patients with prediabetes are scarce. This study was undertaken to determine the incidence of LF and associated parameters in prediabetic patients. Three study groups with equal number of participants defined on the basis of glucose metabolism status were included the following: normal glucose metabolism (NGM), prediabetes, and newly diagnosed type 2 DM (55 patients in each group)...

Portal venous system evaluation is required in many clinical circumstances, as substantial morbidity and mortality can be associated with a spectrum of portal vein abnormalities. Portal venous system pathologies can be congenital or acquired, and the knowledge of their imaging appearances will allow for a confident diagnosis and appropriate treatment options. In addition, a firm understanding of anatomical variants is important for planning surgical procedures and percutaneous interventions of the liver. This article will review various imaging appearances of portal venous systems abnormalities...

Congenital variants of the gallbladder development are infrequent and sometimes represent an asymptomatic imaging finding. In this case series, we want to present multimodality imaging findings that permit the diagnosis. Ultrasound, multidetector computed tomography, and magnetic resonance images are included.The proper recognition of these infrequent congenital benign entities avoids unnecessary complementary examinations and misdiagnosis. Although ultrasound represents the most commonly used initial diagnostic tool, the increased use of magnetic resonance imaging and the wide use of multidetector computed tomography make it crucial to know how these entities are seen...

In the interscalene groove, nerve structures are in close proximity and may not be visible as separate structures, increasing the risk of insertion of the needle tip within the epineurium. We evaluated whether experienced regional anesthesiologists can distinguish between nerve elements lying in close proximity on ultrasound images.Brachial plexus elements from 4 nonpreserved cadavers were arranged in a water bath. Ultrasound images of the nerve roots and trunks were taken. Regional anesthesiologists and residents were asked whether they could distinguish the nerves as 2 separate structures and if they could identify a pair of nerve roots versus a single trunk...

To distinguish malignant cervical lymphadenopathy, we established a new scoring system based on ultrasound features. Two hundred sixty-three patients with cervical lymphadenopathy received ultrasonic examination and underwent ultrasound-guided core needle biopsy or fine needle aspiration. The scoring system was proposed by multivariate logistic regression analysis and compared with Liao scoring system (0.06 × age + 4.76 × shortest-to-longest axis ratio + 2.15 × internal echo + 1.80 × vascular pattern). A new scoring system model, 1...

BACKGROUND: Pneumonia is one of the most frequent widespread and severe infectious diseases in pediatric patients worldwide. Pneumonia is characterized by high incidence and possibility of complications in the course of the disease in pediatric patients. For this reason, there is a need to have a rapid and safe diagnostic method to recognize it. Imaging diagnostic tools, such as x-ray examinations, necessitate caution while using these methods. To date, there have been lots of studies with the aim to determine the role of lung ultrasonography (LUS) in the diagnosis of inflammatory lesions in children...
