Risk of Pulmonary Embolism in Patients With Isolated Great Saphenous Vein Thrombus
Risks associated with isolated great saphenous vein (GSV) thrombosis remain controversial. The purpose of this study is to identify the risk of pulmonary embolism (PE) in patients with isolated GSV thrombosis, particularly those with thrombus within 3 cm of the sapheno-femoral junction. A retrospective chart review of color flow Doppler lower extremity venous ultrasound examinations from an academic hospital from 2011 to 2016 was conducted. Seventy-eight patients were identified as having acute thrombus in their GSV and were then further stratified based on the presence or absence of concomitant deep venous thrombosis (DVT...

Hepatitis C–Associated B-cell Non-Hodgkin Lymphoma: A Pictorial Review
Conclusions
The cooccurrence of HCV infection and splenic lymphoma is a frequently encountered scenery. Ultrasonography, both conventional and contrast-enhanced, plays an important role in the exploration of the spleen, representing a first-line imagistic method and a valuable means of characterizing different types of splenic lesions.
Implications for Practice
This article states the importance of ultrasonographic evaluation regarding the splenic pathology, by revealing clinical and imagistic findings in 3 cases of hepatitis C–associated lymphoma. (Source: Ultrasound Quarterly)

The Application of Parametric Micro-Flow Imaging in the Evaluation of Liver Fibrosis
This study aims to investigate the application of parametric micro-flow imaging in the evaluation of liver fibrosis. From March 2013 to February 2014, 117 participants were recruited in this research prospectively, which includes 97 patients (who have been infected with hepatitis B virus or/and hepatitis C virus and have undergone liver biopsy) and 20 healthy volunteers. Contrast agent was injected as a bolus via the antecubital vein for the participants. Dynamic images of intercostal liver were collected and then divided into 30-second (30s) group and 10-second (10s) group. Color coding and quantitative analysis were perf...

Transient Elastography Identifies the Risk of Esophageal Varices and Bleeding in Patients With Hepatitis B Virus–Related Liver Cirrhosis
This study aimed to analyze the diagnostic accuracy of liver stiffness for predicting esophageal variceal grading and the risk of esophageal variceal bleeding (EVB) in cases of cirrhosis. Hematological and biochemical parameters were measured and transient elastography was performed in 88 patients with hepatitis B–related cirrhosis undergoing endoscopy for esophageal varices. Esophageal varices grade was highly correlated with liver stiffness measurement (LSM) and the liver stiffness spleen diameter-to-platelet score in cirrhosis. Compared with those from endoscopy, the LSM and the liver stiffness spleen diameter-to-plat...

Sonography of the Cecum: Gateway to the Right Lower Quadrant
Sonography of the cecum has come of age largely as a consequence of the successful evolution of appendiceal sonography as a useful tool in the evaluation of patients with right lower-quadrant pain. At some medical centers, graded-compression sonography (GCS) has become the initial imaging study of choice in the assessment of these individuals. The cecum serves as a helpful anatomic landmark for localization of the appendix in these examinations—providing a sonographic starting point in the search for the appendix. During GCS, primary pathology within the cecum itself can become evident, including a variety of processes, ...

Effect of Hepatic Inflammation in Chronic Hepatitis C Infection on Fibrosis Assessment by Arrival Time Parametric Imaging
Arrival time parametric imaging (At-PI) in contrast-enhanced ultrasonography is useful for assessing liver fibrosis in chronic hepatitis C (CHC) infection. The study aimed to elucidate the effect of hepatic inflammation on At-PI efficiency. Subjects were 159 CHC patients who underwent contrast-enhanced ultrasonography immediately before liver biopsy. Ultrasound contrast agent was injected, and contrast dynamics of the S5 to S6 region of the liver and right kidney were recorded for 40 seconds. The At-PI of liver parenchyma blood flow was generated using saved video clips. Hepatic blood flow during the first 5 seconds after ...

Serous Cystic Neoplasms of the Pancreas: Endoscopic Ultrasonographic Versus Computed Tomography and Magnetic Resonance Imaging Features of Surgically Removed Masses
Our purpose was to assess the endoscopic ultrasonography (EUS) features of serous cystic neoplasms (SCNs) of the pancreas in determining the surgical removal compared with computed tomography (CT) and magnetic resonance imaging (MRI) features. For 33 consecutive patients with 34 surgically confirmed SCNs over the past 11 years, preoperative EUS features were compared with those of CT and MRI (CT&MRI). Besides the lesion size and location, a retrospective analysis of the various imaging features was performed by 2 observers to understand the characteristics that determine the need for surgical intervention in terms of multi...

Gastric Lipoma: A Review of the Literature
Gastric lipoma is a rare benign tumor of the stomach. The imaging characteristics are diagnostic because the lesion has fat attenuation on computed tomography and demonstrates characteristics of fat on magnetic resonance images. On ultrasound, the lesion can be identified as a lesion hypoechoic to the gastric mucosa that is soft, but the mass cannot be displaced with compression. Identifying these imaging characteristics can prevent biopsy or surgery in asymptomatic patients. Although this lesion is benign, it can cause gastric obstruction. (Source: Ultrasound Quarterly)

Bowel Ultrasound for the Diagnosis of Necrotizing Enterocolitis: A Meta-analysis
Radiographic evaluation for necrotizing enterocolitis (NEC) often yields nonspecific findings. Bowel ultrasound (BUS) provides additional information beyond that of abdominal radiographs and may be helpful in the diagnosis of NEC in neonates. We systematically reviewed and aggregated existing literature to get a better estimate of diagnostic accuracy of BUS in the diagnosis of NEC. A literature search was performed using PubMed, Embase, and Cumulative Index to Nursing and Allied Health Literature to identify studies in which infants with clinically suspected NEC were evaluated using BUS. Studies that used modified Bell sta...

A 3-Dimensional Printed Ultrasound Probe Visuospatial Trainer
We describe a visuospatial trainer that replicates the housing of an ultrasound transducer, through which a linear laser projects light in the same plane and orientation as the ultrasonic sound waves. We use this trainer in combination with a porcine heart dissection laboratory to teach bedside cardiac ultrasound and transthoracic echocardiography (TTE). Off-the-shelf components, including an on/off switch, a laser, and 2 ampere batteries are connected in series and placed inside the 3-dimensional (3D)–printed housing. The trainer's laser emission projects a red line that visually represents the ultrasound's field. Learn...

Myofibroblastoma of the Breast: Ultrasonography, Mammography, and Magnetic Resonance Imaging Features With Pathologic Correlation
Myofibroblastoma (MFB) of the breast is an uncommon benign stromal tumor. Herein, we present histopathologically proven MFB that hyperechoic well-defined breast mass in the ultrasonography and circumscribed high-density mass in mammography. Additionally, internal septations and hyperintense appearance on magnetic resonance imaging are very valuable findings in the differential diagnosis of MFB. (Source: Ultrasound Quarterly)
