The Rare, the Odd, and the Atypical: A Pictorial Essay of Testicular and Paratesticular Diseases
Understanding a variety of scrotal diseases is essential to developing an accurate differential diagnosis and is critical in providing optimal patient care. Ultrasound is the imaging modality of choice when evaluating for scrotal pathology, with the major purpose of locating such pathology to either the testis, or epididymis, or other intrascrotal structures, as well as characterizing lesions as solid or cystic. It is generally assumed that most solid intratesticular masses are more likely malignant, whereas most extratesticular ones are benign, although some exceptions to that rule exist. This pictorial essay will focus o...

Utility of Longitudinal Measurement of the Liver With Ultrasound in Comparison to Computed Tomography Liver Volume in Assessing Hepatomegaly
In conclusion, liver length measured with US has only a moderate correlation with liver volume. Commonly used US liver length maximum values of 16 to 18 cm produce a significant number of false-negatives and false-positives for the diagnosis of hepatomegaly. (Source: Ultrasound Quarterly)

Biomechanical Cervical Assessment Using 2-Dimentional Transvaginal Shear Wave Elastography in Nonpregnant and Pregnant Women: A Prospective Pilot Study
This study evaluated the technical feasibility of 2-dimensional transvaginal shear wave elastography to quantify cervical stiffness in nonpregnant and pregnant women and established normal values in each group. With institutional review board approval, we performed a prospective study with an age-matched historical control design. Sixteen premenopausal nonpregnant women without cervical pathology and 17 low-risk pregnant women (gestational age 17–33 weeks) were enrolled. Cervical shear wave speeds were measured on a SuperSonic Aixplorer machine. The mean shear wave speeds of anterior cervix were 4.96 ± 1.96 m/s in nonpr...

Quantitative Evaluation of Shear Wave Elastography on Radiation-Induced Neck Fibrosis in Patients With Nasopharyngeal Carcinoma
The value of shear wave elastography (SWE) for quantitatively assessing neck fibrosis induced by radiotherapy (RT) in patients with nasopharyngeal carcinoma was evaluated over time. We prospectively observed 56 patients with nasopharyngeal carcinoma before and after therapeutic neck irradiation. The elasticity parameters including Emax and Emean were used to measure the stiffness of the bilateral sternocleidomastoid muscles. Twenty-seven patients completed a 1.5-year follow-up, with examinations beginning at 3, 6, 12, and 18 months after RT. Forty controls were recruited for reliability tests (along with the patients) and ...

Evaluation of the Clinical Effectiveness of Shear Wave Elastography in Pediatric Cases With Acute Appendicitis
To determine sensitivity and specificity of shear wave elastography in pediatric patients diagnosed with acute inflammation of the appendix. Forty-eight patients who were referred for abdominal pain, with 18 volunteers recruited for the evaluation. Alvarado scores were calculated on the patients. The elasticity and stiffness of the inflamed appendix tissues of patients and controls were measured using shear wave elastography. The anterior, posterior, and medial parts of the appendix tissue were measured, calculating the highest elasticity values in kPa. In the end, 32 patients with Alvarado scores between 7 and 9 (group 1)...

Efficacy of Shear Wave Elastography in the Differentiation of Acute and Subacute Deep Venous Thrombosis
It is important to know the age of clot formation to determine an appropriate treatment for deep vein thrombosis (DVT). The present study aims to differentiate between acute and subacute DVT using the shear wave elastography (SWE) technique. Patients with complaints no longer than 4 weeks and who were found to have early-stage (acute-subacute) thrombus on ultrasound (US) between January 2020 and May 2020 were included in the study. All of the patients underwent SWE using a Philips Healthcare EPIQ 5 Ultrasound System Inc. device with a high-resolution linear US probe (eL18-4, 22–2 MHz). Included in the study were 50 patie...

Application of Shear Wave Elastography to Evaluate the Stiffness of Normal Testes and Inflammatory Epididymal Tail Masses
This study aimed to investigate the application value of shear wave elastography in examining normal testes and inflammatory epididymal tail masses.
Methods
We examined 110 healthy male volunteers (with a total of 220 testes) and 25 patients with epididymitis via conventional scrotal ultrasonography and shear wave elastography. The mean (Emean), minimal (Emin), maximal (Emax), and standard deviation (ESD) values of elasticity were acquired. The inflammatory masses were assessed at initial diagnosis, at weeks 1 and 2 of standard anti-inflammatory treatment, upon remission, and at 2 weeks after remission.
Results

Comparison of Efficiencies Between Shear Wave Elastography, Fine-Needle Aspiration Biopsy and American College of Radiology Thyroid Imaging Reporting and Data System Scoring System in Determining the Malignity Potential of Solid Thyroid Nodules
We aimed to evaluate the efficiencies of quantitative shear-wave elastography, fine-needle aspiration (FNA) biopsy and American College of Radiology (ACR)-thyroid imaging reporting and data system (TIRADS) scoring system in determining the malignity potential of solid thyroid nodules. In period between September 2014 and January 2016, 191 solid thyroid nodules of 189 patients were enrolled in this study. The mean shear wave velocities of the nodules were recorded by acoustic radiation force impulse method. All nodules were classified according to ACR-TIRADS scoring system and underwent FNA procedure. The cytopathologic res...

Real-Time Tissue Elastography to Evaluate Hepatic Hypoxic-Ischemic Injury Caused by Brain Death
This study aimed to explore the potential of real-time tissue elastography (RTE) in evaluating hepatic hypoxic-ischemic injury caused by brain death. We performed RTE and biopsy for 50 donated liver. Hematoxylin-eosin staining was used to observe hepatocyte acidophilic change. Liver grafts were divided into 2 groups, one nonacidophilic change (n = 7) and the other with acidophilic change (n = 43). Correlation and difference analysis were performed for hematoxylin-eosin staining results and RTE parameters. The result indicated that 4 of the 11 RTE parameters, namely, the area of low strain within the region of interest (%AR...

Liver Stiffness Is Increased in Polycystic Ovary Syndrome and Related With Complement C1q/Tumor Necrosis Factor–Related Protein 3 Levels: A Point Shear Wave Elastography Study
Nonalcoholic fatty liver disease is very common in patients with polycystic ovary syndrome (PCOS). In patients with PCOS, the clinical use of liver stiffness (LS) and whether LS increases or decreases are still unclear. The purpose of this study was to determine the parameters related to LS and whether there is an increase in LS in patients with PCOS compared with healthy controls. Thirty-eight women diagnosed with PCOS according to Rotterdam criteria and 28 healthy age- and sex-matched controls were included in this study. In addition to routine follow-up parameters for all patients, serum homeostatic model assessment of ...
