Ultrasound Evaluation of the Axilla in the Breast Imaging Setting
This article will review ultrasound techniques and the anatomy and the morphology of axillary lymph nodes. Lymph node staging in breast cancer will also be discussed. Ultrasound-guided interventions and localizations and emerging technologies of elastography and contrast-enhanced ultrasound will be discussed. In addition, this article will discuss the role of ultrasound as it applies to management of the axilla since the American College of Surgeons Oncology Group Z011 and Z1071 trials. Finally, other causes of benign and malignant axillary lymphadenopathy, not related to breast cancer, are discussed. (Source: Ultrasound Quarterly)

Granulomatous Mastitis: What Radiologists Should Know With Imaging Examples of Biopsy Proven Cases
Granulomatous mastitis is a rare benign inflammatory disease of the breast, predominantly affecting women of childbearing age. Because of its low prevalence, the literature is limited, and its treatment algorithm is unclear. However, it is important to understand this disease for timely diagnosis and treatment. Our overview with imaging examples of biopsy-proven cases aims to improve our knowledge and to determine when it would be appropriate to include it in the differential diagnosis.

A Comparison of the Diagnostic Value of Positron Emission Tomography/Computed Tomography and Ultrasound for the Detection of Metastatic Axillary Nodal Disease in Treatment-Naive Breast Cancer
The objective of this study was to describe the diagnostic value of positron emission tomography/computed tomography (PET/CT) and ultrasound (US) for identifying metastatic axillary disease in primary breast cancer. This is a retrospective review of 240 patients with treatment-naive unilateral primary breast cancer of at least stage T2. Eighty-five patients met our inclusion criteria. Initial whole-body PET/CT and axillary US examinations were reviewed and compared with the criterion standard of fine-needle aspiration cytology. Sensitivity, accuracy, and positive predictive value (PPV) for each modality were computed. Beca...

Ultrasonography-Based Radiomics of Screening-Detected Ductal Carcinoma In Situ According to Visibility on Mammography
Ductal carcinoma in situ (DCIS) has different prognostic factors according to the detection modality. The purpose of this study was to compare parameters from a radiomic analysis of ultrasonography (US) images for DCIS detected on screening mammography (MMG) and US and detected on screening US only. A total of 154 surgically confirmed DCIS visible on US were included. Regions of interest were drawn onto US images of DCIS, and texture analysis was performed. Lesions were classified into those detected by both US and MMG (the US-MMG group) and those detected by US only (the US group). Analysis parameters were compared betwee...

Predicting Response to Neoadjuvant Chemotherapy in Locally Advanced Breast Cancer After the Second Cycle of Chemotherapy Using Shear-Wave Elastography—A Preliminary Evaluation
The primary objective of the study was to determine whether shear wave elastography can be used to predict the response of neoadjuvant chemotherapy (NACT) in women having invasive breast cancer. A prospective study involving 28 patients having invasive breast cancer and undergoing NACT followed by surgery was done after institutional review board approval. All the patients underwent 2-dimensional B-mode ultrasound and 2-dimensional shear wave elastography before the start of chemotherapy and after 2 cycles of completion of chemotherapy, and mean stiffness was recorded. The patients were segregated to responders and nonresp...

Medical Student Ultrasound Education: The Radiology Chair Weighs In
To assess the radiology department chairs’ opinions concerning current status and plans for teaching ultrasound to medical students, the American College Taskforce on Radiology Ultrasound Education, commissioned by the American College of Radiology, distributed a survey to 142 radiology chairs and a medical school dean subgroup.

Diagnostic Efficiency of Gynecologic Imaging Reporting and Data System Combined With 3-dimensional Contrast-enhanced Ultrasound Scoring System in Evaluating Ovarian Tumor
To estimate the value of gynecologic imaging reporting and data system (GI-RADS) combined with 3-dimensional contrast-enhanced ultrasound (3D-CEUS) scoring system in the differential diagnosis of ovarian tumor. Both of 2-dimensional ultrasound (2D-US) and 3D-CEUS were performed on 114 patients with ovarian masses by Voluson E8 with SonoVue (Bracco, Italy). Besides, dynamic contrast-enhanced-magnetic resonance imaging (DCE-MRI) (Siemens Magneton Verio 3.0T, Germany) was performed on the patients. There were totally 62 benign and 52 malignant ovarian tumors in all patients. The ability of GI-RADS combined with 3D-CEUS scorin...

The Change in the Renal Pelvis Anterior-Posterior Diameter Between Prevoiding and Postvoiding Status, and Its Correlation With Vesicoureteral Reflux
In this study, our aim was to evaluate the significance of the change in renal pelvis anterior-posterior diameter (RPAPD) before and after micturition between vesicoureteral reflux (VUR)-positive and -negative patients to whom had voiding cystourethrography (VCUG) was performed.

Comparison of Superb Microvascular Imaging With Other Doppler Methods in Assessment of Testicular Vascularity in Cryptorchidism
Superb microvascular imaging (SMI) is a new Doppler technique. Superb microvascular imaging can observe microvascular and low-velocity blood flow. Superb microvascular imaging is available in 2 modes: color SMI (cSMI) and monochrome SMI (mSMI). To evaluate testicular flow, we have compared color Doppler ultrasound (CDUS), power Doppler ultrasound (PDUS), Advanced Dynamic Flow (ADF), cSMI, and mSMI techniques. (Source: Ultrasound Quarterly)

Quantification of Hepatic and Splenic Stiffness After Fontan Procedure in Children and Clinical Implications
We aimed to investigate Fontan associated liver disease in children by shear wave elastography (SWE). This is a single-center, prospective case-control study included 41 patients with Fontan physiology and 30 healthy controls. Hepatic and splenic shear wave elasticity values were exhibited both as kPa and m/s. The mean hepatic SWE values of Fontan patients (n = 41; 15.8 ± 3.2 kPa or 2.5 ± 1.8 m/s) were significantly higher than the control group (n = 30; 5.59 ± 0.6 kPa or 1.37 ± 0.07 m/s) (P (Source: Ultrasound Quarterly)

Cognitive Versus Magnetic Resonance-Ultrasound Fusion Prostate Biopsy: Which One Is Worthier to Perform?
The aim of our study is to compare 2 prostate fusion biopsy models in terms of accurate target sampling. One hundred patients who had Prostate Imaging-Reporting and Data System score 3, 4, or 5 lesions (lesion diameter,>5 mm in long axis) in multiparametric-magnetic resonance imaging and prostate-specific antigen levels between 3 and 10 ng/mL were enrolled in the study. All patients were biopsy naive. Two groups were composed with 50 patients each. Group 1 patients had cognitive fusion (CF) biopsy, and group 2 had magnetic resonance-ultrasound fusion platform biopsy. After fusion biopsy, standard biopsy was also performed....

Accuracy of Bedside Lung Ultrasound as a Rapid Triage Tool for Suspected Covid-19 Cases
This study was a prospective, cross-sectional cohort study. During their shifts, 3 accredited and certificated emergency physicians performed BLUS using BLUE protocol at the triage area of the ED on patients with suspected Covid-19. All of the patients underwent chest computed tomography. The BLUS findings were statistically compared with formal radiology reports of computed tomographies as the criterion standard for the diagnosis of Covid-19 pneumonia. Kolmogorov-Smirnov analysis, Shapiro-Wilk test, and Q-Q plots were performed with 95% confidence intervals (CIs) for statistical analysis.
