An anomalous origin of the right coronary artery from the opposite sinus of Valsalva with an intramural course (R-ACAOS-IM) may cause sudden cardiac death in children and adolescents. However, the natural history and management of patients in whom this anomaly is detected later during adulthood remains uncertain. The goals of this study were to assess the impact of an R-ACAOS-IM on the clinical outcomes in an adult population and to determine if adult patients with this anomaly who do not have significant coronary artery disease (CAD) can be managed safely without surgical intervention.

Background: Management of complex renal cysts is guided by the Bosniak classification system, which may be inadequate for risk stratification of patients for intervention. Fractional tumor vascularity (FV) calculated from volumetric contrast-enhanced ultrasound (CEUS) images may provide additional useful information.
Objective: To evaluate CEUS and FV calculation for risk stratification of patients with complex renal cysts.
Purpose: Ultrasound's versatility and ease of use has expanded its application in many clinical settings. Technological advancements with contrast-enhanced ultrasound (CEUS) have allowed high quality imaging similar to CT or MRI with lower risk of contrast toxicity and radiation exposure. In this review article we examine the development of CEUS and its vast applications in the field of urology.

Purpose: To evaluate changes in utilization of cardiac imaging-transthoracic, transesophageal, and stress echocardiography (TTE, TEE, and SE), coronary CT angiography (cCTA), cardiac MRI (cMRI), myocardial perfusion imaging (MPI), and cardiac positron emission tomography (cPET).
Materials And Methods: The 2010-2019 Physician/Supplier Procedure Summary files were used to find imaging utilization per 100 000 Medicare beneficiaries. Global and professional claims were aggregated, representing total interpretive services.
Purpose: To determine if Medicaid expansion is associated with increased volumes of lung cancer screenings.
Methods: A quasi-experimental study was performed to compare the annual growth rates in lung cancer screenings between states that expanded Medicaid (n = 31) versus those that did not (n = 17). Using the American College of Radiology Lung Cancer Screening Registry, we calculated the average annual growth rate between 2016 and 2019 for both groups.
Ultrasound guidance allows performance of carpal tunnel release with smaller incisions and quicker recovery than traditional open or endoscopic surgery. The purpose of this study was to evaluate the long-term effectiveness of ultrasound-guided carpal tunnel release in improving function and discomfort in patients with carpal tunnel syndrome. Retrospective review was conducted of 61 ultrasound-guided carpal tunnel release procedures performed on 46 patients (15 bilateral procedures) with clinically diagnosed carpal tunnel syndrome.

Methods: BME was classified on an ordinal scale: grade 1, faint signal immediately adjacent to the synchondrosis; grade 2, intermediate signal within the os and navicular tuberosity without extending to the navicular body; grade 3, intense signal extending to the navicular body. BME on 59 MRIs was independently graded by three radiologists.
Objectives: Vascular assessment of indeterminate renal masses (iRMs) remains a crucial element of diagnostic imaging, as the presence of blood flow within renal lesions suggests malignancy. We compared the utility of Superb Microvascular Imaging (SMI; Canon Medical Systems, Tustin, CA), a novel Doppler technique, to standard color Doppler imaging (CDI) and power Doppler imaging (PDI) for the detection of vascularity within iRMs.
Methods: Patients undergoing contrast-enhanced ultrasound (CEUS) evaluations for iRMs first underwent a renal ultrasound examination with the following modes: CDI, PDI, color Superb Microvascular Imaging (cSMI), and monochrome Superb Microvascular Imaging (mSMI), using an Aplio i800 scanner with an i8CX1 transducer (Canon Medical Systems).
The diagnosis of prostate cancer (PCa) can be challenging due to the limited performance of current diagnostic tests, including PSA, digital rectal examination and transrectal conventional US. Multiparametric MRI has improved PCa diagnosis and is recommended prior to biopsy; however, mp-MRI does miss a substantial number of PCa. Advanced US modalities include transrectal prostate elastography and contrast-enhanced US, as well as improved B-mode, micro-US and micro-Doppler techniques.
