Ultrasound practice is a longstanding tradition for radiology departments, being part of the family of imaging techniques. Ultrasound is widely practiced by non-radiologists but becoming less popular within radiology. The position of ultrasound in radiology is reviewed, and a possible long-term solution to manage radiologist expectations is proposed.

A simple, novel approach for implementation of PoCUS of the oral cavity and maxillofacial complex is introduced. Relevant indications include differentiating abscess from cellulitis, detecting jaw and facial fractures, assessment of surgical complications, removing foreign bodies, and evaluating soft tissue masses.

Objectives: To determine the feasibility of pSWE for assessing liver stiffness and fibrosis in liver diseases of different etiologies.
Dermatologic ultrasound is a recent application of ultrasound for the evaluation of healthy skin and appendages and their diseases. Although the scientific literature regarding this application is still not sufficient for evidence-based guidelines, general recommendations issued by scientific societies are necessary. The EFSUMB (European Federation of Societies for Ultrasound in Medicine and Biology) steering committee for dermatologic ultrasound has developed a series of consensus position statements regarding the main fields of dermatologic ultrasound (technical requirement, normal skin and appendages, inflammatory skin diseases, tumoral skin diseases, aesthetic dermatology and practice-training requirements).

In this pilot study, we tested TPD in 15 patients diagnosed with pulmonary embolism on computed tomography pulmonary angiography. Results were mapped to the upper, middle, and lower thirds of the right lung.

The mean measurement difference between conventional US and CTA was 0.50 cm, compared with 0.

The hypothesis of this study was that that by using image fusion of subsequent ultrasound (US) with the initial unenhanced CT, ureteral stones can be precisely localized.
Conclusion: Of the 25 stones founds on unenhanced CT studies, 22 (88%) were confidently identified using US-unenhanced CT fusion within 72 hours after the initial CT scan was obtained.
Background: Staging and monitoring of patients with hidradenitis suppurativa (HS) have been traditionally based on clinical findings. However, the physical examination may show important limitations because of its poor sensitivity for differentiating between different lesion subtypes, and its low sensitivity to define the disease's activity.
Objective: To develop a consensus ultrasound (US) report that could summarize the relevant anatomical characteristics and staging of patients considering the experience of radiologists and dermatologists working on imaging of HS.
Background: Ethanolic extract of licorice root has been shown to reduce low-density lipoprotein (LDL) oxidation in atherosclerotic mice and in both hypercholesterolemic and normal lipidemic humans.
Objective: This study examined the effect of licorice-root extract on carotid intima-media thickness (CIMT) in individuals with hypercholesterolemia.
Design: Individuals with hypercholesterolemia (total cholesterol ≥6.
Objectives: To support standardization for performing dermatologic ultrasound examinations.
Methods: An international working group, called DERMUS (Dermatologic Ultrasound), was formed, composed of physicians who have been working on a regular basis and publishing in peer-reviewed articles on dermatologic ultrasound. A questionnaire on 5 critical issues about performance of the examinations was prepared and distributed by e-mail.
Purpose: To evaluate compliance with a management strategy for use in emergency department (ED) patients with suspected deep vein thrombosis (DVT) based on Wells score (WS), D-dimer concentrations, and sonographic (US) examinations.
Methods: Retrospective and prospective data on risk factors, physical examination findings, D-dimer concentrations, and US results were collected and reviewed. The prevalence of DVT for each WS category and D-dimer level was calculated.
Objectives: The purpose of this study was to determine the value of dynamic high-resolution sonography for evaluation of temporomandibular joint (TMJ) disk displacement compared to magnetic resonance imaging (MRI) with the mouth closed and during the maximal mandibular range of motion.
Methods: Dynamic high-resolution sonography with the mouth closed and during the maximal mandibular range of motion was performed on 39 consecutive patients (78 joints; 13 male and 26 female; age range, 18-77 years; mean age ± SD, 37.23 ± 16.
Background: High-variable-frequency ultrasound is used as an imaging tool for various cutaneous disorders. We utilized this tool in pachyonychia congenita (PC) patients, who typically present with plantar hyperkeratosis and often severely debilitating pain, compared to patients with epidermolytic palmoplantar keratoderma (EPPK) and mal de Meleda (MDM).
Objective: To ascertain the feasibility of ultrasound technology for the diagnosis of PC.
Plasmapheresis (PA) and low-density lipoprotein apheresis (LDL-A) were assessed in five children with homozygous familial hypercholesterolemia (HFH) previously receiving statins. LDL-A required smaller extracorporeal blood volumes. Mean HDL-cholesterol reduction post-procedure was 32% and 60% with LDL-A and PA, respectively.

US is widely used in the characterization of scrotal pathologies as a supplement to the clinical examination. Modern US equipment, precise technical performance, and knowledge of sonographic anatomy and pathology, as in any US examination, are the basis for a correct diagnosis.

Sports injuries and degenerative and inflammatory processes are the main sources of shoulder pain and functional limitations. Because of its availability, low cost, dynamic examination process, absence of radiation exposure, and ease of patient compliance, US is the preferred mode for shoulder imaging over other, more sophisticated, and expensive methods.
