Nail disorders are frequently a challenge to diagnose correctly only based on clinical findings. Moreover, biopsies may leave scars due to damage to the nail matrix. Currently, high-frequency ultrasound (HFUS) with probes >15 MHz is the first-choice imaging technique to study the nail. Compared with other imaging tests such as computed tomography and magnetic resonance imaging, HFUS has the advantage of high-resolution imaging of the nail apparatus without exposure to radiation, contrast media, and the risk of claustrophobia of these other expensive imaging methods. Notably, the axial spatial resolution of HFUS is higher than computed tomography and magnetic resonance imaging; therefore, it can better discriminate the anatomical alterations. Our objective is to review the main applications of HFUS of the nail through literature analysis and illustration of cases of the most frequent pathologies found in our experience, exemplifying why, how, and when HFUS could help diagnose nail diseases.

Ultrasound is an imaging technique that can provide critical anatomical information about malignant skin tumors that cannot be deducted by clinical examination, dermoscopy, or even biopsy. This data can support detecting and assessing the extent of the primary tumor and its differential diagnosis, surgical planning, and locoregional staging. Moreover, this non-invasive technique can help to follow-up and detect recurrences. This review aims to address the most common indications for ultrasound in skin oncology and provide a comprehensive guide to the grayscale and color-Doppler findings in cutaneous melanoma, squamous cell carcinoma, basal cell carcinoma, and other cutaneous malignant tumors.

Benign cutaneous tumors are commonly seen in daily practice. Most of these lesions are diagnosed based on clinical appearance, but in some cases, clinical findings are nonspecific. A diagnostic imaging exam is indicated to provide additional information, and the first choice for studying dermatologic lesions is a high-frequency color Doppler ultrasound, a noninvasive technique that can play a relevant role in all cases and give important anatomical information for final diagnosis and proper clinical management. This article aims to show the most common benign skin lesions emphasizing clinical-sonographic correlation and familiarizing radiologists with the sonographic appearance of the key benign cutaneous tumors.

Ultrasound in aesthetics presents multiple applications in several areas, including diagnosing fillers and non-fillers complications, the performance of ultrasound-guided injections in real-time, and identifying the most common types of cosmetic fillers. Furthermore, this application of ultrasound in aesthetics has become a must for managing aesthetic patients because, to date, this modality is the one that provides the higher resolution among imaging techniques, detailed anatomical information, and blood flow detection, besides showing worldwide availability. This paper aims to review the current applications of ultrasound in aesthetics based on publications from scientific literature and the authors' experience.

Dermatologic ultrasound has grown exponentially during the last decades and has passed from the experimental phase to the routine daily practice in multiple countries. The performance of this imaging technique requires color Doppler ultrasound devices working with high-frequency probes, a trained operator on imaging and dermatologic conditions, and the performance of standardized protocols for obtaining the anatomical data properly. In this review, we analyze the ultrasonographic anatomy of the skin, hair, and nails, the technical requirements and considerations, the guidelines, and the recommended protocols, and provide the best tips for practicing this type of examination confidently.

Inflammatory cutaneous diseases can be challenging to diagnose and manage. Nowadays, the anatomical information provided by ultrasound is critical for detecting subclinical alterations and assessing the severity and activity of these conditions. Many of these entities can be clinically observed in dermatology and other specialties, such as rheumatology, plastic surgery, ophthalmology, and otolaryngology, among others. We review the ultrasonographic patterns of the most common inflammatory cutaneous conditions. In several cases, such as hidradenitis suppurativa, acne, and morphea, there are ultrasonographic staging systems of severity or activity that are pivotal in the management of these diseases. The early ultrasonographic diagnosis of these entities implies a proper management of the patients and, therefore, improve their quality of life. Thus, knowledge of the current use of ultrasound in this field seems essential.

Diversity, equity, and inclusion (DEI) are fundamental to a just healthcare system, yet academic radiology continues to grapple with the underrepresentation of women and underrepresented minorities (URMs). This study investigates demographic disparities within academic radiology and proposes strategies to enhance DEI. Through analysis of demographic data and a review of successful DEI initiatives, I identified a severe underrepresentation of URMs and women throughout every stage of the radiology pipeline. Challenges such as implicit bias, financial barriers, and lack of mentorship contribute to this disparity. However, promising initiatives like the Radiology Leadership Institute and the Association of University Radiologists Mentorship Program offer examples of progress in diversifying the field. To achieve true DEI in academic radiology, a multifaceted approach is essential, encompassing early outreach, financial aid, mentorship, inclusive recruitment, and a commitment to fostering a welcoming environment. Continuous evaluation and adaptation of these initiatives will pave the way for a more equitable and inclusive future in radiology.
