Special Issue Information

Dear Colleagues,

After a successful first edition of the Special Issue “Current Challenges and Perspectives of Ultrasound” (Diagnostics | Special Issue: Current Challenges and Perspectives of Ultrasound (mdpi.com)) , we are pleased to announce a second edition.

Innovative ultrasound techniques play an important role in the diagnostic and therapeutic management of benign and malignant diseases of almost all organ systems. Ultrasound techniques for adult and pediatric patients include contrast-enhanced ultrasound (CEUS), strain imaging, shear wave elastography, fusion imaging, and the golden standard of “endoscopic ultrasound (EUS)”, which combines endoscopy and ultrasound. Ultrasound-guided interventions are of the utmost importance due to their advantages, including real-time guidance, availability, and high resolution. Controversies in applying such ultrasound technologies and educational issues surrounding them are important. In addition, artificial intelligence has been already implemented into ultrasound technology in many circumstances.

The present Special Issue  will include the latest advancements of the topics mentioned above, presented as research articles, literature reviews, state-of-the-art papers, educational topics, and meta-analyses, which are important reading for experienced physicians, beginners, and students.

We hope that the published papers will enhance scientific discussion and collaboration.

Prof. Dr. Christoph Frank Dietrich

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Diagnostics is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Background/Objectives: Anal incontinence is linked to pelvic floor dysfunction. Diagnosis involves assessing both the function and structure of the anorectal unit. Although transperineal ultrasound has gained attention as a less invasive option, its effectiveness as a diagnostic tool for evaluating the relationship between structure and function is still debated. This study aimed to explore the relationship between quantitative measurements of anal sphincter and pelvic floor structures as well as the subjective symptoms and objective assessments of sphincter function regarding anal incontinence. Methods: 50 women with pelvic floor dysfunction were recruited for the study. The severity of anal incontinence was assessed using the CACP score. Ultrasound imaging was employed to measure anal sphincter area, while sphincter pressures were evaluated through manometry. The relationships between variables were analyzed using Pearson’s and Spearman’s correlation tests. Results: The mean anal sphincter area was 5.51 cm2 at rest and 4.06 cm2 during maximal contraction. Resting anal sphincter pressure had an average of 46.29 mmHg, and contraction pressure averaged 103.25 mmHg. No significant correlation was found between the anal sphincter area and pressure at rest (r = 0.018) or during contraction (r = −0.210). However, a moderate correlation was observed between the change in sphincter pressure and area during contraction (r = 0.312). The CACP score showed no significant correlation with the sphincter area at rest (r = −0.084) but was weakly correlated during contraction (r = −0.270). Conclusions: Conventional diagnostic tools for evaluating anal incontinence can be uncomfortable and are not always readily available. Perineal sonography presents a promising, less invasive alternative for dynamic assessment of the anal sphincter. Full article
