Special Issue Information

Dear Colleagues,

Currently, abdominal ultrasound is used in various ways, including contrast-enhanced elastography and endoscopic ultrasound, and is becoming a central part of the diagnosis of abdominal diseases. However, it is also true that there are still areas of abdominal diseases that have not been fully explored. It is necessary to focus on this area to advance the use of diagnostic ultrasound. For this reason, we are launching a Special Issue to collect related papers.

In this series, we will present cases with many lessons learned regarding liver, biliary, and pancreatic tumors, which are the main abdominal diseases, with a focus on external ultrasound and endoscopic ultrasound and will organize the information obtained to provide an objective and in-depth perspective on how to prevent misdiagnosis and draw conclusions that can be immediately applied to general clinical practice. To supplement this series, we will also include a detailed description of the peritoneum, mesentery, and omentum, which are always difficult to diagnose in daily clinical practice, as well as key points in the diagnosis of these pathologies.

We welcome you to submit your research work to this Special Issue.

Dr. Hiroko Naganuma
Guest Editor

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.

Prior to the curative resection of colorectal carcinoma (CRC) or pancreatic ductal adenocarcinoma (PDAC), the exclusion of hepatic metastasis using cross-sectional imaging is mandatory. The Doppler perfusion index (DPI) of the liver is a promising method for detecting occult liver metastases, but the underlying visceral duplex sonography is critically viewed in terms of its reproducibility. The aim of this study was to investigate systematically the reproducibility of the measured variables, the calculated blood flow, and the DPI. Between February and September 2023, two examinations were performed on 80 subjects within a period of 0–30 days and at two previously defined quality levels, aligned to the German standards of the DEGUM. Correlation analyses were carried out using Pearson’s correlation coefficient (PCC) and the intraclass correlation coefficient (ICC). The diameters, blood flow, and DPI showed a high degree of agreement (PCC of 0.9 and ICC of 0.9 for AHP). Provided that a precise standard of procedure is adhered to, the Doppler examination of AHC, AHP, and PV yields very reproducible blood flows and DPI, which is a prerequisite for a comprehensive investigation of its prognostic value for the prediction of metachronous hepatic metastasis in the context of curatively treated CRC or PDAC.
