Special Issue Information

Dear Colleagues,

Over the last decade, artificial intelligence (AI) has become a popular research topic in medicine, aiming at improving health care service quality and efficiency for individuals and populations. Simultaneously, the roles of the medical specialties, medical radiation science, radiology and radiation oncology have also become more important, but their existing workforces appear unable to match the increased demand. Hence, various AI-based solutions developed by multi-disciplinary teams of computer scientists and engineers, radiologists, radiographers, radiation oncologists, radiation therapists, medical physicists and dosimetrists have emerged to address this issue with reported performances similar to or even better than gold standards. Examples of these solutions include automatic image segmentation, computer-aided diagnosis, automated structured reporting, radiation dose optimization, clinical decision support and image quality enhancement. However, these promising results were mainly based on retrospective studies and/or those with relatively small sample sizes. Also, ethical issues in AI in medical radiation science, radiology and radiation oncology, e.g., automation bias, commission errors, responsibility for medical errors, etc., have been raised by influential bodies.

This Special Issue aims to collect medical radiation science, radiology or radiation oncology AI research findings and/or literature review papers, focusing on artificial intelligence in medical radiation science, radiology and radiation oncology that is advancing AI research in these fields.

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. Multimodal Technologies and Interaction is an international peer-reviewed open access monthly 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 1600 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.

[Background] In computed tomography (CT) for intracranial hemorrhage (ICH), the various window settings and the continuity of slices are critical factors for accurate diagnosis. However, traditional convolutional neural networks typically accept only single-slice images. Since ICH lesions often extend across multiple slices, using only single-slice images may result in reduced diagnostic accuracy by neglecting spatial continuity. Our approach addresses this limitation by integrating multi-slice information through a 9-channel pseudo-color map. To address this limitation, we explored the use of a 9-channel pseudo-color map for the discrimination of ICH in CT. [Method] A total of 21,744 cases (normal controls: 12,862; abnormal cases: 8882) from an open dataset were utilized for model training and validation. Abnormal cases included a variety of ICHs. The 9-channel pseudo-color map was generated by combining three different window settings with three continuous slices. ResNeXt50-32x4d architecture with five-fold cross-validation used. A total of 956 clinical cases were used for model testing. [Result] A total of 558,738 images were included in the model training process. The optimal model performance metrics were as follows: accuracy: 95.92%, sensitivity: 96.37%, and specificity: 95.24%. The average processing time for each case was recorded as 3.29 s. [Conclusions] The 9-channel pseudo-color map demonstrates high accuracy in the discrimination of ICH in CT images using deep learning methodologies. Full article
