Special Issue Information

Dear Colleagues,

Medical imaging is one of the cornerstones of modern medical diagnostics. It originated in the field of radiology, and includes various technologies such as X-ray imaging, radionuclide imaging, ultrasound imaging, magnetic resonance imaging, optical imaging, mass spectrometry imaging, bioelectric/magnetic imaging, and electron microscopy imaging. In recent decades, with the rapid development of hyperspectral cameras and artificial intelligence, hyperspectral imaging (HSI) has become an emerging and promising medical auxiliary diagnostic technology.

Although medical imaging technology obtains a large amount of information that the human eye cannot perceive, it is still extremely challenging to effectively utilize information for auxiliary diagnosis and disease treatment. Some of the challenges include low image spatial or spectral resolution caused by imaging device limitations, small sample issues caused by missing clinical sample annotations, difficulty in extracting diagnostic information, class imbalance learning, multimodal learning, domain adaptation, etc.

Therefore, this Special Issue aims to collate papers that address the aforementioned challenges, and highlights the recent research findings and developments in the field of medical image classification and segmentation. We also welcome submissions of manuscripts on aspects closely related to the scope of this Special Issue (e.g., image registration, image reconstruction, feature extraction, feature selection, etc.).

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. Journal of Imaging 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 1800 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.

This study aims to evaluate non-invasive PET quantification methods for (R)-[11C]PK11195 uptake measurement in multiple sclerosis (MS) patients and healthy controls (HC) in comparison with arterial input function (AIF) using dynamic (R)-[11C]PK11195 PET and magnetic resonance images. The total volume of distribution (VT) and distribution volume ratio (DVR) were measured in the gray matter, white matter, caudate nucleus, putamen, pallidum, thalamus, cerebellum, and brainstem using AIF, the image-derived input function (IDIF) from the carotid arteries, and pseudo-reference regions from supervised clustering analysis (SVCA). Uptake differences between MS and HC groups were tested using statistical tests adjusted for age and sex, and correlations between the results from the different quantification methods were also analyzed. Significant DVR differences were observed in the gray matter, white matter, putamen, pallidum, thalamus, and brainstem of MS patients when compared to the HC group. Also, strong correlations were found in DVR values between non-invasive methods and AIF (0.928 for IDIF and 0.975 for SVCA, p < 0.0001). On the other hand, (R)-[11C]PK11195 uptake could not be differentiated between MS patients and HC using VT values, and a weak correlation (0.356, p < 0.0001) was found between VTAIF and VTIDIF. Our study shows that the best alternative for AIF is using SVCA for reference region modeling, in addition to a cautious and appropriate methodology. Full article
