Special Issue Information

Dear Colleagues,

A large part of medical imaging is based on techniques involving the use of ionizing radiations. This has spurred interest to reduce the risks associated with ionizing radiations for both patients and personnel. Recent advances in hardware and software are enabling high-quality imaging with a lower radiation dose when compared to older technologies. Higher awareness has improved justification and optimization while reducing dose variations that are not dependent on the clinical situation of the patient. Moreover, dose management systems are currently able to monitor doses associated with all performed procedures, giving the opportunity to detect dose performances that need to be improved in a timely manner. In this setting, continuing education for healthcare professionals is pivotal to minimize unnecessary examinations and radiation exposure, while training radiologists and radiographers is mandatory to optimize data acquisition and reduce dose variability.

This Special Issue will focus on pertinent research papers, perspectives, and reviews informing readers about innovative approaches to radiation protection in medical imaging implemented for the benefit of patients and personnel. We welcome submissions describing how radiation protection can be seen not only as a tool for reducing risk, but also as an opportunity to improve the quality of the procedures that are carried out in imaging centers around the world. Manuscripts that cover issues about justification and optimization and technological advances in image acquisition are encouraged. Of interest are applications of artificial intelligence enabling data acquisition optimization with lower radiation dose exposure as well as radiation dose monitoring by means of dedicated software tools. Dose monitoring is particularly challenging in interventional radiology: we encourage submissions that describe technologies enabling real-time monitoring of the doses to patients as well as personnel in interventional radiology, including innovative dosimetry approaches and Internet of Things applications. Radiation protection of patients and staff is an important issue in nuclear medicine as well; therefore, manuscripts on radiation safety in diagnostic and therapeutic nuclear medicine are highly appreciated.

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. Tomography 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 1800 CHF (Swiss Francs).

Background: There is growing evidence that supports the use of chest ultrasound (CUS) versus conventional chest X-ray (CXR) in order to diagnose postoperative complications. However, data regarding its use after thoracic surgery are scarce and contradictory. The aim of this study was to conduct a systematic review to evaluate the accuracy of CUS after thoracic surgery. Methods: An electronic search in MEDLINE (via PubMed), complemented by manual searches in article references, was conducted to identify eligible studies. Results: Six studies with a total of 789 patients were included in this meta-analysis. Performing CXR decreased in up to 61.6% of cases, with the main reasons for performing CXR being massive subcutaneous emphysema or complex hydrothorax. Agreement between CUS and routine-based therapeutic options was, in some studies, up to 97%. Conclusions: The selectively postoperative use of CUS may reduce the number of routinely performed CXR. However, if CUS findings are inconclusive, further radiological examinations are obligatory. Full article

Abstract: Computer-tomography angiography (CTA) has been the gold standard imaging modality for vascular imaging due to a combination of advantageous factors including the widespread availability of computer tomography (CT) machines, the ease and speed of image acquisition, and the high sensitivity of CTA for thrombus formation. However, the large dose of radiation exposure experienced by the patient during the imaging process has long been a concern of this image acquisition method. With the widespread adoption of new imaging techniques such as magnetic resonance angiography (MRA) and contrast enhanced ultrasound (CEUS) in addition to improvements in CT image acquisition techniques including advancements in both software and hardware, a variety of imaging methodologies have recently been developed that bode well for reducing total radiation dose exposure for the patients. This review article provides an overview of current imaging techniques and strategies utilized for radiation dose reduction in vascular imaging and how recent advancements in technology and image acquisition have led to viable alternatives to CTA in a variety of patient populations.
