Pediatr Radiol 2023; 53:632-639. [PMID: 36169668 PMCID: PMC10027643 DOI: 10.1007/s00247-022-05517-1] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2022] [Revised: 07/18/2022] [Accepted: 09/06/2022] [Indexed: 10/14/2022]
Abstract
Over the last few years, fetal postmortem microfocus computed tomography (micro-CT) imaging has increased in popularity for both diagnostic and research purposes. Micro-CT imaging could be a substitute for autopsy, particularly in very early gestation fetuses for whom autopsy can be technically challenging and is often unaccepted by parents. This article provides an overview of the latest research in fetal postmortem micro-CT imaging with a focus on diagnostic accuracy, endovascular staining approaches, placental studies and the reversibility of staining. It also discusses new methods that could prove helpful for micro-CT of larger fetuses. While more research is needed, contrast-enhanced micro-CT has the potential to become a suitable alternative to fetal autopsy. Further research using this novel imaging tool could yield wider applications, such as its practise in imaging rare museum specimens.

Volumetric Tissue Imaging of Surgical Tissue Specimens Using Micro-Computed Tomography: An Emerging Digital Pathology Modality for Nondestructive, Slide-Free Microscopy-Clinical Applications of Digital Pathology in 3 Dimensions. Am J Clin Pathol 2023; 159:242-254. [PMID: 36478204 DOI: 10.1093/ajcp/aqac143] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2022] [Accepted: 10/14/2022] [Indexed: 12/14/2022] Open
Abstract
OBJECTIVES Micro-computed tomography (micro-CT) is a novel, nondestructive, slide-free digital imaging modality that enables the acquisition of high-resolution, volumetric images of intact surgical tissue specimens. The aim of this systematic mapping review is to provide a comprehensive overview of the available literature on clinical applications of micro-CT tissue imaging and to assess its relevance and readiness for pathology practice. METHODS A computerized literature search was performed in the PubMed, Scopus, Web of Science, and CENTRAL databases. To gain insight into regulatory and financial considerations for performing and examining micro-CT imaging procedures in a clinical setting, additional searches were performed in medical device databases. RESULTS Our search identified 141 scientific articles published between 2000 and 2021 that described clinical applications of micro-CT tissue imaging. The number of relevant publications is progressively increasing, with the specialties of pulmonology, cardiology, otolaryngology, and oncology being most commonly concerned. The included studies were mostly performed in pathology departments. Current micro-CT devices have already been cleared for clinical use, and a Current Procedural Terminology (CPT) code exists for reimbursement of micro-CT imaging procedures. CONCLUSIONS Micro-CT tissue imaging enables accurate volumetric measurements and evaluations of entire surgical specimens at microscopic resolution across a wide range of clinical applications.

Abstract
Ex vivo ultrasound (US) of human tissues has been used for decades on the study of the acoustic physical aspects of the US, to the study of the morphology of the organs. Using three-dimensional (3D) US, we demonstrate the possibilities to study surgical specimens from gynecological conditions. 3D images of the surgical specimen were collected and virtually segmented according to the contrast of its images, providing a 3D image of the ectopic pregnancy and its effects on the fallopian tube.

The human endosalpinx: anatomical three-dimensional study and reconstruction using confocal microtomography. Pol J Radiol 2019; 84:e281-e288. [PMID: 31482002 PMCID: PMC6717942 DOI: 10.5114/pjr.2019.86824] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2019] [Accepted: 05/07/2019] [Indexed: 12/21/2022] Open
Abstract
Purpose To evaluate in three dimensions (3D) the human endosalpinx and reconstruct its surface
along its different anatomical segments, without the injection or insertion of luminal
contrasts, using confocal microtomography (micro-CT). Material and methods 15 fallopian tubes (FT) from 14 women in reproductive age from procedures for benign
disease or sterilization were selected. The specimens were fixed in formalin and stained
with Lugol solution. Micro-CT studies were conducted on the specimens using protocols
adapted from biological studies, to acquire images to reconstruct in 3D the endosalpinx
surface. Results From these specimens, 6 presented the intra-mural segment, 14 presented the isthmus and
15 presented the ampulla and fimbria segment of the FT. The specimen presented tissue
definition, and contrast sufficient for FT endosalpinx morphological analysis and lumen
definition. The intramural portion presented initially a mucosal projection toward the
lumen, bending on its own axis, and increased numbers of projections towards the isthmic
portion, where the projections become longer more numerous. The endosalpinx becomes more
tortuous, the lumen diameter increases and the mucosal projections become more bulky in
the ampullary portion, with the projections less present on the antimesenteric side. The
infundibular portion is marked with the organized and predictable endosalpinx, the
abdominal ostium is cleared demonstrated, with the reduction of the endosalpinx volume.
The fimbria demonstrated a small relation between fringes and intratubal
endosalpinx. Conclusions Microscopic anatomy of different segments of the human FT mucosa can be analyzed and
reconstructed in 3D with histological correlation using micro-CT.
