Key result
Multimodal 3D imaging clarifies normal pericardial recesses to prevent misidentifying them as pathology.
Why the study?
Normal human pericardial structures as depicted by CT and MR imaging require detailed anatomical characterization and correlation with cadaveric sections.
This anatomical study correlates in-vivo CT and MR imaging of the pericardium with ex-vivo cadaveric reconstructions to improve understanding of normal pericardial structures.
Answers are grounded in this paper and cite their sources.
Aids precise pericardial recess identification on CT/MR; extends cadaveric correlations but leaves open prospective clinical validation.
The pericardial cavity, sinuses, and recesses are frequently depicted on Computed Tomography (CT) and Magnetic Resonance (MR). We here review the normal human pericardial structures as provided by MR imaging of young, healthy subject and CT scans acquired after iatrogenic coronary dissection. We compared such radiological information with cadaveric axial and sagittal sections of the human body provided by the Visible Human Server (VHS), Ecole Polytechnique Federale de Lousanne (EPFL), Switzerland.

Mantini et al. (2021) conducted a review in Normal pericardial anatomy (n=6). Anatomical imaging (CT, MRI, 3D reconstruction) was evaluated. Detailed anatomical comparison of in-vivo CT and MRI with ex-vivo 3D reconstructions clarifies the normal appearance of pericardial sinuses and recesses to help differentiate them from pathological findings.
