Key result
MRI can identify both macroscopic and microscopic fat using spectral and chemical shift fat suppression techniques, enhancing the non-invasive diagnosis of intrathoracic fat-containing lesions compared to CT.
Why the study?
CT cannot demonstrate microscopic or intravoxel fat and can fail to identify microscopic fat-containing lesions, whereas MRI with fat suppression techniques can identify both macroscopic and microscopic fat.
Does MRI improve the detection and diagnosis of microscopic fat-containing thoracic lesions compared to CT in patients with intrathoracic masses?

MRI offers superior diagnostic capability over CT for intrathoracic fat-containing lesions by detecting both macroscopic and microscopic fat without ionizing radiation.
MRI may aid characterization of microscopic fat lesions missed by CT; leaves open whether it alters management or outcomes.
Intrathoracic fat-containing lesions may arise in the mediastinum, lungs, pleura, or chest wall. While CT can be helpful in the detection and diagnosis of these lesions, it can only do so if the lesions contain macroscopic fat. Furthermore, because CT cannot demonstrate microscopic or intravoxel fat, it can fail to identify and diagnose microscopic fat-containing lesions. MRI, employing spectral and chemical shift fat suppression techniques, can identify both macroscopic and microscopic fat, with resultant enhanced capability to diagnose these intrathoracic lesions non-invasively and without ionizing radiation. This paper aims to review the CT and MRI findings of fat-containing lesions of the chest and describes the fat-suppression techniques utilized in their assessment.

Hochhegger et al. (2022) conducted a review in Fat-containing thoracic lesions. Magnetic resonance imaging (MRI) vs. Computed tomography (CT) was evaluated. MRI can identify both macroscopic and microscopic fat using spectral and chemical shift fat suppression techniques, enhancing the non-invasive diagnosis of intrathoracic fat-containing lesions compared to CT.
