Table 1. Detection of different tumor components in gbPC-CT, gbCT, clinCT and MRI compared with histopathologic findings.
| gbPC-CT/Histo | gbCT/Histo | clinCT/Histo | MRI/Histo | |
|---|---|---|---|---|
| Fibrous strands | 15/15 | 0/15 | 0/15 | 4/15 |
| Pseudocapsule | 8/9 | 0/ 9 | 0/9 | 6/9 |
| Calcification | 9/17 | 17/17 | 4/17 | * |
| Microbleeding | 10/11 | 0/11 | 0/ 11 | * |
| Diffuse hemorrhage | 5/5 | 3/5 | 2/5 | 5°/5 |
| Hyalinization | 6/8 | 6/8 | 2/8 | 6/8 |
| Necrosis | 2/3 | 0/3 | 0/3 | 1/3 |
Note. – detection in the different modalities was determined according to histopathological findings.
*Small susceptibility artifacts in susceptibility weighted images (SWI) in 17 samples.
°large hypointense areas.
gbPC-CT – grating-based phase-contrast computed tomography; gbCT – grating-based computed tomography; clinCT – clinical computed tomography; MRI – magnetic resonance imaging; Histo – histological findings.
