Background:
Hematopathology is rapidly advancing. Combining structural, molecular, and dynamic analyses enables a deeper understanding of immune reactions and malignant lymphomas.
Materials And Methods:
Three-dimensional (3D) imaging uses fluorescence-stained tissue sections with confocal microscopy. Four-dimensional (4D) live tissue slices allow real-time visualization of immune cell movement. Drugs can be tested directly on fresh samples.
Results:
Three-dimensional images show key immune cell types; 4D imaging reveals cell-cell interactions. Nivolumab, for example, prolonged T cell contact with Hodgkin cells.
Conclusion:
Four-dimensional technology improves early disease detection, treatment monitoring, and drug development, bridging between molecular findings and clinical applications.

Imaging Studies III: Computed Tomography
Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
