Super-resolution ultrasound (SRUS) can visualize intranodal non-Hodgkin lymphoma (NHL) microcirculation. This imaging technique shows promise for non-invasively differentiating B-cell and T-cell NHL subtypes.
Area of Science:
- Medical Imaging
- Oncology
- Ultrasound Technology
Background:
- Accurate subtyping of intranodal non-Hodgkin lymphoma (NHL) is essential for effective patient management.
- Distinguishing between B-cell and T-cell NHL subtypes impacts treatment strategies.
Purpose of the Study:
- To visualize the microvascular and microlymphatic circulation of intranodal NHL using super-resolution ultrasound (SRUS).
- To evaluate the diagnostic performance of SRUS imaging in predicting B-cell versus T-cell NHL subtypes.
Main Methods:
- 49 patients with intranodal NHL underwent dual-vessel SRUS imaging.
- Intravenous and intra-lymph node routes were utilized for imaging.
- Least absolute shrinkage and selection operator (LASSO) regression and leave-one-out cross-validation (LOOCV) were employed for model development and validation.
Main Results:
- The study included 40 B-cell NHL and 9 T-cell NHL cases.
- A logistic regression model using variables LDmax, LDLmin, and VCmin achieved an AUC of 0.831 for discriminating B-cell and T-cell subtypes.
- The model demonstrated significant diagnostic performance in differentiating NHL subtypes.
Conclusions:
- Dual-vessel SRUS effectively displays real-time microvascular and microlymphatic circulation in intranodal NHL.
- Quantitative analysis of SRUS imaging offers a potential non-invasive method for differentiating NHL subtypes.
