Abstract

Objectives: To ascertain the diagnostic efficacy of diffusion imaging in patients with dural venous sinus thrombosis (DVST).

Study Design: Descriptive cross-sectional study.

Place and Duration of Study: A tertiary care institute of radiology and imaging, Rawalpindi, Pakistan, from Aug to Nov 2023.

Methodology: This study enrolled 100 patients who reported to a radiology and imaging center, for diagnosis of dural venous sinus thrombosis (DVST). The patients were enrolled through non-probability purposive sampling after taking informed written consent. Patients underwent diffusion imaging and data was analyzed using Statistical Package for Social Sciences (SPSS) version 26.00, where diagnostic accuracy, sensitivity and specificity was also measured.

Results: Among 100 patients, 36.00% were male and 64.00% were female. After the procedure, DVST was diagnosed in 24.00% enrolled patients. Sensitivity and specificity were 23.40% and 66.60% respectively.

Conclusion: Diffusion imaging may have exploratory roles for DVST but has low diagnostic efficiency.
