| Summary: | Introduction: In India, Cerebrovascular Disease (CVD) remains
to be one of the leading causes of mortality and morbidity. In
recent times, the imaging of cerebrovascular disorders has
undergone various advancements with the advent of digital
technologies. Two novel imaging modalities include Magnetic
Resonance Angiography (MRA) and Computed Tomographic
Angiography (CTA).
Aim: To assess and compare Computed Tomography Angiogram
(CTA) brain vs non contrast MR angiogram brain in evaluation
of CVD.
Materials and Methods: A cross-sectional observational study
was conducted in the Department of Radiology, Arupadai Veedu
Medical College and Hospital, Puducherry, India, from November
2020 to July 2022. All suspected cases of cerebrovascular
accidents who were above 18 years of age were screened for the
study. Finally, a total of 60 patients were recruited for the study.
Demographic parameters like age, gender and occupation were
collected. Past history of chronic illness, vitals, serum urea and
creatinine were also assessed. MRA findings including stenosis,
occlusion, and irregularity of vessels and features of stroke were
assessed and compared to the findings on CTA images. Data
was compiled and analysed using Statistical Package for the
Social Sciences (SPSS) software version 19.0.
Results: A maximum of 26 (43.3%) participants were in the age
group of 61-70 years of age and, 60% of the cases were males
and 40% of the cases were females. Out of the 60 patients, 40
(80%) had characteristics of CVD based on CTA, and 47 (78.3%)
of the individuals indicated of CVD based on MRA results. The
differences between MRA and CTA for CVD alterations were
significant (p-value<0.0001). MRA had a diagnostic efficacy
of 95% and had a sensitivity and specificity of 95.8% and
91.7% respectively, with PPV of 97.9%, and NPV of 84.6% as
compared to CTA.
Conclusion: The results of the present study demonstrate that
MRA is equally effective as CTA in diagnosing cases with CVD. |
