Magnetic resonance high-resolution black blood imaging for the diagnosis of intracranial arterial stenosis
Vol 36, Issue 1, 2022
Abstract
To evaluate the diagnostic value of magnetic resonance high-resolution black blood imaging in intracranial arterial stenosis, forty-six patients who underwent intracranial artery examination were selected for MRA, DSA and magnetic resonance high-resolution black blood imaging. The black blood and MRA technology results were compared with the DSA results. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of MRA were 67.85%, 66.67%, 48.27%, 65.51%, 68.96%, respectively. The high-resolution black blood imaging results were 94.11%, 95.83%, 58.62%, 96.96% and 92%, respectively, and except for accuracy, the difference between MRA and high-resolution black blood imaging was statistically significant (P<0.05). In conclusion, the magnetic resonance high-resolution blackblood technique is highly valued in diagnosing intracranial arterial stenosis.
