Spectrum of aortic diseases in adults using 128 slice CT angiography
Journal Title: Medpulse International Journal of Radiology - Year 2018, Vol 7, Issue 1
Abstract
Background: Aortic pathology is often more challenging to understand and correctly diagnose.128-slice CT angiography has good temporal resolution, high scanning speed as well as low radiation dose thus become a useful first-line imaging modality to accurately evaluate the entire spectrum of aortic diseases. Aim: To study the spectrum of aortic diseases in adults using 128-slice CT angiography. Material and Methods: CT angiography was performed in 50, aged more than 14 yrs, patients presenting with sign and symptoms of aortic diseases or incidental detection of aortic disease in asymptomatic patients.Image processing and data analysis was performed using Intellispace portal software. 2D reconstruction was performed by curved multiplanar reformations (MPR) and Maximum intensity projection (MIP).For 3 dimensional reformatting of complex anatomy, the volume rendering technique was used. Results: Out of 50 patients, 13 (26%) were of congenital category and 37 (74%) were from acquired category.13 patients (26%) had aortic dissection. Out of these, 5 patients (38.5%) had Stanford type A dissection (involvement of ascending aorta) and one patient (61.5%) had Stanford Type B dissection.16 patients (32%) had aortic aneurysms. 93.25% patients had true aneurysm, while 6.75% patients had false aneurysm. 87.5% patients (14 out of 16) had single aneurysm. Conclusion: CT angiography is one stop shop for both intra and extraluminal aortic pathologies. 128-slice CT scanner generates better quality images with minimum amount of radiation as compared to previous generation CT.
