Objective. To evaluate the diagnostic value of low-dose 256-slice CT angiography (CTA), MR angiography (MRA), and three dimensional-digital subtraction angiography (3D-DSA) in cerebral aneurysms. Methods. CTA, MRA, and 3D-DSA were performed in all enrolled patients to explore the diagnostic significance of the three different examinations. Results. There were 92 aneurysms confirmed during DSA and surgery in 79 patients. The diagnostic coincidence rates of DSA, CTA, and MRA were 96.7%, 89.1%, and 86%, respectively. The diagnostic coincidence rates of CTA and MRA were lower than those of DSA. The detection rate of CTA for aneurysms less than 3 mm in diameter was higher than that of MRA. Conclusion. CTA, DSA, and MRA have their own advantages and disadvantages in the diagnosis of cerebral aneurysms. They all have the diagnostic value for aneurysms.

Cavernous Fistula

Introduction: CT angiography (CTA) is the initial modality for diagnosing theCarotid Cavernous Fistula (CCF), identifying the type of CCF, measuring thediameter of the fistula and the diameter of the internal carotid artery (ICA) pre andpost fistula, and then confirmed by Digital Subtraction Angiography (DSA) as thegold standard. CTA is expected to provide more information to improve theaccuracy of CCF diagnosis to benefit therapy and prevent complications. Thisstudy aimed to determine the diagnostic value of CTA in CCF patients in Dr.Soetomo General Hospital Surabaya, using the DSA as a gold standard. Methods:An observational retrospective study of CCF patients met the inclusion andexclusion criteria and underwent CTA and DSA examinations at the RadiologyInstallation of Dr. Soetomo General Hospital, Surabaya, from January 2016 toJuly 2020. Results: In the comparison of types of CCF CTA to DSA, the directgroup was 53.8% and 57.7%, respectively, while the indirect group was 46.1% and42.3% with a very strong correlation (κ = 0.922; p = 0.000), sensitivity was 93.3%,specificity was 100 %, PPV of 100%, NPV of 91.7% and accuracy of 96.15%. Directtype evaluation on the DSA showed a large picture of the fistula diameter; the ICApre fistula's size was enlarged; therefore, the ICA post fistula diameter wasreduced or absent. There was a strong correlation of fistula diametermeasurement results between CTA and DSA (r = 0.695, p = 0.006).Conclusion: CTA has a similarity rate of 92.2% with DSA in identifying the typeof CCF. The accuracy value of CTA is close to DSA in fistula diametermeasurements.

Measurement Results

Background: CT angiography (CTA) is the initial modality for diagnosing the Carotid Cavernous Fistula (CCF), identifying the type of CCF, measuring the diameter of the fistula and the diameter of the internal carotid artery (ICA) pre and post fistula, and then confirmed by Digital Subtraction Angiography (DSA) as the gold standard. CTA is expected to provide more information to improve the accuracy of CCF diagnosis to benefit therapy and prevent complications. This study aimed to determine the diagnostic value of CTA in CCF patients in Dr. Soetomo General Hospital Surabaya, using the DSA as a gold standard. Methods: An observational retrospective study of CCF patients met the inclusion and exclusion criteria and underwent CTA and DSA examinations at the Radiology Installation of Dr. Soetomo General Hospital, Surabaya, from January 2016 to July 2020. Results: In the comparison of types of CCF CTA to DSA, the direct group was 53.8% and 57.7%, respectively, while the indirect group was 46.1% and 42.3% with a very strong correlation (κ = 0.922; p = 0.000), sensitivity was 93.3%, specificity was 100 %, PPV of 100%, NPV of 91.7% and accuracy of 96.15%. Direct type evaluation on the DSA showed a large picture of the fistula diameter; the ICA pre fistula's size was enlarged; therefore, the ICA post fistula diameter was reduced or absent. There was a strong correlation of fistula diameter measurement results between CTA and DSA (r = 0.695, p = 0.006). Conclusion: CTA has a similarity rate of 92.2% with DSA in identifying the type of CCF. The accuracy value of CTA is close to DSA in fistula diameter measurements.
