Case: Detection of morphology of aortic valve by cardiac MDCT

posted by Sandra Simon Halliburton, Ph.D. | Feb 18, 2010

History
49-year old male referred to CT for evaluation of aortic valve. Besides asthma and history of colonoscopy, the patient was in good health. Physical examination revealed a heart murmur. The baseline echocardiogram reported normal tricuspid aortic root with moderate aortic regurgitation (AI) and EF of 60 %.

Question
Detection of morphology of aortic root, and severity of aortic regurgitation for surgical planning.

Diagnosis/Differential diagnosis
Aortic valve disorder – moderately severe AI

Findings
The 3D and 4D assessment of aortic root demonstrates a bicuspid aortic valve with partial fusion between non- and right coronary cusps. There is a mild prolapse of the partially fused non- and right cusp with incomplete diastolic coaptation. The area of the diastolic opening measures 0.23 cm². The diastolic opening formed by thick raphe is likely associated with severe aortic insufficiency. The absence of aortic valve calcification is noted.

Comments
Cardiac MDCT proves to be reliable source for detection of morphology of aortic valve. 4D images of phases between 0-90 % enable functional assessment of aortic valve and identification of degree of severity of valvular disorders.

Effect of dual-source cardiac computed tomography on patient radiation dose in a clinical setting: comparison to single-source imaging

posted by Sandra Simon Halliburton, Ph.D. | Jul 17, 2009

Background Dual-source computed tomography (DSCT) was introduced with significant hardware and software changes compared with single-source CT (SSCT), resulting in improved temporal resolution (83 ms) and the potential for improved image quality. The effect of these changes on radiation dose requirements for coronary CT angiography in clinical practice has not been … Read more

Clinical Feasibility of Arterial Phase Dual Energy Computed Tomography Imaging For Endovascular Aortic Aneurysm Repair

posted by Sandra Simon Halliburton, Ph.D. | Jun 18, 2009

Abstract Objective: Triple phase (non-contrast, arterial, venous) single energy CT (SECT) scans are often used to monitor patients after endovascular thoracoabdominal aortic aneurysm repair. We investigated the feasibility of replacing non-contrast and arterial phase SECT scans with a single arterial phase dual energy CT (DECT) scan and generating virtual non-contrast images. Methods: … Read more
