CT - Dual-energy analysis
Which medications should be used with extreme caution in patients with symptomatic myocardial bridge?
Mere vasodilators such as nitrates and nitroglycerin.
What are management strategies for a symptomatic myocardial bridge?
There are no clear recommendations, according to expert opinions treatment options range from risk factor modifications over pharmacological treatment with beta-blockers and/or calcium channel blockers to surgical approaches including myotomy and bypass surgery.
MonoE at 40 keV and 80 keV
virtual monoenergetic images, synthesised at a level of 40 and 80 keV
-
reconstructions in a soft tissue algorithm with the following window settings:
monoE 80: C:800 W:2000
monoE 80: C:400 W:1000
Conventional + MonoE 40 overlay
-
conventional images, reconstructed with a standard soft tissue filter and supplemented with a colour-coded MonoE 40 overlay ranging from -600 to 1400 (C:400 W:2000)
Conventional + MonoE 80 overlay
conventional images, reconstructed with a standard soft tissue filter and supplemented with a colour-coded MonoE 80 overlay ranging from -100 to 900 (C:400 W:1000)
this setting can be also used to illustrate calcium but is less ideal for depicting spotty calcification
