Ultrasound Image Modality - Assignment Example Color flow imaging uses high-intensity pulse wavelengths that are 3 – 4 times longer than B-mode image pulses, with an equivalent spatial resolution decrease. In previous clinical trials, grayscale version of three-dimensional displays has been recreated to determine mitral regurgitation. Regurgitant mitral flow jets could hardly be differentiated from adjoining structures of the heart. A regurgitant mitral flow displayed in the color-coded three-dimensional image was developed but eventually proved to be ineffective because the display failed to incorporate cardiac structures. Failure of the regurgitant flow to supply spatial information, jet origin and its course of action led to the reconstruction of a more enhanced colored 3D regurgitant jet by a transesophageal approach with Doppler color flow mapping that displayed a combination of grayscale and color flow information. OBJECTIVE:Â  To reveal the possibility of three-dimensional recreation of regurgitant mitral flow jets using the new method of color programmed digitized statistics obtained through transesophageal echocardiography (TEE). METHOD:Â  46 patients with detected mitral regurgitation on a prior transthoracic study and undergoing transesophageal echocardiography were evaluated. Patients with atrial fibrillation were not excluded from standard procedures. To measure regurgitant flow in 3D, a commercial ultrasound imaging system with a TEE probe was used. An alternation approach of data collection was employed for two-dimensional color flow images at 3-degree spaces above 180 degrees. Three-dimensional color flow jets were showed alongside grayscale information of the surrounding structures of the heart.
