MRI of the pulmonary veins: comparison between 3D MR angiography and T1-weighted spin echo.

摘要: OBJECTIVE The purpose was to determine the ability of three-dimensional (3D) magnetic resonance (MR) angiography depict normal pulmonary veins in comparison with spin-echo MR imaging. MATERIALS AND METHODS imaging 40 patients cardiovascular disease were reviewed. Patients known venous abnormalities excluded. Using a standard GE 1.5-T magnet, axial T1-weighted 5-mm-thick contiguous slices and 3D (contiguous slice thickness 2.5-3.5 mm, 20-30 c.c. gadolinium bolus at 1-1.5 c.c./sec, 32-43-second breath-hold, coronal sagittal plane acquisition) evaluated retrospectively on separate occasions by two experienced radiologists. Multiplanar projection used for identification veins. Each lung considered have drainage veins: superior vein an inferior vein. Identification made visualizing connection left atrium. RESULTS 143 (87.5% +/-5.2) identified level atrium images, 157 (98.1% +/-1.9) (p<0.01). Overall we T -weighted 36 right upper, 38 lower, 27 lower By angiography, 39 All four detected 22 (55%) 37 (92.5%) (chi = 3.81, p<0.05). CONCLUSION A significant difference is demonstrated between identifying provides complete view anatomy could be valuable tool assessment abnormal drainage.
