Abstract

A pulse sequence procedure for producing oblique magnetic resonance images is described. Using this procedure we present a new, accurate method to obtain true short axis views and true long axis views (both parallel and perpendicular to the septal plane) of the heart. The method is accurate regardless of the orientation of patient's heart. The method does not require the patient to be rotated, nor otherwise moved, and does not require any additional hardware. The method is experimentally verified with both human and phantom studies. The phantom study indicates accuracy of approximately 1° with a commerical scanner that reports angular measurements to a precision of 1°. Application of the short axis views to measurement of left ventricular volume, and possible advantages of Gauss–Legendre integration for this measurement are discussed. Finally, multiphase oblique cardiac images are presented.
