Instructions: Obtain all images at resting lung volume:

Series 1; rapid coronal scout through chest

Series 2: T1 weighted images (parameters are actually proton density weighted). If blood supression is not available, use spin echo T1 weighted image, with superior/ inferior sat pulses.

Series 3: T2 weighted images with fat suppresion. If blood suppression is not available, use fat suppressed fast spin echo T2 with echo train length 8-16, and superior/ inferior sat pulses.

Series 4: axial cine images (for LA masses). Alternatively, run in short axis

Series 5: pre/ post gad. If an "infarct" sequence is not available, run series 5-alt

Series 5-alt: segmented k-space sequence with fat suppression. 1 slice per breath-hold. Pre and post gadolinium.
