Magnetic Resonance Imaging Protocol Optimization for Detection of Endometriotic Lesions

transmit-receive extremity RF coil; previous medical history and investigation indicated compartment syndrome was suspected in the anterior tibialis region. High resolution T1-weighted SPGR images were acquired prior to functional imaging. Mid-calf axial BOLD images were acquired using a Gradient Echo sequence with an EPI readout (∝=70o, TE/TR=35/250ms, FOV 24cm, 64x64 matrix). 3072 contiguous images were acquired over 12.8 minutes at a rate of 4 per second (4Hz). Data acquisition was performed prior to and immediately following 30 minutes of intense exercise. BOLD data obtained from muscle regions of interest (ROIs; soleus, gastrocnemius, anterior tibialis) were spatially aligned with anatomical slices and Fourier transformed into frequency spectra using in-house programs written in Matlab (The Mathworks, Natick MA).
