"The right dome of diaphragm is usually 2cm higher than the left dome 11."
"medial lumbocostal arch (medial arcuate ligament): a tendinous arch from the superior anterior thickened psoas major fascia; continuous medially with the ipsilateral crus; attached to the L1/L2 anterolateral vertebral body, and the anterior aspect of the L1 transverse process"
"lateral lumbocostal arch (lateral arcuate ligament): covers quadratus lumborum muscle; attaches medially to the L1 transverse process and attaches laterally to the tip of the 12th rib; this may be discontinuous on CT in up to 11% of people and hence may mimic diaphragmatic rupture 8"
"The medial margins of the two crura pass forwards and medially. They meet in the midline to form an arch in front of the aorta called the median arcuate ligament."
"Innervation is mainly via the bilateral phrenic nerves (C3-C5) which pierces the diaphragm and on its inferior surface divide into several radiating branches to supply it."
"each phrenic nerve (C3-C5) provides the sole motor supply to the ipsilateral hemidiaphragm 9,10"
"carries their own nerve supply from these levels explaining the C3-C5 origin of the phrenic nerve"
"high resolution T2W TSE/SSFSE (HASTE/SS‑FSE) in axial and coronal planes are widely regarded as the key sequences for depicting the thin muscular sheet, defects, and herniated contents"
