Brief summary
The frailty syndrome is important to consider in perioperative cardiac assistance. One of its components is the patient's sarcopenia. This can be assessed by measuring the size of the psoas muscle. For this purpose, one of the most studied measures seems to be the measurement of the Psoas Index. This is a contouring of the psoas muscle, performed on an axial section of a CT scan, at the level of the L4 vertebra, which is then matched to the body surface. However, there is no standardization of measurements and volume acquisitions, and different image processing is also described. A radiological evaluation of the psoas could overcome this difficulty and provide a rapid and available screening tool for sarcopenia.
