"A definite diagnosis is made by measuring intracompartmental presssures (ICP), as in acute compartment syndrome. However, there is little evidence and no agreed standard to diagnose CECS (c.2012) on the basis of compartment pressures 6."

"The exact prevalence is not known since sufferers may modify the way they exercise and therefore never present. CECS can present at any age and any level of physical activity 1. There is no sex predilection. CECS occurs bilaterally in 70-80% 2."
"The pathophysiological mechanism is not entirely understood. During physical activity, muscle fibres are recruited and blood flow increases, causing expansion. If fascia restricts this expansion, the pressure within a compartment increases and reduced blood flow with resultant ischaemia and pain. There is also increased interstitial fluid. This process is independent of vascular patency 3. The increased interstitial fluid will give rise to localised increased T1 and T2 relaxation times 4. A mechanism independent of ischaemia has also been supported by findings in early MR studies 5."
"Additional studies are needed to delineate the exact role of MRI in the workup of CECS, but MRI can certainly be used as a problem-solving tool in patients refusing or have contraindications to compartment pressure measurement, or when there is diagnostic confusion (e.g. coexisting pathologies)."
"protocol: it is necessary to perform MRI immediately after exercise-inducing pain; there are out-of-scanner and in-scanner exercise protocols 12"
