"The combined conduit score (CCS) is a grading scheme for the assessment of the degree of transverse-sigmoid sinus stenosis in the setting of idiopathic intracranial hypertension. The score was initially developed for ATECO MR venography 1."
"Assessment is performed using maximum intensity projection (MIP) reconstructions from gadolinium-enhanced MRV images, as time-of-flight artifacts overestimate stenosis. The initial projections described were RAO, LAO and rotational cine loop MIPs."
"the ACCS study by Kelly et al. in 2013 suggested all patients with transverse-sigmoid stenosis on MRV should undergo fundoscopy to assess for papilloedema 2"
"the sum of the right and left provides the CCS and thus ranges from 0-8, and is often expressed as a sum (e.g. 3 + 2)"
