Background And Purpose: The total calcification score (TCS) is a visual rating scale to measure primary familial brain calcification (PFBC)-related calcification severity on CT. We investigated the inter- and intrarater agreement of a modified TCS.
Materials And Methods: Patients aged ≥18 years with PFBC or Fahr syndrome who visited the outpatient clinic of a Dutch academic hospital were included.
Background And Purpose: Carotid siphon calcification might contribute to the high prevalence of cerebrovascular disease in pseudoxanthoma elasticum through increased arterial flow pulsatility. This study aimed to compare intracranial artery flow pulsatility, brain volumes, and small-vessel disease markers between patients with pseudoxanthoma elasticum and controls and the association between arterial calcification and pulsatility in pseudoxanthoma elasticum.
Materials And Methods: Fifty patients with pseudoxanthoma elasticum and 40 age- and sex-matched controls underwent 3T MR imaging, including 2D phase-contrast acquisitions for flow pulsatility in the assessment of ICA and MCA and FLAIR acquisitions for brain volumes, white matter lesions, and infarctions.
