  "summary": "This article reviews and technically assesses ultrasonic cerebral tomosphygmography (UCTS/\"encephaloscan\") and argues it can help objectively diagnose electrohypersensitivity (EHS) and multiple chemical sensitivity (MCS). The abstract states that UCTS, combined with transcranial Doppler ultrasonography and peripheral biomarkers, has been shown to enable objective diagnosis and that the author independently confirms its clinical interest. It also suggests repeated UCTS may support therapeutic follow-up, noting CT/MRI are often not contributive or poorly tolerated in these patients.",
  "key_points": [
    "UCTS is presented as an ultrasound-based pulsatile echoencephalography technique for functional and anatomical brain imaging.",
    "The paper distinguishes UCTS from transcranial Doppler ultrasonography, emphasizing UCTS measures tissue pulsations rather than blood-flow velocity.",
    "The abstract claims recent work supports objective diagnosis of EHS and MCS using UCTS alongside TDU and blood/urine biomarkers.",
    "The author states they independently confirm the clinical interest of UCTS for diagnosing EHS and MCS.",
    "Repeated UCTS is proposed as a tool for objective assessment of therapeutic follow-up in EHS/MCS.",
    "The abstract asserts CT and MRI are usually not contributive for diagnosis and may be poorly tolerated by these patients."
