TES HT100 Klinikai Validáció Enyhe Fejsérülés vagy Neurológiai Tünetekkel Rendelkező Beteg Agysérülés Szűrésére (TESCO)
TES HT100 Klinikai Eredmények - A TES HT100 Temnográf klinikai validációja az agysérülés szűrésére enyhe fejsérüléssel vagy gyanús neurológiai tünetekkel rendelkező betegeknél (TESCO)
The goal of this clinical study is to evaluate how accurately and safely the TES HT100 device can identify intracranial abnormalities in adult emergency department patients with mild head trauma or neurological symptoms that are not related to trauma and are not immediately life-threatening. The main questions it aims to answer are:
- How well does TES HT100 identify patients with intracranial abnormalities compared with head CT, the reference standard?
- Is TES HT100 safe to use in this patient population?
- Could TES HT100 help improve patient triage and use of hospital resources in the emergency setting?
Researchers will compare the result of TES HT100 with the head CT report.
Participants will:
- Be enrolled if they are adults presenting to the emergency department with mild head trauma or selected neurological symptoms
- Undergo standard clinical assessment and head CT according to usual care
- Have an additional TES HT100 examination lasting about 5 minutes, performed by trained personnel
- Be assessed for device performance and any adverse events related to use of the device

Részletes leírás
This is a prospective, multicenter, open-label clinical investigation evaluating the TES HT100 as a non-invasive adjunctive screening device for detection of intracranial abnormalities in adult Emergency Department patients. The study is being conducted in three centers in Italy and Poland.
TES HT100 is intended for non-invasive detection of endocerebral lesions. The device used in this investigation is TES HT model 100, equipped with software version 1.3 or later and firmware version 1.4 or later, in the same configuration planned for commercialization. The system uses non-ionizing, ultra-low-power electromagnetic waves in the 500-6500 MHz frequency range and provides a binary result indicating the presence or absence of intracranial abnormality. The examination is brief, with an overall duration of about 5 minutes.
The study is designed to evaluate the diagnostic performance and safety of TES HT100 when used in addition to standard emergency care. Participants undergo routine clinical assessment and brain CT according to usual clinical practice, and the TES HT100 examination is performed as an add-on procedure. The reference standard for performance evaluation is the brain CT report. TES HT100 is not intended to replace standard clinical assessment or CT imaging.
To reduce interpretation bias, the TES HT100 examination is performed by trained personnel who do not have access to the CT report at the time of testing, and the radiologist interpreting the CT scan is blinded to the TES HT100 result. TES HT100 examinations are performed within 24 hours before or after CT, according to site workflow.
The investigation plans to enroll approximately 850 participants overall across two clinical cohorts. The study duration is planned to be 30 months. Three TES HT100 devices, one per participating center, will be used under the same qualification and maintenance procedures.
In addition to diagnostic validation against CT, the study includes safety monitoring during device use and an exploratory assessment of the potential clinical utility of TES HT100 in emergency department triage and resource management. The overall objective is to generate clinical evidence on the performance and safety of TES HT100 as a rapid, non-invasive screening support tool in the emergency setting.

Kísérleti: TES HT100 Examination
All enrolled participants receive standard emergency department evaluation, including head CT according to usual clinical practice, and undergo an additional TES HT100 examination as an add-on procedure. TES HT100 is evaluated against the head CT report used as the reference standard. The study includes adults with mild head injury and adults with neurological symptoms not related to head trauma and not in a critical or life-threatening condition. |
A non-invasive, add-on diagnostic examination performed with the TES HT100 device to assess the presence or absence of intracranial abnormality in adult emergency department patients. The device uses ultra-low-power, non-ionizing electromagnetic waves in the 500-6500 MHz range and provides a binary on/off result. The examination lasts about 5 minutes, does not require direct contact with the patient's head, and is performed by trained personnel in addition to standard clinical evaluation and head CT. |
