詳細な説明
The advent of a new generation of CT systems based on photon-counting detector technology is raising great interest in the medical community, anticipating a major improvement in numerous clinical applications including chest disorders. These expectations are drawn from the technological advantages inherent to these new CT systems, including a higher contrast-to-noise ratio, higher spatial resolution, and lower radiation dose together with the potential of multienergy imaging.
Non-contrast enhanced CT will be acquired in spectral ultra-high-resolution mode on a clinical dual-source photon-counting detector CT (PCDCT) (NAEOTOM Alpha, Siemens Healthineers AG, Forchheim, Germany). All scans will be acquired with automated exposure control.
Recent evidence showed that images obtained with PCDCT allowed a more precise depiction of CT features of ILDs with similar radiation dose. Subjective visualization of specific IPF features, such as reticulation and traction bronchiectasis, using PCDCT has been rated superior to conventional HRCT. Thus, a more precise delineation of fine fibrotic abnormalities could modify the categorization of ILD patterns and improve the diagnostic confidence of IPF and not-IPF diagnosis, reducing the prevalence of unclassifiable ILD.

調査対象母集団
Adults patients with a new diagnosis of ILD referred to the outpatient clinic of ILD of Humanitas Research Hospital, Rozzano - Milano) and with the need of a MDD discussion to reach a diagnosis will be enrolled.
MDD will be leaded by two pulmonologists with 5 years of experience in ILDs. Each MDD session will include at least one additional pulmonologist, two thoracic radiologists, one thoracic surgeon, one thoracic pathologist, one rheumatologist, and at least two fellows in respiratory medicine. MDD meetings will be held every week and lasted approximately 60 minutes.
Patients will be discussed using a standard case report form. Two diagnosis will be collected: the first diagnosis will be collected using the HRCT scan imaging. The second diagnosis will be collected using the PCDCT scan imaging.
説明
Inclusion Criteria:
- ≥ 18 years of age
- Any gender
- Any race
- Signed informed consent
- ILD diagnosis with the need for a multidisciplinary discussion
Exclusion Criteria:
- Patients with acute exacerbation of ILD
- Interstitial abnormalities that could be explained by causes different than ILD (e.g.: heart failure; viral)
