Article Synopsis
- The lung clearance index (LCI) in adults with cystic fibrosis (CF) indicates differences in how air moves through the lungs, relating to both acinar and conductive ventilation.
- Researchers found a connection between LCI and how many bronchial segments are affected by bronchiectasis, confirming this in CF patients and another group with non-CF bronchiectasis.
- They concluded that the severity of lung disease, measured by the number of impacted bronchial segments, leads to a rise in LCI that may not improve with treatment in CF patients.
Objective: To retrospectively compare image quality of a lowered dose CT protocol to a standard CT protocol in children with suspicion of craniosynostosis.
Methods: Forty-eight patients (age 0- 35 months), who presented with a cranial deformity underwent cranial 3D CT to assess sutural patency: between 2009 - 2010, 24 patients were imaged with a standard protocol (CTDIvol 32.18 mGy), from 2011-2012, 24 underwent a low dose protocol (0.
Purpose: To investigate a computed tomographic (CT) protocol with iterative reconstruction at conventional radiography dose levels for the assessment of structural lung abnormalities in patients with cystic fibrosis ( CF cystic fibrosis ).
Materials And Methods: In this institutional review board-approved study, 38 patients with CF cystic fibrosis (age range, 6-58 years; 21 patients <18 years and 17 patients >18 years) underwent investigative CT (at minimal exposure settings combined with iterative reconstruction) as a replacement of yearly follow-up posteroanterior chest radiography. Verbal informed consent was obtained from all patients or their parents.
