Ultralow-dose CT matches chest radiography radiation dose
By Brian Casey
Thursday, November 29 | 11:20 a.m.-11:30 a.m. | SSQ03-06 | Room S405ABRecent advances in iterative reconstruction have put CT radiation doses within range of those found in chest radiography. So is ultralow-dose CT a realistic alternative to x-ray for chest studies? Researchers from Rikshospitalet at the University of Oslo wanted to find out.
