Nonsolid lung nodules carry greater cancer risk in women
November 24, 2015 -- For lung nodules detected on CT, certain types can pose a higher risk of cancer for women than men, according to a study to be presented at the upcoming RSNA 2015 meeting in Chicago. The results indicate that radiologists may want to consider gender when interpreting CT lung screening scans.
Lung cancer or valley fever? CT can spot the difference
November 16, 2015 -- Characteristics seen on CT chest scans can enable physicians to distinguish between lung nodules caused by fungal infections such as valley fever and those caused by lung cancer, according to a poster presented at the recent American College of Chest Physicians annual meeting.
Automated tube current selection cuts CT radiation dose
November 16, 2015 -- Automated tube current selection reduced dose significantly in CT scans acquired at dozens of centers worldwide, according to the results of a large international study published in Radiology.
Negative CCTA scan means ED patients can be discharged
October 27, 2015 -- Patients presenting to the emergency department (ED) can be safely discharged if their coronary CT angiography (CCTA) scans are negative, without fear of major cardiac events occurring up to a year later.
CT lung cancer screening puts patients on edge
October 26, 2015 -- CT lung cancer screening is associated with high distress levels in nearly half of patients who are screened, according to a study to be discussed on October 28 during the Chest 2015 annual meeting in Montreal.
Hybrid lung CAD scheme improves accuracy
October 23, 2015 -- A hybrid computer-aided detection (CAD) algorithm for lung nodules showed high sensitivity with very few false positives, according to new research in Medical Physics.
JNCI: CT screening beneficial in shorter-term smokers
October 20, 2015 -- Data from a large study show that CT lung cancer screening may benefit even those with fewer than 30 pack-years of smoking history, according to an October 19 article in the Journal of the National Cancer Institute. The findings could potentially open up screening to millions more smokers, especially women and minorities.
How CT unraveled curiosities of King Tut

Study finds emergency CT use leads to diagnosis changes
October 9, 2015 -- A new study in Radiology is offering a riposte to those who question whether CT is being overused to evaluate patients in the emergency department. The review of more than 1,200 patient cases found that the use of CT often led to changes in patient management.
Study: Skip CT in most blunt emergency trauma cases
October 7, 2015 -- Doctors can safely forego CT imaging in more than one-third of emergency blunt trauma cases by using clinical criteria to assess patients rather than automatically sending them to imaging, according to a study of more than 11,000 patients that was published October 6 in PLOS Medicine.
