Computed Tomography

Computed tomography (CT) is a fast and accurate imaging modality often used in emergency settings and trauma imaging. CT scans, with or without (or both) iodinated contrast are frequently used to image the brain, chest, abdomen and pelvis, but also have post-imaging reconstructive capabilities for detailed orthopedic imaging. It is now a standard imaging modality in emergency rooms to quickly assess patients. CT uses a series of X-ray images shot as the gantry rotates around the patient. Computer technology assembles these into into a dataset volume than can be slices on any access, or advanced visualization software can extract specific parts of the anatomy for study.

Women at higher risk for COPD thanks to smaller airways, even if they’re nonsmokers

Differences in airway size, combined with increased urbanization and changes in smoking rates, can help explain the growing prevalence of COPD in women. 

VIDEO: 3 challenges for Society of Cardiovascular Computed Tomography members in 2023

Society of Cardiovascular Computed Tomography (SCCT) President Brian Ghoshhajra, MD, detailed three challenges he is making to SCCT members in the coming year. 

Ron Blankstein, MD, MSCCT, associate director, cardiovascular imaging program, director, cardiac computed tomography, Brigham and Women's Hospital, and professor of medicine, Harvard Medical School, was a co-author on the ACC 2021 Chest Pain Guidelines,[1] which now lists coronary computed tomography angiography (CCTA or CTA) as a 1A level recommendation for front line imaging. He gave an overview of the guidelines during the 2022 Society of Cardiovascular CT (SCCT) meeting in July. #SCCT2022

CT imaging alone found noninferior to CT/MR combo for acute ischemic stroke patients

“The value of MRI added to CT in patients such as these should not be presumed."

Positron, a New York-based nuclear imaging company, will now provide Upbeat Cardiology Solutions with advanced PET/CT systems and services. 

The nuclear imaging isotope shortage of molybdenum-99 may be over now that the sidelined reactor is restarting. ASNC's president says PET and new SPECT technologies helped cardiac imaging labs better weather the storm.

CMS has more than doubled the CCTA payment rate from $175 to $357.13. The move, expected to have a significant impact on the utilization of cardiac CT, received immediate praise from imaging specialists.
