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.

AI system boosts intracranial hemorrhage detection

“This study implies that future clinical workflows may see AI be used in an adjunct capacity to improve interpretations of CT scans by helping call radiologists' attention to findings that may be overlooked.” 

VIDEO: Cardiac CT as a front-line chest pain exam in the ED

Harold Litt, MD, explains the use of cardiac CT as a primary imaging exam for chest pain at his emergency department over the past decade.

Radiologists are overlooking signs of pancreatic cancer on imaging more and more, new study indicates

The research revealed that 7.7% of patients screened for pancreatic cancer had their tumors missed on initial imaging exams but were diagnosed with cancer between three and 18 months later.

Current LDCT eligibility criteria leave women and minorities behind

Compared to USPSTF 2013,  modified eligibility criteria could increase cancer detection by 37%.

Radiomics-based models can detect pancreatic cancer well before clinical diagnosis

Recently a radiomics-based machine learning model proved highly accurate at predicting which patients would develop pancreatic cancer three to 36 months after abdominal CT imaging.

How breast cancer screening could increase lung cancer screening compliance in eligible women

Breast cancer screenings present an additional opportunity to identify more women who would also qualify for lung cancer screening, authors of a new paper in JAMA said.

What factors impact reader variability the most? New research offers insight

A new paper in Radiology explores factors that can lead to reader variability in CT imaging, from the radiologist’s experience level and subspecialty to navigation patterns and time spent interpreting.

New lesion measurement assesses treatment responses more accurately than RECIST

Researchers believe the new method of assessing treatment responses could pave the way for developing new cancer therapeutics.

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.
