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.

Significant variability found in pediatric CT imaging interpretations
Such discordance between pediatric and general radiologists could result in care delays and treatment changes.
AI bests radiologists at predicting lung cancer treatment responses
More accurate response assessments could give providers an opportunity to proactively manage treatment decisions in the future.
FDA clears AI solution for identifying large vessel occlusions on CTA
If left untreated, LVOs can cause ischemic strokes. The algorithm has the potential to significantly reduce time to treatment in these emergency scenarios.
Beyond just nodules—model uses all low-dose CT data to make long-term lung cancer risk predictions
New findings published in RSNA's Radiology highlight the shortcomings of using nodule characteristics and patient history alone to predict an individual’s true cancer risk.
‘Direct-to-patient’ digital prompt boosts CT lung cancer screening uptake
Researchers with two academic health systems recently tried a new approach to increase LDCT uptake, reaching patients electronically outside of a regular appointment and asking them to request a screening.

Souped-up primary care model boosts timely follow-up after abnormal cancer screening results

The “multilevel” intervention involved EHR reminders, patient outreach and navigation to encourage individuals to return following breast or lung imaging.

Top trends in cardiac CT from SCCT 2023

Cardiac CT has been evolving rapidly in recent years. Brian Ghoshhajra, MD, outlined some of the main trends he has seen at the 2023 annual meeting of the Society of Cardiovascular Computed Tomography.

Video interviuew with Ginger Biesbrock, DSc, PA-C, FACC, executive vice president of MedAxiom, on the "Financial Impact of Cardiac CT to the Cardiovascular Service Line" report at SCCT 2023. #SCCT #YesCCT #Medaxiom

Cardiac CT's financial impact on the cardiovascular service line

Implementing cardiac CT can make a big impact across the service line without reducing the use of other modalities. Ginger Biesbrock, MedAxiom's executive vice president, explained these findings in a new video interview.

Mark Rabbat, MD, director of cardica CT at Loyola, discusses legislative advocacy efforts by SCCT to gain wider reimbursement for cardiac CT. #SCCT #SCCT23 #SCCT2023

SCCT hopes to increase cardiac CT reimbursements through advocacy

Mark Rabbat, MD, discusses the Society of Cardiovascular Computed Tomography's efforts to make an impact by lobbying in Washington.

Use of CTPA for suspected pulmonary embolism in pregnancy surges 156% at 2 hospitals

Despite the marked increase, there was no corresponding uptick in either positive PE readings or pregnancies, experts detailed.

National Cancer Institute charts ‘alarming’ drop in cancer diagnoses

The decreases appeared to be greatest for cancers typically diagnosed via screening, including breast, lung and colorectal cancer.

AI-powered stroke triage software meaningfully reduces treatment times, randomized trial finds

The investigation also used secure messaging, allowing clinicians to receive real-time alerts via their smartphones to notify them of a possible LVO minutes after the completion of a CT.

15% of lung-resection surgeries are performed on benign nodules, with AI a potential remedy

More conservative approaches should be considered before direct referral to surgery, experts urged in the journal of Clinical Imaging.
