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.

Hospital leverages radiology waiting areas to boost cancer screening rates

Boston Medical Center has sought to have patients self-identify for lung cancer screening, administering multilingual surveys while they wait for imaging appointments. 

The U.S. Food and Drug Administration (FDA) has cleared HeartLung Corporation's AI-CVD, an artificial intelligence (AI) algorithm that looks at 11 different opportunistic health screening assessments on chest CT exams ordered for any reason.

FDA clears opportunistic AI for detecting cardiothoracic issues in CT scans

“Coronary calcium revealed long ago that atherosclerosis begins well before symptoms. AI-CVD extends that insight by enabling systematic identification of patients who are unaware of their cardiovascular risk using CT scans that already exist,” said Arthur Agatston, MD.

AI-CVD is a quantitative imaging tool that uses computed tomography images to identify and quantify a myriad diseases. 

Mirvat Alasnag, MD, FACP, FACC, FSCAI, FSCCT, director of catheterization laboratory and research, King Fahd Armed Forces Hospital, Jeddah-Saudi Arabia, Ditrector of TCT Middle East, and member of Society of Cardiovascular CT (SCCT) Education Committee, explains how the society it translating its educational content into other languages to help a wider international audience of clinicians. SCCT is working to expand its international membership and this is a big part of that strategy.

SCCT expands CCTA education overseas

SCCT has made it a priority to help clinicians from all over the world learn more about CCTA as the modality continues to transform patient care.

Imaging providers must act to preserve higher CT pay, American College of Radiology warns

CMS previously announced it was temporarily reassigning payment codes for coronary CT angiography, resulting in a 104% higher technical fee. 

Mirvat Alasnag, MD, FACP, FACC, FSCAI, FSCCT, director of catheterization laboratory and research, King Fahd Armed Forces Hospital, Jeddah-Saudi Arabia, director of TCT Middle East, and member of Society of Cardiovascular CT (SCCT) Education Committee, outlines why coronary CT angiography (CCTA) imaging will likely be a paradigm shift in cardiology, and where the gaps remain to gather more clinical evidence.

CCTA continues to transform cardiac imaging, interventional cardiology

Mirvat Alasnag, MD, spoke to Cardiovascular Business about CCTA's growing influence in cardiology.
