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.

VIDEO: The role of AI in cardiac imaging

Ed Nicol, MD, president-elect of the Society of Cardiovascular Computed Tomography, provided us with an exclusive look at how AI is expected to change cardiac imaging.

Triplet pregnancy fetus in fetu: A rare case report

While FIF is an extremely rare condition—occurring in about one in 500,000 births—it is even more rare in triplet pregnancies.

Digitized informed consent increases detection of critical 'red flags' prior to imaging exams

Digitized informed patient consent prior to contrast-enhanced CT exams has significant advantages over traditional paper consent forms, but it also has the unfortunate effect of leaving some of the most vulnerable patients behind.  

long covid lung CT

More than half of long COVID patients have abnormalities on chest imaging

Nodular patterns were the most commonly visualized abnormality, although several others were observed.

Left, HeartFlow's RoadMap analysis enables cardiac CT readers to identify stenoses in the major coronary arteries. The AI provides visualization and quantification of the location and severity of anatomic narrowings. Right image, HeartFlow's Plaque Analysis AI algorithm automates assessment of coronary plaque characteristics and volume on CCTA exams to greatly reduce the time it takes to manually assess and quantify these features.

HeartFlow gains FDA clearance for 2 new AI-powered imaging assessments

The solutions, Plaque Analysis and RoadMap Analysis, both use coronary CT angiography to provide clinicians with a noninvasive look at patients who present with coronary artery disease and face a heightened myocardial infarction risk.

CRC patients with these clinical characteristics need more frequent post-op chest imaging

These patients are at greatest risk of developing lung metastases within three months of surgery.

Total body PET/CT scans may offer benefits for evaluating arthritis

Low-dose scans showed high agreement with joint-by-joint rheumatological evaluations. 

 

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.”
