Cardiac Imaging

While cardiac ultrasound is the widely used imaging modality for heart assessments, computed tomography (CT), magnetic resonance imaging (MRI) and nuclear imaging are also used and are often complimentary, each offering specific details about the heart other modalities cannot. For this reason the clinical question being asked often determines the imaging test that will be used.

CT procedure shown to reduce need for invasive cardiac testing
In a study, CT-FFR was shown to reduce the need for invasive tests to measure coronary artery blockage from 74.5% to 25.5%.
First-in-human trial shows potential of guiding CABG with cardiac CT and AI—no ICA required
An independent heart team blinded to ICA results was able to deliver helpful guidance for CABG procedures for 99.1% of patients using just CCTA and FFR_CT alone. This approach is safe and feasible, researchers wrote, and the next step is to gather additional data.

Radiology AI company gains FDA clearance for new CT offerings focused on PE, stroke
The newly approved AI models are designed to improve the detection of pulmonary embolisms and strokes in patients who undergo CT scans.
SPECT still has an important role to play in nuclear cardiology
"I see, at least for the next decade, this being a SPECT and PET world, not one or the other," explained Tim Bateman, MD.

Due to scattering of the X-rays when they hit the lower end of the patient bed, exposure in mainly to the lower body of the interventional echocardiographer performing transesophageal echocardiography. The green lines are the scattered photon trajectories calculated by Monte Carlo simulation in the study.

What is the ROI for upgrading nuclear cardiology labs?

Some nuclear cardiology labs are still using SPECT systems that are 20-25 years old. Is it time to make an upgrade?
