3D Landmark scout imaging accurately assesses presence and extent of coronary calcification with lower radiation exposure.

Background: Cardiac CT for coronary artery calcium (CAC) scoring exposes patients to 1 ​mSv of radiation. A new CT scout method utilizing ultra-low dose CT (3D Landmark) offers tomographic cross-sectional imaging, which provides axial images from which CAC can be estimated. The purpose of our study is to analyze the association between estimated CAC burden on 3D Landmark scout imaging vs dedicated ECG-gated CACS.

Dynamic lung water MRI during exercise stress.

Purpose: Exercise-induced dyspnea caused by lung water is an early heart failure symptom. Dynamic lung water quantification during exercise is therefore of interest to detect early stage disease. This study developed a time-resolved 3D MRI method to quantify transient lung water dynamics during rest and exercise stress.

Imaging gravity-induced lung water redistribution with automated inline processing at 0.55 T cardiovascular magnetic resonance.

Background: Quantitative assessment of dynamic lung water accumulation is of interest to unmask latent heart failure. We develop and validate a free-breathing 3D ultrashort echo time (UTE) sequence with automated inline image processing to image changes in lung water density (LWD) using high-performance 0.55 T cardiovascular magnetic resonance (CMR).

Atypical chest discomfort in a 36-year-old man.

This article focuses on aortic aneurysms and the evaluation of patients with atypical chest pain. A complete and accurate family history is essential. Clinicians should pay close attention to persistence of symptoms and age in patients with atypical chest discomfort who do not have routine confirmatory cardiac findings.
