Coronary artery calcification on routine CT has prognostic and treatment implications for all ages.

Aims: Guidelines have recommended reporting coronary artery calcification (CAC) if present on chest CT imaging regardless of indication. This study assessed CAC prevalence, prognosis and the potential clinical impact of its reporting.

Methods: We performed a single-centre retrospective analysis (January-December 2015) of 1400 chest CTs (200 consecutive within each age group: <40, 40-49, 50-59, 60-69, 70-79, 80-89, ≥90).

Assessing splenic switch-off in Adenosine stress CMR for patients with atrial fibrillation: a propensity-matched study.

Objectives: Splenic switch-off (SSO) is a validated indicator of adequate vasodilator stress unique to adenosine stress cardiac MR (CMR). Patients in atrial fibrillation (AF) may have a reduced adenosine response due to lower hyperaemic coronary flow reserve and may achieve SSO less frequently versus sinus rhythm (SR).

Methods: 1100 stress CMR studies were identified from a clinical CMR database (2016-2021).
