Diffusely impaired myocardial perfusion in patients with suspected coronary artery disease: Clinical utility of relative perfusion

Clinical Physiology and Functional Imaging, Volume 46, Issue 6, November 2026.
Abstract Background In patients with suspected coronary artery disease (CAD), diffusely impaired hyperaemic myocardial blood flow (MBF) may indicate a multivessel epicardial CAD but also impaired coronary microcirculation. We assessed whether relative hyperaemic MBF—that is, the ratio of the lowest to the highest regional hyperaemic MBF—predicts ...

Two birds with one stone: pre-TAVI coronary CT angiography combined with FFR helps screen for coronary stenosis

BMC Medical Imaging
Objectives Since coronary artery disease (CAD) is a common comorbidity in patients with aortic valve stenosis, invasive coronary angiography (ICA) can be avoided if significant CAD can be screened with the non-invasive coronary CT angiography (cCTA ...

Coronary CT angiography—future directions

Cardiovascular Diagnosis and Therapy, 2017
Clinical applications of coronary CT angiography (CTA) will typically be based on the method´s very high sensitivity to identify coronary stenosis if image quality is good and if the pre-test likelihood of the patients is in the lower range. Guidelines of national and international cardiac societies are starting to incorporate coronary CTA into their ...

15O‐water PET‐detected myocardial ischaemia and CT‐derived FFR: Predicting the functional significance of anatomical stenosis

Clinical Physiology and Functional Imaging, Volume 46, Issue 6, November 2026.
Abstract Aims Coronary artery disease (CAD) is a major cause of morbidity and mortality worldwide. While coronary computed tomography angiography (CCTA) provides anatomical assessment of coronary stenoses, its ability to determine their functional significance is limited. Computed tomography‐derived fractional flow reserve (CT‐FFR) has emerged as a non‐

Diagnostic performance of coronary CT angiography by using different generations of multisection scanners: Single-center experience

, 2008
Purpose: To retrospectively compare sensitivity and specificity of four generations of multidetector computed tomographic (CT) scanners for diagnosing significant (>= 50%) coronary artery stenosis, with quantitative conventional coronary angiography as ...

Carotid artery dissection linked to intermittent apnoeic swimming: A case–control study

Experimental Physiology, Volume 111, Issue 11, Page 4966-4978, 1 November 2026.
Abstract Internal carotid artery (ICA) dissection is a rare and potentially devastating cause of cerebral ischaemia, initiated by an intimal tear or rupture of the vasa vasorum, that can lead to an intraluminal thrombus, vascular stenosis, occlusion, or dissecting aneurysm formation.
